Hi all. I am cleaning my throttle body. When I removed the intake-to-throttle body pipe, I noticed a decent amount of oil in there. I also noticed oil seeping out from the connection point where this pipe connects to the throttle body. Is this normal for our cars?

I can't speak specifically to the R but this is generally normal in turbo cars. My turbo BMW got it before I added a catch can and my 95 Silvia build got oil blow by and it was all factory for the most part. I assume there is some type of PCV system in these cars and this could signal that the valve could be clogged up and needs replacing. Could also signal that the turbo needs re-building if it's really bad but yours doesn't look that way and I assume you have some miles on the car so I don't think it's anything to worry about. You may also want to get some MAF cleaner and clean the MAF if it's got oil on it as well. Just make sure you only use the correct cleaner and don't touch the MAF element.

I've seen worse to be honest on other models and other makes as well...

How would oil get on his MAF? Air with oil vapors in it shouldn't flow in reverse towards the MAF/air cleaner for it to get his sensor dirty....Originally Posted by RVAE34

From the OP's sig "K&N" . Over oiling the air filter can cause oil on the MAF.
You are correct, no regular engine oil should ever get to the MAF.
2 different things.
And, fwiw, every turbo car I've ever owned has had a small amount of oil after the turbo. Tiny amounts seem to be ok, just clean them up once in a while...

Oh lol I didn't want to assume anything in case I missed it. But yeah unless he's soaking that filter in motor oil then there's no way it'd build up that much by the throttle body from an air cleaner, I was hoping that wasn't what he was suggesting.

I just opened the hood and checked and you are correct. I assumed these cars were blow through and that the MAF read the actual air going into the cylinders.
OP, that's a normal amount of oil. All Volvo's do this.
