Life is a grind...

A "cam grinder" or good machinist could build up the lobe with a bead of weld and then mill it down, assuming that the chip is not too big. You would have to magnaflux the cam to check for cracks. Check around local machinists / welders.

I sell used cams in good shape for under $100. Just an option, I can't imagine a welder doing it for less than a couple hundred.

Find a replacement cam!!
Camshafts are works of art in that the surface of the lobes is hardened.
Almost every weld is going to have gas pockes created by the heating of the metal, when the surface is "re-ground" these pockets will be exposed. The other thing to keep in mind is the weld or "fill material" will almost certainly be a different alloy than the original cam, making for uneven wear.

The only time I would even consider having a cam weld repaired would be on a turo Offy or something of the sort where a replacement camshaft would be near $8K. I'll ask around a few circles for a cam. I tracked down an exhaust cam not too long ago for less than $500.

I can't see any reason that you can't have the shaft refurbished...I have had the same process done to several spindles of the CNC grinders that are used to manufacture camshafts, and they have run for years 24/7 without fail well within tolerance.(and I am having my crankshaft welded back to size currently) I could recommend a shop here in ON if you like...

Hope yu get it back on the road soon

has anyone tried any of their 944 cams? The price certainly isn't too bad.

Looks like they will weld lobes for $50 each.

who here doesn't leak oil??

If it were me, I'd give that paeco place a call and see if they could fix it, and probably for alot less than trying to source another used one.

You sure you ordered the right one? They are asking $600 for a cam for a 944 S.

Sealing circle?

It is not chipped on a lobe? AND it is not chipped in a load bearing area?

If it is just where an oil seal rides......Cold Bond and a file.

Post a pic so that I can be sure what you are talking about.

If no pic, describe your defective shaft...............Boy, that sounds weird!

Seriously man, when you start a thread give us some bloody information.
Pictures would also be a good idea. If you just say "chipped camshaft" it could be a lot of different things. I don't know if you think it is fun to just make a 1 line post and waste everybody's time or what. Then you continue to confuse the issue "I bought a new one" followed by "it would be nice to just get this one fixed"...? Gonna put in 2 intake cams are we? That said, its not until the 4th post by you that you even mention it is an S, so it has 2 cams, so people offering up cams are probably offering 8V cams. That also makes the cams more rare and more expensive, making pricing advice irrelevant if people don't know it is a bloody 16V motor.
