  1. My good friend and a Mooney M20J old timer has an issue with his IO360 . His engine was running rough due to low (zero) compression on one cylinder after take off from KSBP. It appears that one of the intake valves is cupped and not seating properly. Please see the pic. A sticky intake valve is the primary suspect. Has anyone seen this and has any idea what could cause it? The mechanic pulled the cylinder today and will send it out for repair. The main question is what could cause this other than a sticky valve?
  2. Does anyone have handy a shopping list for the annual on an IO-360? For example, eight copper plug gaskets, the crush washer for the oil screen, oil filter, etc.? Possible 'contingency' parts--like those assemblies (springs/drilled bolts/castle nuts) on the exhaust. I am doing 'Owner Assisted' this year with an A&P/IA buddy who has the jacks and inspection tools, but I need to lay in the consumables. TIA, Harley
  3. 1967 M20F with Rayjay what is the spark plug choice of 2018 for massives and finewire.
  4. I suspect my engine is sagging and this causing the cooling issues I'm having. So, is it shims or is it mounts? How do you evaluate the state of the mounts? Since I just replaced the donuts (and my gawd how my landings/ground handling have improved), it may be 'time' for the mounts.
  5. We're pleased to let you know that N5976Q is now supported for Report Cards and Trend Analysis reports. We have added support for the M20 (A/B/C/D/E/G) / IO-360 cohort. If you are a SavvyAnalysis Pro, SavvyMx or SavvyQA client, you can create reports online, on demand, for your aircraft. If you use the SavvyAnalysis Free service you can learn more about SavvyAnalysis Pro. Not familiar with our reports? See the Reports FAQ, sample Report Card and sample 5-page Trend Analysis report. Questions or comments? Please contact us.
  6. We're picking up 1ZX from an annual turned engine overhaul on Tuesday. We previously had the Firewall Forward HP plus STC, but opted to not use the 10:1 compression pistons in this overhaul. So, the engine is a standard IO360-A3B6D that would be in most M20J's. Triad did the engine overhaul, and AGL Aviation did the removal and reinstall. I will be asking Triad and AGL the same question, but I'm curious to hear Mooneyspace's opinions as well. What's the best break-in procedure and schedule for oil changes during the break-in period? Triad ran the engine for a couple hours on their stand, and AGL has ground tested the engine some. Lynn at AGL is giving us a 2 1/2 hour break in flight procedure that we will complete before our final departure home. From what little I know about new airplane engines, I know they typically use mineral oil in the first hours. For how long do you use the mineral oil? And what's the purpose of mineral oil vs regular oil? Any other general advice for helping get this engine last well into TBO hours? The Firewall forward overhaul was at about 1650 hours when pulled. In it's defense (if there is one), the plane sat for about a year and a half before we bought it with only an occasional ground run.
  7. Best brand/part # for fine wire plugs for a 1967 M20F with IO360 A1A with a RayJay..
  8. Take off and landing with our Mooney M20E at the 6Y9, Pricket-Grooms Field. Located in Sidnaw, Michigan's Upper Penninsula. For reference: The runway is 2,600 feet long, elevation 1,372 feet. Density altitude on this day was around 3,000 ft. Single pilot + approx. 30 gal. of fuel. Take off: Rotate at around 65 - 70 mph, gear up as soon as plane is stable. Flaps up at 90 mph. Continue to accelerate in ground effect, then climb out. Landing: Speed 'over the fence' around 75 mph, full flaps. Flare until she is done flying.
