Timeserts seems similar in approach to the helicoil solution, using a different approach. Room is tight and I couldn't use the full tap handle like that, but I have been jerry rigging solutions that work so far to allow me to drill out the bolts and turn the screw extractors and could probably do something like this as well. As long as if it gets screwed up, I can pull the engine and get it fixed. Is there a reason that timesert is better than helicoil?

Also, it seems that it would make sense for me to try to clean up the hole enough to use the permatex epoxy solution and the standard size bolts first. Permatex will hold to 128lbs of torque so it would be plenty strong, if I can get enough thread in there for it to adhere to. Even if it was slightly weakened, it should be more than enough for this relatively low torque application.

Agree that I should do all the tapping by hand regardless of the approach.
