so I looked to see if my plenum was doin ok and I saw a tiny tiny amount of oil on the left side...How long do you think i will be ok to drive the truck. Also does anyone know how much it might cost to get fixed. Thanx

 

A tiny film of oil is fine, it comes in through the PVC valve, which is on the lift side Sounds like your plenum is fine but to be sure get a mirror and look in the very back of the intake.

 

well that good to hear!! I checked pretty good I seem to be ok then.
