I've heard 20 at idle and 40-60 high idle,hot.My 8070 is just under 20 at 800rpm and about 55 in the field,hot,with 30wt Rotella.Had to crank the relief in a bunch to get it there.3_4 plug right behind turbo drain tube.Had to remove tube and hose to put a socket and breaker bar on plug initially to get it to turn.End wrench worked after that.The old 426's had the relief to the left of the filters.It looks like a hex head pipe plug but it's straight threads.Crank it in!
