my mate said he been offered a good engine freashly built by last owner so he bought it £350 and payed by cheque and the bloke let him take it before checked cleared
i took the head off and notice marks on the bores so further i delved in so much so the engine was totally stripped and all the pistons had lumps falling off them around by the rings
he was gutted not as much as the bloke who sold it though ,my mate cancelled the cheque
(hope picture works)
