I am planning on attempting to replace the lifters on my '55 Patrician. I just have one lifter that is ticking, but I figure may as well replace them all. I got really great direction from a member in Houston on my project blog - but I also wanted to post in the V8 forum because more info is always better.

Opening a can of worms, you are!

Are you just patching a problem or do you want to clean, check, fix everything While you're in there?

Replace the valve stem seals, disassemble the rocker shafts remove the end plugs and clean the interior of the shafts.

We always test the valve springs for pressure. About half are no longer as stiff as the spec.

Check the rocker arm tips for wear and regrind if necessary. Check the pushrod cups in the rocker arms. There have been a few cases of enough wear to capture the pushod and keep it from rotating.

Check your valve spring retainers for hardness. If a file easily cuts an edge, they're soft. A file will skate on the later hardened retainers. The '55 retainers were so soft, the keepers can pull through the retainer. Some may have been replaced already.

Is the oil pump still original?

Oil pump is the Olds conversion, it's just one lifter ticking and it comes and goes. I think I've narrowed it down to the #6 cylinder.

Oh and Jack - I'd love to really go ahead and fix everything while I'm in there, I'm just not sure my capabilities are up to the challenge. I'm learning as I go.

Yes, replacing valve stem seals in sutuis best left to someone with a bit of experience.

Definitely try something like Seafoam or another chemical first. When I first bought my car, the lifters were noisy. I used chemicals and got it down to about 10% of what it was.
