I have a car (Evoque) and it is leaking a small amount of oil (just enough to drip off of the oil return line bolt head) and it is coming from where the cartridge connections to the manifold. This is a stock turbo and has the stock oem oil return line that isn't damaged at all. The compression check on the engine is good and the PVC system appears to be working well. I checked the leak at idle and it shows up after about 10 minutes of idling. I expect it leaks more at higher loads. I have definitely learned from you turbo experts that the problem isn't likely to be the seals in the cartridge. But for the life of me I can't figure out what it could be. The piping going to the charge air cooler has no more than a very slight film of oil in it, which I assume is ok.
I have a turbo on a Saab 9-3 2.0 T 08 not leaking oil but introducing exhaust gases into coolant lines it seems to be the Outlet coolant line that taps into a T on top radiator hose. Head gaskets good it keeps asking for coolant when this is attached when unattached and blocked off seems to drive fine hardly any information on the web about this wondering what does possibly could be the car still has boost drives fine with this hose blocked off it was blocked off when I bought the car I did not realize it been driving it like this for a while brought it to a European specialty garage and they said the inner seal of the turbo was gone they looked at it with a snake camera. Any help would be greatly appreciated
I’ve put a new turbo on new engine and it’s leaking oil out of the exhaust, engine changed due to engine piston rings damaged. There’s a build up of pressure and the dipstick is flying out what is the problem
I wish more people would watch this video. I've boughten Turbo's that were "bad" with blown oil seals and sent the drain fitting back to them saying that this was the problem and that the turbo works and is running/boosting with no problems. I've had most people message me back saying thank you for at least letting me know... the people that are nice about it. I've offered to sell it back at what I bought it for and the people who are assholes I just keep the turbo don't offer it back. I've gotten five or six turbos like that. The very first turbo I ever put on my first turbo car was acquired this way.
Great Video. Thanks for the information. I have a 12.7 Detroit. I have a SXE S480 . What drainage size do u recommend? I was looking into the 10 AN or 12 AN
Amazing explanation , great video , i have an mercedes OM642 diesel engine with the garret turbo , i was chassing an exhaust leak ( nasty diesel smell ) and after doing a soapy watter test around the turbo , sure enaugh i found a leak around the turbo actuator arm in the cartridge , is there a seal in there i could replace ? or does that mean i have to rebuild the unit ? , thank you
i have cummins isx 2010 i had change 3 turbo same day and all are leaking oil finaly i keep that turbo now still leaking oil but is working on it since 2018 October my question is if turbo is bad why is running turbo so long till now
hi mate, in my case, the intake hole is filled with silicon and got a small space through. would it be enough reason to make turbo leakage even though the shaft is perfect? thanks
Are there any possible way for the turbo to leak any oil into coolant/radiator? Have an old 2,5 diesel ranger 2004. And it seems like the head gasket would be fine but it seeps oil from some where? There are no milky foam etc in the oil and the oil in the radiator are more like "sludge". Brown but not foamy
@@johnj0709 , your issue sounds like bad Oil Cooler Seals. When those seals, or called O-ring Seals go bad they let oil into your cooling system. This will be visible by a dark color change from oil seeping past the Oil Cooler seals located in the Oil filter housing. Watch this video. th-cam.com/video/C2C3Y4gWwIY/w-d-xo.html
Seriously? Oil comes out of a turbo looking like foam thus the return is larger than the feed. It dissipates back into liquid as it travels down the return pipe, there is no point putting stock bearings or seals into a worn turbo the unit needs oversizing. Now you claimed in one of your videos regarding oil feeds is to fit the biggest you can, again your wrong every turbo is designed with spec oil flow rate from the manufacture in liters/min also too much oil causes paracitic drag. Please dont give incorrect info and don't mislead people or just say nothing.
specs and manufacture information this can be true based on their testing that can be applied to the designated application only or across the board knowledge one is from a book the other is learned via dealing with issues building and time ...the latter is a open more informed approach to start with for problem solving and building the first is only needed in a race team or oem application fer the most part .the guy is giving novices and silly heads the best over all approach to getter done with what he knows i am glad of it really help me to learn a few things ..only so much oil can flow in the bearing as the hole is small so over feeding type of drag a moot thought in the turbo unless say in a crazy high psi oil pressure situation and may exist in a diesel somewhere and that oil feed would have a regulator on the oil feed outlet i never ran into that but thats be the only way i could see it happening
@@overbuiltautomotive1299 you know the difference between pressure and volume then ? Pressure is nothing but a measurement of restriction and no, manufacturers spec oil flow based on the turbo units needs regardless of application, so misleading a newbie is right? All else fails read the instructions, and i gather you have a understanding of parasitic drag ? Cause lots of pul pressure is great for engine bearings right ? But no you stick with teaching newbies BS cause it does no harm right....oh dear

It’s possible for the rear seal to be worn, watch the video I made of what bad turbo seals look like

A lot of my turbo rebuild veterans say OEM Turbos break down 9 out of 10 times…it’s best to get used turbos with low miles.

If I have oil between the centre housing and the turbine.. at that seam can I assume it’s the internal seal?
Thank you
How about oil catch can leading to intake tube then to turbo...on mini cooper r56...can it cause leak? Tnx
Hi sir u just rebuilt a turbo,now is smoke while i rev2000rpm and smoke on of some time got smoke izzit The problem my drain hole small ?

How about a restricted path inside the oill pan where that drain tube pours into

Love the videos
Thanks Turbo Lab.
Thanks : the turbo is leaking onto the manifold 2013: Jetta tdi sport wagon . Does your video pertain to this engine?
There isn’t enough context for me to know what your issue is.
This or A lot of crank case pressure that is putting pressure on the oil drain line.
This is the truly truth.
my turbo is leaking oil from seal in middle when idled
Thank you
Im leaking oil from the dumpvalve ?
keep them videos coming! i got MMP's stage 3 on E92.
Well said
I’m going to need your help
Hi i just rebuilt my turbo t3 garrett and i have a smoke issue, can it be from the oil that go into the turbo?
And I'm finding oil in front of the turbo outlet.
Does this oil drain problem result in oil in the intercooler and intercooler piping?
Yes

where you located
I have BMW 320I Xdrive 2014 F30 ,it was leaking oil ,they have changed gaskets and pijp, but still i see its wet, and smells when car engine gets warm
I texted you about getting my durramax turbo built
Did he reply?
