help! can't seem to find correct timing sequence on '93 960 wagon...old timing belt frayed, but not broken, found engine to be out of sync w/ any diagrams and instructions i currently possess. have tried all i know without doin damage to the old girl, to no avail. seems crank and cam pulleys are out of sync, and according to the volvo manual, if i put everything back as instructed, i can't even make one revolution by hand w/o feelin some resistance. i have heard after a "professional" rebuild, this is quite common, as they don't index the crank, or cam pulleys correctly. as long as it runs, they send u on ur way,. and that's that...any advice or tutoring gladly accepted! thx.
