Back In The Shop! First Oil Change, and MoGas Modification

[@pcorf]

That Cessna 172B look gorgeous! Simple but beautiful scheme.

[@darrellbedford4857]

Great looking aircraft. As far as the oil samples, they will show the health of the engine and if any problems occur. We used them at my last job and it was helpful to track the condition of the engine. it will also show if you have bad bearings, fuel leakage into the crankcase as well as water in the oil. Keep the reports, they will be helpful for the next annual. Chris is aware of these reports and the usefulness of the reports. As mentioned before Chris is not only an excellent AME he is an excellent teacher who does not mind sharing his knowledge.

[@K7PLC]

I'm loving all the C-FMVU videos, but especially shop videos with Chris. He needs his own channel!

[@madisonromero3529]

You are lucky to have found one of the most knowledgeable mechanics there is..... This guy looks like he needs to be protected. A treasure in aviation.

[@jcboom6894]

I am so glad at this time in your life you found you did not have to spend thousands on camera equipment and got to spend it on an airplane for you to enjoy restoring and you and Julie to enjoy flying to camping sites. Please be mindful of the weather. I personally know 6 dead pilots of small planes who thought they could beat the weather.

"That's why I'm not a mechanic." In my book: you're getting closer to it, Glen. And, again: it must be so satisfying to know this aircraft so well. So much into every detail. Like cooking. Like crafting. We live to learn. Amazing episode!

[@davidhofman4341]

I owned a 1961 172 in late 1980's. As a A&P ad IA I did my own inspections. The plane had been stripped and painted 5 years earlier. During the annual with the flaps fully extended the flap balance cable rusted the length of one inch with only three wire strands the flap down. Stripper had gotten on the cable.

[@GlensHangar]

Something I was warned about when I stripped it - definitely did a lot of extra rinsing and neutralising, and all of those corrodible bits are high on the watch list for the next few years.

[@murlthomas2243]

That plane is sweet! The livery really pops, and I know for a fact the engine is great. Good job!

[@GlensHangar]

Thanks a lot! I have good feelings about the engine too.

[@richardriisberg2694]

Great videos. I did my plane a few years ago it all comes back to remember. Your engine was built by Grandfather and his two brothers at Continental Motors in Muskegon, MI. Grand father as head of assembly. Enjoy your videos have watched all of them. Enjoy your plane.

It never ends. An airplane is like a second family - lots of money and time. We had a 63 P172D and spent far more time and money on looking after it compared to hours flown. We got ripped-off on the Peterson STC as well as other STCs like the one for removing the fuel pump on an Avcon Conversion.

I'm just trying to envision Glen pulling into a gas station in his plane to refuel. That would be a hoot! I'm sure those airports he's talking about has pumps that are handily accessible to planes though, but this image in my mind gives me a chuckle

[@skycarl]

Great idea putting in the filter adapter. Personally I would not go with the auto fuel adapt,,, as they say to each their own. May be the sign of the times.

[@GlensHangar]

It's a 'nice to have' / just in case type thing... I'd rather have it for those airports where 100LL Avgas is in short supply or non-existant, but Ethanol free unleaded is abundant.

[@ansonmoxness5403]

@@GlensHangar Don't worry about the autogas detractors. I personally run 75/25 mix of autogas/100LL in my 150hp O-320. Runs great, no fouling, and I save $1200-$1600 per year depending on the price difference for ~100 hrs on the tach per year. I can even run straight 87 if I want and all gas in Alaska is ethanol free, but I test every time to be sure. I'll basically save the price of an overhaul over 2000 hours.

[@GlensHangar]

@@ansonmoxness5403 That's what Chris says I could do - this engine was certified for 80/87 leaded, but that leaded gas had less lead (way less lead) than the 100 Low Lead available today and a 70/30 Mogas / 100LL mix gives about the same lead level as the old 80/87.

[@JohnUllrey]

@@GlensHangar I'm not super environmentalist or anything, but after watching this video from Veritasium , unleaded is the way to go. kzbin.info/www/bejne/f4eWlaGCr9mbeqM

[@GrizzAxxemann]

Personally, until I see UL100 take hold globally, and even when it finally does, I think running mogas is the way to go.

[@MacMiskenn]

On a note about leaded fuels, there's actually a really informative video by Veritasium about why leaded fuels are bad for humans.

[@GlensHangar]

Leaded fuels are horrible for humans and the environment, I think AvGas is maybe the last holdout of leaded fuel? A few municipal airports have banned it, and only sell unleaded MoGas, and JetA / JetB - which is a great step forward. But it leaves behind a lot of aircraft that can't legally burn anything but 100LL leaded fuel. Not everyone is going to pony up the almost $500 that I did to get a sticker that says unleaded is fine for my aircraft; regulations need to change and Ethanol free fuel needs to be available at every airport.

[@pamelabraman7217]

So Glen I knew you're not a mechanic, but what I want to know is can Chris cook?😆

[@wespotter6985]

Do you know how many total hours since the rebuild

[@jjudy5869]

Someone missed rolling positions 6,7,8 on that leading edge. How did they bond in the bracing (I think it's a stiffener but can't remember the name of the part, but can see it in my minds-eye.) and not catch that?

