Crank case breather!!!! Pressure builds, high rpm causes enough pressure to suck it back through the valve seals.

Bro you guys have build this thing basically from scratch, don’t be so sad about things not working straight away, give yourselves some major props! Absolute gangstas

That oil was like glitter. A magnet will only attract ferrous metals and the m60 is predominantly aluminium. Rod bearings are also usually non ferrous metals.

That smoke is blue so definitely burning oil on load, could be bad valve stem seals. Not sure if you did a compression test but that's where I'd start. Could also be bad piston rings. Both of these would cause low power and high levels of smoke. Valve stem seals usually cause loads of smoke on start up after the cars been sat for a while, so if it's relatively smoke free in the morning after a few days rest it might not be that. The age of the engine, the valve stem seals are a rubber part so hence to deteriorating even on low mileage engines. If it is piston rings, time for a built engine and then turbo it ;)

That oil was full of metal 🫣

Invested in this. Got to sort this before starting anything else. Taken all this time to get it together. See it through come too far man 😂👍🏼

I’ve literally JUST finished building an e36 m62b44 adamat kit etc. we had to block the pipe under the inlet to stop the smoking. It’s the small breather in the sump that picks up oil. Car has run mint ever since 👍🏻

Boq's black nail is going to have grown out before this gets to 50mph 🙃🤣

So it smokes the worst when you come off load. Which means something is getting pressurised and then getting into the cylinder or the exhaust when you come off throttle. So its either the crankcase is getting pressurised because the breather is broken and its forcing oil down the valve stems orr its the head gasket and it pressurises the coolant system under high load and eats coolant as you come off. Depends what it smells like and looks like. I couldnt tell from the video... good luck lads

Really sounds like its running on 7 cylinders. m60s are quite a smooth sounding refined v8. This sounds a bit lumpy, and definitely has some kind of crank case breather issue.

Work on the defender, love the off-road / adventure build

100% defender series for the summer. Trips with the boys are the best memories

dudes i"m a petrol head from the uk,been waiting for a hip replacement for 2 yrs so not been out much,lovin the vids guys and the great nosh too,hopefully when i get better i will buy a car again,i had an is200 from 2001 manuel with low miles,sadly i had to sell it due to not working and bills etc,i have never been the same,cars mean so much and after watching this i feel for you fella,

Damaged bore, blown rings or blocked breather. Definitely start with compression test and cross your fingers😂 Sick to finally see it on the road though!

i really enjoy the cooking sections so please never lose them

First BQR vid I've watched in years (I've been following since the old BMX days, pre cupra, first house etc) and maybe its because I'm about to hit 30 but I lowkey appreciated the cooking segment 😂

Love the content boys. Wish u posted more often. Understand these things rnt easy to produce. Take it steady lads x

Wish you guys uploaded more regularly. You and Andy have great chemistry on camera, and it makes for very entertaining watching. Please do more regular videos, the car stuff is fantastic.

Also boq it could be the crankcase breather. VW’s can suffer from it quite bad too when they’re hot under decel. They get real hot and then the pressure goes up to the point that eventually there’s enough to pull a bit of oil back through the valves. Worth checking that. The oil was like mr sparkle though so definitely some further investigation required. Awesome series though. Loving watching it.

Currently undergoing an issue with my starlet that I can't seem to get to the bottom of so I know how you feel. I absolutely love the fact you're documenting the low points of project cars which a lot of channels seem to gloss over. I hope you get this sorted mate

Shame about the smoke issue but still a quality video nonetheless. Loving the cooking recommendations too

loved watching this series

Just for the future: Blue smoke = oil burning. White smoke = water. Black Smoke = air to fuel ratio too rich. And as others have said, oil was full of aluminum.

More cupra R videos, just bought my first one after watching Colin for years ❤️

Love the videos, especially the cooking parts. Would love to see you guys build a ducati

Defender tour would be legit 🤟

I feel deverstaed for you! So annoying to put that work in and not get what you want or even know what the fix is!

Next vid - Defender for sure. Also, definitely need a BQR hotdog dad hat - I got excited about buying a bike rack yesterday 😅

I reckon crack on with the defender, love seeing what ideas you come up with for it!

New car, I've been looking into sports car for fun summer driving.

That smoke looked blue, I wanna guess oil, normally when it’s a head gasket it’s a constant stream, I’d wanna say piston rings may be a mouldy shegged

Would love to see this energy on a new car build! 👌🏼

waiting for the Boq’s Bites cookbook

I love this build so much yow🔥💯

Love the e36 swap content, keep it coming 👍

Get Andy's Volvo on the lift ❤

Keep your heads high boys you got this

Since other comments determined thats burning oil type smoke not burning water smoke and its only comming after redlining it i would assume its something with oil pressure. Maybe someone was playing with overdriving oil pump and now it has too much pressure causing leakage into cilinders and thats why it clears after a second? If you have already backup engine i would swap these rather than waste time tinkering with current one.

