As loyal readers may recall I have been concerned about oil seeping/leaking out from around my oil filter seal on my remotlely mounted oil filter. I have replaced the remote mount and tried 4 different
K&N filters and an STP filter to no avail.
Well, in the tradition of test it til it breaks, after focusing on some other tasks today, I cranked up the engine one last time to see if my "task" had screwed anyting up. Since is was a coooool 85 degress and my
oil temps were showing about low after start up, I figured I would go WOT and see how long it would take to get to 210....uh, pretty quick for those curious (even though I can idle at 1400 - 1700 dang near all day). I looked to the engine and could see the
small drip marks of the oil leak, continued at full throttle for a few more seconds and shut down. I got out of the plane and saw a huge puddle of oil where the small amount had been. Upon closer examination, oil was all over the bottom of the engine and
I had a nicely oiled prop (pusher Velocity). Almost immediatly I noticed one of my heavy duty Aeroquip oil lines had burst. Hmmmmm, the Oil Pressure reading never went over 75 and was around 35 when idle (as a matter of fact, at idle, it is usualy around
30). I belive these reading to be in the normal ranges.
Anyway, I have plans tonight so I had to push the bird back into the hangar and think about things. As suspected, the seeping remote mount was a mere symptom. Now to determine what was causing the apparantly high
pressure near the remote mount and the burst hose. The lines are fed to the mount correctly, but I shall check again. Y'all's thougts are appreciated and sought.
On a better note, after fighting some electrical issues, esp with my coils, I kept getting inconsistant reading on the multimeter when using the Mazda coil harness. I finely gave in and cut it to pieces and wired
it direclty using just the connectors into the coil and eleminating the plut into the old harnes by directly soldering the wires. This seems to have solved the problem. It is great to turn off secondary, primary/coils, injectors in various patterns and the
engine still run as expected. Now, I am convinced that the rotary can run, if poorly, on ONE coil as it may do if someone forgot to reattach the leading coil spark plug wire on rotar one......don't ask how I know <g>.
Well I am off to a fine dining experience...or so I hope. Great to comtemplate tomorrows activity.
Thanks for your attention.
All the best,
