A blind man can see the PCV valve is directly on the inlet manifold, if the ''garage mechanic'' was a mechanic the first thing he should have done was remove the PCV valve, blank the manifold hole off and run the engine, then he would have seen the carbs would have tuned perfectly and the smoke would have soon stopped, been there and done that myself on more than one occasion.

Really like the channel. Very interesting. As a fully qualified veteran motor engineer dating back to the 1972 era I was weened on early Fords and all things BMC and beyond. Setting up MGB's, Mini Coopers, Lotus Cortina's, 'E' Types, Triumph TR's & P.I's and anything else that had a multiple carburettor/ induction set-up was right up my street and something I specialised in on a daily basis utilising my trusty Sun Tester 1120 diagnostic machine of the period.🙂 These PCV valves on the MGB's & Mini Coopers/'S' were always a very neglected service item. First job on any such vehicle with a running problem was to strip and clean these out, check the hoses for internal collapse and splits then reassemble and test with a new rubber diaphragm. Inlet manifold leaks, worn S.U throttle spindles, poorly adjusted dwell angle, timing and carburettor balancing/tuning will cause all sorts of running issues and in this particular scenario inappropriate wear/bedding in of newly machined components. The concern your client is complaining about has got nothing whatsoever to do with your engine machining and rebuild. It appears to be entirely due to installation of poorly maintained/calibrated ancillaries such as carburettors and the way the engine has been set up/tuned on completion. The oil contamination, shadowing on the piston rings and bore glazing of a newly machined engine are all classic signs of over fuelling/poorly tuned engine. This scenario is no different to having new tyres fitted to a car and then taking it back to the tyre shop 20 miles later complaining about a puncture!!🙄 Please, don't stand for any such buck passing or BS. All the best

Good on you mate for Not taking on useless sponsors . Youre a Very Honest man and we Love that about you . Last thing you or anyone want is to see you go down that road and end up losing the most important thing, something money cant buy ..... Respect and Trust . Cheers

I agree about not sending the engine back to the garage in parts - who knows what they will do during re-assembly and the customer is caught up in the middle not knowing what is going on or why!

The only issue with an 'independent' inspection is that there opinion depends on whose paying.

So a 30 thou rebore in order to clean the bores up correctly and new pistons with rings that don't look like thrupenny bits, and new crankshells, hopefully fitted with something like Graphegene or similar assembly paste to prevent galling. But at least you got the crankshaft the right way round for them this time 🤣

A new PCV valve is about £70, why doesn't the customer just replace the thing?

As an auto electrician, carly "diagnosing" something is as likely as refacing with a bastard file.

loved watching the engine build.

Those top compression rings on the mgb show classic overfuelling marks because the excess fuel dilutes the oil it causes ring and bore ware usually mainly at the top of the bore if unchecked for a while you end up with the piston vertical groove wearing and that makes for all kinds of problems with oil consumption. Its vital that you get the valve under control and the carbs set correctly otherwise a rebuild will waste your time and money

Lee, I am not a licensed mechanic nor do I play one on TV, but considering the very low mileage on the engine and the fact that it was running so rich that the colorization on the rings indicates that they haven't yet broken in and that along with the broken PCV could account for the smoking problem. So until the rings break in and a new PCV is installed the damn engine is going to pump oil into the combustion chambers and burn it i.e. smoke.

When an engine is running very rich at higher throttle positions fuel will go down the bores, the bores will glaze and the rings will wear precisely in the way those shown in the video have. There was clearly nothing wrong with your engine build, whatsoever. They caused ALL ISSUES THEMSELVES by the faulty valve and the associated mistuning of the carbs. Still I don´t think it looked all that serious. A functioning valve, properly tuned carbs, new oil and that engine would have worn in quite alright, and ran fully well for many years.

Bought a Carly code reader a long time ago, but my MG is not evan on the list, so need to check before buying, thanks to the inspector, for independent assesment

This video needs Paul McCartneys Check My Machine playing when there’s a Barum Balls Up or perusal of interest

Another great video Lee. I just wanted to let you know that I like the new picture of the blue engine as Barum engine logo!!

