Drove it today on a highway trip. The needle climbed a little 2 or 3 times, but it never really overheated. Around 90 degrees ambient at the time, probably 8 degrees cooler than the last time it overheated. I ran the A/C full blast.
I tried the block test again anyway...it was negative. So, I'm still scratchin my head. Guess I'll drag the trailer back here from the farm next weekend, see what happens.
I did look into doing a head gasket job myself, looks like fun :-(
