It's been a couple months since I have done all the modifications to the truck. Complete tuneup, oil pump, timing chain, intake manifold, valve covers, water pump etc. I've noticed some oil on the new intake manifold, and it ended up being loose bolts on the valve covers. Retightened all the bolts and plan on watching them like a hawk. While I was cleaning up everything I decided to look down the throttle body and notice the light film of oil at the bottom of the intake. Is this normal or is something going wrong. I don't have the Plenum plate or gasket anymore. Could this be the PCV valve going bad? If so that would be an easy fix. Even though I've replaced my PVC valve when I did all the other modifications.

I read somewhere there is a aftermarket "Air Oil Separator" you can install, will that fix the problem, or do you think there's other issues going on?

Any suggestions will be greatly appreciated.

 

It is coming from the pcv. I don't know what brand you got, but don't buy a cheap one. A light film of oil is normal anyway, and nothing to worry about.

 

Thanks for the information. The one I have is an L cheap O from a part store, I guess I'll get a good one from the Steelership!!!

 

Yea, get an OEM or at least a Standard Motor Products.
