Over heated Ford (Mercury) Engine on my F8

[gjamo]

Back when I was a kid on the farm at Corowa everything that ran ended up being powered by a blitz or carrier motor including ski boats and tractors. The trick we found as long as all other cooling system components were in good condition was to run an extra pint of oil in the sump.
85% of engine heat goes to oil to be disipated. We never suffered with oil foaming or pumping it out and motors ran hot but acceptably ever during harvest in a header.
