The engine has a hyd roller cam, so lifter seating is noy an issue. Oil pressure was 75# @ idle.
Even with the hyd roller lifters, I'm still getting some "ticking" up top. Pre-loaded lifters as per Comp instructiions. I'm worried about the roller tip rockers not rolling. (tip rollers were beat flat when I got the car with 478 mi on it) I had them rebuilt, of course.
I would like to be able to check things out with some cut-away valve covers so I could see whats going on with the engine running. Any ideas? |
Rotella is perfectly fine. It's actually my
oil of choice for mild roller cam setups, and I'll use the 15W-40 stuff for a dyno break-in. With hydraulic rollers, I like the higher viscosity anyway...
As far as the ticking, it can be perfectly normal with some cam lobe profiles. Cams will often sound like sewing machines and that's normal.
As for preload, FE's want more preload than the normal stud mounted rocker deal. My advice is to try at least a full turn of preload past zero lash and see if that helps.
