Big problem with ims, I think

Nothing to be ashamed of. It's not rocket science, but there is some alchemy/dark arts involved; taking it to someone who knows the tricks is a LOT faster than leaving it disassembled until you accumulate the knowledge you need to put it back together with some expectation of it running.
I could use a LOT of professional help, but that's a story for RLOT.

I ordered new water pump , aos, oil pressure unit and plugs while I have the engine out. Anything else I should do while motor is out?
Clutch , throw out bearing , flywheel , pressure plate and rms only has 2000 miles on it.

The mechanic called and told me he couldn't find anything wrong with the motor so he installed my eps Ims bearing and told me I could come pick it up. I can't figure out why I wasn't reading any compression on number six cylinder. May be my gauge is bad. Now I'll have to figure out why it wouldn't start.

I don't know how confident you are with your shop but if you want to do some sanity checks yourself before reinstalling the engine, this is a great tool
Just remove all the spark plugs and attach the tool to the cyl #1 spark plug hole. Turn the engine (clockwise only) until you hear the whistle. The sound should stop close to the tdc mark on the crank pulley. Then put the tool in cyl 6 and repeat. The tdc of #6 should be at 120 degrees after #1. Follow the firing order(1-6-2-4-3-5) to check the remaining cylinders every 120 degrees.
This test will confirm you have compression in the cylinders and the timing is in general correct.
You can also remove the green cam plugs to visually check if the timing is perfect on both banks. You will need to replace those with new plugs afterwards.

Ok, I got the motor back in after having the ims replaced and it fired right up. But there is a knocking sound coming from the bank 1 side that wasn't there before and the check engine light came on. The code that came up was p1340 bank 1 timing out timing sensor. What tha hell? Is that going to be expensive to fix?

Pop out the green plugs for the exhaust and Inlet cam on Bank 1 - do a visual check of timing at TDC.

No, it's the bank 1 timing, or the variocam actuator. The sensors have their own codes. It's likely the former given the work done on it hence Schnell's suggestion of checking the cams for proper timing.

Lots of missing puzzle pieces here..
Was the old bearing failing?
Were the cams and crank locked properly during the IMSR procedure?
This whole scenario seems a little too haphazard for my liking. Lots of things could have happened here.

It would not start and it sounded like it had jumped time while it was turning over. That's why I dropped the engine. The Indy couldn't find any problems with the timing so he installed the new Ims and I reinstalled the engine and it started right up but is making a slight knocking sound from bank 1 side and engine code was p1340.
