If you can somehow create the geometry, 3D printing is a great option

Bruce is a great guy! I flew my F model to Willmar last year and the two of us knocked out the project. You will learn a lot from him. Have fun!

Don't let ATC affect your decision for safety and operating limitations. When ATC gives me the same instruction, I respond with my performance limitations and tell them what they are going to get for approach speed.

Mooney M20F, Lycoming IO360-A1A I thought would put this out there for some advice & feedback. Recently I had my mechanic examine my engine and he mentioned pooling of oil and possible cylinder glazing. Cylinder glazing is a condition that occurs where oil film left on the bore "glazes" to a hard coating and can prevent optimal sealing of ring to bore. The oil here is the result of cylinder head temperatures, CHT'S, not getting hot enough to burn this oil film and. thus prevent the glazing. Optimally, he says, the CHT'S should run about 360-380 F. My engine is seeing a range of 300-320 deg F with an OAT of around 34 F. This is with cowl flaps completely closed all the way, they are closed and flush with the rest of the cowling. All cylinders are running about within 10-15 degrees of each other & measured by JPI930 engine monitor. Of course, my goal is to get these temps into the suggested range. Just wondering if anyone is running into the same issue? what temps do you typically see? Has anyone found a way for the cowl flaps to create more flow restriction? has anyone done anything with engine baffling as to affect the cooling of the engine? Thanks for any feedback. 04/19/2018 -- ADDITIONAL INFORMATION: Thanks for everyone's feedback! what a great resource! I thought I would share what led to the inspection of the cylinders and a give a clarification of the above statements. On a couple of occasions, a ramp guy took notice of a puff of white smoke when taxiing up the ramp. Curiously, I mounted a go pro camera and focused it on the exhaust to try and observe it myself and of course, it never showed up. Recently, I pulled the cowl to check a few items and noticed oil coming out between the exhaust manifold and tube flange at cylinder#4. I immediately sent it in for service and it ended up being a bad valve guide. With all that said, cylinder#4 has undergone a rebuild and will require break-in, hence, the recommended higher CHT's. After clarification and reading all the great comments, this is why he mentioned the glazing and the importance of running higher CHT's. My fault on the interpretation. Fortunately, I do not have any cylinder glazing as all cylinders. were checked at this time. For those that asked, oil consumption has been in the normal range. I have 2 years of history (about 400hrs worth) and it ranges from 0.10 to 0.15 qt/hr. This looks to be well below even what Lycoming says is normal. I found this formula in their manual Normal Oil Consumption (Qt/hr) =(0.006 * BHP * 4) / 7.4. At a BHP of 0.59, this equates to 0.19 qt / hr. Compressions are all good ranging from 77 to 80. One question I do have for all of you, When do you typically add oil? Do you wait til it gets down below the 6qt mark, or, do you add it when it is hovering just above around the 6qt mark? I have been doing to latter. I have heard that these engines typically find their happy spot and then do not vary much. I may be adding too early as it may stabilize at 6qt. Any thoughts here appreciated.

I installed this instead of the boot. Very easy to install and looks good. See picture, sorry didn't have a full view.

Try Aeroleds.com. I put a full set of wingtip strobes, sun tail light, and PAR 46 landing light. VERY Pleased!

Pockets are held in by an automotive push in type fastener. The leather seating and carpet interior was supplied by SCS Interiors, https://www.scs-interiors.com. Really nice folks. I removed & shipped my seating to them for the leather seating job. You order the carpet online. I think they will send you swatches if you want. After you order, they email you drawings of the carpet so you can verify fit into the plane. Mine came in and I do not recall have to make any mods.

Thanks for the all the responses. Nothing seems out of order. Much appreciated!

I own an 1967 M20F / Lycoming IO360-A1A. What do you guys see as your normal operating CHT's? Depending on ambient temps, it varies a bit. I have a flight logged at an OAT of 28.4F and CHT's range from 265F to 280F depending on their location under the cowling. This summer, with an OAT 52F and CHT's 280F to 330F, again depending on location. Cowl flaps in the closed position and in the cruise phase of flight. Data was acquired from JPI930. engine tach is about 300 SMOH Any feedback is appreciated. I am mostly concerned about minimum temps. Lycoming publishes a max of 400 deg F, but, nowhere do they publish a minimum. A few puffs of white smoke have recently observed and the concern is cylinder wall glazing. I have noted no change in oil consumption & having kept a detailed log since I had the engine rebuilt. I am going to have a borescope done very soon to have a look inside. Could be a valve seat. Anyway, any thoughts, personal experience, & data appreciated from you folks!

