south texas | So during the obc method, your claiming the cam/push rods are at the lowest piont and during ibc method they are slightly elevated. I am a novice at the 855 but it seems that the obc method has the inj set when the cam is pushing on inj, valves completely closed. While the ibc method has the piston in the same position but ur setting the lash on a different inj with 0 load on that inj.
maybe i misunderstood but i don't see how there are 2 different settings for valves if they are completely closed.
i have no questions about setting the inj, just about why the lash on valves is different than my tag.
im looking for tag pic.
the stc inj take 125 in lbs | |
