How to Assemble the Front of a Small Block

Hey Karl/Folks,

Can you tell me which of the water pump/timing cover bolts require sealer to prevent coolant leaks? Marked the old bolts when I pulled them, but like a dummy cleaned them w/o noting which ones had sealer on them :banghead: Ended up getting new fasteners anyway....

Be well and thanks in advance.

I believe that it's all four of the long bolts. I know a couple of the go into the water jacket for sure.

I also use the silver powder "stop leak" and it will seal them after everything is together. Don't use Bar's leak, it will clog the heater core - too thick.
