Camshaft Damage question

[flank]

I am currently taking the engine apart....
Here is a pic of the exhaust camshaft:


According to the Haynes manual, I could have it reground..... but in this state, is it really necessary ?
Also how did this happened since all the other lobes are smooth and fine. ?!?

Thanks

Almost looks like a casting issue. To be honest, I'd ignore it. That part of the cam isn't in contact with the bucket at all, so it's a non issue.

grind the area thats damaged to remove rough spots .use a dremil or something similar.this will hopefully stop it from sheding any more material

Exactly, the "heel" of a camshaft is the area of the cam where the valve lash is measured = No Contact with the shim/bucket.

I love it when you say camshafts. Whisper it to me.... http://www.youtube.com/watch?v=xp1TchA7qDQ

If you grind it, it will pretty much ruin any chance of future correct valve adjustment. BTdubs.

Unless you use a mill and make a note of exactly how much you grind off. I would leave it be. But hey! don't let me stop you from doing something you want!
