CO54 Posted May 21, 2019 Report Share Posted May 21, 2019 Pulled the head off yesterday, manually turned the crank and verified everything is moving with pistons and valves. That was great news for a truck that was parked in '73. Otherwise engine history is unknown. All the exhaust valves are white with a chalk like substance. Input please?

kencombs Posted May 21, 2019 Report Share Posted May 21, 2019 73? Still lots of lead in gas back then, just phasing out.. Probably the source of the whitish deposits. 1 Quote Link to comment Share on other sites More sharing options...
