Hi forum... Long time since my last post here....well... I´ve noticed this oil leak in my turbo, my engine doesn´t have oil consumption and doesn´t smoke too. Just sometimes in the start. My turbo works since 2000 RPM, and the Turbo lag ended at 1800 RPM. what it can be ??.....check the pic below.  Ok...c ya Dani |

That pipe at the top is the oil feed and the elliptical flange at the bottom is the oil discharge for the unit. If you unbolt the top one there are two washers that create a seal on that pipe end to the turbo unit. Check/or replace those to start with and see if that solves your problem. You can leave the motor till it's cold and safely undo that top bolt with out much spillage. J

I'm more inclined to blame the rocker cover breather.My worn out rattly 96 Rodeo motor leaked a heap of oil from the same area.Have you done the oil trap mod to your breather?

I agree with the rocker cover oil feed pipe which goes back to the turbo, I had the same problem after putting a oil based air filter in the snorkel, which then made two, was told that oil filters are not good for turboed engines, anyway that another story, so what I was advised to do was put a oil colecting container in the oil line between the turbo and rocker cover. I unscrew and empty the oil when I do the 5k oil change and no more leaking at the turbo.
I do not run the Unfilter any more, but use a paper filter which I buy for $22 in Rockhampton.
Cheers Bruce

Its a long time since Ive seen a motor as clean as that. I would be inclined to leave it alone but still check it every now and then in case it gets worse. A tiny amount of oil can go an amassing distance. My engine looks like oil is pouring out of it but it never needs topping up between changes.

From your pic it does look a little damp from the top oil feed line. There are two copper washers that are used for seals (one at top of bolt and the other between turbo housing and inlet pipe face), these deform when tighening. I replaced mine with new ones when I replaced the turbo.
A common problem is the turbo leaking internally as others have said before. I have had the rocker cover breather problem of passing oil back thru the turbo, so I also installed an oil catch and drain system which works very well.

hey dani! i was to get some time off sometime last week and yes, i was also able to tinker with the oil catch thingy since i found something i can use from the hardware car section store...well its actually a fuel filter for cars...but it had what i needed, a container with a filter inside and a T connection on top but no drain...i have yet to see if it will work...been using it for 2 days now and for sure there's less smoke...will see how much oil it will catch!

sounds good mate...please post a pic !!!
a few days ago, i took out the pipes from the turbo to the intake manifold. I found them very very dirty. There are burned oil in everywhere inside. I tried to clean the most possible, but it wasn`t enough. I have to take them out once again and do a deep clean work in all the interiors. Whatever, the little burned oil i cleaned last day it works for get less smoke from the exhaust pipe.
cheers

 hi dani, dunno if this one will work but anyway, here's how mine look like! to all those guys who did the oil catch mod, do tell me if there's any disadvantage to this my only worry is, i got a smaller hose to fit those T connector and then it plugged right through the bigger hose...wouldn't this act as a bottle neck for air passage? though i removed one end and i can feel a little air coming out of it so the engine must be breathing through it... |

i also forgot to tell you that my turbo gets wet on the other side (just on the other side, opposite the area where your turbo is wet...whew! the best way i can describe it! not the one directly connected to the air duct.

Might need a picture to see exactly where you mean This could be the gasket or one of the oil or water lines ore a seal or somthing else. In the past when tryuing to find messy leaks the best trick has been give everything a good clean then go for a short drive then have a look to see where the wetness stars from. Unfortuanatly the last time I used that trick it was on a Hilman Avenger that has slightly more room around the engine. Your catch can should work ok but the inlet and outlet are quite small This will be ok if the engines good but if it makes a lot of blowby it could blow apart or presurise the sump

which will blow apart? the connection between the catch can? or the engine? pardon for my ignorance!=)
and when you say pressurize the sump? what do you exactly mean? pressurize the crank case?
will the small opening be bad for the engine itself? well, i made sure air is passing pretty well through the can, and i checked to see how much oil the can has after a week of use and it barely has oild inside it. hmm..now im thinking of getting a new hose and get rid of the catch can!

...and won't the outlet which connects to the intake tube help lessen the pressure since its sucking the air as well?

Unlike most petrol engines air dosnt flow though the crankcase This pipe is only to vent blowby that excapes past the rings. If you restrict this flow then pressure can build up in the crankcase although the motor would be quite tired by then This can cause various engine leaks etc The filter you used would blow apart before any real damage to the engine and since you havnt clamped the pipes they would blow off first anyway.

i didn't have to clamp it because the connection was pretty tight already. now i couldn't even take it off! ok then, will observe further...i might also try to just attach a breather filter instead of the oil catch since blow by oil isnt that much for the filter to push back the excess oil to the crank case! other diesel users found it to be more effective and i don'thave to worry about breathing probs
