[DeTomaso] MME ENGINE - JESEL ROCKER ARM FAILURE

[adin at frontier.net]

Yep, they broke for a reason.  Hard to believe the rockers just broke.

Coil bind?  Too much oatmeal?  Chevy key chain?  O'bama/McCain/Billiary.

Checking the geometry is a MUST, imo.

somehow, I have to believe there are quality rockers that cost less . . . . .



Quoting JDeRyke at aol.com:
