1941 180 valve noise, The engine was not run in 35 years. After starting some of the valves seem to have excessive noise. I think I read somewhere that 1941 160 and 180s had hydraulic lifters. The engine has new oil and filter and oil pressure warm is slightly above 40 psi. But I think at least 2 lifter are collapsed.Is there any tricks to get them pumped up. Also all cylinders have compression so there are no valves stuck open.
