LOL - yes, it is, but that was a fresh filter I put that on after I drained out all the oil and removed the Bosch one that was there.
I didn't want anything from the filter to drain back into the case after got it on the stand and turned it over.

Ok, thats going to be it for a while.
I'm off to Mt Hood for a week of skiing and hopefully when I return my cylinders will be back and I can start the assembly process.
I didn't document this as much as I had hoped to - tough to grab your phone and take photos when you are wearing nitrile gloves and covered in oil.
For assembly though, this should be much cleaner so hopefully I can do a better job at that part.
More to come in the next weeks...

Yes, and thanks for the reminder on that. I actually did measure the axial play before I disassembled the crank carrier assembly, and will also do this after the sub-assembly is put back together.
This is the tool I used (thanks again Harbor Freight). Mount it on the crank carrier, push the crankshaft all the way to the opposite direction of the flywheel and then zero the indicator.
Then pull the crank outward and measure the distance. Mine measured at 0.052.
Here is the excerpt from one of the workshop manual PDFs' I referenced earlier.

Great post and smart move going ahead with the rebuild now and doing it yourself is a great way to get even more personal with the m96. Is scoring typically more prevalent on the 456 side, if so, why?

They did this on the Cayenne V8 as well and eventually came up with a piston that was specific for the Cayenne/Panamera that used bank specific offsets. In fact, the same piston is used between the six and eight cylinder engines.

Charles, when was this change made?

The piston pins are offset in the factory pistons. It is theorized that the offset is not optimal on the bank 2 side since Porsche opted to use one piston for both sides, meaning one bank (2 in this case), doesn't have the correct offset.
