Should I be Concerned? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I found these pieces in my oil pump pick up screen. The engine is a 75? 454 and ran great when removed. My plan was to remove reseal and reinstall without a rebuild. I checked the timing gears and oil pump but did not see anything broken. What else should I be looking for or is this possibly from a past event?

Plastic (nylon) or metal?
Check with a magnet.
Nylon could be from old timing chain.
I had an oil pickup on a 396 that was half clogged with nylon once. Replaced it with no problems.

Definitely metal

If it ran good just ignore that stuff.
Oil pumps won’t let anything big go thru without exploding!

Yup if the oil pump didn't go sideways - you are probably just fine. Put her back together and run it.

My bet is they are pieces of a broken crank gear. I have done it myself and have watched others do it. Break the gear with a large chisel and hammer, Two good whacks and wha la.

The process is to remove the gear for a chain/gear replacement. Proper way is use a puller

Problem is, how they break. I have never lost a piece but could be possible. Seems heavy to get in the screen but floating in oil, who knows.

I could be very wrong
