I was thinking the same thing. This topic seems to have rambled on. Later this spring, after I've gotten some temperature readings, I'll post the results and then I think I'll be done with this topic.

Good point. We don't know for sure. I rode to work today in the lovely Ohio liquid sunshine which got me thinking. Since it was leaking on the front of the engine maybe it warped from the water being splashed up on the front of the engine in the rain and this whole oil cooler idea is a waste of time.

You recall correctly. I too am not fully convinced that WOT for extended times at about 7K RPM would have caused an overheat and cyl, head warp. I would only down shift to 4th WOT for not more than a few minutes. Just enuff to climb a hill or overcome whatever was slowing me down. I usually shifted back to 5th around 7.5k RPM occasionally going up to but not exceeding 8K RPM. Essentially I don't think I was ever in 4th WOT long enuff to cause a problem.
