I have an LT1 that was rebuilt 24k minles ago and about a couple months ago I noticed oil leaking from what seemed like my oil gasket from the water pump. So after holding it off i went ahead and replaced all of the gaskets. Timing cover, water pump, opti, and the crank and I still have the same leak. Could it possibly the oil sending unitl or a pvc valve??:confused: I'm getting tired of cleaning oil off my engine and garage floor. Any thoughts guys? Thanks.

They make an additive that you can put in your oil and flouresses under ultraviolet light. Leave it in for about a week and it will show you where the leak is coming from.
