I hope that your filter is nice and clean on the next check!

Thanks, bud! At least you seem to get the most fun out of yours.

I don't know about the history of mine, but we've only had it on the track once last year. I signed up my wife for DE.

I think you have worn thru the lead layer of some rod bearings & starting on the copper layer, that's the last layer of defense for the connecting rods. Once the rod is worn oversize it will start knocking & they are not rebuildible but they will ruin the crankshaft.

Thank you, I think you may be right. I had a hunch it was the copper alloy from the bearings. But I wasn't sure if these bearings were made of a copper alloy or not. When I can get a replacement motor for less than $4k, it's probably not worth doing anything about it now, right?

Like I said earlier, I'm probably going to drive it for another one or two k miles and check it again.

Hopefully you have some oil available to ship to Blackstone labs,..they may have some insight on the metals in your engine,.I hope its Minor wear and tear.!

Thanks, flmont. Unfortunately, I've already dropped it off at to the recycler.

I'll drive it for a few thousand miles and see what it looks like then.

Yea..I hated to state a obvious next step,..I send my oil to those guys every3-4 K miles when I change it,,.I also usally use the filter canister oil..not sure if that's smart but that's where all the metals are I assume..!

I don't see why it would be any different than the rest of the oil. How much do you have to send in and how much does it cost?

If you pull it now before the rods & then Crankshaft are junk it will be some what economical to rebuild. Or you can go the route of replacing the engine every few years & never having one that's 100%.

Roughly how much would a standard rebuild be? Just stock parts, nothing built up?

You will need at least 2 good rods & most likely a whole set of rod bearings & ARP rod bolts. A gasket set is about $300, ARP rod bolts $160, bearings $125., Rods ?? You are looking around $1,000 minimum since you want to do whatever you can while you are in there. Plus labor!!

Rings?
Are these cylinders nikasil'd, Or should they be honed?
