oil pump sprocket question

[lowandsleekDSM]

Ok im currently doing my timing belt and ive done everything expect when i rotate the crank to check the belt the oil pump sprocket is only matching up with the rest of the timing marks every 3 turns of the crank ( i rotated the crank 6 times and on the 3rd and 6th time the timing marks on the oil pump sprocket and everything else lined up) is this going to be a problem? or is it suppose to do this? im thinking its just because of the smaller sprocket...and the turning ratio i guess in relation to the crank sprocket and all the other sprockets possibly?

Oil sprocket is ratioed 2:/1 to the crank sprocket due to the balancer behind that sprocket (if it's still in the motor, or have you done the BS elimination?).

This is why, on a belt install, that you swing the crankshaft clockwise 6 full revs with the 1/2" socket wrench in the middle of the crank sprocket (and it helps to turn easier if the sparkplugs are removed so that the compression doesn't bog things down)

For after the 6th rev, all markings (cams, crank sprocket and balancer sprockets) should align up back to their respective marks where they belong when you put the belt in.

Ok then i should be good then...because on the 6th or so turn, the oil pump sprocket and everything else match up perfectly. Geez hope everything works out with the timing belt ive had so much trouble with this car in the past few months...well soon find out. Thanx for the info!
