Orma First, thanks for your patience. I am using straight 40 wt. Had 5-30 at first but changed to 40 I did verify that crank, rod and cam bearings were plasti-gaged before final assembly. Have to trust my son on this one, he assembled the lower end and swears that it was done. I will change the pressure relief spring. I will be amazed and delighted if it is that simple. I will try that before assembling the remote oil cooler. Today I am going to attach a little homemade air scoop over the cooler to see if that helps the temperature. Have ten hours taxi tests already reaching speeds of 40 mph and am chafing at the bit. Am afraid to take off with the assumption that speed and level flight will cool the oil down enough to change pressure. As the old MG auto company used to advertise; Safety first and safety Fast!
