YOU SIR ARE A TRUE PROFESSIONAL. YOUR VIDEOS ARE CLEAR, PRECISE, AND EXTREMELY KNOWLEDGEABLE. IT IS A PLEASURE TO WATCH AND LEARN.

I have a c15 acert with 1.3 million on it runs great , uses 2 gallons of 15/40 syn blend in 25000 miles . I have the money to build it , but I hate to touch it .

There's a truck at work that was eating 8 gallons of oil per day. It had broken rings on I think 3 cylinders

when the Pistons are so worn out that they're swapping holes

Most shops would do it just for the money. I appreciate your honesty.

Started my first inframe on a 6nz c15. Have used several of your videos for help. Thank you!

A lot of questions were answered, sure helps me as a young Generation getting into Diesel .. Thanks

Thank you sir for the good info. I got c-15 2009 been having the oil pressure low and I changed but still low

very much enjoy your vids. you come across as an honest and genuinely helpful dude. thanks

Thank you 🙏🏻 for sharing your knowledge !

Mine is consuming like a gallon of oil every 2k miles,now I'm savings some money for A rebuild. Great info!

Love your videos man. Very informative. Loads of useful points

Spent all day clearing snow out from cabins and lodge.. and made sure to clean off my sattelite internet dish just so I could watch this video.

Thanks bro I love your videos. They all are very educational. The way you explain is so great. You need to be a teacher. 💯

Very good video, great amount of knowledgeable information !! Great to see a Mechanic who likes to think too. Thanks 👍🏽

Now this makes me rethink if the shop I used convinced me to get a rebuild and I didn’t actually need it

That’s informative and very helpful , thank you for the video

i like how you explained engine. because i have issued. i did test on cylinder but #6 is low pressure. now the mecinaic say i most have rebuild

Thanks for sharing your great knowledge

So, if it isn't broke, don't fix it.

Thank you for the incredible information. I will go so much further because of you.

Interesting how oil consumption changes when a truck goes from Over Highway use where speed, distance is the key, to being used on farm where it's under high loads, low speeds on soft roads, low speeds in softer fields where it can take all of the 400 HP to get out at 15mph.

Cool! Thanks, i was getting ready to rebuild my 3406 due to high miles but i am jus gonna wait til something breaks :D.. still pulling strong! :)

I appreciate your videos and am working on watching all of them. If you ever do anything on Detroit's please share!:)

Your video's are a great help.im learning a lot. I have a c12 that's in question. Still runs great.But has developed some extra blow by. But I'm thinking it needs valve seals.

In the market for a used 3/4 or 1ton pickup diesel. Good Stuff, Great Help, Good Tips 👍Thanks!

Gets up, first video is from Adept Ape......Cheers, Josh..

I recently completed an “in frame” (Pistons, rings, rod and main bearings and injectors) on my 95 Dodge Cummins 5.9 at 335k miles. The reasons I rebuilt were three fold. 1) Blowby from the crank case breather had become excessive to the point of coming out from under the truck and being visible around the front fenders and hood. 2) It would smoke when started at 90 degrees ambient temperature as bad as it had at 0 degrees when I first bought it. This smoking would only stop when the truck was hot and cruising but would return almost as soon as the engine was at idle. 3) It was running/idling/starting rougher than was normal. When I got into the engine I found piston rings worn so badly that the end gap, which should have been .017”-027”, was between 3/16” and 1/4”! I was honestly surprised the engine was still running with what must have been terribly low compression. The cylinders were still round and were honed to remove the glazing before replacing pistons. (They could probably have been re-used but I didn’t want to risk anything) The bearings showed heavy, even wear but were not “damaged”. Rod and main journals were still pristine. Following the rebuild there is very little blowby, no smoke beyond the quick puff when it is started and runs smoother than the day I brought it home. I feel like by rebuilding when I did, I avoided the rings becoming so worn the pistons could have scored the cylinder walls. This video helped me pull the trigger on the “in frame”. Great expert, real world, advice.

you should have your own channel on tv. great work

Awesome video adept ape!! With what you said about blow by, does it count for a 7.3 idi?

