Well they reckon bad luck comes in 3s, first off my discovery td5 had a brand new cylinder head etc about 3 moths ago at great cost, it's never ran right since so I took it back to the garage that done the work to get the injector seals and other stuff checked yesterday ! On stripping out the injectors the rocker shaft has to be removed ! 2nd bolt snaps in the head ! Arrrhhh , the garage tries to talk there way round a bodge up Jodie , I say it's not napping, the head is coming off again, I've got a spare mint head so another rebuild and all new gaskets , parts etc ! Land Rover sent the parts