[@davecoleman7431]

I would love to be your mechanic you pay me 300 dollars to put a sticker on your plane , we both laugh at the price 👌

[@Puuch44]

Eff ya! We're back in the HANGAR! ✊

[@DanielWhiting]

Do you use camguard? We add it to help with the corrosion. I don't know if it actually helps but Mike Busch seems to like it so we figure why not

[@marinedalek]

Interesting that the inner leading edge profile is wrong on the "Next Time" clip. I wonder how much that's affecting the handling of the aircraft, particularly on the assumption that the starboard leading edge is all to spec.

[@GlensHangar]

I've flown just about 20 hours in it so far - and never noticed any trouble with flight characteristics. Stall speeds, Vr, Vx, etc were all within book values; so even though Andre says the edge is wrong (he'd know; 50 years of aircraft sheet metal experience much of that in the RCAF) it must be within margins?

[@M27-f4f]

Hey. Are those the old 664’s and are you replacing them with new mag’s? I need to replace mine and I’m curious if Chris recommends going with new slick 6364 or a rebuild like a Kelly 6364. Any information would be greatly appreciated since this is a 7-8k expense. Thanks.

[@GlensHangar]

We tried to replace one of them with a new E-Mag (kzbin.info/www/bejne/rX-nkJupZdicZ68 ) but that didn't work out - so I'm looking at options right now. Chris was leaning towards re-built; he seems to think that the rebuilt are just as good as new / with a lot lower cost. Probably something we'll tackle this winter.

[@M27-f4f]

Thanks

[@rogerw5299]

I just realized the pun in the channel name, Glen. Pretty sure it is an intentional pun, anyways. Been a long time since I saw a Duck Unlimited commercial, so it took me a while to recognize it.

The 'Canucks Unlimited' has a fairly long history of being used by the RCAF transport squadrons; starting in Burma in WW2, and is still used today.

[@johnmirbach2338]

🤓🖖✌️👍👌😎

[@Kinkajou1015]

So I don't get it, what does the metal ring do then? Does the engine not need any actual modifications for using non ethanol unleaded automotive fuel and it's just a regulation and cost that governmental agencies levy on the aircraft owner? I mean, if so, I sorta get it, adding a one time (hopefully) tax to give you legal authorization to use fuel not originally intended for aircraft because it's taxed differently. Sorta like how kerosene that is dyed red isn't taxed to be used for auto fuel (it can be mixed with diesel to help with winter operation) so if checked and you have red dyed fuel in a diesel engine fuel tank you likely are doing a form of tax evasion.

[@GlensHangar]

I'm not qualified to put it all down on paper in a great explanation - there are problems with the use of MoGas because of Ethanol, or not enough octane, or some engines need a small amount of lead (debated) for lubrication. Also additives in MoGas can cause vapour lock with some fuel systems, etc, etc. The metal ring just signifies that my engine / airframe combo has been tested and will work fine with Ethanol free MoGas with an octane above 90. It also signifies that I understand that I should use at least 30% 100LL to keep enough lead in my engine for lubrication, and that I understand that vapour lock could be an issue at certain altitude, temperature, power setting combos. The sticker on the panel is a reminder.

[@Surestick88]

It sounds silly to require a sticker but you know if there was no requirements someone would put mogas in a plane that wasn't compatible because they "heard from a friend it was fine".

[@kbjerke]

Will you be running premium fuel, which contains no ethanol? That's what I use in all my air cooled engines.

[@GlensHangar]

Yes - on occasion, when needed. I'll probably use 100LL AvGas 90% of the time, but there are a few airports in the North that don't have AvGas, and I'd need to get fuel in town from the auto station. So premium unleaded 91-94, and then test to make sure that there isn't any Ethanol. Based on when this engine was rebuilt and the parts put in - it doesn't need much if any lead, but it definitely can't have any Ethanol.

[@kbjerke]

@@GlensHangar Good stuff, Glen. I may be showing my age, but I really, really miss the fragrance of 80/87... (sigh)

[@sip4751]

@@GlensHangar None of them “needs” lead. That’s a old myth. I’d rather not run with lead but 1) It’s in the partnership agreement to use AvGas. 2) It’s not so easy to haul the amounts you’d need to the airport. That lead causes plug fouling, can build up at the valve seats to cause problems and is why we have to use Dino oil and change it so often. If you run mogas you’ll avoid all those issues.

[@scottstewart3884]

That MoGas conversion sounds like a HUGE cash grab for someone.... LOL And speaking of Cash Grabs.... Which is cheaper right now? Avgas or Car gas?????? I'm betting Avgas.....>GRIN

[@GlensHangar]

MoGas is marginally cheaper right now than AvGas, at least at the airports I've been to.

[@MrDdaland]

About that $300 placard. Yes, it's probably a $1 piece. But what you aren't figuring in is all the work to get it approved by the FAA, Air Canada, etc. Part of the reason small planes still use a lot of the "state of the art technology" of the 1940's.....

[@GlensHangar]

We get that - but if you've already bought the STC and years later just need a replacement sticker because you've updated the panel, or it's become illegible with age; the replacement cost is pretty steep.

[@MrDdaland]

@@GlensHangar Glen, you would think (famous last words) it would be substantially cheaper if you already have the STC, but I know that's usually not the case. BTW, I was trying to explain the reason to the non-aviation type of viewer
