Re: Compression test: low in 1 and 2 after gasket work

Quote:
My main question is this: assuming the machinist didn't screw up the resurfacing, is it more likely that I've got a problem in the block or a problem in the valves? I'm leaning towards the valves, thinking maybe the valve seals are cooked which may cause the loss of compression.
Thats a huge compression drop. Being those cylinders are side by side it would almost have to be the head gasket, cracked head or cracked something else but I don't thinks it's the valves or valve seals.
