This is the 1st I've heard of a hyd flat tappet wanting lash. Usually they are tightened 1.5 turns past 0 lash, to get the adjustment in the middle of what the lifter can adjust for.



He never said lash , he said PRELOAD , .080 is too much , even .040 is a little excessive .

Crane Golds are not roller bearing rockers , the body rides on the shaft .

OP , have you pulled the shafts and rockers to see if there is anything going on?

Also when you say you checked the shafts I assume was no wear where the old rockers rode on the shaft ?

How did you go about setting preload , ?
