Serious question, ever had a 12-hour day turn around because of one simple trick?
Spent all Tuesday in our shop in Boise chasing a phantom knock on a 6.7 Powerstroke, ready to pull the engine. My buddy just said 'check the flywheel bolts,' and sure enough, three were finger-loose. Anyone got a better torque sequence for those?

Check the flywheel bolts" is such a classic save, man. I always hit them with a crisscross pattern from the center out, but the real trick is doing it in three steps, like 50 ft-lbs, then 75, then the final spec. Clean threads with brake cleaner and a drop of blue loctite are non-negotiable too. Seen way too many come back loose because someone just zapped them on once.

Used to just torque them to spec in one go and call it done. Had a dual mass flywheel come loose on a TDI and the noise was awful. Started doing the three step method with cleaned threads after that.

I get the three step method, but honestly I've never used loctite on flywheel bolts and never had one come loose. Just clean threads and a good torque wrench has always worked for me.
