oil in intake


Heza

Recommended Posts

ok...so i pulled the upper intake plenum and front cam cover off of my '96 to send to DykZ34 to polish. however, in the upper intake plenum there was a noticeable amount of oil just sitting there. what the hell would cause this? im almost partially worried about it.

Are you sure its oil and not just carbon deposits in the intake? Unless you have monstrosterous amounts of blow by its unlikely to be oil, even then thats really odd.

 

when you can pour the shit out of all 6 intake ports and see it puddled in the head of the plenum, im sure its not carbon.

too much blowby arround the rings, causing oil buildup in the pcv system pushing the oil up into the intake manifold. (that's the typical cause) or it just could be a bad pcv valve causing oil to slip past and into the intake.

if it's a fresh motor, the rings may not have seated yet.

 

you can make a little catch can (I did) by using a bottle with a long stem, and a short stem, so it looks something like ...

that'll keep the oil outta your intake.

You may have an internal vaccum leak through the intake gasket, where it sucks oil through the lower intake gasket...if the intake gasket isn't fresh I would change it just to be safe
