Greetings hot weather Vanagonauts,

My 82 has a fairly new engine (3000 miles) is running 15 - 50 synthetic. On steep climbs or long freeway driving in the heat, my oil temp can go above 220. I don't like to do that so I moderate my speed between 55 - 60 mph. Even then it can c,limb to undesirable levels. When the temp goes high like my oil pressure drops to under 20 psi even at higher RPMs which freaks me out. I've experienced this twice now. Then when I push the clutch in, pressure drops to almost zero which I don't like at all. So I'm thinking of switching back to castrol 20 50 which i used or years without this much loss of pressure at temperature. Cold engine oil pressure is above 45 psi. When its warm it pressure is steady around 32 PSI until it gets hot, then it drops. Thoughts from the oil gurus?. Is it my oil pump? The oil I use? Or just hot weather driving? I don't think it did this with Castrol 20 50. Should I worry more?

Makes me want to get Cylinder head Temp (CHT) gauges to really start freaking out. Ken Wyatt 82 westy SLC, UT
