Thread: I think I have a BIG problem

Tweet

I removed the top half of the motor in a couple of hours this morning and pulled #1 I & E roller lifters. The exhaust lifter would compress with finger pressure. The intake was dead stuck. I couldn't move it at all. Totally different 'feel' than the exhaust.

I removed the retaining clip, disassembled the lifter and couldn't see any dirt or anything else wrong. Then, I completely cleaned it with solvent. When I reassembled it, it seemed to work OK. I'll probably replace it anyhow.

BTW, as soon as I took this photo, I plugged the I & E exhaust ports and covered the galley completely to keep the junk out.

Cleanup and reassembly will take a bit longer.

Denny, they are absolutely dead center left to right. Of course, as the valves lift and fall, the roller does sweep across the top of the valve. However, I have checked them through several full cycles, and sweep about the same amount from center each way.
