How Did These Maintenance Issues Go Uncorrected? | Mooney M20C Vlog #5

[@EatPezzzz]

4:55 that's not the oil pressure pickup, that's the fuel primer inlet. There is no pressurized oil in the heads. 10:35 there is not vacuum in the exhuast. That's the cold air source for your heater. The heated air going into your cabin has to originate from somewhere before it's heated.

[@MyTimeToFly]

Thanks man. Kind of curios about the fuel primer inlet...I don’t have a primer. What else could it be?

First thing i noticed with the cowl off is that the hose attachment point on the back of your engine doghouse/baffles has no hose attached. scrolling through some of the comments, i think you got this fixed, but i dont see any good list of everything that hose does. the hose you are manipulating at 9:30 in the video is meant to be attached there. The function of that hose is to feed ram air from the doghouse to the muffler shroud, both for providing cabin heat and for carburetor heat. That hose being disconnected is incredibly dangerous, for several reasons: 1: CO ingress - with that hose loose in the cowl, it is intaking cowl air instead of fresh air, and can allow exhaust into the cabin ventilation system. 2: Carburetor heat - without that hose being fed ram-air, applying carburetor heat, which intakes through that hose, will result in SIGNIFICANT power loss. 3: carburetor heat - the inlet path through for carb heat is UNFILTERED (this is why you should never use carb heat on the ground except during runup test) - that hose loose is sucking in all the dirt in the cowl... straight to your carb. 4: engine cooling: with that hose nib open, the air which should be going through your cylinder fins and keeping the engine cool is bypassing them entirely to go through that hole and pressurize the inside of the cowl, further increasing resistance to airflow through the cooling fins.... so, yeah, that one hose can kill you four different ways if it is not attached.

[@MyTimeToFly]

Thank you for the great details! I did reattach the hose, and it's stayed in place since. As a matter of fact I look at it during every preflight inspection.

[@davidscramlin6112]

Great video! Owning a plane looks to be a lot more than just flying it!

[@MyTimeToFly]

Thanks again Dave. It's proving to be challenging, yet rewarding.

[@kimkuck4473]

Replace the GE landing light bulb with LED. I did on my 1965 M20C. The LED draws 1amp! You can basically leave it on continuously because it will last longer than the plane will. You will not be sorry. Do the Nav light too, since they have to be on continuously to power the Tailbeacon. Lastly, get on Mooneyspace.com if you haven’t already done so. Phenomenal resource for Mooney owners.

[@MyTimeToFly]

Thanks so much. LEDs are definitely on the list to do soon. I’ve found Mooneyspace to be a great resource as well!

[@mikekoetje4498]

Where are you based? My buddy and I recently purchased a 201J as our first airplane, based at Z98. What a blast so far.

[@MyTimeToFly]

Very cool, I’m just up at Sparta (8D4). There are enough of us around, I’m thinking a Michigan Mooney Meet Up is going to have to happen!

[@mikekoetje4498]

My Time To Fly Absolutely! When this Covid garbage clears we often times go find breakfast somewhere on Saturday mornings. Let’s do it sometime. Always looking for a new excuse to fly.

[@MyTimeToFly]

Sounds like a plan!

[@phoughton5665]

My 66 Mooney used a 100 watt bulb instead of a 250 watt. Check parts list for your Mooney.

[@MyTimeToFly]

I replaced what was already installed...but will go back and check parts for sure!

[@carlpease4230]

Great video Cory, Reminds me of when we owned the 172!!!

[@MyTimeToFly]

Thank so much Dad!

[@pilot-plane-coffee1678]

My experience as well- over 6 and it ends up all over the bottom. Solid video

[@MyTimeToFly]

Much appreciated!

[@pilot-plane-coffee1678]

What product do you use to clean off all the oil- seems like if it sits, turns into super glu.

[@MyTimeToFly]

Back in the day I used simple green, but now my wife has this stuff “melamagic”. It’s some organic stuff she buys through a secret shopping network...or something like that. Anyway, seemed to work okay. Do you have a go to?

