I notice that after heavy boosting I get a whiff for a few seconds of burning oil. It happened with my last turbo and my brand new one. No smoke from the exhaust.

Is this typical?

 

How much boost are you running?
are your ring lands in good shape?
is blowbye a possibility?

Damn, I was about to start the very same thread. Here is my problem:
Blowing good amount of blue smoke after warmup and, well pretty much any time after that.
Just did a leakdown and compression. Had less than 5% leakdown and compression was an average of 175 across the board.
Dropped the downpipe and intake and inspected for oil--none found.
Replaced PCV.
The only thing I can figure is that the valve seals/guides are the culprit. Either that or the oil log thing on the back of the block.
Anyone have any suggestions??

 

There is a PCV valve in a(black box, I think its an oil vent) at the back of the block, mine was leaking oil down on the exhaust and everytime I did a power run, it would leak and cause a lot of smoke, it filled the car with smoke sometimes. just change the O ring and check the hoses to and from that same vent.

 

I boost anywhere from 6-10psi. I smell it after any good run no matter how much boost but more with more boost. I have no oil in my breather line going to my intake. I have a new pcv valve. I know there is always a little oil in that. I have a catch can I was going to put in line before the pcv valve goes to the intake manifold. My compression is very good - 210-210-210-210
I have 75,000miles on the car - stock engine.

I have this same problem.. but my problem I'm sure stems from the fact that I
have a small leak on my oil return line that hits the DP..

I guess also that some oil smells can come out from the valvecover breather.

 

Take this one up again.
Some commented on having oil burning onto their exhaust. My oil burning is actually coming from the engine through the exhaust.

 

I have the same problems with my car. I've had my Drag for over 2.5 years and i've put over 40K miles on the turbo alone (car, Teg RS B18B, has a total of 103K miles). I smell oil following hard driving/boosting. Compression reads good (190+). The problem was there since day one of the install. Checks show no oil in intercooler/piping, everything checks out okay. My guess is, a small amt of oil passing the turbine seals and entering the turbine/exhaust and getting burnt.

 

cool. glad i'm not the only one. I hope its nothing. I'm running mobile1 5w-30. Perhaps some of it does slip past the turbo seals. I guess thats ok. that should not harm the turbo and is best for the engine? When i'm idling and I put my nose in my exhaust pipe, i don't smell any oil just fuel.

 

Hmm, I think I definetly have a valve seal problem then. My **** smokes a hellofalot....guess its time to have some headwork done. Damn, p&p, springs, retainers, valves, guides--here i come.

 

The valve stem seals would cause oil burning. I had a bad valve stem seal in my head and it ate up 1.5 quarts of oil a week w/ the same symtoms as everyone said. How did i know it was the valve stem seal ? Well when I took my head apart, all the seals were a boitch to take out EXCEPT for one seal which came out with ease.

 

Yeah, it's possible valve stem seals would cause oil burning. However, i started smelling oil just after i installed the turbo (day one). It has stayed the same since then. I've been running castrol syntec 5W50 since 40K turbo-miles ago.

In short, it's highly unlikely (in my case, at least) that valve stem seals are the cause of my oil burning.

 

Good to know Just what I was looking to hear. Weird, Im using about the same amount of oil.

Anyone know of any good sites on a how-to on replacing the seals? Which seals to go with, factory? Should I do the guides, or are they one in the same? Should I do springs and retainers too--since im in there? And which tools to buy-- Snap-on preferred!
