Just wanting some opinions on using 680 loktite on fitting threads going into heads & HPOP,I think some don't use loktite ?

 

The fittings in the heads don't get any thread locker, just the ones in the pump itself.

 

Ok Thanks,I quit searching & went to dieselorings.com & found a nice seven page write up with toque specs.You & Bob agree on the loktite application,I got the cart ahead of the horse & installed the IPR,but need to pull back out for draining purposes.
