The old valley gasket was in terrible condition, oil was pouring out both ends and the water passage on the rear of the cylinder head looked to be weeping past the gasket..

SO yes I believe I have found the leak.

Another advantage with running on LPG, the oil stays clean. I've had to do about 400 miles on petrol just recently and the oil on the dipstick is definitely dirtier now than I have ever seen it in the past and I'm 3,000 short of my next oil change.

What is it about LPG that keeps the engine clean?

lack of impurities in the fuel?

None of the additives and other crap they put in petrol to 'improve' it. It's Propane with possibly a very tiny percentage of lubricant to stop the pumps seizing up.
