My MH is on a 2005 Ducatto 2.8 JTD. When going through its Roadworthiness Test (= UK DOE) the tester said its sump was so badly rusted and should be replaced asap. Back in March when getting the oil changed the mechanic used a machine to suck out the old oil as he was afraid to open the sump plug incase the whole lot came away On inspection it appears it is rusting from beneath the paint, no scrapes or scratched just the paint bubbling. (see pic) It must have been made from sh1te metal first day. Has anyone else come across a sump rusting away after only 10 years, it's never been on a salted road, hasn't seen very many wet roads either.
