hi guys im sure there is a thread about this somewhere but cant find it so if someone could please help me it would b much appreciated... so i was putting my megan o2 housing in the other day and wound up having to take the turbo out, came out fine no problems, changed the o2 housing and put ti all back in, but when i started it up i noticed i had an oil leak, so today i changed the seals and checked all the bolts and they are good, so i have no idea where i can be leaking oil from, i think it might be from the center housing cause i tried to split the turbo but had no luck so maybe it is leaking from there i have no ideaaaaa!!!
can someone pleae help me here??

 

Where is the leak coming from? Alot of the time it is the oil return line that leaks. Did you rip the gasket by accident? Changing O2 housings won't make the seals go bad in a turbo unless you fully drained it of oil and coolant and dry started it.

 

i did rip the gasket but then i changed it today and still leaking, dont know from where but when i started the car it was leaking down the o2 housing and wastegate

 

You look at the oil feed line coming into the turbo? Maybe it's loose or you somehow punctured it?

 

Or you forgot to put the copper crush washers in.

 

i had to put RTV on that gasket for the oil return line... same thing happened to me, replaced the gasket and it still leaked, put RTV on, no more leak..(if thats where it is comin from) should be noticable.. let the car run and lay under there

 

i dont know what that copper crush washer is... which side of the returnbo line is it on??

 

If the oil is leaking down the O2 housing and wastegate actuator, then it's coming from the oil feed line at the top. The bolt that holds it to the turbo has 2 copper washers. One goes on each side of the banjo fitting. (the hole of the oil feed line)

 

Excuse me, but how/why are you running two posts simultaneously. one titled, Oil Leak in Turbo, and the other entitled, Oil Leak from Turbo?

 

yeah sorry about that i thought it to be better suited in this forum not the other

 

i checked all the banjo bolts though, and there is no oil on them

 

and if someone could please explain what this copper crush washer is it would be great thank you so much

Look at the pictures you see those copper washers?? They go on both sides of the banjo fitting. That is what they are talking about. Check those. If you broke the turbo apart, you unbolted the oil return line.

 

thank you thats what i thought they were talking about and i checked all those and they are fine... is it possible for oil to be leaking from the center section of the turbo from when i was trying to split it??

 

This exact thing has happened to me loooks like its coming from the center of the turbo after I installed the o2 housingand exhaust manifold.. I however did not rove my turbo..

Evokid have you figured it out? if so what was it and what did you have to do?
