They are coming from a weld on the water pump housing. Please tell me someone knows a good way to seal such leaks. A re-weld would probably require removing the entire engine :< I also made the first attempted start today. Turns out I have no spark... Guess I won`t be the first to go down that road. I connected the signal from the CAS in parallel with the engine monitor. That connection will be the first to go. Dave Leonard Dave, you might try JB Weld. Brush and otherwise clean aluminum around area of leaks (acetone or similar), mix up some JB Weld (its flows in to cracks and holes fairly good) and apply. I use it to seal air leaks in aluminum tubing with good results. Ed Ed Anderson RV-6A N494BW Rotary Powered Matthews, NC
