Guys, this is what can happen from washing your engine.
I had to swap in my new LS6 PCV system anyways so I took the opportunity to install the new valley cover while swapping both knock sensors. Sealed the new oners up with a special quick drying adhesive... worked great.
Anyways.. if you havent sealed them.. and wash your engine.. may want to go for a drive after washing it cause the puddled water WILL cause this problem.
