If you are getting sump oil temps over 250, you are way to hot. This may be acceptable after a hard run or other unusual situation, but it should come down afterwards. 210-220 is where I used to see the air cooled engines run.

I am posting this again because I only got one reply and Gerry seems to have been having problems lately:

This weekend's hot weather pushed my oil temperature to 250F to 275F. I didn't run her long last night, but I did notice that the 12 O'Clock position on the gauge is 210F, so although my 250F to 275F is hot... I think Adam's 110C to 115C is not right. What is that in Farienheit? Bus Boys gauge page:

http://www.bus-boys.com/bbvdo.htm

Says: "Acceptable Oil Temp reading should be between 190 to 210 degrees, depending the ambient temperature. 72-83 Buses and Vanagons tend to run a little on the warmer side, so an external oil cooler may be needed to bring the temp in-line."

Adam has suggested my high oil temperature could be a timing problem... can anyone elaborate?

Thanks, Chris
