I drained the oil out of an engine today and all the bit's on top of the steel in the photo came out, the holes drilled in the metal the bits are on are 5mm diameter. the largest bit of metal is 1mm thick. The engine ran pretty much fine when we drove it home ages ago. so we've stripped the engine from the gearbox to try and see what could be the problem, but from what we can see there isn't one. I think the head has been off/ changed in the past, but not sure if the GB has be split.

 

It's a 998 from a 1982 car. 

I know it's not much to go by but does anyone have any ideas what it could be from or where to look in the engine? Could it just have been a bit of metal accidentally dropped in and missed?

Have you got a magnetic sump plug fitted? If so, was any of this stuck to it? I'm trying to find out if it's steel or alloy?

 

Rip your oil filter apart and have a look in there as well.

sorry forgot to say it's magnetic

Ok, so it's definitely steel then, so we can rule out the alloy gearbox casing?

yep.

As mentioned, I would check the contents of your oil filter to see what's inside, this will give you a better idea of what other sizes of steel and how much has made it's way this far. Use a magnet and rub it over the filter paper. If it's made it's way this far then prepare yourself for a thorough check of everything!

 

Or you could wash and scrub the oil filter paper element in a glass bowl with some white spirit or petrol and an old tooth brush.

Any other ideas? Will have a look in the filter in a minute.

It looks more like bits of gearbox rather than anything from the engine, but that's really just a guess.

 

If you can't find what the debris is you might consider a precautionary gearbox strip & rebuild.

 

Also take off the big end and main bearing caps and check for damage to the crank. Fit a new oil pump and if there is any damage to the big-end or main journals remove the cam and check the cam bearings.

 

It is worth checking everything whilst the engine is split from the gearbox.

 

Also check/change the diff pin (look at the photos on the other current thread!).

 

Once it is all done you can be confident that it will last a long time.

Could it be bits of crashed gears? Someone in past having trouble changing or trying to change down into first while moving?

Cheers guy's, Pretty sure it's not gears as they all look in good condition, it looks to be more flat steel like a locking tab and the bits pictured have just been munched up. will check it over though.
