Possible damage to spark plug hole threads, Considering Helicoil, Seeking some advice
Okay, I don't know for a fact if they are trashed or not, but here's what's going on with it..
The #1 spark plug goes in and tightens like the others, but then there's just this 'slip' feel when I'm done tightening. It's happened the last 3 times I've messed with the plugs, so I don't think it couldn't be completely stripped.
I'm not going to touch them until I re-work my head anyways--
I HATE aluminum threads, just cuz they get damaged easily. When I have the head off, what would be the drawbacks to helicoiling all 4 spark holes?
Even without thread damage, I would like to reduce any chance of future mess-ups.. I figure for a few bucks it could save me a huge headache later on.
