Hey all: Your all right. (except we have no pcv valve). It wouldn't run as good as it does if there was a hole in the intake. The maker of the grease states it's melting point is 300 degrees. On the bench I heated up some on a metal plate and it would melt and slide off the plate at 190-200 degrees. I'm assuming the grease isn't blocking the drain back holes if it melts fairly ease. (no plugged holes on the first rebuild). I guess that does leave me with rings not sealing because of the grease. You all helped me realize that, thank you. I'll let ya all know when I tear down and get it back together. Thanks again for all your help!!!! It is appreciated. Later
