If it is not leaking or making noise don't worry about it.
Yeah, but it will be leaking and making noise soon I bet.


Common problem with our cars, GM used Grade 5 fasteners and they get brittle in time due to constant heat cycles, usually the rear most bolts break first on the driver and paSSenger side. The extraction proceSS for the broken bolt(s) can range from "not so bad" to "living hell."

Do some reading on this subject, a wealth of info out there just waiting for you man.

Trust will need to fix this broken bolt iSSue in the not to distant future.

You have some choices to make (headers, Grade 5 replacement, Grade 8 replacements, etc).

Good Luck.
