Anyone ever have an exhaust manifold bolt randomly break?
04.5, all stock. Nothing's been touched since I've owned it (2012...so a minute). 197k miles. Only semi-recent thing I did was put a turbo back exhaust on the truck about 2,500 miles ago, but obviously only had to unclamp the one clamp on the down pipe. Anyways. Truck got a weird noise at various RPM's, and really sounded like it was turbo related. I inspected it, and the two most rearward (firewall) bolts just broke off. I can see the hint of carbon build up around it as a result.
What would cause this? Measuring the amount of bolt left, it looks like the bolts probably broke almost flush with the head. What gives? Looks like a right angle drill is a must have to try and drill these out. I'm just perplexed on what in the world could cause this, out of blue? Surely I can't be the only one?
