Everyone:
Anyone that can help please let me know, I really am in dire straights on this one. Here is the situation:
I have my Cobra at the shop getting the cam and intake replaced and, the advance re-set (there was none), and the heads worked on a bit. They have just spent 20 hours pulling the whole thing apart, and then replacing the cam and intake and putting back together. Yesterday they did a 20 minute or so break in period on the new cam and saw no problems. This morning though, when they pulled the
oil pan to check the cam, problems.
There is scarring along the top of one of the front cam lobes and the lifter it is hitting also has some nicks in it, and looks like it is going concave from the slightly convex shape they normally have. When I called the cam shop, they said the cam was not making it thru break in (that the lifter was not rotating) and should be pulled out and sent back to them so they can try to figure out what happened. I am having another guy in town look at it as well to try to measure the taper on the cam and the radius on the lifter.
So then the mechanic and I looked at the old cam and lfiter. It looked like the lifter from the same area of the engine was not rotating either. So here are my questions:
1) Do you all agree the cam is shot and needs to be taken out?
2) What do you think happened? If it was that the lifter wasnt rotating, how do I make sure it is before ruining another cam?
3) How do I make certain this doesnt happen again?
