I have a 421 serval with 35mm air strikers and r2 pipes. I'm running 158 main and 48 pilot and about 500-800ft with 22cc domes running 110 fuel (turbo blue). I thought it was the oil, I was running ams oil dominator now running klotz at 32:1. I'm blowing oil out of every seem, hole, silencer... Everywhere you can think of in the exhaust. When I say a lot I mean a lot. At one point it was a steady drip conning out the rivet in the silencer. I cant seem to figure it out. I know I can seal up all the seems it then it just poors out the silencer even more. Any ideas would be great.
