sooooo. why dont you pull out the dipstick and measure the temperature
of the engine oil all the way down the hole?

That sounds like a pretty damn good idea. You can buy relatively cheap DVM's
that come with temperature probes included.
http://cableorganizer.com/triplett/d....htm#featuresI just measured my probe. It is a 37" wire lead with the tiny probe at one endand the plug at the other. That should be plenty long enough to reach down tothe oil level in an aircraft engine.You could also tape the probe to your oil cooler inlet tube to get an idea ofyour oil temperature with the engine cowled. (I do something like that tomeasure the hot fluid temperature from my car's AC compressor so I can add theproper amount of refrigerant.)Vaughn
