Actual oil leak or bad turbo???

[NAT01]

Well, I'm still continuing my endless quest. If you've seen my profile my wishlist it says "no leaks", so here's another pic. I'm thinking that it could possibly be the seal in between the exhaust manifold and turbo. I'm a newb when it comes to DSMs. There is some oil residue on the nut where I have placed the arrow. Also, it looks as if some oil has gotten into the intake side of the turbo. What I don't understand is that the turbo was just rebuilt about 7-8,000 miles ago. I'm hoping it's just this seal. I have the stock 14b with a boost controller set to 15 psi. Can anyone help me out? I appreciate it.


P.S. - If anyone knows of someone or lives in the northeast PA area and wouldn't mind helping a fellow DSMer out, just PM me. Thanks again

If I were to tighten down on that nut, would it do any good? Or is that just a cover? Thanks

That's the ring clamp to hold the turbo together.

It's common for oil to get into the intake, it comes from the breather hose on the valve cover that runs back to the rubber elbow between the MAF and the turbo intake.

Should I just go ahead and tighten down on the ring? Just to make sure then? Is there any other possible reasons why oil would be dripping down in that area? Thanks for any help. I really appreciate it. Once again, if anyone is in the Northeast PA area, and wouldn't mind helping a fellow DSMer out, thow a PM my way. Thanks

So where exactly is the oil comming from? Or is that what you are asking? If it is comming through the exhaust manifold and down into the turbo then you may have bad valve seals. I really dont see how that could happen unless the seals were REALLY bad though cuz I would think the oil would burn up before it got all the way down there. Other places could be the oil line that bolts to the head, or your valve cover gasket. Oil could be dripping down from those places so check around. It could also just be that you need to tighted the bolt that connects the oil line to the turbo.

All I can think of for now.

i'll really have to get down underneath there and check everything out again. i wouldn't think it was the valve seals. the head is newly rebuilt. this is why i would really wish that a fellow DSMer would maybe be able to take a look and give me their personal opinion. Thanks. I guess i'll post again when i can take a better look.

Yeah the more I think about it, I dont think its valve seals.....I dont know why I even said that, sorry.

Just try simple things like tightening a few bolts that you think could be leaking a little and wipe the oil off the nut and see if it comes back. How much oil are we talking here? Is it leaking enough to where it makes a spot on the ground?
