Could work!

ihdieselman basically at this point it would need a engine overhaul

That is why when you start any engine The oil must get hot enough to get rid of the Moisture. A lot of Pilots that do not know any better go out to the field and start there engine and start it for 5 min or 10 min. then shut the engine off. OMG they are killing their Engine little by little. No one tells pilots not to do this. The A and P should be telling the Owners. That is never happen as most or 99% of the A and P's do not know that.

Yep

@@ctsteve1967 Yeah, if you have any sort of vehicle that's started only occasionally, you need to run it 30 minutes or until the oil gets up to 180F, when you do start it. Not getting the oil to full temperature is worse than not starting it at all.

that's very true.

How true...you can’t even spell airplane!

@@johnorchard6158 hahahaa yeah but he is completely correct. Put it back together and find extra parts when done!

Ya it has me cringing too many people doing different things tossing parts on the floor...

Agree

@Dillan Baker Why not, I've been a "Shadetree Mechanic for over 40 years and do good work to a high standard. Key points to Teardown are 1) speed, 2) do no damage, 3) look for clues and other problems. After this is cleaning and inspection, and the last part , assembly, is where the skill and knowledge make you money and make a happy customer.

@Dillan Baker Thus speaks a man who has only been paid by the hour or has a yearly salary. Get paid by the job and you don't faff around on the less important bits. Time wasted is money lost. Oh, if I wasn't good or I was doing it "Wrong" I wouldn't have generations of repeat clients. My best is a Granddaughter so far! Just a child's bike but the trust is there.

It's a comedic tragedy... and a disaster waiting to happen. Please don't work like they do.

@@scofab Yep, these old boys are going to kill their customers, shocking trade practices.

Maybe we will

Yikes !

That depends on whether that sign off was twelve flight hours and, say, sixty months ago.

Agreed

A&( can't sign off an annual!

@@DHMovie100 A&P can sign off 100 hr inspection, IA for the annual.

@@GrummanPilots Is it legal for an A&P to do the work *with* an IA and the IA sign off?

It had happened

ok

Long hours sitting in the weather, that evidence of water in the oil would not be restricted to just that problem. I'd bet there's extensive corrosion right through that plane. I would also never pull a cylinder without a complete overhaul after such extreme compression loss, it's just asking for trouble, but looking at the rest of the plane, it should be a scrap job anyway.

@@alasdair4161 Cars Engines also sit for years and years and years.

@@alasdair4161 There is a reason for the broken rings or rings.

Yes

No respectable outfit in the business of aircraft maintenance would allow that many hands to touch an engine, certainly not casual passers-by and none would allow a picture of a claw hammer in a maintenance cart to make it as far as youtube. Cripes ahmighty, they're terrible.

OK

Pretty much. It was eventually trailer and got to a new home and is in Paint shop now for finish. Nice plane now. Lots of love and money and time.

Glad you liked it

No worries, fly safe.

It was restored

yes he must have left them inside that last engine rebuild ???

@@WayneCook306 Eh they're just the 10mm sockets. 1/4, 3/8, 1/2 drive 10mm sockets just disappear into the ether.

claw hammer?

@@johnaustin6673 These boys are living proof that Charles Darwin was right!!

I have not much idea what I'm looking at but the mechanical skill really seems to be lacking. Don't work on my aircraft. :-)

Or mine

It did come off and get overhauled. FYI

@@GrummanPilots Oh I imagine. The ole gal deserved (needed) it. Great video.

Shaun Olinger Did you happen to notice the ignition system? At least on the right the ignition leads were disconnected. Nothing would’ve happened as long as all leads are disconnected. But I agree it’s a good practice to watch the prop and ensure the keys are removed.

Maybe

Could have been

All he needed to do was pull the cylinder off or there is a lip on the crankcase end that allows you to pop them out

ok

Glad you liked it

as a retired mechanic, I agree, that engine should be completely disassembled, inspected, cleaned, repaired and rebuilt to specifications.

Time for a major overhaul. Those in the know realize what that means.

Norbert Siewert $$$$$$!

Yep

Overhauled and restored

Maybe

With a title of 'Cylinder Replacement Gone Bad' you were expecting something different I say.

I was waiting for the pipe wrench. With a cheater pipe.

OK

Great idea

I have been less than impressed with the A&P mechanics I have encountered. I'm a master tech at car dealer, we have A&P mechanics(as customers) that can't put a water pump on a car. I wouldn't trust them working on my plane. Which is why I went experimental. S repairman cert makes sure my kitfox is in good hands.

Kris N real shame

@@krisn8820 aaaaaaaa

Thanks

Cannot be too careful.

All good points, not all owners are so stringent.

No parts left over, put it back together for trip on trailer back home.

They stick the left over bits down the carb! Lol

Ebay!!!

Nice

Been told it was a great learning tool, and Grumman designed her to be simple, safe and with little automation so students would get used to a higher work load and greater speed on installed power . Kinda like teaching a guy to drive on a 5 speed mg, rather than an automatic toyota.. manual tank switch, higher performance, the student would come out of the syllabus more confident than on a 172, or a Cherokee.. it doesn't coddle the student, and they can transition more easily to older aircraft with less automation, or higher performance aircraft due to it's own higher performance,.. Strikes me as a good investment for a flight school. I think this was Grummans philosophy when Roy LoPresti modded her up from Bede's design..my opinion they should have sold her abroad as a military liason/ trainer instead of breaking into the saturated us market.. India, South East Asia, South America would have been great markets for this plane. give it some more power and range and it would do very well in Brazil..too bad to see this example in such bad shape..

