Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Coverage and how to read this overview
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.

I was pulling a motor (that I know has an LN Bearing) and noticed numbers stamped in the block behind the sump (see pic).
Anyone know what these are there?
Guessing the motor had extensive work at some point. It is not an AT engine.
Was this done at the factory? I have seen many of these engines and this is the first time I've ever seen something stamped there. For a while when I was much dumber, I used to use that spot as a jack point...
Interesting, never seen them before in any other 996 engine that I have worked on. This is the first 2001 that I have worked on, maybe it started at that point, although the AT engine with the big 997 bearing that is in my car now (made well after 2001) doesn't have them.
Most of the time it takes some forensic cleaning to be able to see and read the numbers, it doesn't take much dirt and grime to hide them, but I have never seen any castings without them...
Yea, a dry corrosion is what will hide the numbers the most, you will think they are not there, then start cleaning and lightly sanding and they will appear like magic...lol
