M20 Cam Scoring

[SLEEPYDUB]

I bought this cam off of a member. He neglected to tell me about the scoring until after I paid him. Is this common? Can they be polished out?

That cam is trash and who ever it was screwed you over

[SkiFree]

X2, If I was offered that as a cam core I would have laughed, loudly, and rudely. You cannot "polish out" journal lobes that bad.

If you paid for that, I would politely ask for a refund on the part at least (and eat the shipping). No self-respecting enthusiast would sell that to another enthusiast.

If he refuses, I'm sure the mods will not take kindly to it.

Nice paperweight you got there.

[TobyB]

Oh, you can use it....
...if you had to, and there wasn't another one anywhere around. Ever.

It won't be ideal, though.

The little bit of a lobe that I can see looks even less exciting...

Great core for a regrind?

[Kershaw]

If they don't refund you, please post their name. I don't want to buy items from them.

The scored journal shown is one that rotates in the cylinder head, not a cam lobe that would get reshaped during a regrind.

As Toby mentioned, this is a good cam for using when you are are on the side of a road in a third world country and the cam in your motor is in two pieces. Or three pieces.

Otherwise, the cam is junk and the seller is either ignorant or a swindler.

Whoa totally missed that. Thanks for the correction!

May be a good candidate for a lamp
