I'm assuming that cam timing is ok and the chain isn't stretched (you have checked this, right?).
Or.... I hate to go here, but... what's the oil consumption rate? A good 60x engine should be 4000 miles per quart or better.

Cam timing and IP were spot on...the FSM says to put the motor at 15 deg. ATDC when pulling the IP but I don't see how you can do this without pulling the valve cover to see if it's the exhaust or the compression stroke...so needless to say I saw that the cam and crank were lined up when I went past TDC.
Last time I checked, before I rebuilt the turbo it was about 1 quart at about 2K miles...but I drive it like I stole it and at about 85mph on the highway.
I can't help but lean toward the delivery valves and one bad injector. I'm almost positive it had this miss/shake behavior before I replaced with the bosio nozzles several thousand miles ago.
