Does anybody have any idea about why im getting oil in throttle body? I have an 03 sedan 6mt stillen stg 2 with z tube and stillen gen1 catback. It only has about 60,200 miles barely on it. I need some advise. I noticed 2 weeks ago when i was trying to clean my throttle body a small puddle of oil in throttle body. I hope its not bad.

 

excessive blow-by. Get an oil catch can.

 

^ what he said it use to happen to my integra all the time it did reduce when i chaged out the valve guide seals but im sure you dont need that done

 

Thats pretty weird. I didnt think about the catch can. But how does the oil travel upward towards the throttle body? Is the oil traveling to the throttle body a bad thing or i should expect that until i get the catch can? Any info is really helpful guys. I have some general knowledge regarding this issue.

 

check ur PCV valves or all PCV lines... check the lines for oils .... and check any line that is attached on the back of the intake tube.

 

+1 prob coming from PCV
