Hi, I decided to strip a TD5 defender engine after finding oil in the water. Oil cooler definitely needs replacing but not sure about the marks on the block? Do I need a replacement block?
Machining isn't recommended on TD5 engines, so rebores, skimming, crank regrinds and the like should be approached with caution. However, this guy claims to have skimmed a TD5 head successfully: Web Rover So maybe you can . . .
