i have an air leak coming from this circle object on top of the engine, the car idles anywhere from 2000 1000 rpm. u can hear the air leak for about 30 seconds after you cut off the engine. traced it back to the circle object on top of the engine

 

Got to be the PCV valve. Thats a symptom of a bad one, and they are round. It's on the top front of the engine under the cover. I'd still have someone verify that's the problem, but wouldn't be suprised if it is.

 

Is that whole thing the pcv valve? The circled object creates a suction and when you cover the whole the engine revs up to 2000 it goes crazy

 

Got the name of that entire piece, it's the Crankcase Vent Valve.

 

aka PCV. get the newest OEM PCV installed and it'll run like new.

 

Don't forget the bulletproof BCS one out there. Works great.

 

indeed i got the revamp kit for mine no problems so far.