Interesting stuff enjoyed keep up the good work 👍

Cut out the waffle and test the pcb valve. It simply acts due to differential pressure across the top and bottom of the valve diaphragm, so it doesn't care whether it is on the engine, under vacuum, or anything other than the pressure being up the 1bar higher on one side compared to the other. So put it on an air compressor with normal air pressure on one side and normal air pressure plus up to 1bar on the other side. Then compare what it does as with a brand new valve. 1.8bar = overrun; 1.4bar=idle/cruise;1bar =wot, all assuming you have 1bar on the other side of the valve. The fact that it is "sucking" when on the engine but you are testing by "pushing" on the other side is irrelevant -it's the differential in the pressure on both sides which makes it open or close.

Back in the late 60s, early 70s, new Volvos were equipped with Zenith-Stromberg carbs. We had a rash of brand-new engines flooded with gasoline due to faulty float bowl valves. Even after changing the oil and installing new float valves, these new engines often consumed too much oil and had to be re-ringed. Lots of irritated owners that wanted new engines.

Thanks guys! Carly...wow where is it all heading.

On the e90, the fault is more than likely rusty scabs on the rear outer drive shaft joints causing the abs reluctor rings to swell. This causes the air gap from the wheel speed sensor to disappear.

MGB - there are about three different dipstick/tube in block combinations, and things can get mixed up together over time.. Shove the sump etc on, and put the exact of amount of oil in, and see what the dipstick says. Can tell then if overfilling has been happening..

Happy 4.08pm Friday to you too Lee

Got an independent inspector in to smell the oil. He said it could be anything. Money well spent.

Regardless of what the engineer says, I know for a fact any and all the problems on the engine stem from the pcv valve, I've seen this a good few times back in the day. It's a crying shame you'll end up out of pocket but if the customer is a decent fella I can understand why you feel the need to do right for him. Those rings would probably still bedded in fine if the fueling was sorted, but what can you do in this position.

if the inspector comes in and favors the engine problem caused by the customer, then the bill is the customers inc strip down charges

Oil viscosity, Oil quantity, and needle position in the SU carb slide valves would be something to investigate. Been there done that with my MGB and Midgets/Sprites.

There's nothing wrong with doing sponsor ads. I appreciate that you want to keep the sponsors down to industry related stuff though. Anything but RAID SHADOW LEGENDS.

Hi Can't remember if I said it before about the mg's oil it's very black for only 59 miles that doesn't happen with a clean build did somone use an oil additive like molyslip? If so that would prevent proper bedding in of the ring pack

My MGB engine exhibited a similar problem caused by fuel wash. Diagnosed by a step worn in the top ring. The excessive fueling may have been caused by the PCV. An ex-Abingdon employee had dealt with several engines like this. His suggestion was to re-ring and run the engine in with a lot of throttle!

+1 on the over fueling. While the fuel in the oil is continuously evaporating while the oil sample is exposed to open air, sending the oil in for analysis by a laboratory would tell you very quickly as to whether or not there is a high level of fuel in the oil. If there is a load of fuel in the oil, that clears your name.

Hi Lee, that oil should be almost as clean as it came out container with 50 miles on it, the over fueling causes bore washing, making the oil so dirty so quickly. if it was the rings the oil would be still clean ish, in the 70s i used gunson glass spark plugs, carb balancers and a Ti crypton tuner, to set engines up, worked a treat, now there is a lot of guess work tuners out their when it comes to older engines. no plug ins for laptop tuners.😁

Halfway through your promo I got an advert for Sainsburys! 😠

Also crankcase pressure problems can make the dipstick hover if bad enough. MGB.

So the advert for how great Carly is showed a fault code that is either a) steering angle sensor b) lateral acceleration sensor or c) a rear wheel speed sensor. At least if you asked on a facebook group, each person would only give you one guess. It's generally a great example why you'd want to throw carly in the bin.

Re the MG engine. Is the block pocketed? And yes do check the dip stick and if it has an oil cooler. We had one that was burning oil and the pockets on the block in conjunction with the style of piston the engine builder used, meant the top ring was above the pocket allowing oil to be burnt. The other issue we had which was an oil pressure issue was that the dipstick was wrong and therefore the engine didn’t have enough oil in it and despite a baffled sump, it meant the pick up didn’t have any oil to pick up under heavy braking and cornering.

