have taken the oil pump to bits off my cally turbo motor to fit nylon pressure release vlave and steel oil pump gears.
used a impact driver as suggested by someone on mig, many thanks, very easy to use, except one of the bolts that keeps the backing bit on has mangled the head of it.
can you get these bolts from anywhere? vauxhall etc? or just a local wholesaler of random bols and washers?
