1965 Buick Riv GS timing chain
While removing bolts on timing cover on the bolt
directly below fuel pump I heard a snap when the
bolt broke loose and water poured out that hole
when bolt was removed. Is that a problem or is it
normal for that to happen. Also its been over 20
years since ive worked on a car so before i get to
carried away i seem to remember that the
harmonic bolt is reverse threaded?
Upon further inspection it appeared that the bolt hole was simply in a spot that was within the water jacket of the block. I was careful not to overtighten that bolt during reassembly and have had no issues with water.
