So I think I have a bad lower intake gasket. When I put my hand over the oil fill hole its sucking air and it idles high. I have the Professional Products Typhoon intake. What gasket sets and numbers should I use? Thanks!
I assumed he though he had a gasket issue so I spit the numbes out. Yes vac present is normal to an extent, it should not have so much vac that is sucks your hand down.
Why do you think it is an intake gasket, other then the vac you feel? Have you checked the PCV valve?
I had an intake gasket go before and it was kind of like this. But, I sprayed carb cleaner all around where I could reach last night and it didn't do anything. I'll check the PCV. What else could it be?
