Hello was told I should have my car checked to change headbolts. I’m not sure if my car is within the range of the issue. Not sure how to check I can provide the vin number if anyone knows how to check if I should be worried or not. Was going to do E85 and euro tune but holding off because I’m scared the engine won’t handle it.

Didn’t read the Forum FAQ at the top of the page, huh?
