Hi Doug, 2200 serial 3574 with 7/16" through bolts. 168 hours in a Sonex. CHTs always below 130C, EGTs always below 720C on hottest (#1) I was recently going over my engine after a 4.7 hr trip and noticed a bit of black oil sitting along the top of #4 cylinder flange, forming a fillet between the crankcase and flange. What is concerning me is that when I wiped it off, a piece of the silver cylinder coating flaked off with it. The torque seal on the nuts appears intact but I haven't checked the torque on the cylinder base nuts yets, thought I'd get your thoughts first. Cheers PS where is a good source for new tubes torque seal? |
