Mystery sludge

[Kevin Johnson]

Briefly, it appears that a decomposition product of a typical moly additive is both ferromagnetic and has a tan to brown appearance. This would be consistent with the additive fallout comment.

Not a lot you can do with OEM block at those power levels on dirt but rules are rules.Possibly splayed mains and partial fill with oil cooler since your on e85.

It's more of "my budget" than rules...Or rules of the household trump the track rules

I’ve seen sludge like that after using royal purple but not thick and not as much but this was only with 15 runs down the track.I just quit using it and it went away.

On a side note here, and I know it’s out of your price range for this type of racing unless you find a used one, but your center main ware issue is from needing a 8 counter weight crank due to your hp and rpm level stuffed in a factory block.

Been there those household rules are a lot tougher to slide by than a tech inspector at the track,lol
