Hi all, i have a 98 ford mondeo (uk spec 1.8td) with the endura de engine/head in it....and i just snapped the timin belt

... i also have an old mark 1 mondeo lyin here with the old style diesel head on it...my question is are the two heads compatible? ie. can i take the head off the old mark 1 and marry it up to the block on the newer style engine car....they look quite similar... thanks in advance for the help ! Joe
