I haven't posted for quite a while, have rewired, installed points plugs condenser coil,rebuilt carb, cleaned gunk etc and have tried to start the truck with no luck. Got a compression tester and we're showing no more than 65# in three cylinders and zero in the remaining cylinders..so, I pulled the head and found a valve sticking open. The reason the valve is remaining open is that the lifter is stuck ( it does move horizontally, but not vertically and has a lot of resistance, the motor turns by hand so I don't think the lifter is hung up on the camshaft. What would cause the lifter to be stuck ? Could it have somehow gotten out of round?
thanks for any help/advice you guys have,
SteveC
