is there any was I can tell if my diesel engine is the original one. Original Reg. is NWD564M (now on an Irish ZV number Plate). On plate on the drivers side of seat it says its a petrol. 1st reg in Sept 1973, I bought it in August 2012.
Thanks for the info, my chassis no. is 901#### and my engine no. is 9064#### so I guess I have a bit of both. Previous owner ran it on a mix of diesel and veg oil so at least its cheaper than petrol. Thanks again for the replies.
