Hydraulic or Solid Lifters?
I am doing a top end rebuild on my 1949 248 and am embarrassed to state that I do not know if I have solid or hydraulic lifters. I have two reference manuals and they contradict each other. My lifters look like they are made of two parts. The inner part has an oil hole and is retained in the outer cylinder by a wire spring retainer. I am unable to move the inner part when I press on it. I do not want to disassemble the lidter for fear of damage. I assume a solid lifter is "solid", made of only one part. Does anyone has a suggestion or how to tell them apart?
