My 2001 1.9d has a poorly engine ( slipped timing belt ) it starts and runs like a bag of nails, but i feel the best route will be to fit another engine, can someone confirm the same engine is fitted to a mk2 punto 1.9d of the same year? the engines look the same and are both 8v non turbo, but the punto seems to have a slightly different rocker and inlet setup? would these just be interchangable?