I love the videos, so much to learn!👍🤜🤛✌

If your replacing liner seals you should go ahead and do ring rods mains and new liners.reasoning for this to me is the fact that the most expensive part of shop work is labor. At 120+dollars an hour if there pulling sleeves youl save money in the long run to get the pistons and all other rebuild parts replaced.

good video, well spoken, helpful, thanks BXS

Nice video, was worth watching.

Great video, thank you.

very good info. I have a m11 with what i feel is alot of blow by. but after seeing this i think im good for many more miles

Great video as always

Nice video ! I work at a kenworth dealer we don't see those cats anymore lol ! Nothing but Cummings and paccars. Great video tho !

My Cummins Big cam 400 started pushing water out of the overflow tube on top of the radiator. Lots of bubbles when I took the cap off while it was running. Head gasket? After finally taking it apart I found bad head gasket and a cracked piston where it had been leaking water. Bummer. Honestly if the truck wasn’t pushing water out I would never had known because the truck still ran perfectly. Now I get to learn how to fix it.

awesome man thanks

Good explanation. Just subbed

I dream of being an owner / operator and you being my dedicated engine man. Great video again!

Love the channel bro!

Your dam start ,to do all this in one take and not have to think about any of it..luv your content

I have an old gm 5.7 olds diesel in a Cadillac Seville. Failed emissions at 60% opacity. Changed injectors and rebuilt pump. Cleaned fuel system from engine to tail. Anything else I should look for before I try again? It's been off the road for 6 years while I fix other stuff too. So when I go to crank again should I remove the glow plugs to bring the oil back in the system before firing it up again?

Awesome Video!🎥

Adept Ape , Absolutely The Best Explanations of Diesel Engines of anybody on the Internet and or anywhere else I have Found, Thank You For Your Expert Wisdom. I have Been A Mechanic All my Life more so as a Side Line but have been involved in Many things, Have even Been A Truck Driver when ever I needed to Fall Back on something from Time to Time But Also am Very Close to A Million Miles on that to. I am Per say Retired Now and looking at Motor Homes, I have Had Gas Motor Homes Before and am Now looking at a Diesel. I am looking at a 2005 Diesel MH with 90k Miles What would You Check on the Engine to Try and Determine its State of Condition or Ware, I have my List and I want to Know If I am Or Will be in the Same Ball Park as you would Be if you were Buying it. I have been told the One I am Looking At Does have a Service Record on the Engine. At This Time I do not Know what engine it Has But it is 350 HP and is a Cummings or a Cat. Thanks for your Input and your Absolutely Great Videos. God Bless America and Its Disabled Veterans.

Thanks bro, was really worried after seeing blow by in my engine...

I generally find I have to rebuild mine when my brother in law has borrowed it and then worked a vintage tractor so hard one of the rods is sticking out of the fuel pump. I can diagnose that rebuild wihtout measuring equipment. (Just angry rant is all)

Nice video, I have a 2.5 tci diesel engine and it has a blowby, but is not consuming oil, the engine has lots of power, my mechanic tells me that the ingine needs a rebuild, but beside the blowby, the engine runs jus fine

I am taking over my dads truck and it’s been sitting for a minute and want to get one just to start fresh

I like all your videos. They are educational. Question for you. I have a f250 6.9 idi natural aspiration, non turbo year 1985. The diafram on the cdr is broken an I found some oil in the air filter compartment. Can I turn a new cdr valve a 180 degrees and plug the hole in the intake and put a hose from the new cdr to a oil cath can and then another hose to another oil cath can and do not reconnect it to the intake? Or what do you think is my best option? Right now with a bad cdr is smoking but if I desconect it the smog stop by I can see blow by. Thanks one more time for your videos.👍👍👍

So do you suggest to run to failure? We don't like that especially on marine engines. One question about 3512 longevity do you have experience with this motor?