Can’t wait to see this fully built/bulletproofed etc. You guys deserve it after all the work on it over the years. And for the giveaway answer: buy another car plz.

With the V8 conversion kits you have to modify the oil pump, some times this means trimming down the oil pressure spring. Get an oil pressure gauge and check the pressure at idle, cold oil.. and hot WOT.. As for the lack of power, you probably have some sensors in the wrong place. a couple of the connectors are the same from memory.. you might have accidently mixed them up.. it would also be a good idea to get the injectors tested / cleaned .. if you have some sticking it will wash the bore and allow oil past and also run like dog shit.. it sounded like it was missing / loading up under throttle.. Check TPS wiring too.. I Forget it you fitted new cam or crank sensors, its been so long in the making haha.. If you did... test them, old bmws hate the Euro car parts cheapies.. im sure its nothing crazy... Also check the PCV system because if its only after high rpm you're pushing oil in through the breather. Good luck, don't be disheartened you've come this far boys :) if iit was catastrophic engine failure it would be smoking all the time, regardless of rpm or load.. and its not doing that!

Keep at it broski. Get the cupra ready for a track day too

I think I'd enjoy seeing work on the cupra or defender more than a new car at the min, they feel like part of the channel and always enjoy watching them get better and better :)

Mate that oil was like silver paint! There’s 100% a mechanical failure in your engine. Could be worn piston rings or something to cause poor starting, heavy smoke at high rpm on decel due to the back pressure in the crankcase sucking up the oil into the chamber and would also explain your unusually pressurised rocker cover oil leak

At least you got to feel the 300hp in the end🤣

Something sounds like its knocking plus the oil definitely had metal in it, pull the sump off and check the bearings

I made those wraps, banging 👌

Loving the content guys always smashing it out the park !! It’s a shame you build a nice motor but came to this you’ll get it done mate, I think you should get the cupra out of hiding and do some content 😊

21:03 Big up the long reset🔥

Would be ace to see the Cupra finished like the Compact and Passat, thats the car that got me into your channel! Please please dont give up on the V8 tho, these videos are giving me loads of inspiration to persevere with my own engine swap 😅

Good job on the swap wish it wasn't such an arss for you. Would love to see some of the seat Leon.

defender revamp for summer time activities!

Defender next, i wanna see some off roading in that bad boiii 🙂

check compression on it when its warm with oil and without it, check if the PCV is working correctly, you can also replace the valve seals.

Get Andy in an old Disco and hit some lanes. Summer camping with the boys. 2 rigs are better than 1

Any oil on the exhaust being burnt off maybe from that rocker leak? Obviously check all spark plugs see what condition they’re in, check to see if coolant is getting anywhere it shouldn’t too, love the channel lads and what a series this has been so far 👌🏻

4:32 sounded like it was knocking fairly bad

I reckon seeing you mess around with an old mazda or summit similar would be jokes but love the cupra too

SMOKINNNNN 🤣🤙🏻

Great video, even though it was a bit shit for you. Love the look and sound of this hog. Please get the E36 sorted before moving onto the defender next. Ciao

I don’t want to see a new project until the E36 is done completely!! I am doing the same project but with a M62 with a N62 oil pump and pan in my E36

I know you really wanted a v8, but an m50b25 straight swap, k64 turbo manifold, turbo etc and you would have been at a nice 400/450 bhp 🙈. Similar to Jimmys setup in his e36 touring

Let’s have a come dine with me. Love the cooking bits!

Yep. Run a compression test. I can’t explain why power would be up after a PCV swap. It might have been placebo. The OSV behind the timing chains (feeds the PCV system) can also fail and load up the intake.

Colin the Cupra needs some love! Also, Naan bread pizzas go hard, perfect unit lunch!

More defender vids. First should be cleaning it 😂

Buzzing for another video! New car would be awesome!

Favorite cooking channel for sure

Blocked breather building pressure? Would love to see some Defender stuff!