Could be a stuck open outlet check valve that is allowing fluid back to the pump valve. When you take off the spring return force in the flaps plus the force produced by airflow is pushing the handle back. you might test it by putting in two pumps on the ground and watching it for several minutes to see if the handle moves.

yes, the 430 & 650 will cross talk. they did not at first when i installed. Very nice panel!

There are retrofit kits to go from an F panel to a J type panel When I had my avionics done they took out the old panel and retrofitted with a brand new one like this see attached . My Mooney M20F is a 1967. I have also seen some STC's on other panel kits.

Plan ahead, takes time for Mooneys to slow down. Plan to be at pattern altitude 5 miles out. If you nail your approach speeds, landing is easy. If not, you will float. Unless you have a real long runway to bleed the speed, GO AROUND!

I just put in a carpet kit into my M20F from SCS interiors. Very nice, high quality product!

I have owned an 1967 M20F now for 10 years. I have redone the avionics, new paint, tanks stripped / resealed, and even an engine rebuild back in 2015. Back in 2010, i did a rough cleanup of the interior and had lived with it up to this point. I had been looking for a good shop to do an interior job for me. In my search, i came across Jaeger Aviation in Willmar, MN. (KBDH). This was the same airport i had my tanks stripped / resealed ( WeepNoMore, http://www.weepnomorellc.com). I made a visit to Willmar and Bruce Jaeger showed me his Spatial panel system he designed for old Mooney's. The Spatial system enables easy removal / replacement of the panels without using a ton of screws, which was one of my biggest gripes when i reworked the interior. My visit was back in 2016. This year, i decided to really redo my interior. I had SCS Interiors (https://www.scs-interiors.com) recover the seats in leather and also bought their carpet kit pre-fitted for M20F. So, i made the trip Aug 1, 2017 and i worked alongside Bruce Jaeger, which, saved me several labor hours. He taught me how to repair, patch, and refinish the old panels that we would be re-using. What a nice outcome! Along with the new Spatial panels, the old window frames, baggage area plastic, nose gear housing, and headliner look practically new! We removed about 350 screws from the old interior and only re-installed about 40. The side panels and spar panel are easily removed for maintenance & inspection. i have attached some photos of the a job well done. Feel free to ask me any questions. If you would like to contact Bruce about redoing you interior, http://www.jaegeraviation.com, bruce@jaegeraviation.com, (320) 444-3042

Thanks for all the responses. i ended up doing a precision measurement on the fitting that came out and it ended up being a 12-36 thread. http://www.kingfisherlubrication.co.uk/catalogue/greasenipples/564_HydraulicGreaseNipple1236Uns.html. Good ole Amazon sells a tap as well. Wierd!

Does anyone know what this is? No luck with this part number with any commercial mfgs. though it might be Alemite, but, no dice. See attached pdf with circled items in graphic and text. My aircraft is an M20F, late 1967. grease ftg ref.pdf

1967 M20F, MANUAL TRIM. this is in regards to the trim wheel, what sort of backlash is normal? In other words, if you wiggle the wheel forwards / backwards what sort of slop do you see before movement of the trim actually occurs. i am seeing about 5-10 degrees. i am curious what others are seeing.

I installed this kit into my M20F, it works great! Really pay attention to the grounding / bonding connections as these are critical to the system working correctly.

Thumbs up to WEEP NO MORE. I had my tanks sealed back in 2010. in 2015 annual i found a slight leak in each wing and took it back to have Paul look at it. i flew in on a Sunday night and went back the next morning. He usually starts at 4:30 am and had found the leaks which were just pinholes, already repaired them, and just waiting for sealant to cure. i was back in the air Tuesday morning headed home. No charge for the repair (7 YEAR WARRANTY) and he even let me use his car while i was there. A really great guy! MONEY WELL SPENT!

Thanks guys...as a matter of fact i contacted LASAR earlier today and they are having a number of sets being made and will have available to sell within the next 2 weeks.

Anyone have a set for sale or know where i can purchase?
