Cracked Turbo Housing Symptoms

[Ahmend Studioz]

Oklet move on to the turbine seals. Now, there are a few different types of seals for the turbine shaft. Most popular is a single gap steel piston ring. Works great has been for years. Things that it does not like, high crank case pressure, low perched turbos, too much oil pressure. How many of these will blow out that seal???? NONE!!! Next seal is the gapless ring. You can do this two ways. Run a piston ring with a labyrinth lock for the gap. Or you can stack 2 rings back to back then offset the two gaps. This is very popular in the Porsche cars. A lot of those cars run 6 bar of oil pressure, low turbos, and sump pumps. For a true seal, the best set-up is two gapless rings in separate grooves. This will seal very well. There is a down side though. By the time you notice its leaking there is not much hope for a cheap rebuild.

Hi mate ive got a turbo diesel landcruiser. I was towing my trailer and noticed a big cloud of white smoke from the exhaust. On inspection i noticed the pcv hose was kinked. So obviously I sorted that out and have not had any smoke since. But what i want to know is will that cause the seals to fail straight away or could the excess pressure have pushed oil past the seal without damaging the seal. So no oil can get beyond the seal when normal crankcase pressure is present.

I have a International 175 track loader. The outer exhaust manifold cracked and blew hot gasses on the trubo return line and turbo itself. The turbo is now dripping oil out. If the shaft runout and endplay is acceptable with no damage to the turbine wheel, can I buy a seal kit for it? Thank you

A seal kit rarely will fix the problem. If your bearing are going out, that is usually the oil consumption. The seals sit in one place. If the shaft is in contact with the seals it can wear them out. For example the bearings having to much slop in them. But, you did say the exhaust leak burnt you return line. I would fix that problem first. If the return line has any kind of back up the turbo will leak. Even with good seals.

Those turbos and intake get really clogged up with sticky carbon. Its from the EGR dumping right in to the intake. This can cause all kinds of problems. check all the intake tubes and oil return line. See if you can blow down the turbo return line. The turbo could also be stuck in a certain vane position. Those do have some actuator problems. If your PCV lines are not right it will feed back through the oil return line.

It could be both. Easy to test though. Check it with a leak down tester or compression gauge. Or you can take it to a shop and ask them to do a coolant sniffer test( it a chemical test). It will pick up hydrocarbons in your coolant if you have a blown head gasket.

The TDI cars have a lot of problems with the EGR dumping gum in the intake. This can cause thrust failure to the turbocharger. Also the vane can get jammed up from carbon deposits. This can causing a chain reaction to the heave sticky oil problems.

I just put a cartrige kit in my turbo (hx35 ) on a 1997 6bt cummins. Ran it on the stand for about two hours and pulled the intake/compressor housing off to re clock and paint to find a film of engine oil around the face of the turbo. Should I be concerned?

I recently caught my turbo leaking excessively. It ran fine before the engine build. I found the return line pinched. After removing the turbo there was quite a bit of oil in the exhaust header. Being I fixed the return line, what are the odds themail damage is more extensive due to the amount of oil in the exhaust header?

I have a 2010 focus 92000 miles on the clock. Regularly serviced. Its running a bit sluggish. Garage told me the turbo is leaking. They plugged her in to check reason why she is running sluggish nothing else found. How long will she run with a leaking turbo? How has this just happened n not been picked up before? Do you think I should get a second apinion. Regards Josie Barrett Mrs

hi , i have probelm with my cruze 2.0 vcdi , the turbocharger leak oil & engine gets high temperature at normal speed & white exhause smoke , is it failure of head gasket ??? beCaUse whEn m deaL with some engine head works earlier have been reused the old head gasket .!

My Turbo leaks between the core and the exhaust housing when the car is stationary and after 2 days, i noticed the turbo was missing one bolt on the exhaust housing, could that be the reason why oil is seeping thru?.

Im not sure if my turbo system is going bad. But my 2013 escape makes a awful noise when ya gas it up. Almost sounds like sonething is scapping together. This mornibg i got a smell of a little oil while driving. The only smell has only accured once before since the problem started.if it sounds like a turbo please let me know i hate to drop money into that if its not the actual problem.

I have a 2007 mazda CX7 i am loosing oil somewhere, i do not have a cloud of smoke coming from the car. I have remove the exhaust and was expecting to see oil blowing out.

I do have a lot of carbon in the exhaust.

After i drive awhile i have oil splater spots on the rear of the car.

