They forgot the worst way this could fail.

I had a run away diesel once, that was scary for the first time 😅 quick thinking I just put it in 5th and slowed down till it stalled. Thank God it was a manual
This is incomplete. Seals on the hot side (turbine) can also fail, allowing oil to enter the exhaust side where it is atomised by high EGT but not burned due to the lack of oxygen. It results in a grayish smoke with a characteristic oil smell (it's different than burnt oil smell, and the smoke isn't white as in the case of coolant entering the cylinders).
@@mreasy4581 well, that could happen - overpressure caused by a blocked exhaust after turbo (like blocked DPF) will likely cause the turbo seals to fail in some manner. Turbos are fun and effective, but unfortunately they alone and their associated hardware are quite fragile and may cause not-so-fun failures. I've had a different problem in a petrol engine - blown oil pan seal. The one-way valve on the PCV failed and let the compressed air go into the crankcase, which combined with 220kph on the highway caused unnoticed loss of oil within the next 100km and finally a spun bearing. It was quite an interesting experience - the sound that engine makes when this happens at 90kph and around 2,5krpm is literally like in old-school games, as if you'd throw some metal tools into a steel bucket. :D
My YANMAR 4jh3-DTE in my boat looses oil. There is no smoke. It can loose 1 liter oil in 2 houers use. I have checked the oil-cooler with 8 bar on the oil side...no leaks. I wonder about the Turbo ... the exos go direct into seawater after turbo . What do you think? i think it looses oil faster on high rpm .
The extra oil in your combustion chambers also suffocate the octane levels in the fuel thus increasing the chances of detonation... Potentially destroying a performance engine
Well not necessarily as engine oil itself has a very high selfignition temperature which is close to that of petrol. Much worse is diesel in petrol. Even very little amounts will reduce the octane rating significantly and same goes with lubricating properties of diesel with petrol in it
A catalytic converter is a part of a vehicles exhaust system that helps to burn off any of the unburned air and fuel that leaves the engine so your not just dumping raw gasoline into the air. Its for emissions
Просто повреждение катализатора или загрязнение сажевого фильтра - самое безобидное, что может случиться. Страшно - когда утечки масла достаточно для работы двигателя. Тогда он уходит в разнос и остановить его будет проблематично. Нужно или перекрыть воздух (заткнуть впуск, можно использовать CO2 огнетушитель - он вытеснит кислород), или перегрузить сам двигатель (повышенная передача и отпустить сцепление, удерживая тормоза)
Turbo can but usually do not fail from worn seal . The seals are metal just like the ones on your pitons. Blow by and crimped , crooked , blocked drain causes leaks.
@@MrWaheedulHaque better replace turbo for a new one, if you refurbish your turbo they will replace your heart of turbo with chinese parts and you will need to refurbish it again for a year when warranty expires. Sorry for bad english, best turbos which i had experience with is BorgWarner. I hope that i helped you.
A turbo is supposed to live as long as the engine if well treated.... Never go above 2k rpm when it's cold change your oil regularly and never immediately turn off the engine after a hard pull or the turbo parts will keep spinning but the oil won't circulate in the system causing turbo failure due to lack of lubrication
@@relayfree1273 You don't turn the engine off after hard driving because it will cook the oil, the turbo will stop spinning like in 3 seconds after you turn off the car from idle.

The reason why we want to use this video is to explain what happens when other substances, not oil, enter the car engine. I hope you give me permission. Of course, I will expose your RUclips channel name in the video. I would appreciate it if you would give me permission. Please reply. Sincerely, JTBC.
They only talk about damage to the least important component on the engine. Delete that cat, rebuild that turbo, and get on with life. The BAD thing that can happen here (with a diesel) is that it can run away on ya if the oil leak is severe enough to power the engine on oil alone. (a diesel can burn almost anything, unlike a gasoline/petrol engine) If this happens, and you're unable to choke or physically stop the engine, it will violently destroy itself. Sad thing to watch!

I still found the engine oil on the left side of the car and at the bottom in the air hose that connects the turbo radiator please the turbo - is it broken and spewing oil through the air hose or what? Thank you in advance for the reply
Can bad seals in turbo cause a puff of rather white smoke when gas pedal is released? There is no smoke when accelerating. Only when deceleraring after hard and long acceleration. I cant see any oil nor antifreeze level drop
I have a 2009 model Ford Fiesta diesel. I found oil on the compressor side of the turbo, but the turbo shaft has no play( no wear on the shaft). One mechanic said its because of the back compression in the eng cylinders and some rings may be faulty. Also compression test says all cylinders compression is normal. so what might have caused the oil on compressor side of Turbo
It can be changed. You have to have the turbo rebuilt to do it. If you want to see that, look at the Area Diesel Service channel and their turbo rebuild videos.
That's one reason I wouldn't use a turbo Turbo suck they have trouble with their keeping their rings from going bad and they're impellers from getting damaged and wobble around losing even more power so I'll stick with a blower motor I'm going to do anything like that

On a diesel this is a death sentence. A colleague of mine had a 3.0L V6 TDI with the turbo that failed and the oil went in, it ran away and detonated

@@TheEgozcuea replace the turbo dude before it is too late
if turbo was missing oil pressure for a long time (5-10min) would only the brass bearings get worn out or the shaft as well?
Turbo in old car start leaking engine oil a little bit .
Often intake hose is oily.
It's just acceptable no need to worry much .