[@Superdummy803]

Just curious. I am also looking at a Mooney for my first plane. I think they are great at what they do. Are you at all concerned about the factory shutting down and the availability of getting parts?

[@MyTimeToFly]

No concern here, we’ve got really good support through LASAR. Bottom line, there is a demand for parts. Where there is demand, there will be supply (my opinion).

[@pallen2980]

Looking to purchase a M20F, G, or J. The more you can share about owning a vintage Mooney the better. Thanks.

[@MyTimeToFly]

No problem, I’ll make a video talking through the first year of ownership

[@sey1yes2]

Going to replace the landing light with a great LED? As well as wing tip lights and strobes?

[@MyTimeToFly]

I’m sure I will eventually. Last I looked the LED strobes were quite pricey. I will have to review my options!

[@jrbmsu]

Great video Cory.

[@MyTimeToFly]

Thanks Jeff. Puts clean, inspect & lube in a new perspective!

[@waqarsyed6641]

Love the Mooney thanks for sharing dude

[@MyTimeToFly]

My absolute pleasure!

[@N182NS]

The small line coming off number 3 cylinder is manifold pressure gauge the dipstick tube get tight on the dipstick and when you check the oil it has a tendency to unscrew it they also crack and brake off some times take it and make sure it is not cracked

[@MyTimeToFly]

Will do, thanks Nick

[@jimbiller9682]

Indeed, that's more of a Lycoming issue than a Mooney thing. Happens at my club frequently, and we get a nasty grahm from the club pres

[@rchn1315]

The hose is to supply fresh upper cowling air down into the heater shroud around the muffler to heat the air for cabin heat. As part of the inspection, it can be checked for exhaust leaks. However, a leak can happen any time so a CO detector is a good device to have. Do NOT depend on a finger pulse oximeter since carbon monoxide poisoning looks like FALSELY oxygenated blood to the oximeter!! Once CO is bound to hemoglobin, it is practically permanently, chemically bonded! So it is imperative to PREVENT CO exposure. BTW, I'm PhD Chemical Physicist and world expert in medical grade commercial oximeter design with over 25 patents in the field. I tend to use the minimum heater airflow and use the side ball vent to direct air directly at me. This article is reminding me to get a new CO detector!

[@MyTimeToFly]

Thank you for the great information! I recently bought and began using a digital CO monitor, it has given me great peace of mind. 2ppm during my most recent trip.

[@darrylday30]

Thanks for the info. I didn’t know about about the oximeter false indication. Getting a new CO detector as well.

[@Alfaspiderman84]

The line your looking at @4;40 is the manifold pressure gauge.

[@MyTimeToFly]

Roger that, thanks Dan

[@Alfaspiderman84]

@@MyTimeToFly I have that same motor in my Cardinal.

[@Alfaspiderman84]

KRMY

[@MyTimeToFly]

And a sweet motor it is!

[@Alfaspiderman84]

@@MyTimeToFly One thing to look out for on that motor is that the cam is on the top of the case, and being there it can get rust on it if it sits too long without flying. So fly often. At least once a month or so. Also adding Cam Guard to the oil helps alot too. Happy flying!

[@phoughton5665]

Wrong one was installed on mine also. Kept popping the breaker at random times.

[@MyTimeToFly]

That can be incredibly frustrating, especially random electrical issues!

[@jofido]

Thanks Cory. Nicely done.

[@MyTimeToFly]

Thanks a bunch!

[@jimpace4575]

My wife and I are travel nurses, I’m a pilot and my wife is a student pilot. We’re thinking of buying a Mooney M20 to use as a weekly flyer to and from jobs. How reliable are Mooneys? If we put the money and work in would you trust the plane to get you to work?

[@MyTimeToFly]

Sounds like some great adventure through your careers! It seems like a Mooney would fit your mission quite well. I might think about spending enough to get one with TKS, or at least a turbo model to be able to get up above some weather. Are you and instrument pilot? If not, that’s a clear must have before traveling for work in a GA airplane!!!

[@kimkuck4473]

Also, any oil above 7 qts on mine will be quickly blown out the crankcase breather and will wind up on the belly. I keep mine between 6 and 7 quarts.

