I think I cracked a tip or body on the way home this evening. No cel and not down on power but I am carring lower oil pressure than normal ( manual oil pressure gauge). no leaks but I checked the oil and it seems a little higher than normal but this was checked hot. egt's the same at cruising and the rp is still 17.5 to 18k at cruising. I have noticed a little more white smoke and sputter on starting in the am but I figured this was due to it being cold and lower compression. what is the charge to test my flux 3.5 and repair them and possible upgrade to 4.5??? thanks Robert
