I have the oil pump cover re-installed along with the Crank pulleys. Still have to put the rest back together. I assume the vaseline pack is an alternative for priming?The gears don't need washing, leave them alone. Pack with vaseline before re-assembly.
Your turbo doesn't have a crankshaft position sensor, though it seems to have the shutter wheel for one.
Put the seal back in with a whisper-thin coat of RTV sealant on the outside.
