Exhaust leak again. Use Red Locktite?
Had an issue with water earlier this year with 2 broken bolts and one coming out on the purple manifold where it connects to the white one.
There was only one bolt left to hold things togeather.
Bought new bolts, new gasket and used Blue Locktite to assemble it back in place.
Everything was fine, untill yesterday.
Salt water in hull again, bildging a lot.
Looked under the seat and a bolt is again missing????
What have I done wrong?
Should I be using Red Locktite or would that be a mistake if I need to get it apart?

These bolts need to be torqued to 30 ft/lbs with Loctite Blue 242. Chase the threads inside the manifold with a tap to get out old Loctite, prior to assembly. The old crystallized Locitite prevents good adhesion.
The bolts (and nut) need to be periodically checked for tightness too. Red is only to be used if a bolt is never intended to come back out...I would not advise using it.

Bolts backing out
Make sure your drive line is okay. Vibration is the key to bolts coming loose - and if the driveline is not aligned it is a source of a lot of vibration. Clean the threads as XPS said. I am not using RED loc-tite for that application. If the bolts are backing out continously there is something wrong (cleaning the threads may reslove this issue) ...find it and fix it.

Make sure the two bushings and bolts that support the pipe on the side are ok too.

If those are the two that I mentioned, the one looks like it may have loosened up and/or the bushings are wore out. When they wear out it allows the pipe to move around and more stress is transfered to the head pipe and manifold. I would replace the bushings and at least one bolt. Chase the threads with a tap then blow the debri out and use blue locktite when you put it back together.