Oil through the inlet tract, is not as issue. Put a new finnish on the bores, pop it back together. Run the car up on a dyno for an hr, increase the load and rpm. At the end of an hr that old mgb should be giving 60ish hp by 4000 rpm. Check for leaks etc. Re- set the idle and mixture. Send it out, for the guy to enjoy. All those problems have been caused by folks playing when they shouldn't

Do you use torque plates when honing the block? If not, you will have block distortion when the head is installed. Then the rings can not seal in an out of round cylinder.

Lovely to see more torque and less talk.

If the breathers are not working then this can pressure the crankcase forcing oil past the rings I had a rover doing this it just needed the breathers sorted

ring tension does not create the psi needed for the sealing/bedding of the rings psi(from combustion) does I would give him a set of rings, require a good PCV (the cause of the glazing and shape rings due to over fueling), check the dipstick length, and charge him for the refresh

Ring wash. Fuel in the oil. PVC definitely. Carry on

Wow! ( regarding the warranty issue ) I can not really understand how much Farer you could be, you have nearly bent over backwards to investigate and or resolve the issue or issues with this engine. For me from my own personal experiences from using engineering shops, I feel they could learn a lot from you, ie in how to use your negotiation skills in warranty claims.

How's this fit your breather engine. *Breath valve broken so carbs set rich. *Rich mixture dilutes oil and the rich soot changes oil colour and gives you bore washing. *Bore washing marks the rings and glazes the bores. *Thinner oil will get burnt more easily adding to the valve also breathing heavily from its broken parts. The extra fuel will also smell in the petrol. I dud something similar when i over jetted a carb, and the engine started breathing more heavily, fixed after rejet and oil change, oil had been new to start with.

Good vid question is forte liquid good for engines bmw in particular thanks

Any good mechanic who put a new engine in a car that had blue smoke on the overrun would go through the whole breather system anyways as a matter of diagnosing to see if it's functioning correctly and should have known there was a problem when he couldn't set up and balance the carbs even just blank off the inlet manifold where the PCV valve attaches to, then take it for a run to see if it smoked on overrun and see if he could balance the carbs and set the mixture.

I really like watching your Chanel Lee and I’ve been a sub for ages now. I’m starting to get the impression that some customers are jumping on the warranty / claim bandwagon, I don’t like getting an independent opinion to scrutinise your work because if you and your Barum engine team are 100% confident and happy with your work send the moaning customers packing your not going to loos in the long run because them types of customers are worthless to any business 🤷‍♂️

Are OBD systems (connections on up) the same in Europe and the U.S.?

I would advise you to remove that PCV valve. After I had my car overbored to 1933cc it would never stop smoking. It seemed to fill up with oil on a light throttle then dump into the inlet manifold as you accelerated, like a smokescreen. Cleaning the valve, fitting a new one and changing to the later style tappet chest collector cover had no effect. It now has a small Pipercross filter over the breather with the pipe run so oil will drain back into the crankcase plus obviously the port on the manifold sealed. It works well, you don't get crankcase fumes it doesn't burn oil and the crankcase isn't pressurised. I wouldn't recommend taking MGB engine bores out that far now, I think the block lozenges a bit at high BMEPs.

What oil was used ?

Interesting things here. I hope to see the MGB engine clearly sorted out. If all the machining clearances are OK, then it must be an external valve/breather problem. On a technical point, The torque is not foot pounds, it is pounds feet! I know many call it foot pounds, but torque is force x distance. You call the metric equivalent correctly as Newton Metres which is Force x distance.

Am I missing something here??? Surely by disabling the PCV valve and venting it to atmosphere would prove whether that's the smoke issue ???

We had loads of smoking problems from early MGBs with the diaphragm breather valves when the diaphragm rips. But however I have noticed on your valve on the inlet manifold has a tooth missing ( broken off) there should be four. This will cause a misalignment of the internal valve.

It seems the inspector added nothing. Interested to see if you find anything wrong with your work, personally I doubt it, especially when you know there is a serious fault elsewhere. Id be astonished if the pcv was corrected there was still a problem.

How long will that plastic timing chain guide thing last? Toyota 22re lasts about 180,000 miles.The replacement part is metal.

