Just a little help...GEC52 will chime in on Tuesday or Wed...
He has had issues with rockers breaking...he has replaced several on different cylinders. He gets about 20 miles on them and them one breaks. Joe H is on the mark for what GEC figures is doing it...the head has been milled too many times... the intake (?) valve is flat and makes impact with a piston..not enough to wreck the piston, just enough to destroy the rocker.. GEC was thinking of trying two head gaskets to get a little more clearance between valve and piston....
further thought is that it takes the engine being warm and everything expanding just a little before the impact occurs...
Click on his profile and search previous posts...he has a couple of threads going on his problems...
His truck is looking VERY sharp..he just needs to get the rocker issue solved to get on the road....
I have a 58 235 he is looking at installing, but he would like to stay with his 216...
Just little more info on his problem to keep the answers coming until he gets back....
