I went ahead and retorqued the head bolts. I was a bit surprised at how easily they loosened - I used only a 12" ratchet and they came right out. You certainly can't put the last 90 degrees on those bolts with a 12" ratchet, so I'm hoping maybe some improved clamping will cure the external oil leak. Fingers crossed.
The car has about 1500 miles on the T5 swap, so about 1500 miles on the spark plugs. I pulled them out, and they look like new still. If it was actually burning oil I would have expected some more soot or oily mess, but they were new looking.
I made a small adjustment to my PCV system - I shortened the larger hose by about an inch or two and cinched it up to eliminate a dip in the hose. I went ahead and zip tied it to the heater hose pipe that runs under the intake manifold, sort of mimicking the approach used on the v6 PCV for T7 cars - using heater hoses to keep the PCV hose hot. The hose itself seemed clean - which I would not expect if it was digesting a pile of oil through there.
I received the oil feed restrictor from ATP Turbo, but I am going to hold off installing it until I put a few more miles on the car and see if these changes lead to any improvement. Based on the condition of the plugs and the PCV hose, I am pretty convinced the oil burning is from the turbo and directly out the exhaust. If my retorque cures the oil leak, then I will have a choice about having that turbo rebuilt, or spending cash on a decent exhaust (it's terrible) and hoping reduced back pressure addresses Gary's oil leak scenario.
