With my camera fully charged and my engine taken apart I have a big update with lots of pics.
Half of my engine torn down
Piston rings need replacing
The IMS bearing is really bad... (lots of play)
other crank case in the hot tank
The following is not my car stuff....... but I thought it would be nice to share..
Jason showed me the difference between cayman s head vs 996 3.4L head
cayman s
3.4L 996
intake ports shaved
crank and bearing case
shaved down to the copper
Transmission rebuild
2nd gear pop out look...

Thanks for actually taking out the *****, unlike most that just turn them and check it for play. Based on the condition of a few, looks like a rebuild was inevitable soon anyways.

Anyway, yeh looks like the trans was about to self destruct which would have upped your costs even more. Curious, what kind of estimate are they giving you for the total bill?
Keep the pics coming. Awesome job!
On a side note, looks like another DR IMSB failure was coming. Thought these were rare but it seems theres been a few posted recently of the "low risk" engines.

So the chain rails were really grooved down. And the IMSB had a lot of play! What did the bearing itself look like?

There were no obvious signs of what the intermix problem could have been. The heads were sent out to be pressure tested and resurfaced. I will find out tomorrow or Thursday when the heads come back from the machine shop.
