  1. Amazing how much difference there is in 2 years of production.
  2. If you look at the photo, the battery box vent tube comes off the side and goes down about 8” to the pilot footwell part of the firewall. You can see it just above the white battery cable. No way it attaches to the tube off the doghouse in that configuration. Something must have been modified over the years. Battery box drain tube routes to left cowl flap opening.
  3. That makes sense. There is a tube in the side of the box that I’ve assumed was just a vent. Since I am using a sealed battery, should I still connect it, or should I seal off the tube to force that air across the #4 cylinder. I’ve closed off the gaps at the rear of the doghouse, lower cylinder barrel area, on both sides, and tightened up the front baffling as well. Still finishing up the annual so haven’t determined any benefit yet.
  4. Yes, there is a small SCAT tube that comes from a small opening in the front of the lower cowl up to the area between the accessory case and the firewall.
  5. Any idea what this tube is for? It can’t be to cool the battery box. I have the tubes that supply cooling air to the mags but can’t figure this one out.
  6. I used Gee Bee’s baffle seal. It’s better than the red rubber. Well reinforced.
  7. My logs are at the airport for annual. Let me look it up next time out there.
  8. So maybe this should be another post, but I’m curious how many Mooney’s with O & N bladders have fuel gauge problems. I’ve had issues since my bladders were installed. I had my senders rebuilt by Lockhaven Air Parts last year. Worked perfectly outside of the tanks. Don’t work so well inside the tanks. Unfortunately my tanks are full and I’m down for annual now.
  9. Is this opening normal or should it be sealed? It is behind the barrel on #4 cylinder. Had to pull the battery box to get this photo. The same opening is behind #3.
  10. I found the bottom seal to be a bit short of the groove so it seems to be pushed down out of the groove and could be allowing air to escape to the lower engine compartment as Takair has stated above. I’m going have it repositioned it to tighten it up. Will post results when the annual is complete.
  11. Out of slot as I was starting to remove the top of cowl. Stopped to take photos. Thanks for all the ideas. There are some large gaps at the starter. Any closure ideas? Would this have much effect on air to #4?
  12. Plan on contacting them tomorrow. Wanted to do some research before that as I know they’ve got to be swamped with similar requests.
  13. My engine was rebuilt by Penn Yann in 2020. They provide a detailed itemized parts list. Mine includes the affected rod bushings. I’m outside the affected dates but how do you know how long the bushings were in their inventory before being installed. Like ArtVandelay stated above, without serial numbers how do you know?
  14. I started taking my airplane apart for annual today and took some photos of the doghouse. I used the lighting technique to look for openings and found some mostly at the front bottom in front of #2 & 4 cylinders. Will discuss with my A&P a plan to close up. Also may use some RTV at the top rear were I can’t tape as well and a bit of light is showing through. Not sure if this will fix my issue but can’t hurt any.
  15. Worked in heavy industry (Engineering) for 50 years. When you make a statement that suggests something is idiot resistant, along comes a bigger idiot.
