Is this cam ok?

[coullstar 0]

I had decided to fit the inlet cam from my KR to the 9a and had a quick look at the cam last night.

What I found was a chip out of the case harding on one of the lobes. This was probably done when it was in my garage and I am pretty sure its now gooosed. Is it?

Yeah, that's shot - and it's more likely to have happened while it was in the previous engine. It looks like pitting more than a chip, and this would be consistant with the surrounding wear pattern.

 

I don't think you should use that again.

If you decide it is, have a word with TomB. I gave him an inlet cam last weekend. Not sure if he used it or not.

 

In my amateur opinion, that cam is useable. In formula 1 you wouldn't but providing there are no high spots then it shouldn't damage the tappet and would probably run forever.

That cam was actually once in the engine of TomB's car. I think I'll play it safe and not use it.

personally i wouldn't use it, it's not like the damage is off the profile, it's right on the end where valve spring resistance is greatest!

as said by others, I wouldn't put that in a decent engine/car. If it was a 50 quid runaround that you were only going to drive for a few months and didn't give any stick then it would probably out-live the rest of a banger, but not in a high rpm 16v that you plan on keeping!
