sounds like you may know some of the Modular stuff? I have the valve cover off on drivers side, oil filler off on passangers side to see inside-crank at TDC, drivers side is a bit to the rt, say 1:00 instead of 12:00. if i bring the crank back to 10 btc it is straight up and down. is this a possibility it is off a tooth? i havent pulled the pass vc due to ac restrictions yet, but is the an accurate way to check this? getting a p0340 and all wiring and PCM tests good, runs bad and dies with cmp plugged in. is there enough clearence in the valve to piston ratio to not cause damage if this is off?
