Okay, yes pain in the ass. Had to disconnect EGR at bottom to allow top to have room to come off plenum. I took the top shelf out which gave lots of room. Many of the nuts/bolts that had to come off were done blind, totally hidden.
When I tried to get the section from nicoclub, it wouldn’t come up (the EI section) Didnt have to drain any coolant though. ??
Now that it is back together, I have a hiss or suction sound on the backside on the plenum along with a coolant smell (related to the hiss). Hopefully I wont have to take everything back out to find it.
I dont recommend doing plugs unless you want your hands diced and sliced. And I have small hands.
