Oil leaking from thottle body

Mike_W · 05-07-2001, 12:00 PM

Does anyone else have this problem? It was like this before and after the Vortech. One guy told me to put a check valve(like the one in brake booster?) in the pcv breather (the one that goes from the back of the lower intake to to vacuum tree on the upper manifold). I believe this started after I installed the Holley intake. I did put in the metal plate on the bottom of the lower intake, from stock to Holley. Any ideas?

Unfortunatly a lot of us Holley intake guys are having this issue. I was going to relocate the pcv port to the bottom of the intake like the stock set-up, to see if that helps but then the oil will just burn in the motor instead of dripping out the TB. Some have just put extra long hoses on the PCV so the oil has to go further before it would reach the TB. I just went out today and bought a inline fuel filter like a carb car would use, I am going to install that tonight to catch the oil it cost me $2.50. While my motor was apart I took out my high volume pump and put a Stock volume in the oil in the TB has been much, much less so far.

JUST A FYI- When I talked to Holley tech, they told me to relocate it to the bottom and this is the advice they are giving people who call.
