cam replacement question

[strad]

There's a good possibility that I will need to replace my cam. Lobes are fine, but somehow the dowel pin hole has gotten enlarged, or at any rate there is play between the cam drive wheel and the cam (back and forth, total about half a tooth). I do not know the mechanism by which this occurred. The question is, can I get away without replacing rockers. Iirc there are no visible problems with the current lobes or rockers, but they've obviously been together for 165k miles now. The new cam will be a stock replacement, and the only one I've seen is Febi. Is that a good choice, or what should I be doing?

The head had a valve job and new guides just 5k ago, and currently has no other problems besides the one above, at least that I'm aware of.

edit: forgot to mention that the first step I'm taking is to get a new cam wheel (with new dowel pin) and see if it fits properly. I figure if a new one has the same issue, then the problem has to be the cam.

you shouldnt have to replace the rockers

Cam and rockers wear together. Plus too, new rockers are stronger than the stock.

replace the rockers. not only do the pads wear, but the aluminum fatigues over time. Basically an aluminum rocker has a limited number of cycles it can go through before it breaks - and a used rocker will have gone through a good chunk of that.

Well here's hoping that the new cam wheel and dowel pin will solve the play issue lol.

Damn this excursion is getting expensive. We're already at 360 in head parts if I do rockers and cam, and that's assuming I don't find something terribly off with eccentrics or rocker shafts. And then there's a head gasket set.

Does anybody have any advice on how to check cam bearing to cam journal clearance?

Well the new cam wheel did solve the problem. So we're good for now without buying a bunch of new stuff for the head.
