Hey all, I've got an issue with my water pump (351 W). I developed a leak at the bottom of the pump and I had to replace both gaskets, have a plate between pump and block. After putting everything back together I still have the same leak in the same spot. As I was putting the gasket on the block I noticed a little vertical slit in the mating surface on the block. Now I am assuming that the pump bolts to the timing cover and not directly to the block. Is that slit supposed to be there and if so how am I supposed to close it up. BTW I put rtv sealant on the gaskets before installing and let everything sit for 26 hrs before refilling the coolant. Any help is greatly appreciated.
