The one overriding thing with the Rover V8's is the cooling system and the coolant.
Get that right and it's a reliable lump as far as general running goes. You're always going to get component failures, but so far we haven't had any main engine parts fail, but we have fitted better spark plugs and a set of decent leads.
Philip's V8 that he bought last year had horrendous corrosion of the cooling system, the steel pipes for the heater were rusted through, not just one, we had to replace three of them, they were solidly crusted with rust inside.
That means the liner outers are also rusty, so we are expecting liner troubles at some point as the rust will expand and force the liner/block joint apart.
Most folks don't realise what rust can do in the right conditions. We've just replaced some framing on our 4-wheel trailer, the welds that held it on to the main frame had been broken by the rust expanding between the frame and the chassis.
Ours is approaching 60K on the new engine, and it's a nice lump to drive, no water loss, original radiator (148k miles) but we do run genuine LR OAT coolant in it and always have.
LPG doesn't make a lot of difference, except that the Motronic system doesn't adjust foir vapour flow against hard injection by petrol, so there's a bit of faffing about occasionally, but when we need it to pull the big trailer (next two weekends) it is there and always does the job.
I'd like to get the LPG inlet pipes to the manifold/plenum adjusted for length, as at present some are longer than others, but apart from that it's a great tool.
