So, got the timing belt cover off, front passenger tire off and sprayed brake clean everywhere and it appears that the leak is from the crankshaft seal. I see how to align the timing belt to the notches on the cover and making sure it aligns down below at the crankshaft. It looks straightforward to ...

well my linkage had also fallen apart and the dealer wanted $500+ to replace the linkage. I was able to get the kit for $10 and spent about 2 hours getting it fully installed and now it's as tight as can be and it's a joy to drive in this mode. Well worth it.

final update on this thread. After replacing gas cap and after the HD magnets on the bottom of the gas tank were installed I don't experience any symptoms anymore. It still has the CEL on for the 2900 code but I've learned to just live with it. Annoying but the truck runs great.

yes, the fluid level is full. It's a mystery to me.

i found an AW71 which should fit my volvo. thank you.
