2 hours to get it ready to demate from gearbox, then best part of 3 hrs to separate from the left hand gearbox alignment dowel. It was stuck fast in block and g'box. Ended up with one in the gearbox, and one left in the block
about 4 hrs to put new one in including new timing belt, clutch, flywheel and an oil change. Did it over 3 evenings as i had to make a new alignment dowel.
