Brass found in my oil filter. (pics)

ERStettin · 03-21-2006, 04:30 PM

Pulled my engine for a check up and brought it up to Lorens place (Grove Machine). He told me yesterday that he found some brass in my oil filter. Any guesses why?

Here is a set of #2,4,7 rod bearings that were bad. There is some heat hazing on the crank journals showing (magnafluxed it) for these rod bearings and all the main bearings are good. The #1, 3, 5, 6, and 8 rod bearings are fine.

I have provided a picture showing both sides of the bearings. The jury is still out on what happened but after Loren checks some stuff, we should know for sure.

Guess that's why most people tear down race engines on a regular basis, huh?

Glad you found it in time!

Detonation is the primary suspect now. The next bearings used will be coated.

what bearings are you using???

That's a Clevite bearing. Tri-Metal.
(searched the part number

)

could it be to tight of tolerance on those?
did they check the big end of the rod for roundness?

Is the bearing the "H" bearing or the street type bearing, the H is the race bearing!!
