I think you could be right, but in case it is something worse I would not like to recommend driving it.
Maybe one solution, since the MH is at home and he has not got a trip planned, is to take out the injectors and take them for service, re-fit, bleed the lines and try again. If Barry an do that, but I am sure there must be an agricultual travelling mechanic in his area who could drop in to do it - taking them out is only a 10 minute job.
I remember taking the injectors from my boat's 1978 Merc engine to Watsons in Wimbledon; as soon as I showed them to the boss and he said 'Oh that's an old Merc injector' I thought I am in the right 'shop here. But he had to phone me to get the pressure settings off my old engineer (ex-Merc) who udsed to service the engine - had them off the top of his head. Not many of those sorts of guys left these days.
Sorry, rambling. It's just that I appreciate that sort of expertise and want to encourage its continuation.
