That squeek could be one or 2 cam lobes wiping and or the roller lifters.

I'd pull the intake, and pull all the roller lifters out and inspect them carefully.

That did happen to me one time on a hydraulic roller cam, (600 miles away from home). annoying squeek at low rpm and low loads. You could change the quality of the squeek by loosening or tightening on the bad lifter.....that was my clue.

If you catch it soon, no harm-no foul. Just get a new cam and new lifter and try again. "It happens".

You might preheat the oil prior to initial start up next time? Couldn't hurt. But I think what was meant by not doing that 20 min break in was that that is not at all needed. Just drive the car for a break in.

Crane made a good general statement about the high spring pressures and idle rpms. Seems logical.

A Crane tech told me a while back that you cannot run a solid roller cam on the street. I said, Wha???!!!!!
Then how did I just run my Lunati circle track cam on the street for the last 2 years? Shows you what I know.. <shrug>

I think what they mean to say is, "A .600+ lift solid roller cam set up won't last near as long as a mild .500" lift hydraulic set up on the street." Well, that's my translation.

Really, the 1st that I read your post, I thought back right to my valve train squeek and cam lobe-lifter wipe.

I understand why you don't want to let a roller -or any other- engine idle for too long a time frame, but I haven't seen it kill off lifters, either. Our race car routinely idles for a few minutes at a stretch at 2100 rpm with restrictors, and the one thing that never shats out on us is the lifters.

On a related note, I don't know if it's practical for a car with a wet sump, but we open up the lifter bores about .001 on this car to improve oiling, and after a year the lifters look nearly new.

So what you spun a cam bearing? Doesn't sound like you spun a main.
