metal in oil pan - problem??
Hi,
Just removed my oil pan (engine is out) to respray etc and found some metal pieces in the bottom. I have attached some pictures. Can anyone diagnose what they might be and if there is a problem I should attend to while the engine is out?
thanks in advance

Re: metal in oil pan - problem??
Was the engine rebuilt? The pieces look a lot like oil galley plug/plugs that have been drilled out. Doesn't make sense that there wouldn't be new ones or there wouldn't be any pressure and a pretty big oil leak. I thought valve retainer as well, but they have a taper to them. Was it operational when you pulled it to paint?

They look like an alinement sleeve. Been too long for me to remember if the cam towers had sleeves.

Re: metal in oil pan - problem??
I believe that there are two alignment sleeves for the head to block marriage that would be about that size. There is no way they could come loose once the engine is assembled. Even if someone accidentally dropped them down an oil gallery what would cause them to be split in half?

Looks like broken rollers from a timing chain.

Re: metal in oil pan - problem??
+2 I was thinking that also after I went to bed last nite. That would explain them being split in half, and they would have easy access to the sump. Looks like it's time for new chains at a minimum, probably gears as well. You got lucky!!

Re: metal in oil pan - problem??
Are they not to thin for a broken roller?
I go for the valve retainers if it was a R16.

Re: metal in oil pan - problem??
If they were valve retainers the two "halves" would be equal in size, these are not. Could be part of the valve seal, but the metal looks to thick. Still going with chain rollers.

Yep, measured them against the timing chain and they are identical. Hopefully that is not too hard to replace

Re: metal in oil pan - problem??
Suggezt you examine the chains and identify where the broken rollers came from. Something is very wrong if chain rollers are breaking in half.

Re: metal in oil pan - problem??
thanks - what do you reckon may have broken them? How do I rotate the chain to inspect?