Hi I have a audi a4 2007 when I pull away and as the turbo kicks in clouds of white smoke come out the exhaust and av noticed the oil has dropped to half I filled it up about 6 weeks ago I had the turbo replaced September last year and it was doing a similar thing before it went before could this be the same problem and if so could there be a cause for this happening again also the car has a horrible smell

You probably have a turbo going out. The oil pressure goes up and fills the turbo. That will cause the smoke. But, when the boost and turbine pressure rise, it can hold the oil back in the turbo. Do the smoke get really bad when you let on the gas?

I have 3010 srt8 ( Chrysler 300) built 6.1 twin turbo. Ran fine. 870rwhp. @ 15 lbs. spooled up very well. Now one turbo is leaking slot of oil out compressor side. Spools very slowly and will barley each 14 lbs. nothing has changed other than the oil leak. Turbo still spokes freely by hand, not as well as the other turbo. So is the turbo in need of repair?

I see this a lot on newer twin turbo sets. The turbochargers get usually get placed very low to clear parts. Then they run a scavenger pump for the oil return line. when its not set up properly they end up running restrictors for the oil feed line. The SRT8 engines run very hot ( I have one my self hahe) So the turbo probably has lack of oil flow and burnt up.

Hello Tim

I have a bornwagner kkk variable turbo on an audi q5 2.0 tdi. Engine code CAHA 125kw. Turbo code is 03L145701E. It is a remannufactured turbo from a respectable uk company. It was recently bought after the old one blew due to low oil pressure. Everything was thoroughly cleaned (intercooler pipes egr system) Worked fine until car had injectors sticking open issue and oil contaminated with diesel. Had a treatement with engine oil flush and changed oil and oil filter after changing injectors.

It is leaking oil in the exhaust after the car has warmed up even on idle. Feed and return lines lines are ok. Oil pressure ok. Pcv seems ok. Car runs fine turbo operation is ok, no codes

Is it the turbo or you think of anything else..

Hey there i have mazdaspeed axela, had a smoking issue before and turbo and pcv system was upgraded never had a problem for 3000miles, then smoking occured again, although compression and leak down tests were done no actual faults were established until my brother noticed a crack in the rear housing of the turbo, about an inch long. We cleaned the oil thatd been leaking out this crack with brake cleaner and started it, it backfired alot so we knew the brake clean has made its way through. Any reason oil leaks through that exhaust housing crack? And is it safe to drive it to repair shop if i have sufficiant oil in the sump and no other problems? Thanks.

Hi I have a Mercedes C250 TD 97 model I have a problem with where by I see some oil siting in the inlet manifold but when I checked the air induction pipe from the turbo to the intercooler its wet of oil the vehicle is not smoking and performing well

Hello there i have a question long winded lol i have a Hyundai i800 style 2.5 diesel it is on 103000miles had a split in the inlet manifold side took the pipe off to change it whilst i was there i cleaned out the intercooler there was about 2-3 eggcups of oil in there so i checked the turbo and there was a good pudding spoon size of oil there. Should there be that much oil in the system.. whilst cleaning it i noticed the impeller shaft has forward and backwards movement easy 4-5mm also side ways and up and down about 1-2mm i can hear it spinning when i just turned the engine off.. Also i am getting rough revs and little black smoke on acceleration but it does fade at constant speed. Told you it was long winded lol thankyou.

I have Land cruiser Automatic, the Oil is coming from the turbo horse pipe then connects to the inlet chamber even the inlet also. is it the seal from the turbo causing that problem.The vehicle starts very well but some mechanic are saying the engine is bad needs overhaul advise me that Thanks by Andrew

My question is the leak is coming from the turbo and turbo horse pipe takes oil to the diagram and inlet, which drops oil down to the self starter could it be caused by the turbo seal, should i replace the new turbo

You could have a bad check valve in the PCV system. ( or a bad turbo). But, make sure the check valves are working properly. If you go under boost with a bad check valve you will fill the crank case with pressure. That in return will cause the turbo to leak oil.

A turbocharger, also known as a turbo, is an additional system used by car manufacturers to boost engine power. Turbos are commonly used to deliver the same level of power in smaller cars that's usually found in larger cars.

Almost all manufacturers now offer a turbocharged model in their line-up. It means they can provide smaller engines that produce the same power output while also increasing fuel efficiency. For example, Ford have replaced their old 1.6-litre petrol engine with the new 1.0-litre turbo EcoBoost unit.
