cam timing (again)

Yes, but when I'm at TDC, and one bank has a small half-moon facing the valve cover side, what should I see on the other bank (without moving the crankshaft)? Large half-moon facing the valve cover side or small half-moon? I think large. -
Can someone please verify if this is correct for a 3.6L 3-chain motor: When the crank is set to TDC, the smaller half-moons on the ends of (say) Bank-1 cams will be relatively opposite to the half-moons on the Bank-2 cams. For example if they are oriented toward the outside on Bank-1 looking at the front (pulley end) of the motor, they should be oriented toward the inside on Bank-2 looking at the back (flywheel end) of the motor. Conversely, if the smaller half-moons are facing inward on Bank-1 viewed from the front, they should be facing outward on Bank-2 viewed from the back.

I'm confused - 3.2L Boxster-S?. The engine designation M96/03 is a 996 3.6L. See PET page below. This M96/03 short block I'm looking at appears to have the same chains and same cylinder bore diameter as my M97 3.4L (which yes, is a 3-chain). I believe only the stroke was changed when going from the 3.4L 996 to the 3.6L 996.

I am only considering the short block. All the Variocam stuff is in the heads, which I am reusing (after a refresh) from my M97. I believe the M96/03 is from 2002-2004, and would be a 3.6L. The question is whether this block would work with my 3.4L heads if there are any other complicating issues.

I snapped a rod bolt in my '07 Cayman-S (a "money shift") and I'm looking at replacement options. A local shop has a brand new short block, but its labelled "M96/03AT" - which I think is the block for an early 2000's 3.6. Would this work with my heads (M97, Variocam +)? What would be different? Is it correct to assume that a newly remanufactured factory motor would have the latest IMSB? The price makes it very compelling but not if I have to do a bunch of work arounds to get it to work. -js

For the historical record: Wheel bearing installed backwards. It matters on 997-style bearing/carriers.

I finished up a bunch of maintenance on my '07 Cayman-S and found that I now have no speedometer reading. Wheel bearing and shock R&R had required that I disconnect all the wheel speed sensors and the battery was also disconnected . On start-up I knew I would see a PSM error, but it did not go away after driving a bit. Durametric shows a P0501 error, which means no wheel speed signal. I can clear the code but it comes right back. Using the Durametric to view the individual wheel speeds, all 4 are at zero (when moving). And the CAN speed signal is zero. I checked all the sensor connectors and the connector at the ABS unit and all are good. The PSM-related fuses are good. Any thoughts on how to troubleshoot this?
