Hi, if i put loctite on the bolts should i adjust the torques lower. This is for the timing belt replacement I am doing.

No, not for the bigger bolts.

it does make a difference but the only important bolt is the crank which should just be frikking tight,

you merely use a torque wrench to the setting nominated and many torque settings are not critical.

So what you're trying to say here is that the design engineers decided that a torque setting for bolts wasn't really that necessary and us backyarders could just ignore them?

A bit like your doctor or pharmacist providing you with a recommended dosage for a particular drug as a conversation starter???

I cannot say for certain that wet or dry will affect torque settings, but I do know from experience (and failure) that if a torque setting on a bolt says to torque said bolt with a lubricated thread (say like the head bolts) and you don't lubricate them, you can lose quite a substantial amount of torque.

So ignore them at your peril (and remember the old adage RTFI).

You don't lose torque, you get exactly what you applied. You lose clamping force, because some of the torque is just overcoming friction.