Thanks man

I rebuilt a 1,9 TDI 1Z from 1996 after nearly 400k km. But it needed a rebuild badly: - at least one broken/clogged injector, ran on 3 out of 4 cylinders. - head gasket already leaking - much other small stuff which was replaced since the engine was taken completely apart runs now just fine again and hopefully another 100-400k km

I'd like to get a 3406b but I'm stuck with a ntc300 cummapart has had an inframe done ??? But I found a thrust bearing in oil pan and #6 camshaft injector lob is got some marks on it, I fixed the bearings runs like a cummins. Think the cam will last awhile? Don't use it much just to move an excavator

I got a maxxforce7 international I got excessive amount of white smoke I can't drive it because of it, at first I was loosing coolant but now I don't (I threw head gasket sealer liquids) I replaced the water pump cus it was bad, I changed the turbo and egr but still the same problem, I pulled the dipstick out and muddy oil came out of it, I have a strong blow by even from the dipstick the truck turns on and runs fine but the white smoke is insane only when running

Hey big J! For the guys that need or want a complete engine overhaul, Wouldn't it be better to install a complete rebuilt engine instead of doing a complete In frame overhaul? Wouldn't it take less time to do that instead and come with a better warranty? I just want to give a huge thanks to you for giving back to the craft. Not a lot of guys out there willing to give back in order for others to become better at what they do .

Question On Cummins 8.3, I took it in for a skip with no check engine light on. Currently have my RV at the Cummins dealer, they said it dropped a lifter and needs a rebuild. That was after they replaced the injection Pump, Lift Pump and #3 Injector all at $9k now being told that I need a rebuild for $14k and they will eat $3k for the cost. Wondering why they did not check the compression at the start instead of putting on all these parts. They also said I might need a turbo if it's damaged from any metal in the system.

@Adept Ape I have a mercedes om606 with a problem; upon startup it blows a lot of white smoke. it goes away after its warmed up but if you stomp on it you can sometimes still create the issue. engine code showed glow plugs. i have the engine apart so i can't do more diagnostics right now. do i need to rebuild the whole shabang? thank you, chris

Small 60hp David brown tractor uk I spun a bearing but iam not going ti rebuild, just going to use emery cloth on the crank and hope for the best, what'd the worst that could happen throw a rod through the side?

Thank you sir. I had that question if to rebuild or not. No major issues just 1400000. Doesn’t really burn oil 2 gallons every 14k miles. I have a C-15 Accert. 2005. No problems with my engine love my Accert. It’s a money-making machine. Thanks

Great info

I'm about to have the head on one of my boats CAT 3208T's due to (I think) a coolant hose failing, and subsequently finding out the temp alarm was in-op. Water in the oil. I'm hiring a proffessional mechanic to do the job. Are there any wear items you would recommend addressing while the head is off? The engines are 35 years old, and have 3500 hours on them, and I do not have detailed service records to reference. Thanks for the great videos!

Great video 👍🏽

Thanks

What about if truck runs good and doesent get hot but it pushes coolant out of the overflow tubeand have combustion in coolant

Do you have any videos showing you diagnosing the cause of blow by and repairing it

Have you heard of any negative feedback from the remanufactured ford motors. I’m looking for one for my 7.3 L. I was pricing everything out and it’s definitely a lot cheaper for the amount of work I need. But I don’t know if it’s lesser quality when it’s titled remanufactured

Is the bump up on the cruise control meant for idling at higher RPMs?

Hey I'm all the way out in Jamaica and I have an 93 Isuzu npr that has the 4bd2t engine in it but it dragged piston last December should I rebuild or change it?...I've already done it twice before and it still has in the factory sleeves

I have an old Cummins big cam ntc350 started smoking a lot even at idle it would not clear up and had disel going into the oil , took it apart and found an injector with a broken needle so I put all of them new and ran the overhead , the smoking kept going but it did ran with a lot more power but when I checked the oil it keeps getting disel in there , what’s ur opinion is a rebuild worth it any ideas I’m trying to figure out what to do and fairly new in this

I got a 3 cylinder diesel ford tractor that needs a rebuild but she still runs good could use compression rings

If your considering a rebuild,would you recommend a reman motor,for an 05 cat c-15?would that be less expensive route than in frame?had friend spend 25000.00 on inframe .

I have a Detroit 12.7 with a bad head gasket leaking oil like crazy it’s about to hit the one million mark so I just go ahead and overhaul or just do the head gasket?

Can you talk about damper plate replacement on Ford Lehman marine engines? My engines vibrate a lot when at idle. They have 6500 hours on them.

I have a 3406e 5ek and the oil pressure is running at 50psi when engine is hot and at 1500rpm. I'm thinking that's a little low, what could be the issue? Engine has 1.1million km and 24k hrs. However blow-by (engine hot) is surprisingly low for those particular engines which says the engine is far from worn-out, so what could cause the low oil pressure? Any suggestions would be appreciated.