Problem with doing rings and pcv valve is that you won't pin down the smoking gun, literally.

Do you give your customers compression test readings with re worked engines?

I would like to know how much the vr6 rebuild cost

Carly is great. But what if I want to check a cars history before buying it? Vertically? Or surf the Web like a shark?

My Audio All OK

Where is the link

I think the engineer was a bit overly generous to the customer here, especially since that super rich running probably explains that slightly odd ring wear.

Uh-oh! "Problem with the Dynamic Stability Control"...that's the driver! It's fully understandable for the need of a sponsor to cover your costs for producing this channel. And I agree, if that's to be done, then best it be something you use and recommend whether sponsored or not. Carly is actually a very usable product, and they chose you well as you chose them. It's perfectly in tune with your viewers. Kudos on your diplomatic and professional response on the MGB. You look good on that. And on that point, you look younger and fitter since your knee-op. Sometimes these things can be a tap on the shoulder to take better care of yourself. You look ten years younger! Paul's VR6 vid is deeply satisfying. Smoother movement of the cam, excellent dialog, excellent job.

is that engine considered a straight 6 or a V 6

ARP studs torque-to-yield? That "turn another XX degrees" is procedure for TTY bolts which they want to stretch to X dimension.

The fuel might have preferred one side of the cylinder washing away more oil on that side, causing uneven wear.

You should some T-shirts for sale with "ITS ALL BEEN DONE" on it

One bad customer cancels out numerous good customers , as Barum Engines know its damage limitation , good practice ..

An independent inspection is just some one else’s opinion, if I was there I would give you my opinion and charge you nothing. That VR6 Tensioner doesn’t look like it will last long. Thanks for the vid.

I can't understand how anyone can disregard the state that MGB pcv is in. Its obvious it is not going to do what it is intended to and will cause problems with carburation and engine breathing. Surely the proof is the state of that oil. Also, as a matter of interest, you mentioned the length of the dipstick. The Austin Maxi engine had a tendancy to burn oil, the cure was to overfill the engine.

What's the most dangerous part on a car. . . . The "Nut" that holds the steering wheel . . . . ha ha ha ha ha ha ha

Tbh, couldn't care less about sponsor ads as I never watch those segments on YT videos...

VR6 build is very nice job so no more sweeping the floor you have done your apprenticeship😆

"Obviously"

50 miles on the clock of your mg engine plus about 2+ hours on the tuning rig maybe more either way it won’t help if it’s been left ticking over for any length of time

Mmmm the off set 6 cylinder motor.....never seen one of those before....what engine is it please anybody. Very interesting channel.

You do know if fuel is going down the bores and into the sump the bores will glaze and the rings will wear without bedding in properly. 50 miles, I still don't think it's a Barum Engines issue.

Get a oil sample done, tells you allot

Obd2 code reader is mainly for German car's but Very good to have 👍🏻,your videos are getting better and better keep it up 👍🏻😀💂🏻🇬🇧

The Carly diagnostic system is supposed to be very good. I looked at it before I bought my GAPII D system I didn't get the Carly for one reason and one reason only. They don't tell you upfront that the cost ( around £75) was a Yearly charge which I think is a bloody cheek. My GAP11 was not cheap( £400) but that's a one off payment and that's it, you can download any updates etc at any time. So I went that way. I would have rather paid £400 upfront and have done with it. That's my two penneth worth!

Surely the fact that it was smoking before and is still smoking points to the valve. Sounds like the garage bloke is covering his arse

hard call with many factors, it must not be an easy situation . i think if it were my name on the bill and in this situation.. original bill must be satisfied the work and costs were incurred. the other garage should either pay for the engineer or the new rings as it was there insistence it wasnt a pcv issue. you want to reassemble the engine so should eat those charges for the labor, but customer or other garage should be responsible for consumables . i dont think the customer should bear the majority of the new incurred costs as he got an incorrectly functioning engine and was given incorrect information as to its cause, you did what you were asked and correctly, the garage seems to be the one at "fault" they should bear the responsibility in my opinion. thanks for the videos

I really don`t understand why you, or somebody, didn`t test the PCV valve, or fit a new one, in the first place. Surely that`s the simplest and easiest thing to do first. Anyone who knows anything about A or B series engines knows that they need lots of breathing. Personally I would bin the valve and just use at least 3 breathers into a catch tank.

