Do vernatherms ever stick? My oil temperature on climbout will increase until about 220, then almost immediately drop back down to around 190. In steady cruise the temp will be around 185-190, then, for what appears to be no reason, the temp will climb to 220 over the course of a minute or two. It'll stay there for 30-60 minutes and then randomly drop back down to 185 over the course of a minute or so. Currently running 55-60psi in cruise. Was thinking about increasing that a bit to see if the extra pressure would help open the oil cooler circuit as the temps come up, but besides that I think I have to tear off the accessory case and do some inspections of the vernatherm. Anyone have any experience like this?