[@MyTimeToFly]

Thank you, this does make me feel better. 6 to 7 quarts is now my target.

[@paulgraham5370]

What happened with your pre-buy inspection dude?

[@MyTimeToFly]

Great question! I do believe the issues I identified happened during work that was performed after the pre-buy. But...it was all at the same place!

[@oddsends6048]

Hmm, dirt and oil in/on the a/c is an indicator for the mechanic. Leave it on for annual so your mechanic can see it as evidence. Give your mechanic a hand with it and learn from him/her

[@MyTimeToFly]

I hadn’t thought of it that way. Luckily I flew it enough prior to the annual to replace all the oil I wiped up. You certainly make a good point!

[@libertine5606]

Dump the landing light! They are rated for 25 hours but you may not get even that since the filament can just break from the vibration. LED or HID is the only way to go.

[@MyTimeToFly]

For sure, we should have done the LED light...but sold before we did.

[@johnbozman1]

Nice Work man. Keep it up...

[@MyTimeToFly]

Thanks so much!

[@N182NS]

The hose goes where you put it the hose routs ram air into the muffler for carb heat and cabin heat

[@MyTimeToFly]

Thanks Nick. I’ll have to see what kind of effect it has. Time to get back up in the sky!

[@calandroaudio]

That hose is your carb heat. Kind of scary when you’re in the N in freezing temps!

[@lnomgaudas1307]

Youre a cool dude flying a plane. But just a thought, if you can fly and 'repair' your plane with the VERY limited understanding of the mechanics (quite funny I give you that), then a lot more people should really be into GA! Keep your work up! Best,

[@MyTimeToFly]

Thanks man, perhaps my knowledge is a little more than "limited". Although I'm far from an expert.

[@danielruff4632]

Throw the old school light away! Get a Whalen LED landing light. You won’t regret it. They’re easy to put in and last a very long time. They’re much brighter too.

[@MyTimeToFly]

I will look into it closely. More than 10x the cost, but sounds like it’s worth it!

[@dalestephan6777]

Find an FAA cert inspector to tell ya what needs fixin.. have him shoe you whereverything is Etc then have an A&P correct his gigs then you will k ow what's been done.. list for inspector the A& P . And you!

[@MyTimeToFly]

Thanks for watching Dale. The airplane has now been through annual inspection twice, and we feel like we've got most everything in good order. It definitely pays to inspect the plane in the presence of a good A&P / IA.

[@jimbiller9682]

Cory; I am pretty sure you can get an IPC [illustrated parts catalog] for both the engine and the airframe. For some reason I thought that would come with the airplane when you bought it, as well as the Mx logs. Probably no law says you should, just thought it did. you could probably find a Mx manual on line somewhere...Found this site for $40 mooneyspace.com/files/ [looks like you saved that much by not replacing your pants]. All that stuff you did should probably be written in the aircraft Mx log somewhere.

[@MyTimeToFly]

Thanks for the link, I’ll check it out! Gotta have some good work pants around! Thanks for the laugh!

[@BillCoSmith]

Can use loctite or something similar?

[@MyTimeToFly]

I know I could, but I’m not sure if I should.

[@BillCoSmith]

My Time To Fly maybe Teflon tape? Blue locktite is made for temporary use, what does the AP mechanic say?

[@BillCoSmith]

My Time To Fly seems like you need something to keep the screws from backing out

[@MyTimeToFly]

I will have to consult

[@darrylday30]

Check your Lycoming manual, service bulletins and service letters first. There’s a long well documented history with these engines. The factory stuff is tedious to read but it’s safe and usually the most effective way to go. If you really want to take it up a notch, I highly recommend the series of books and articles by Mike Busch of Savvy Aviation. BTW, nice airplane you’ve got there. I’m looking for one just like it. I’m really enjoying your videos.

[@allenjones3384]

Nothing new for those who have owned a Mooney for several years.

[@MyTimeToFly]

I guess I'm building my list of what to watch out for. Do you have any "gotcha" items I should focus on?
