My treasured Rover 75 blew her CH gasket and literally frazzled her engine so I thought I might as well get another from a scrapyard. I found one allegedly from a 35,000 mile car, to be supplied with NEW CH gasket, pressure tested, new water pump and belts, 2 month warranty.

I bought it and had it shipped to Bulgaria where I live. Got it put in and having checked liquids every day was shocked to find increasing amounts of clag in the header tank.

I assumed this may have been in the system from the previous disaster, but as the days went by it did not clear. I flagged it up to the supplier immediately and within the warranty period and several emails passed between us.

I had exploratory work done to establish the cause of the problem and all pointed to CH gasket problems. I told the supplier and was offered a new gasket and stretch bolts but they have refused to pay the £317 cost of having the work done.

How can I force them to pay up since this engine was not as advertised? In fact when I first saw it I saw no evidence of traces left by work being done on it. Surely the offer of a new gasket and bolts FOC is an admission of liability?
