Are you adjusting the valves hot?

they need to be

If you hear clanking then running it is likely doing damage. That will lead to more costly repairs or ruin it so bad it becomes scrap metal. Know any local car people yo

I already had mattressking look into it. He said valves were clanky but didn't mention a knock or anything else.

Enough play in it that I knew it was wrong. When you set it to the proper clearance it should stay there, not another 5-10 thousands off every time you test it.

My compression issues were due to broken piston rings.

what was your compression at?? did they use the wrong rings?

I was off by about 4 thousandths maximum on one reading, usually about 3 thousandths off. this was doing it cold though. might try hot measurements and valve setting next!

awesome.

I'll try this later.

I just put on a new to me rocker assembly that doesn't have a crack halfway done support tower 1.... lol.

ill drive it around the block then adjusts hot.

I'm sure ill have to adjust again after everything "wears in" as they say.

Well, he has hands on - I would follow his advice. Loose valve clearance could clank I guess. Can you look into the cylinder with a mirror on a camera probe so you can see back up to the valves?

I forget what my compression numbers were, but they were an obvious problem, like sub 100 in a couple cylinders.




Set the clearance cold.

Run it to bring it up to temp.
Set the clearances again to spec.
Then check everything again.
Rinse, repeat.
Enjoy.

This. Cold setting won't be far off from a hot setting, and close enough that the 2F will run good enough. Set them cold, drive it for 20-30 minuted to get it hot, then recheck and reset the valves.
