Brickren,
About 5 years ago I found two fixes.
I pulled the thermostat and put it in a pan of water and turned on the heat.
watched for a change...couldn't see a change. Borrowed a thermostat from a friends 1970 Porsche 911, 2.2 liter and checked it in the pan. It turned out that MY thermostat was STUCK!
My friend recommended
www.pelicanparts.com lots of spares on their classified link) . I was able to get a used one that works fine.
This helped bring the heat up, but I still had some foaming but not nearly as much.
My next idea was to insulate the oil pan. I bought some silver bubble insulation about 1/4" thick and made a template to fit around the oil pad and as far up the crankcase as was easy. I folded the flaps up the sides and held it in place with giant zip ties.
This even helped more.
Good Luck
