Take a look at these cams...
Goodhart, I'm not trying to diss the product you sold me. I just don't know enough to know if I should be concerned about this.
Look at the main journals on the cam, they are a bit scored, enough so that I can just barely feel it with my fingernail.
Are these okay to run? I suspect its not a big deal but I dont want to have to rip these out again, or damage my rebuilt head.
*note: the little stringy things are just threads from the rag I was holding it with, not metal shavings or anything.

If you can feel it with your fingernail I wouldn't run them.

Re: Take a look at these cams...
do you have anything or a machine shop that could check if they're close to spec? (and maybe polish them)

Those journals look pretty beat.

Re: Take a look at these cams...
Can machine shops even do much about it? if you take much material off, they're just unusable, aren't they? Since there aren't any bearings for the cam journals, the cam just directly contacts the head.

Re: Take a look at these cams...
I would take them to a machine shop, have them polish them up and see if they are still with in spec. It would be just like polishing a crank.

Re: Take a look at these cams...
Wow I finally got a chance to see these pics here at home. Those pics sure don't do them any justice!! lol They didn't seem to look quite that bad in person.
But, like I said in my PM, let me know how you end up and we'll work something out. I'm not out to rip anyone off.

Re: Take a look at these cams...
Thanks dude. I have no beef with Mike at the moment, it sounds like he is going to work this out with me. Sweet!

Re: Take a look at these cams...
What cams are they? And about how many miles with what oil, and how often it was changed? They look like a used cam.

Re: Take a look at these cams...
the cam lobes look great, but the main journals aren't so good... makes me think the cam caps were improperly torqued or installed wrong or something?

Re: Take a look at these cams...
What about the grooves you could feel with a finger? Those cant be cleaned up without actually taking material off.

Re: Take a look at these cams...
these are stock cams  Polishing takes material off, just a very small amount. I could barely feel the grooves with my fingernail before, and now they're all but gone.
