Yes my Stant pump up kit is a bit leaky but on this I drilled/tapped the stat housing extension for a brass schrader valve & pumped it up directly with an air hose/chuck from the compressor. What I am really after is to find out if it is the head gasket(s) or the intake gasket(s) so if it is the intake gaskets (whichever side) then I dont have to pull the heads