I have cummins isx 15 my truck in pete 386 2013. I have had radiator and water pump replaced recently and now after that I have coolant leaking I dont know the reason any guess by you?

I currently own a pet project that was our main delivery truck for the last 300,000 Km. It’s a Toyota HiAce, a light truck with a 2,400 cc indirect injection Diesel engine called the 2L. It is currently at 450,000 Km. As soon as 150,000 Km cold starting produced rough idling and the emission of pungent blue smoke which subsides soon after the engine fast idles by holding the gas pedal at 1/3 throttle and it warms up. Therefore, an intake valve is probably leaking. The procedure for cold start per the owners manual calls for holding the gas pedal at 1/2 throttle - preheat - start the engine and then to gradually release the gas pedal, usually yields no issues. However, if by any chance you start the engine without holding a fast idle, the pungent smoke and a cylinder missing occurs. Is this the swan song for this engine? I have been using the most modern motor oil available, API CK-4 SAE 15W/40 in tropical conditions year around and change the oil (6 liters) and the filter every 3,000 Kilometers thus, there is no oil consumption whatsoever. I haven’t done the crankcase blow by test yet. Any comments will be highly appreciated and cheers from Costa Rica!

So how do you go about messuring the blow by on cats does it have a sensor or something

I can't see not installing new power packs if you're already taking them out to replace the o-rings. It just seems like a wasted opportunity. Also time and more along with more down time when it finally has to have a rebuild

Boss is the life of seals in diesel engine, we have Detroit 16v149series( TIB) done 2500hrs since 1990 .we never rebuild completely yet, what's the life approx in hrs or years and also seals life too?

I have a 2008 Hino and it's leaking coolant from the head gasket 😑 I been running it like that for a while. can it get worse!? or should I fix it?

I have a lot of roast particles lots I'm my dohc isx what should I be looking at to fix or is something really wrong

I like your videos. thanks for share great information. My question for you is the next:. I have a f250 6.9 lt. I noticed some blue smoke when accelerate. the DCR valve is not good . I removed this one and blue smoke stop by I observed the. flow by. do you recommend to replace or just cancel it with a hose to the chassis area?

What’s is the difference between rebuild or overhaul ?

Excellent tuition as always, you should consider teaching as you keep it simple and interesting. 😁

Black smoke can be intercooler in manifold blocked.

Thanks!!!!!!!!!!!!!

We found alot a metal shaving on oil pan.. My mechanic said rebuild..so 13k later idk made the right choice..s60 480k miles

Have a Cummins lots of blue smoke but not using oil watcha think

When the compression is leaking enough past the rings that the engine won't start cold, it's time for a rebuild!

I love this guy

Need help,,, I have a C15 when the check engine light comes on I lose power but when I turn the engine off and then back on the check engine Light disappears so is hard to get a diagnostic because there's no check engine Light no more

I have 2005 mxs cat c 15 acert twin turbo has about 855000 miles and 8635 hrs on and when it has gotten about 5000 miles on a new oil change it starts throw more blow by and if its hot it also has more blow by and burns more oil then normal if drive it over 15 rpm or faster and is it ok for them to go over 80 mph ?

Can you make something on Stop Leak on a CAT?? People say it works and might give me at least another month or two before I should do an inframe!

I'm contemplating a repower of a 1990 45 foot flybridge Post.. Right now it has the detroit 6V-71 'fuel pincher' (yeah right! compared to what!?) turbo diesels. And I want to get my economy up. Right now a duo of Cummins 5.9 12 valves are looking a pretty serious contender. What are the 24 valve 5.9's like? I like that they are pre DEF and pre DPF, but turn a really nice output in marine trim.. are they worth the extra complexity though?? They will be cooled by heat exchangers btw, I'm not having any raw salt water going thru my expensive engine blocks and manifolds! I'm wondering who to trust to obtain the engines for the repower? I know that the engines have to have different, marine bowl pistons fitted and run more boost than in truck / bus trim. I just want to know what the longevity of the 5.9 QSB engines are? Cheers

fun videos. Have learned about my 3126 from watching. Can you talk about the old mechanical 3406 engines sometime. Some say they are as good as the electronic engines.

Great video. I have a question should you have the overhead ran every year

How bout when you have to ether it when it's 100degrees in the shade?
