My engine has exhaust leak due to the bolt heads breaking off by themselves. Three broken on drive side and one the passenger side. Never had this problem before, owned many chevy trucks, the best was a 92 chevy 1500 V6 4.3L and bolts didn't break off.

Whats to say the motor mounts rust apart to, is that be common. I've been buying new chevy trucks since the late seventies, I'm did all my own pairs untill lately due to my age. The best truck I had was a 92 c1500 V6 4.3 L ran over 300,000 miles without cracking open the engine, but the exhaust bolts never rusting off.