Been theyre sinds i bought my car , 323 1998 , i think every bmw from that era engine had it , only way tht works is to get a catchcan or build something to lat the air escape and the oil get back into the engine . ive tried 2x with new pcvs , first it blew up full of oil in the engine , and last year it just f up my main sensors (crank,camshaft sensor) so basically vent it to atmospheric because it has crazy blowbye or just put new piston rings maybe in it /rebuild

Most the time when you gotta glue on the valve cover it's rings/blow-by. Too thin oil(fuel from blow-by) is not good for bearings. Sometimes thicker oil helps/prevents, did once for me(was rings) but also you gotta change it more often then to keep it thick enough. If you're super lucky, a good oil flush will unstick the rings, if they are stuck.... Flush is basically a last ditch, before pulling it try at that point. I wouldn't think it was just valve seals but it's possible since the pvc thing helped and intake was clearly full of oil. There could be multiple oil sources??? I normally delete any pvc and open vent my performance engines, to avoid sucking in oil anyway. Oil is like anti-octane, hence power loss, so there is hope you could make it ok-ish. If you still get tons of smoke from a open breather catch can, then it's not pvc anything or likely the valve seals. The knocking sound is concerning tho...

Defender series all the way!

Love the e36 videos. Next vid would be fun to watch you guys buying new car.

I have an m62 they have an oil separator inside the timing cover where the timing chain is. That can also fail. Other than diaphragm you swapped at the end there isn’t anything else to it other than rings, could be sticky rings all carbon’d up, I had it on my e46 was burning 1 litre every 100 miles I put some berrymans b12 chemtool in the piston tops overnight and let it soak, cranked it without the spark plugs in let all the remaining gunk fly out the spark plug hole which is a must cos u don’t wanna put the plugs back in then hydro lock your engine when you start it up. Then any liquid that seeped past the rings into the crankcase you want to leave there for the initial startup and idle and leave in there idling for about 5 minutes no longer cos it’s thinner than water and knacker you bearings big time if either left in there for ages or driving under load with it in. But leaving it in there for about 5 mins acts as a sort of detergent to the whole inside of your engine after curing the sticky rings. I had no oil consumption after that.

The BBQ 🍗 looks amazing 😻 ❤

Dont worry nothing wrong seems like the breather is dirty/stuck. For the low power check the engine fault codes it runs on 7 cilinders sounds like it. Can be doddgy cam sensor,crank and maf

Think you’re still far away from finishing the E36 unfortunately, good for us though I love this series. I think we need a defender video, a Cupra video (or miniseries), then a new car and new series. Keep it coming boys

You don't need a graphic designer, you need an engine builder 🥹

Crack on with thd cupra! Keep it up boys!

Came for the cars stayed for the cooking lol 👌🏻 also adventure in the defender or new project car

A video on the Cupra would be great 👍🏻 I bought a Leon FR MK2 just cos I’ve watched so many of your vids on Colin 😂

the only thing I can think of is maybe the oil control rings on the pistons, might be letting some oil through, would make sense as its at higher revs.

Would be good to see you guys go rallying or even trials in a banger 🤘

new build would be bangin'!

The best gasket is hondabond this stuff is crazy i used it on my ktm and my bmw to secure the half moon on the rocker cover it is not leaking

I love the colour of the E36 and also i love that Seat Leon the best Seat ever in my mind

Check crankcase breather boq, if clogged or incorrectly fitted, it will cause all of these symptoms, also not being able to hit rev limiter is a concern. It might be worth having the bottom end off her. Also remember you've changed sump, so dipstick may not be accurate.

I'd like to see a new car build or a breakdown of plans for your others, either way ill be watching and enjoying 😊

Love these vids. That oil didn’t look good 😔. Also got to get a new project car 😎

I reckon you get to work on the cupra again. Would love to see a vid of you and the boys do the nurburgring too

“It’s a bit slow😳” 😂

Something new different silly and or fun, hope ya get the bmw sorted sharpish tho more for ya own sanity than views lol good luck mate

Loving the build but I think a new car is called for once you're happy with the beamer👌

Nice video

Defender or new car I would say maybe new car cause defender is literally so perfect anyway! 👌 good job guys!!

I thought valve stem seal until i saw the metal in the oil. Definitely hear knocking at the start of the video would definitely not have been driving it. Engine not in good shape now regardless 😔. Such a wicked build I would dream of having an e36 that clean. Hope you can get another engine for it.

regardless of outcome the video was lit as always 😎

Buy my cheap swb shogun 3.2 turbo needs welding but I’ve got a full poly bush kit going with it 🤘🏼😂 an off-roader you won’t mind thrashing about

Compression check first thing. If that's all good then the rest of the pcv system

Deffo the cupra, such a sick car!

As someone who cooks in other peoples houses occasionally, get yourself any mug, flip it upside down and use it as a whetstone. Great for putting a quick and dirty edge of a blunt knife!
