Volvo S60R timing marks issue

Car has 249k miles - it dies and will not restart, and has loss of compression issue. After a lot of other things eliminated, came down to the timing marks being misaligned. Before reset - 25# compresssion, after reset, 135# compression. It was suggested to me that I may have a cracked crank gear - I looked it over, and you get to see about half of it - but attempting to pull it off with my light weight puller yielded no movement, if it spun, it doesn't make sense that I couldn't then pull it off easily. I'm leaning toward it being installed incorrectly at factory, and never noticed due to the VVT soaking up most of the 20 degrees of retard on the engine, and it finally (at 249k) decided that it was far enough out of spec to trip out the cam codes.

FINAL OUTCOME: The final solution on this engine was that the crank gear had stripped and spun approximately 72 degrees - causing the crank position sensors and the cam sensors to disagree and shut the motor down (a blessing that kept pistons from slapping valves) - The crank pulley spinning some on the crankshaft caused the crank pulley to be off time - physically re-timing the motor allowed it to run for a very short time, then stripped again - which in turn showed me that it was the crank pulley moving.
Ultimately, after thinking all the electronic things being wrong (bad wire, bad CCM, etc) it turned out to be an actual mechanical failure. The car runs fine and is back in daily service. Still pulls very strong for a quarter-million miler.

This video was shot on my Blackberry KeyOne, so apologies for jitter, sound level, or anything else you want to gripe at on it.

THANK YOU FOR WATCHING!