Yep

Yep

OTTO runs for a long time even broken.

yrp

Yes a design flaw but if you fly it alot not really an issue with no sitting.

Comes in handy

ya think

Yes

Yep

ok

OK

Exactly, yet in the last month 5 people did buy without a prebuy just to get their hands on one.

And to thing these idiots work on this plane it’s scary id never let these idiots touch a wrench.

This plane was restored

OK

Why silicon?

k

That tells you almost nothing about what wear is occurring, when and at what rate. If you want to track things like that try pulling oil samples and having them tested on a regular basis.

k

@@deeremeyer1749 Yes but in this case I'm just interested in the engine shedding significant amounts of metal, and on Lycs it's slivers from the cam lobes and followers. Sending oil out for analysis is a whole other level.

Sorry that fun makes you ueasy

@@GrummanPilots - just glad I’m not the pilot. Have fun!

Grave Danger? Is there another kind?

OK

Yep

Good luck with it, they are well engineered and will last a long time.

@@GrummanPilots It's a cute little trainer, getting my ppl this year in it (half way there :D )

Airplane costs are more than cars, so you are right.

Someplace not flown

Good to know

No

No but redone now.

20:18 carbon deposits on the piston tops may have contributed to ring damage. ?

Rings do break.

It was overhaled

Owner had a low cylinder and we had a spare, was going to put it on, but engine was done

In the latest video

Now about a plane that flew here.

Time between overhauls is based on engine hours not decades tied down in a field. Light use may also allow oil on internal parts to dissipate and allow moisture to get at that metal. Time based atrophy takes a tole, like the Corvette a mother was keeping for her now deceased son driven less than 100 miles a year since the 80s. Just damp winter/spring/fall cycling outside can do that given enough time.

by the color of the oil looks like a lot of water is in the engine.

Plane restored, engine redone by Lycon

NO!!!! I don't know what the boxes on the firewall we're, looked like regulators or something similar, but they sure as HELL should not have looked like THAT! This poor airplane needs a better owner!

Far from normal!

NOt with regular use

It came to us, not maintained by us.

Thats why you should only fly planes that leak oil, they never rust!

Looks like a lawn mower engine

fucken claw hammer

That's what I thought, a brass drift would had been better.

i agree..

@@aramirez8427 and I thought I was the only one to notice that! hahaha!

Yep

I'm not an airplane mechanic, but I fly them - in all areas of aviation, there is somewhat of an attitude that if it ain't broke, don't fix it. This may sound lazy, but there is actually good data to show that messing with things too much CAUSES more problems than it prevents. That being said, there are annual inspections which are mandatory, and depending on how particular your local mechanic is, a plane could find itself in the condition as seen in this video. There are some modern methods involving engine monitors and oil analysis done at time of oil change that can prevent the issues shown. Another cost to worry about for sure, but small when you are talking about the safety of you and your family.

Snob

@faa inspector- who lets their engine get that bad. think they should be working on that?

Utter nonsense. There are replacement requirements based on hours of service for some equipment, as well as mandatory maintenance requirements in every planes POH. Every plane owner I've ever known have been uber anal about the condition of their planes. @@jsteiger2228

I bet It would not surprise anyone if all of them present had a hand at various times in the routine maintenance of that POS..

Restored now

Thanks for watching.

The easy past is the wing off and wing on about 2 hours for all of that. Scrapping the old sealant out, cleaning and then reseal can take several days.

@@GrummanPilots thanks I was just checking my engineer took 24 to 26 hours , and I found another engineer saying you don't need to take wings off you take panels off then remove the tank it takes 14 to 16 hours all completion.

Not what I could see in the little time available, you would be able to tell pretty quickly by rocking the prop anyway

replaced at engine overhaul in a few month down the road

It was not now

No, HF

Yep

Yes

Glad you saw the hammer, was it the orange or yellow one? All my good hammers were outside the hangar being used by other mechanics on their work. Thanks for watching.

Yep

Glad you liked it

Yes we both do and the Airframe portion as well as the Inspection Authorization as well. FYI

Yep

Not needed yet

We are

That way you have a good plane to use

OK

It was

Yep

...;yeah...shoulda' used the stapler.

Not now

I have built and tuned bike and car engines all my adult life and I was surprised at this remark, surely you want to find the nasty before the thing is in the air?

I don't think they maintained this plane. They found these issues as they were fixing the #3 cylinder. This airplane needs more than an engine overhaul.

ok

I think some of y'all don't understand old-guy humor.

OK

with your Money Right

New owner did, see video

It is why the cylinder last most compression, broke while running.

Exactly information you get, in how not to maintain or work on the Aviation Industry....

k

Yes all issues

What you see in the video is a one-off at a maintenance event just seeing if a cylinder change would gty him back in the air a bit safer. Not a paid operation. Normally we work like you think, but this was an event and Ken was filming so folks gather.

Glad you liked it

Doubtful it ever will, limp home is not a good mode at rotation.

Why would you need a VTEC when airplane engine operates at a very small range of power setting. VTEC is for automobile that operates from idle to WOT and back time after time. If the automobile operates at 75% - 100%, then VTEC is a waste of mechanical complexity.

No

ok

Cables were fine, engine now overhauled.
