Hi all I have a 2007 seat leon 2.0 tdi cambelt has failed ir shredded some teeth I'm pretty sure it's done some valve damage at the very least I've sourced another bkd engine out of another leon supposed to have 80k and been told it was a running car just rear end damage my question is would a head swap do the job or swap the engine for the one I've brought? I've been told I need to swap deisel pumps and injectors over from old engine to new so I don't have to have it reprogrammed is this correct or is it a straight forward swap? Thank you for any help
