Adding more than max oil level

Did he put a new oil pump in? That's one of those details that first time builders miss...

Had a friend years ago that drag raced a 427 big block Camaro. Mid season he would drop the pan and change out the crank and rod bearings to freshen it up. Did this for years with no issues. The one time he did his mid season. He put in the wrong size bearings. The bearings was 0.010" over. Start the car up and had low oil pressure. Couldn't figure out why. Ran the rest of the season. Said that was the best that motor has every run. End of season tear down and rebuild. That's when he found the over size bearings.

After talking to him for a little while we both agreed it seems far too low. We will pull the engine within the next few weeks and check for damage/issues. Better than blowing up a 20-25k engine. We were just hoping it could've been literally anything other than internal, so much for being optimistic

Wish in one hand, sh1t in the other, and see which fills up first.

Not good. Looks like machining chips.

Wonder where that long piece came from.

Maybe that engine was only built to handle 1000hp once. Or 300ish hp 3 or 4 times...

Kinda like the harbor freight tools of motor builds.

Looks like part of an oil ring.

The worst of both worlds then, that sucks man.

GL to you however you decide to proceed. LS swaps are getting easier by the day.

Regardless, pls keep us posted.

Ugg, not good. Good luck to him. Hope it is nothing expensive. Oil cooler will need to be replaced and all the oil lines cleaned.
