Lycoming 320 Engine Failure
Today, we disassembled a Lycoming 320 that experienced failure. This engine was a high hour engine, so something going wrong was to be expected. Sure enough, after having taken the engine apart, I noticed significant wear as I went on. Excessive wear on one particular valve stem after pulling the rocker cover. Aluminum material in the oil pan, and ultimately a broken lifter and broken piece of the case.

Crap music
Cases are out there, usually a case goes for about the same as a crank. But that's for a used yellow tagged one. If it were mine, I'd find a case, and go with that to get it back in service. Have it overhauled and hope it doesn't go under. Or if it dimensionally checks okay just put it back in service. I had one overhauled at Divco, came back red tagged due to being too thin. Had to find another one. That's one thing they guarantee, that is the case is good. If not don't buy it.

good job
1930s technology.
Certainly the case can be heliarc welded and machined to resuse it. I'd be replacing all the lifters, pushrods and maybe the rocker arms on an engine that old - while you are in there it's a lot cheaper than dealing with it assembled and giving you problems Am sure you can exchange those cylinders for rebuilt ones and put new pistons in too
I worked in a part 145 engine shop. Tore down over 100 engines, some had rods thrown through cases, many prop strikes, etc Make sure to use compressed air to blow out oil holes in pushrods, they’re often plugged with sludge and starve corresponding rocker shaft of oil A&P/IA
Nothing about that rubbish looks reliable buy a horse.
Get more tables they sell them at Sam's Club Walmart and Lowes ❤😊
Nice video
Where are you That Pilot Guy?
not alive anymore. crashed with this diy fixed engine.
@@user-th7gd7ge4p What! That is so sad 😢
What happened with this UA-cam channel?
I guess this is a typical cause of full power on cold engine! Consider the first 40 sec there is no lubrification in the valve lifter channels in the upper and outer part. Mike Bush teaches one start < 5° Celsius is 500hour airborne! If oil is warmer than 60° no metal part is touching!
Music makes this unwatchable
I know this is a older video but first time for me as a a&p who has overhauled many of these Lycoming engines this is the second video I have watched case damage inflicted by improperly separating the case . Read the manual there is a tool to press it apart using wedges will damage the case lucky it was a easy one to get apart . Huge mis information on this teardown .
Had to stop and find a better video,can't go the music dude..90% of vids are ruined with music
Take a x30 or more pic of the broken metal, great info. Thanks¡¡¡¡
It most likely was a human induced failure. The lifters used there are solid lifters not hydraulic. Therefore they do not automatically adjust the valve clearance. So if they are not installed with the proper clearance they can have excess load placed on them by the camshaft. Causing stresses inside the lifter. Engines because they are old dont just fail. they technology in these engines are 50s and 60s.
If you're doing a major overhaul you don't need to keep any of that stuff separated
I like to watch stuff being disassembled; I do not like loud, annoying music soundtracks.
is there a workshop in usa that offers engine owner to overhaul his or her engine and thereafter getting certificate to legally do such overhaul back home ..for me in KL,Malaysia? thx
I am an audio engineer. I can edit the audio of your future videos, and I have never offered that to anyone else. lol.. but you certainly remind me of a younger version of myself and I really did like this video a lot. By the way, I would not buy half of a case for this repair. I would definitely buy both halves because the bearings need to be exactly married and I just wouldn’t trust it. I have never messed with airplane engines before but I have overhauled car engines and I’m just starting to mess with airplanes now. Looking forward to more aircraft Content. Good luck!

Whats the name of the band and the song that theyre playing during the teardown montage? Its sounds great. Love it. Anyone know the answer?
is that a love bite on your neck 🙂
birthmark. I get asked that all the time
@@thatpilotguy4995 nice! Hope you have time to do more videos about airplanes, flying, engines etc for us in due course!
My heart skipped a few beats when he removed one half of the crankcase and left the other half unsupported. I could imagine it flopping on the floor with a loud, expensive clang. My old boss would have my guts for that. For starters,
As a backyarder that's been building and tuning engines for 40 years, it never ceases to amaze me how an engine can find a way to destroy itself. I see a solid steel lifter that is supposed to be only under compressive load, have so much side load that it breaks through the case and snaps off. Mind blowing for such a relatively low revving engine.
The cam lobe engages the lifter from the side.
The amount of dirt in that thing I'm not surprised , I would say the lifter seized and then the cam pushed it any way it could, being old if it had some play in it then it may have locked sideways . But this could be a lubrication issue that had it run a little dry in that part . Chuck bottle of lifter turn up in it It'll be fine.
As the cam lobe swipes sideways over the lifter, it does impart a sideways load on it
Are you an A&P ?
Thank you for doing this video. I fly an RV9A with this kind of engine, i understand the stick drawing of how an engine works but , seeing you take it apart was really an interesting visualization. Also the casing failing with the lifter that is pretty spooky , did you say how many hours?
the music is WAY too loud, especially compared to your speaking voice.
Liked the video but the music was a distraction.
Hella interesting. Thanks for explaining in detail all this stuff.
This engine is only fit for the scrapheap. Not worth to repair or to overhaul.
I never knew why they did not make these engines water cooled. I look back at my Volks Beetle with that air cooled engine. I overhauled that thing 3 times and I am sure it was because of the heat from being air cooled that killed it.
is it overhauling ? A320?
Instead of TBO - i have seen good evidence for aero engine, oil sample/trend analysis and on condition OH only - most issues happen RIGHT after OH as well.
i have a robinson r22 beta project not started in 20 years. the goal is just to fire the engine. should i start by removing the carb and cleaning it?
What was the TSMO on that engine (if it had one), and TT?
was thinking of a Beetle with a Lycoming Flat 4 Engine instead of its tiny Flat 4 engine 🤣
....because it was old. Saved you 14 min.
Thank u for your inspiration, knowledge and experience.
I think a torque adapter would be easier to use instead of the crows foot for the cylinder base nuts.
10:10 Where u get those orange wedges?
how many hours?
The horizontally opposed aircraft piston engine is long overdue for reengineering. The heavy rotating mass, torsional flex, ancient aluminum and iron alloys utilized, harmonic resonance, and crank case reinforcement, all need a rethink.
Sure. It's called a turbine.
@@nycchris8743 It's called Rotax. Turbine are too expensive for small applications silly boy..
The comment has nothing to do with cost. Inexpensive, or not, Rotax engines use pistons. Read the original comment. My comment still stands. Silly boy.
You are right if cost is not a consideration. Silly Boy.
Great Video !! But the music got to go !!!! MY OPINION
The music was awesome. Love that bluesy piece during the teardown montage. Anyone know the name of that song?
