Ummm, no. Sounds like a few guys around there still using the BFH installation method?

Isn't that like the "mechanic" in the neighborhood garage near where I grew up that used to tighten Chevy 6's headbolts down 'til they squealed then gave them another half turn?? He never had a return for a leaky head gasket .

Yeah, and if that doesn't work....you go to the RBFH method.....

I thought you tightened until you feel them stretch, then back them off 1/8 turn......

I thought it was tighten them until they strip and back it off a 1/4..

Oh yeah, don't forget that you can use that 1/2" drive impact wrench for everything!!!!

So that's what I've been doing wrong.....Time to recalibrate the torque wrenches......

Well its fixed, it was the balancer, took it off today, and the outer ring had slipped forward about 1/4", got another one from an old motor, and no more wobbling, just thought i would update you guys on this, you guys were right.

we always are.... well at least one of us, when we through out 300 different suggestions then one of us should be right

I had this same problem - I found the keyway on the crank sheared out

Pretty certain it happened while doing a 120mph/high rpms and turning on the A/C - I wont try that again.
