Default Reusing flywheel bolts?

Hey is there a limit to how many times you can reuse a flywheel bolt? This is the 3rd time I am going to be reusing it. If they do not look worn or bad am I good to go? Sorry just paranoia asking lol

Reusing them is fine. Torque them to spec. Then torque them to spec. Then check the torque on them. After torquing them to spec. While torquing them to spec. In the correct pattern.

I don't use thread locker. As per Honda's recommendation, I clean the threads thoroughly and install them dry.

But threadlocker *probably* won't hurt.

As long as the bolt threads/heads aren't stripped, I wouldn't worry about reusing them. Just be sure to clean the bolts and threads on the crankshaft prior to reinstalling the flywheel. I've never used threadlocker on flywheel bolts but if you choose to use it, dont use the red version. It'll probably make removing them a hassle next time around.

I reused the same ones countless times. I've used blue thread lock on them everytime. Not required but after seeing a friend's flywheel shoot through the hood and cut through the engine/transmission casing due to poor torque and bolts backing out I'm not taking any chances now lol

How'd the flywheel shoot through the hood and cut through the transmission casing with the clutch pressure plate still attached to it? I'm sure there would be some other type of failure before the flywheel goes shooting out of a hood.

The whole assembly goes shooting through the hood. Those little teeth on the fly wheel act as a saw. Bolts come loose, flywheel is spinning at 8k+ the the whole clutch assembly cuts through everything.

The flywheel acting as a saw blade to cut through everything isn't likely. The instances in the link you posted showed tranny cases blown open and hoods with cuts from debris shooting out as a result of a transmission failure, but the flywheel was either shattered into pieces or missing. Didn't see an example as you describe.

Read into the post however you feel like it. I've seen in person what happens when bolts come loose and it was the clutch and flywheel sitting on the ground.

The flywheel and clutch are retained by an input shaft. An exploding clutch is more likely to cut through a trans than a flywheel coming loose.

A loose flywheel makes a LOT of noise (I know). It takes days of driving around with said noise for the flywheel to come loose enough to disengage from the crank. At which point, it would spin at input shaft speed. Sure, there's a lot of stuff going on and the input shaft may break and the assembly may come flying out. The trans housing is weak. You can break it with a good hammer blow.

But...the cars in the pics likely had exploding clutches at high RPM that tore everything apart.
