New to the ls motors, bought the car a few months ago. Did my first oil change on the motor since I've had it and found five metal chunks stuck to the drain plug. Any idea what they're from. No knocks and seems to run fine. Car did not come with nor have i installed an oil pressure gauge yet.

what car is it? Should have an Oil Pressure guage on the dash, that does not look good.

the motor is in a 240sx thus no oil pressure gauge set up on it yet. was bought from enjuku racing in february. We were told its a stock pull out from an 01 camaro.

Pull the valve covers and check all the springs. Kind of looks like a valve lock.

Looks like a rough situation. Did you install an oil pressure gauge yet?

Looks like a valve guide actually....or parts of one anyways.

have had a busy weekend with no time to check out anything yet. will update when i find something. I'm not gonna install a gauge on it right now. I plan on finding whats broken before i cause any more damage.

That does not look good. Please keep us posted on what you find and how this may have happened.

I actually would tend to agree with this more than the lock that I previously thought it might be. Was looking on my phone but on the computer I don't see any ridges like a lock would have.

Valve guides are bronze, and would not me magnetic.

That is not a valve lock either. C'mon guys, if he had a missing/destroyed valve guide or valve locks, the car would not be running.

The only non-critical part could possibly be a piston skirt, which could indicate detonation of some sort. Do you get any pinging?

Im just having a hard time with it because the biggest piece seems to have a curv to it so that eliminates a guide so maybe a bearing shredded?

Turn it 6 grand in your driveway, and i bet you find out what it was.
sorry, i know that wasnt helpful

stock GM valve guides are powder metal .pull the valve covers ,remove the rockers and inspect for loose trunnion bearings or broken valve springs.
