on the freeway climbing a hill, I lost power and my turbo gage spiked up and down like crazy. had it towed home. the seal in the turbo was leaking on top. I had oil from my filter to puddles in my manifold. I had a second turbo that came with my car so I installed that one. cleaned everything out I could. no spark turned the motor a few times to push oil out before firing it up. fired him up, warmed him up, and did a sea foam treatment. by the end of the treatment, oil was coming out of my turbo at the seal again with oil all through my intake system again.

I have a 93 legacy RS turbo. stock 2.2 with stock turbo.

Welcome to the BBS.

Have you done any additional diagnostic checks to see if your oil pressure is ok? Are you running the stock turbo oil feed line? Is the oil drain line free and open to allow oil to drain back into the oil pan?

Any additional information you can provide will be helpful.

I ran a diagnostic and I got 4 codes..

11 crank angle sensor

23 air flow sensor

24 air control valve

49 air flow sensor



it pushed most all the oil out through the exhaust. dripping out of the bottom of my headers that connect to the cat. conv. both sides.

Hi Sean,

I really think you've got a plugged oil drain line back into the oil pan or something has dramatically increased the oil supply. I would probably lean towards the oil drain line being plugged. Have you looked into that?

I don't think the codes are going to tell you much at this point as this problem is more mechanical than electrical.

Before the oil issue did the car run fine?

I would recommend inspecting it first to see if it's blocked. If it's not blocked, there may be something else going on.

okay, todays progress. turbo out, oil drain line has no build up or gunk in it. the metal line going into the crankcase had no gunk in it to the elbow.

it appears to be the original oil feed line.

it ran okay before this happened. it had symptoms of a bad pcv valve. rough idling, some loss of power sometimes.

Pull your oil cap after its been run to temp and shut off. Lots of smoke??
