Mine are not evenly spaced. They are much like the first photo with a large jump between 6 and 8 quarts. However, I did get an answer from them. I have a narrow deck O-360-A1D. The part numbers you listed were for a wide deck. My dipstick is correct for the narrow deck O-360-A1D. I have pasted their response here. Hi Greg, The dipstick part numbers you mentioned below comes from the wide deck O-360 parts catalog (pc-306-1). The serial number you have indicates you have a narrow deck engine where you want to use parts catalog PC-106. PC-106 also has four different options for the gage assembly. LW-16783-18 superseded LW-14758 which is called out in the narrow deck IPC for the O-320-D1A. LW-16783-18 is for an 8QT system that is 19.44” long. Additionally, there is also service bulletin 612 regarding LW-16783-18 for the IO-360-M series engines. This Bulletin talks about replacing the LW-16783-18 with LW-14760 for the IO-360-M.

Well, with all this talk I decided to go look at the dipstick in my O-360-A1D engine. The part number stamped on mine is LW16783-18. This is nowhere close to the 3 listed in the parts manual. A quick google search said this one is for the IO-360-M engine. So I put an email into Lycoming to see what is what.

I believe that the LTSIO is a Continental Turbocharged fuel injected engine that is left turning when viewed from the back (The L in the front). They are usually used in some twin engine airplanes to eliminate the critical engine. It is a O360 but not sure what the 0KB means. This is a shot in the dark for you but I am pretty sure the L part is correct. I seem to remember that years ago from my twin training.

I am late coming to this discussion but not all C models are created equal. My 63 C model has a gear speed of 120mph but the flap speed is 100 mph.

Thank you for posting this. That goes such a long way to explain how this system works.

Just got a call from LASAR. They are shipping out my intake duct today. So I guess everyone who ordered one can expect them soon.

Here’s two examples both with the gear horns blaring away and completely ignored.

I found in the paperwork the part number AEL-11750-S. That is different than the Lycoming part number LW-11750. For all you smarter than me folks…would my part with that part number still fall under the AD?

So, a curious question….I had to have my engine taken apart in 2013 after problems with an earlier overhaul. This work was done by a major engine shop. They mention nothing in the log entry of part numbers for connecting rod bushings or assembly. The only thing mentioned is that the engine was reassembled with new rod and main bearings, new rod bolts and nuts. No part numbers listed other than for the crankshaft, camshaft, pistons, piston pins and piston rings and other parts not related to this. To find out if I have the affected parts would I have to contact the engine shop? I’m thinking yes.

Actually, I think I am in the running for that….

For those with Lycoming engines that are interested in what Lycoming considers maximum oil consumption, here is a formula they put in their break in service instruction back in 2010. “The following formula is used to calculate the maximum allowable oil consumption limits for all Lycoming aircraft engines.” 0.006 x BHP x 4 ÷ 7.4 = Qt./Hr.

@hammdo Quick question....what oil dye did you use for your test run? Thanks.

This was posted this morning on the Garmin YouTube channel. It may be it. The new G3000 Prime.

Just as an FYI, I went through the ordering process for it just to see what it would cost. With the top of the line, everything you can get including the Latest Apple Pencil and Apple Care, the total cost was $1206.00. This included the case they offer as well. Cellular and WiFi. Just in case any of you were thinking of getting one. My ipad pro is just fine for me, thanks....

Maybe add another option...."I have the greatest gear system ever made...A Johnson Bar... so I don't need no stinkin' spring."

So, in light of this poll and some of the responses, I decided to revisit what the "book" speeds are for my Mooney. I looked them up in the AFM that is specific to my airplane. So, at 5000 feet with RPM's at 2500 and MP at 24 inches, the "Book" True airspeed is supposed to be 180 mph or 156 knots. Seems to me that is a little high for a C model. So I went out and did the TAS check using the cardinal headings and GPS. At 5000 feet with the RPM and MP set the same, I got 143 knots TAS. 10 knots slower than "Book". So either I have a dirt slow C model, or I have lost a lot of speed in 61 years the plane has been flying or they had absolutely perfect conditions, with a perfect airplane, and a perfect pilot when they got their "book" numbers or a combination of all of the above. And I was roughly the same weight as shown on the chart in the AFM. I would really like to see any C model that cruises at 156 Knots true. That is getting into J model territory I think. No question here, just commenting on my airplane.

Thanks @Rwsavory. I found what I was looking for.

1963 C model… I know this has been covered many times on Mooneyspace but the search engine is not so good at narrowing down things. I have three screws in a lower panel on my right side fuel tank that are weeping some fuel. I would like to just try to fix these three screws. What is the best sealant to use? I am thinking I can remove the screws, put some sealant on them and put them back in place, correct? Thanks for any advice.

For you folks that use Buddha Belly, the instructions on the website say to try first in an inconspicuous spot and to dilute as necessary to avoid staining. Have any of you found that it has stained anything? Thanks.

Have you tried Release 32 oz Ready to Use Aircraft Cleaner/Degreaser | Aircraft Spruce or Xhaust & Soot Remover | Aircraft Spruce I have found that these two work very well on tough issues but you have probably tried them already. Just a thought.

This may have nothing to do with nothing but back in 2022 Garmin issued a service bulletin for the G5 saying that if the G5 was not powered up for an extended period of time, the battery would drain to 0%. They also published a list of serial numbers affected by this Service Bulletin and their website shows this list recently being updated as of yesterday so I wonder if you somehow have a unit that falls under this old SB. Just a thought. (2022) Service Bulletin 22013 Rev A: G5 Backup Battery Discharge | Garmin Customer Support

I had an issue much like this with my C model when I first bought it. My issue was a worn out accelerator pump in the carburetor. It is a leather type membrane that may wear out or break. When it does, you cannot prime the engine and may take many, many blade turns to start if it ever did. I wore the battery down one day trying to start it. When the accelerator pump was repaired, the plane started on the first turn of the prop. So, I think I would look electrical first like was said above but do not rule this out.

The oddball file name looks like it may be that map of the US of all the states he has been too. The file name looks like a list of state abbreviations if you break them down into their 2 letters. The pic just isn’t coming through.

So this thread has made me read over my entire policy which I have never done. Is it bad that I am two pages into it and am already confused?

It is amazing that after 17 years of ownership, there are still things to learn about my airplane. My 1963 C model has the 3 pin external power receptacle. I just thought that it was standard and not some option. I found no where in all the logs any entry for its installation. Interesting.
