Metal flakes in oil

[GTsilber]

Wow tons of info here, not what I wanted to hear but not much I can do about that. So the consensus is that if any sort of metal fragments are found in the oil, don't drive and find the source of the metal? Is there anything else I can do to try and isolate the source?

Man this sucks, but not as bad as if my engine blew. Can someone recommend an m96 mechanic in South Florida?

When you find metal bits, two things are critical: First, is there a lot of it, or just a flake or two? All engine's shed metal in small quantities, but if there is a lot of metal, there is a problem somewhere. Second, what kind of metal is it? Small amounts of non ferrous bits again is not unusual in a nearly all alloy engine, but if the bits are ferrous (can be picked up with a magnet), it is coming from something critical (cams, valve springs, oil pump, cranks shaft, etc.) which should not be ignored, particularly if it is in quantity. Running or driving the car further would not be advisable as the problem is not going to heal, and the circulating debris is eventually get to something really essential, like rod or crank bearing shells, which will put a sudden strain on your wallet.

The amount of metal is minimal, it appears to be non ferrous for the most part. The size/shape of the metal looks like broken splinter fragments from a cnc machine - little dots...you really have to look for it to notice it. I will try to get some better pics tomorrow with scale. There also appears to be some similar size plastic fragments in there as well - which is why I'm thinking it could be the timing chain or IMS bearing...I am sending my oil out for analysis tomorrow.

The car doesn't run rough, no other codes or obvious faults that I've noticed from the engine - but then again, failures appear to occur out of the blue without any warning. Any other info that I can provide to help with the diagnosis let me know...thanks for your help!

Theres a little known guy named pedro Bonilla. He's good.

Eric Baker from flat 6 gallery (or similar name) is down that way too.

If the plastic is black or brown - probably the timing chain 'ramps'
Save the debris by filtering then wash in gasoline. Dry on a white paper towel.Then you will be able to see the color of the debris.

Very interesting topic, especially for a new owner such as me and frightened witless by the AOS and IMS discussions. The car is a 3.2S on 60,000 miles.

So, the car I have has a dripping drain / sump plug so I have to swap it out with a new plug and washer, it's only done 1000 miles since the, last owner oil change and I was thinking of draining the oil and re-using it again / or just trying to swap the plug quickly without draining (is that possible?)

The question is - is it best to to drain and replace the filter and then dissect the filter and check for metal fragments in both the filter and the oil - and then re-use the oil if clean?

Does it do any good or does it just lead to more worry and more paranoia? Is it better to be happy and ignorant because the question is - what do you do if you do see a little metal - opinion here is divided.

By the way, I am swapping to a magnetic drain plug so that's feeding my paranoia in itself.

I would just use new oil. Trying to replace the plug without losing much oil will be an adventure. The oil comes out of these cars FAST! To check the oil for metal with minimum oil loss, you could remove the filter. The filter is above the sump, so the only oil you will lose is what's in the filter housing. Just to be safe use new oil.
