I was preparing to change my air filter today on my ’01 L, and noticed a fair amount of motor oil trapped in the bellows or corrugated portion of the elbow between the filter box and TB. Is this from the pcv valve not being 1 way?

The bottom of the TB blades are also bathing in oil..

How do I fix this problem?

I would imagine this is not good, and I will need to remove the whole intake track to clean everything, including the intercooler.

I’ve heard of 2 fixes, an oil separator, and a cobra pcv. Will either or both of these fix my problem (assuming this is the problem)? What else can I do, what other options are there?


TIA,
Ryan

 

Get a cobra PCV and stick a dime in the hose on the back of the intake. That should get rid of most of your oil problem.

 

an IC cleaning and blower cleaning might be avisable if you're that forgone.
