Sorry about the late reply,all done now. Had to pull the whole timing cover off.
Pretty straight forward but took two days. Took the studs out of the waterpump,to get it of.Just screw them out with two nuts locked together and screw them back in. Didn't have to drop the sump,just took out the front five bolts to relieve a bit of pressure. Take notice of the Bolt locations, they are different lenghts. You must lock the idler gear together with a bolt or screwdriver of appropriate size before you remove pump gear. There is a plug located below the idler gear in the housing. Use all new o-rings and gaskets,there is only four or five. If you find yourself in this situation,it can be done but take your time. I could have saved myself three days work by tripple checking the timing marks at the start. Lot of good stuff in the forums here if you take the time to study up on stuff. Also ,thanks bods,camera probably would work if you could clean the oil of the teeth where the marks are.
Cheers everyone.
