Turbo Experts -Oil leaks

[Xyster101]

I went to the track and was running my car hard. I noticed that I had oil splatter on the engine which was coming out of the manual boost controller bleeder hole. Then I pulled off my hot pipe and about 3 table spoons of oil came out of the bottom if the side mounted inter cooler.

I have a stock '95 MR2 turbo with around 100k miles on it on a '91 MR2 with 135k. Engine mods are a manual boost controller and turbo back exhaust. I have my old turbo, but the intake fins are smashed from sucking in a piece of plastic off the filter adapter the previous owner put on.

Can I swap the good compressor wheel off the '95 oil leaking turbo and put it on the '91 non leaking turbo, then put the '91 back on the car?

Do I just need to buy a new turbo?

How long will the '95 leaker run?

When it goes, will it destroy my engine or just leave me stranded?

I just don't want to drop $1k on a turbo right now.

 

 

Someone said it might be leaking from the PVC since the oil level was at the full line and I was running a track day. Here is a diagram of the engine bay:

If there is oil in the intake side and outlet of the turbo it is very possible that the pcv is leaking. Is your pcv system drawing vacuum off of the turbo intake pipe?

 

As far as swapping turbo parts goes, do you know how those turbos come balanced from the factory? If they are component balanced then yes you can swap your wheels no problem, But if they are assembly balanced then you can still swap the parts but afterwards you would be required to have the chra balanced.

Its your PCV. Supra does this (Did this) all the time , would always be a little spot of oil sitting on the compressor housing. Catch can time.

 

Also i got a old ct-26 that has a little bit of shaft play, but the fins and everything is good. Took it off for a upgrade to a 57 trim.

exactly what i was gonna say

Yep, time for a catch can. Replace your PCV valve while you're at it.

 

Most turbo cars will have a little bit of oil in the intake tract/intercooler when you take them apart, it's nothing to be overly concerned about unless there's a lot of oil in there.

I am picking up a Greddy catch can for $40 tomorrow used. I will toss that on there. Where is the PCV valve located?

If you look at this labeled image of my motor you can see the vent tube comes right out of the valve cover and into the intake before the turbo.

Ideas? Maybe I don't have a PCV valve since it is a turbo and it creates a vacuum on that line?

you can probably get either one of those turbos rebuilt pretty cheap at Columbus Diesel Supply

or send it in to blouch or dead bolt. They do amazing work.

Wow, I did not know you could rebuild a turbo locally, good to know. I will first try an oil catch can and see how that works.
