I have done everything with this block, this was the third time it has wipped out cam bearings.
This last time I installed Durabond coated bearings and then measured each cam journal bearing and then the cam. I then cut each cam jounal to give it 0.003" clearance. It turned real nice and I thought I had it finally fixed, NOPE!!!
When you say it wiped out the bearings, just some clarifying questions: 1) what does the failure look like ?
Camshaft Bearing Diagnosis 2) is it on all journals or is it a repeated failure on just one?
Random cam bearings, first time it was on #1 durring a dyno session, second time it took out #2, #3 and #4, this time it took out #2 and maybe some others I can't see it all yet (not taken apart yet).
When it took out #2, #3 and #4 I has to use a slide hammer to get the cam out
I'm telling you Ive have tried everything, I believe the cam bore is offset somehow. The block has been measured a couple times and I was told good to go both times by real good shops.
I'm not looking for the problem anymre I'm just going to fix it.