At 7:54 you can see that one of the four "teeth" inside the pcv valve is broken off. Where did the piece go? That piece would be perfect size to jam the valve......

I would put new rings in it, pistons and a bore if needed. Run engine on known good EGR for break in. Turn over for install Be present at start up with that same EGR if it still smokes than the problem is the EGR and they pay for all additional work and parts. If they disagree show them the break in video with good parts on a known good EGR, that is the only way to CYA and find out if you were the problem. The excessive fuel washed the walls glazing cylinder and the amount of fuel was pushing tops of rings away from wall wearing an irregular wear pattern on ring sides. The discoloration is normal wear, the shine spot on ring is cylinder wall contact also the Glazer and where there is no wear the rings were floating due excessive fuel in combination with compression being pushed past the rings and now glazed walls into the oil pan making oil excessively dirty and smell like fuel. Lucky it did not fluid lock and bead rods and more expensive parts. Had the same thing happen on a new EFI conversion, fuel washed walls glazed cylinder started smoking, rings looked just like that. Best of Luck. Oh, this an opinion, everyone has one just like everyone has a bumm and they stink! Including mine!

Great video! But damn, Carly is just a generic OBD scanner with a nicer looking software at a massive overprice.. 65Euro Those things can read faults where there are none, and can really mess up ALOT with their miss readings... Really a waste of time and money but a good sponsor. People are better served by a baseline AUTEL or iCARSOFT diagnose tool. iCARSOFT i810 for 68eur.. It reads OBDII, EOBD, CAN, ISO9141, LPW2000, J1850 VPW and J1850 PWM. Or if you like the AUTEL series more Autel Autolink AL319 is a OBDII/ EOBD ready its a really cheap one still a ok scanner, 30Euro. Perfect for the DYIer. Still waiting for more VR6 videos.

Driven 50 miles... to the chassis dyno?

Early A and B series engines just had an open swan neck tube on that crankcase followers-pushrod cover - oil mist was just dumped on the road. That and truck diesel used to dissolve tarmac roads then.

How much is this cost of that broken valve? Only dump mechanic will not replaced a broken part. Must be the pride of the mechanic needed replacement.

100 present, the brether valve, will smoke more than counsel estate chafe,😁😁😁😁😁😁 ( 40 years in job, but still learning)

Your carly gadget doesn't work on my mk1 escort or my 1990 golf rallye, i'm obd free thank god🤣

I'm surprised people are so averse to paid promotions. They are a great way to fund a channel and really easy to skip using the slider, unlike google pre roll and mid roll ads. If you wanted to shill ball shavers and crotch deodorant I'm all for it. (just wear a different colour top when you do the promo so it's easy to tell when scrubbing through when it starts and finishes). Also, have you thought of Amazon affiliate links. If you find a cool tool, add an affiliate links to the description. Who isn't into buying that life saving gadget that sits at the back of the tool box until that one time when you think 'thank truck I bought that!!!'...he who dies with the most tools wins, right?

Scratchy, uneven wear on the rings, slightly glazed bores, oil on top of the pistons, fuel odour from the oil and dirty oil all together points to fuel-washed cylinders. Every engine I've done had cleaner oil than that at 1000 miles and as you know, there shouldn't be any fuel odour to oil. The intake may be clean of oil for the same reason, fuel wash.

That treacle only done 40 - 50 miles my arse.

I couldn’t imagine trying to be in the buisness of rebuilding engines that are know to suck, at least from an an American perspective, most of our available engines can be reringed and do another 100k miles with little complaint

What you got here is just the blaming game if it was the pcv the garage is now trying to cover it's ass . 80 quid now has cost a fortune

I know that the days of the British empire are long gone but your videos are released a day ahead here in the antipodes so if you could just move your calander a day on when you introduce the video it would be much appreciated.

GOOD I HATE ADS

Why so many car keys on one bunch 🤦‍♂️

Apologises for advertising then straight into an advert = me leaving video

As they say, never buy a car of a mechanic lol 🤦‍♂️🤣
