Should I use treadlocker blue (Medium strength) on the exhaust manifold Allen wrench bolts when reinstall? And how about the threaded bolt on the vary bottom of the exhaust. You known the bolt from hell.
Calls for Loctite 243, The regular blue is 242. I think your good to go. Like Mr. Mom "220-221, What ever it takes!" I think the only difference is the 243 is oil resistant. Just make sure the threads in the holes are super clean.
