I’ve got a freshly rebuilt 292, 0.030 over, new crank, rod and cam bearings (original cam), new pistons and rings, new timing gear set, new oil, fuel and water pumps, valves hand lapped with new springs, rocker arm shafts, and valve stem seals. It runs with compression of 140-145 at each cylinder.
It runs pretty good at idle (450rpm in gear) but as you increase engine speed there is a miss that gets more noticeable as speed increases. Manifold vacuum is about 19 at idle but there is a slight bounce on the needle.
I put on an electric choke cap and removed the heat riser tube that was connected for the old cap.
When running there is a small amount of water coming out that heat tube hole in the intake manifold. If you rev the engine it blows a little more water out of that hole. The water does not smell like antifreeze, actually it has no smell to it that I can tell. The amount is small but I think it is more than just condensation build-up.
The intake seemed to fit nicely and I used new gaskets and torqued to specs.
What can be causing this water leak? Is it common to y-block and is there a fix? Is there something in the exhaust crossover I need to check, intake gasket or something else?
