Anything in particular that is likely to go wrong at this mileage? It seems this engine is solid and is LPGed so does that mean it would have gone by now if it were worn or that its been looked after if its still going?
cams wear with miles and timing chains can stretch, no you probably wouldnt notice and it will keep running and running but on an engine that old i'd be looking at a top end rebuild
my 3.5 had detonation issues with the lpg and melted a piston probably worth a top end at that milage. i also have a 200tdi defender with 250k but that is running like train and i have no worries about it.
My Dad ran one to 200k but it slipped a cylinder liner, the rebuild was not worth it so it was scrapped..I think that sort of mileage is good going on the V8.
