good advice, thought I'd have to be towed a couple of times there, but she came through!!!
The issue was heat. As soon as she got properly hot (now I know what you mean about cooking your left foot) she started to mis fire. In fact we had to stop by the side of the road for half an hour to let her cool because hills were becoming impossible. Then, as soon as she had cooled down she sounded fine again and went on until getting hot again, by which time we pulled into the field at Cobaton.
Just about to leave and I thought I'd check the engine and water levels. Water right to the top. Engine oil right to the mark, but above this were a few inches of white froth. Head ghasket thought I? So I let a little oil out of the drain plug to see what the situation was, and the oil was clean, no water. Maybe the froth is just condensation as this is the first run she has had for many years. Right then, head off, fingers crossed.
On the way back same story as on the way. A lengthy stop to cool down about half way and ran poorly when hot. When I thankfully got back to the yard she wouldn't start again, the starter wouldn't even turn like a connection was lost. An hour and a half of cooling later and she started right up and drove nicley again, engine sounding smooth.
At least the exhaust bandage held out!!
I recon possibly the condenser or vapour lock? Definitely heat related.
I had left the cover off the fluid flywheel for the trip and the heat coming from there also cooked the left leg. Tomorrow I'll check all levels and see what has happened, if anything.
Cheers for now,
a very fatigued
