Hello. I have a Puma Thunder which to my relief has just passed it's MOT. An advisory is a leak from the sump area, however my garage tells me they are unable to source a new 'sump pan and gasket' and that I should look for a secondhand one. No oil on my driveway so maybe a slight leak??? I have had this old girl for 18 years and I would be gutted to lose it because of this - can anyone give me some advice please? I am an old girl myself so please not too technical.
