I am not a mechanic by any means....but I did stay at the best western!!!

#2 sounds like you need a seal for the turbo "U" joint, mine did the same thing and had it replaced and the squeal will quiet down.
The stumbling upon start up could be glow plugs are old and need replacing, replacing your fuel filters wouldnt hurt either.
Blue smoke? I have no clue...maybe unburned fuel from the starting?? Not sure
The other thing about the miss when you open the fuel line, could be you need to rebuild that injector..maybe find a JY one or two and try replacing to see if that will help...if any of my info is incorrect...forum members feel free to correct me! I am still learning too

The motor rocking could very well be that you need motor mounts

Compounding and buffing and polishing does wonders for the paint
Mine was all chalky, and just compounding and meguires polish cleaner wax did a good enough job to make it shine again! I am in florida so the sun does a lot of damage to paint here if you dont have a garage
