oil seperator - 986 Forum - The Community for Porsche Boxster & Cayman Owners

i have a couple of questions about the oil seperator on a 1999 2.5 w/56,000 miles. i disconected the j-hose that goes from the seperator to the throttlebody at the seperator end and stuck my finger in the hole on the seperator and there was oil in it, would that indicate i need a new oil seperator???
2nd question i have is what is the purpose of the oil seperator? is it just smog equipment? could i just plug off the hole in the throttle body and rerout the j-tube to the oil filler tube or just put a breather on it???

The oil/air separator pulls the air from the oil before it is recirculated back into the engine. If it is not working properly, air is still mixed in the oil and your engine could seize.

As for the oil at the throttle body end, I don't think you should see oil anywhere near the throttle body. If your separator is going bad, replace it or it could go from a $100 fix to a whole lot more.

thanks, so if there is no oil near the throttlebody its ok?
when i checked it i stuck my finger in the oil seperator itself not the throttlebody, and there was oil in the seperator

@ yfz,
I had the same issue you did and in time it caused a CEL.
Here is my write-up on it.
How to remove/install oil seperator
Just change the part anyways if you have faith in your mechanic skills,its been resigned a few times.
