Please post any and all questions or discussion about this modification..
Joe, first of all, thank you for posting the pics of the cam shim installation. I know that it takes time and energy to size the pics and write the narrative.
I was unaware of this issue. I do have a few questions regarding this job.
[font color=blue]
1) Did Ford correct this issue on later models or is it still an issue on my 98? If not, do the newest 4.6 DOHC's still have this issue?
--I believe this issue was corrected on the tumble port heads (99+)
2) Do the problems caused by the improper tension manifest at lower RPM's or just at higher RPM's?
---All rpms's, But of course the more revolutions the engine rurns per minute the more this tension issue will affect the motor.
3) How long did the job take to complete?
---I can do it on a gen 1 in less than an hour. i suspect that I could do a Gen 2 in half the time.

Thanks again for the info and pics.
