Hi Folks,
After dealing with SBCs for 40 years, this is my first foray into Pontiacs and their maintenance and I have a question about the Pontiac cooling system. Background: 1970 GTO, Std 400, Auto, PS, PB, and AC.
Problem: I have an oil leak from either the front of the oil pan or the crank seal - can't tell which.
Well, in for a penny, in for a pound, so I ordered the Felpro 45166 timing cover gasket set. So, the manual says to drain the radiator (which I'll remove to provide more space in which to work anyway), as well as the block (something I never had to do with a SBC).
Is draining the block absolutely necessary or can I skip that part?
I just changed the oil and don't want to risk any contamination when I pull the water pump or timing cover. Any other pointers about timing cover removal would be greatly appreciated. Thanks.
