Cam caps are not really interchangeable. They are rough machined , bolted to the head then line bored.

However you can hand fit a used cap to get you going again.

The cam journal will need polished but don't be too worried about removing scratches that go around the journal. Removing all the scratches so will only make it smaller, just get rid of anything that looks like it will tear metal as it rotates.

Get another cap, bolt it to the head, use a straight edge across 2 good bearing caps, ( with the replaced one in the middle ) . If the cap isn't too far above or below, precede to the next steps.

Install the install the cam ( but not the chain or rockers ) and use plasti gauge on the bearings to get an idea of clearance. If the replacement cap is too large / small of a clearance, try another cap. Once you have settled on a cap, remove the cam, replace the cap then look at the parting line to see if there is a ledge. If so , try another cap. Once you have found the best compromise, file the legs to reduce clearance, shim to increase, chamfer the parting line edge if there is a ledge.

When finished, don't run the car at high speeds for say 500 miles any high sport have a chance to flatten out. Oil pressure at idle might be slightly lower of the clearance is large.


The only other way to fix this is to replace the head or have a machine shop bore that cap for a bearing insert. ( looks like a connecting rod bearing ) . Doing the patch up is worth the risk.
