We are currently in the process of replacing the exhaust manifolds on both of our 8.1s. While removing the old bolts (32 total) almost half snapped off and had to be drilled, easy-outed and/or left hand drill bit out, and/or collapsed with pieces pulled out (what a job that has been). The question is this: does anyone ever add any type of coating/sealant to the new bolts before installing them?
thanks
