Yeah i think the body will fall off way before the chassis gets too bad.:hysterically_laughi just got a disco for the same thing, its a 1993 and comes in green and rust lol. but still strong enough for the job.

you may even find that once u have repaired the leak/replace faulty unit, you can be finding traces of oil in the system for months, just keep flushing every couple of weeks to clean it out. can be a b**** to really clean as oil can linger anywhere in the system. Hope you get it sorted soon. Rik
