since i had engine rebuilt at D&s motorsport the car has only done 25 miles i bought the engine off them and it came with receipts from jamsport, D&s rebuilt the engine but didnt replace the piper cam as i was told it was in good condition, since i got the car back it has had a top end rattle, D&s say it sounds like that because its a piper cam. i tell him it must be worn! who is right? lifters were replaced.

he says he will check the cam for me but it will be a week or so cause hes flat out at the minute
