Bent spark plug on 03 mitsubishi eclipse gt

This is the second 'bent spark plug' question I have ever seen and both within the last few minutes. What bent? The tip? Ceramic does not bend..I am missing something..

Where you set the gap on the bottom of the spark plug.. it seems like something is coming up and hitting it causing it to bend

OK that makes sense. Are you sure you put the right plugs in, and not too long a thread that sticks down too far in to combustion chamber and was hit be valve? Compare old to new?

Ya same exact length. The old spark plug that was in that cylinder wasn't tightened down at all. As soon as I tightened the new one it started hitting it

What brand and number plug are you using?

Autolite platinum ap3923

Was checking applications. Geez... you got me, it is the right one. not like the old one was not hitting because it was loose.

Sorry man I am stumped now

Ya I been stumped I just hope it's not my piston or anything.

3.0?

Yup

That is an interference engine, so tolerances are so friggin' close, maybe some sort of valve lash issue. Valve opening too far or duration too long Throwing guesses but don't know what else to do

Naw forget that. Would not hit plug

Idk I'm going to tear it down and see what it could be

What I can do is drop a PM to a friend that has one, and knows them maybe he can help..dandyoun, he's up there on this page,

You know what, it obviously can't stay that way so I think that's a good idea

Anything would help at this point

Was car running real bad and backfiring some why you changed the plugs? Sounds like you might have bent valves and they contacted the plug. Not a hard fix for a DIYer just time consuming. When you take head off make sure you inspect for damage to top of piston too.

Now if no bent valves(with head off) then screw all your plugs in that head and inspect to see if the one that was loose might be sticking out farther than the others.
