So, I had an oil leak that I thought was related to a replaced rear main seal.
Leading evidence: 'Replace rear main seal' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check gerotors' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I have no records of the car or any repair Aside from a car fax, I do have records of IMS being replaced when car had around 55k ..

The car has 83k miles now, does not smoke and no oil used, no knocking sounds.

Maybe at the same time ask mechanic to check the gerotors from the scavenge pumps.

Have your Tech remove the scavenge pumps and using an inspection camera, inspect the timing chains carefully while turning the engine slowly to inspect the full chains..

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Good afternoon, Everyone
So, I had an oil leak that I thought was related to a replaced rear main seal. Took it to the shop and it was diagnose as a oil pan leak, which was fix. When picking out the car the mechanic showed me some metal pieces that were in the oil pan.
They had no idea where from and suggested could have been the from years back.
I have no records of the car or any repair Aside from a car fax, I do have records of IMS being replaced when car had around 55k .. back in 2016. The car has 83k miles now, does not smoke and no oil used, no knocking sounds.
Any ideas where this is from?
To me these are big metal pieces that should never been there.
Additionally, the same shop replaced rear main, Clutch, pressure Plate, oil and coolant 2+ months ago and had not had any issues nor found any particles in oil filter.
Thanks
Daniel Rodriguez
I would do an oil analysis once you put 3 to 5K miles on the oil.
Seems odd that would be in the pan. Is it steel (magnetic) or aluminum?
Did the mechanic check the oil filter?
If the pan was never previously dropped, those pieces could have been there from the beginning. So I wouldn�t worry too much. I do like the oil analysis idea - you can try to figure out if the engine is shedding materials or not going forward.
Looks like pieces of timing chain rollers to me, not good...
Have your Tech remove the scavenge pumps and using an inspection camera, inspect the timing chains carefully while turning the engine slowly to inspect the full chains..
^^^ True should be smooth on the inside also, but still looks very concerning to me...I would want to find out where they came from ASAp...have to think on this some more...
EDIT :: possibly some shards from the tips of the Gerotors from the scavenge pumps...
Hello, Everyone
Thank you for all your feedback. Apologies thus is a 1999 911 Carrera 4. The car has 84xxx miles on it. The mechanic also mentioned those pieces could have been there for a long time, Maybe from assembly.
Just tested with a magnet, is not sticking to it. One of the pieces broke easily in my finger.
At least he was smart enough to include something in the pics to reference the size. It seems like there are a lot of "help me I.D. this" posts where you can't tell if you're looking at something the size of a basketball or the size of a BB.
I’d still like an autopsy of the oil filter.
I don’t think having an analysis on new oil helps. Ideally, the best way is successive tests at the end of each oil change to track changes and trends over.
However, once the oil has some miles on it, if there is anything amiss it should show up in the report.
Good morning,
I will put some miles in the car and do the test. Maybe at the same time ask mechanic to check the gerotors from the scavenge pumps. To at least rule that out.
Thank much
Daniel Rodriguez
I think you will need several thousand miles on the oil to get anything meaningful from an analysis. The point is to measure the accumulation of byproducts over run-time. The more miles you put on the oil, the greater the concentrations. Too early and the concentration levels will be below the measurement noise (i.e., hidden in the grass).
