Ok, so I got my valve adjustment about a week or so ago. The first startup after the adjustment sounded so quiet and running like a top. Then lately it's been sounding noisy again!

I had two loose valves and now sometimes it still sounds like their loose. It's weird because I had one night where it was running awesome, It was quiet and no engine noise, it was literally purring. Then there are other times where it's loud and clanky. I don't understand how this can be...

are the adjustment nuts "locked" together.

might want to pull the VC and check then, or take it back to the mechanic.

Alright, cool will do! Weird how it just keeps going back and forth, from quiet to noisy. :/

could the be that the nuts are loose causing the valve(s) to adjust by themself.
