Thread: '03 3.1l

So, my wife has a 2003 Grand Prix SE with the 3100 V6 (which, in my opinion is better off as a boat anchor...).

3 different times now, one rocker arm has dethreaded itself from the cylinder head. It's been 3 different rocker arms, but each one has done the same exact thing. The first time it happened was about 2 years ago, but then we had it happen a 2nd time the first week of January, and now again this past Friday.

Has anyone come across this problem before? Or heard about it? Everyone I've talked to is baffled as to why it continues to do it, and my mechanic can't figure out why it continues.

Thanks!

i got an 02" 3100 and i never heard of that happening,,wish i could help,,good luck

My mechanic has only ever seen it happen once in the 25+ years he's been in the business, and it's happened 3 times to my wife's car alone >.< It's obnoxious, especially since there's 9 more that can go...

I'm thinking it's time to sell her car lol
