To all GMC people with roller follower cams, please be aware of this issue.
An owner has had a recent issue with an engine built and installed last year.
The engine was built with a Competition Cams 42-413-9 Roller cam kit.
It wore out the distributor drive gear in about six thousand miles. In a query to Competition Cams, he found out that they only expect five thousand miles of life from the bronze distributor drive gear.
If you have a Comp Cams Roller, carry a distributor drive gear and the tools to replace or a back-up distributor and plan to replace this gear on a regular basis.
Unfortunately, this owner only works the GMC-EFI group.
More information will be available as more is learned.
