So I want to drop the engine to install a CHT modification under the spark plug hole.
I also need to install a crank sensor. I am a bit hesitant because I don't want to risk pulling an exhaust stud out like last time. I suppose it's a good reason to address that bolt again? I feel it is loose or something because the exhaust is kind of loud in my opinion but arent they are loud, to begin with?

Well if it is loose what is the proper way to fix it? Take the block to a machinist and have them fix it? I feel my previous repair was not good enough. I drilled it out, tapped it, then installed some time cert and the stud.

I just don't want to open a bigger can of worms.

Whatcha all think?

Thanks guys!

No problem to leave the he’s on when you drop the engine.

The only things I take off my drivetrain when dropping the motor are the oil filler, dipstick, and throttle body. No need to remove the exchangers at all! Oh, I also do remove the muffler.
