B18C4-T

So I was changing the oil pan gasket on a B16A and found these two metal pieces in my oil pan. The car was running well before this. I put it back together and drove it home and parked it. This morning I took the head apart to check the LMA thinking they looked like part of that but everything looks ok. Does anybody have any idea where these may have come from? I put a penny in the picture for a size reference.

Thank you,

the closest thing they look like to me is the "key" for the crank pully but that wouldn't make any sense. are they "broken" or flat end and smooth

Both pieces have a broken end on them, but the broken ends don't seem to fit together. They're round, not square like the keyway.

teggy!

can't really tell from the pics on my phone but I hope it isn't a ring land lol

Are these pieces aluminum or steel? If you take a close-up pic using the a macro-focus mode it will yield a better and more informative pic.

Ok, I'll try that when I get home tonight.

Thank you

It's very useful to know the material it is made of to eliminate and narrow down what it could be. Good luck to ya!

is it possable that someone has tried to destroy your engine?? ther is only 1 thing even close to those pieces and that the pin that holds the key of the distributor. other than that i canot think a single item in the engine that has pin/s like that

that part looks like steel to me.. easy to check, take a magnet to it.

They are metal pieces, the distributor keys are more square. I thought of those as well because I had a distributor lock up, but then realized that was the old engine. Here are some more pics, I'm lost on this one, the car still runs fine and doesn't make any strange noises or anything.

If they were ring lands they wouldn't be round, these look like retaining pins of some sort.

Maybe something to lock the camshafts in place when putting a timing belt on and the part broke and was never removed from the holes in the cam shaft?

Completely stumped here. I would check your oil pickup strainer. See if anything else maybe trapped.

could be something that fell in engine when valve cover is off..

DISTRIBUTOR PIN TO KEEP THE 2 TEETH IN ON AT THE END...HAD A DIZZY STUCK I NA HEAD CAUSE OF THIS THING THE CIRCLIP CAM OUT AND GOT STUCK

B18C4-T

I'll have to check and see if I still have the distributor that locked up with this motor and see if it is the pin out of that. Thanks!

are they magnetic?

can it be a part of the valve stem
maybe the valve broke on the engine and they just replaced the valves and put it back together. whats the diameter of that thing?
mught be part of a tool someone used

PyroProblem

This is what im thinking too. Maybe sometime in the past, someone had some pin punches installed through the cam holders into the cams while they were playing with the timing.

That or the distributor key pin. But IIRC, those things are fairly tight when theyre installed. Never seen one back out before, but theres a first time for everything...

I know Its been asked already, but is it MAGNETIC??

B18C4-T

They are not magnetic. I was the last person to lock the cams when I did the timing belt and nothing broke, bent but not broke.

I'm trying to decided whether to tear the motor all the way down and inspect it, or put the head back together and drive it. I have a B18 block to do an ls/vtec, but right now is a really bad time money wise.

are they both flat on one end and broken on the other?

maybe someone tried to use these to hold cams in place to loosen the crank bolt

if they are from cam holders you will see some deformity on cam rail holes since aluminum is softer.

just inspect the head and put it back together if it ran fine thenprobably nothing else there.
they look like a butt end of a drill bit
