hi guys, i got a 2000 uk turbo on a 1999 v reg,i want to take bottom end apart and get it rebored as bores are scored and new rings, do i need new crank,seals,con rods and pistons these was replaced 4,500 miles ago?????
not sure if crank will need reground?? hopefully not, last rebuild cost me over 3600 so do want be riped off again,just planing on taking block for rebore, block doesnt need any over difficult engineering other than rebore and honing many thanks guys
