Milky substance on the inside of my valve covers.......
#21
I was thinking of removing the PCV hoses entirely, plugging any holes in the valve covers and intake manifold that the hose connected to, and just installing a valve cover breather so the crank case can still vent. This would eliminate any issues with oil in the intake, and since this car is drag strip only, I could just change the breather out for the oil fill cap when the car is sitting so no moisture could get inside the car, and whenever I needed to fire the car up to move it or run it just pull the cap and put on the breather.

Put a scanner on your car when the oil gets in the intake and watch the spark knock and you will see why you need a catch can.I was getting spark knock until I put the catch can on my car.

Mine was letting quite a bit in.Mine would smoke real bad when I got on it.I know it was killing my power.You spraying you blowing it all out ha ha.I was surprised when I put the autoxray on my car and went down the road I wasn't hearing it but it was getting some pretty good spark knock.My trailblazer ss is fixing to get a catch can.After running a scanner I am a firm believer on the catch cans.Not no ebay one either.

Hi,
if you have any reservations about your issue: Do a compression check and this will rule-out head gasket issues and other related problems. Vacuum check will show valve train issues and leaks. Good luck........... Merry christmas.............

Also, burning oil leaves crusty deposits (which also promote detonation).
