- With 23 hours on the engine since overhaul, it's time for an oil change and I may as well perform a compression check while I am at it - note the large amount of carbon in the oil screen - overall compression check was good
I could sit and watch these all day...Kevin is very good at explaining the tiny nuances that most gloss over. These are often the things that make the biggest differences. Not sure, but going to look into it...if he is still active in making videos.
Great Video ..... I'm retired and hold an A&P acquired at the old Northrop Inst. of Tech. in Inglewood, Ca.(1968) .... the maintenance school is closed now but, the college of engineering is still there ......You remind me of one of my instructors whose favorite saying was - "this is how we do it in the field, and this is how you do it for the F.A.A. test"......that old codger had more work arounds than you could shake a buzz box at .................Keep the videos coming ............. JRW
Oh snap I go there now it's called Spartan woop woop.
Kevin, it was great to see you up at OSH this past year. You came by our booth with all your young Eagles in tow. I wanted to say how much I appreciate you taking your time to escort them around the show for a couple of days and explain various things to peak their interest in aviation. They will be the ones to follow in our footsteps. Blue Skies!
Nothing better than watching someone who actually knows what they're doing
Loved you on Repo! Great to see you have you own channel.
Hello Kevin, I have retired 10 or so years ago, but your videos take me back a good 55 years when just finished engineering college got my first job (at Biggin Hill aerodrome England) and worked the cessnas , pipers, tiger moths, etc to name but a few. Went on to the larger and very large machines, when I retired threw a stone over my shoulder, but the little ones are in my heart. Every time I hear a piston engine overhead I sure do look up. The jets don't feel a thing, Worked from Harriers to 747 but. Watched you doing your oil service with nostalgia, ( p s never saw a carbonised filter like that ever though, Regards
Hi Kevin, saw you,in Section 3 last year. Glad to watch this. I own an Ercoupe, and although not an AP doing my own work, I enjoy learning as much as possible.
Thank you for the uploads Kevin, as a current A&P student at my local community college I enjoy watching these types of videos on my free time! Sadly I got almost 2 years to go to obtain my licenses but I'm loving every single day at school
are you working now, and how do you like it?
Steven Rodriguez I am, I got picked up as an apprentice for a major airline and became a mechanic quick, good pay and benefits but then COVID struck so I might be out of my dream job soon.
If you can, work for a cargo airline, they never have problems. General Aviation like Kevin does is fun but there is almost no money to be made compared to airlines and cargo.
@@xbshot how’s the aviation world treating you? I start class next month to obtain my a&p
@@thax6306 I totally forgot about this comment lol. I’ve been at a Major for 3 years. No regrets at all.
@@xbshot nice! Hopefully one day I can be where you are 🤞🏽 I start class in 2 weeks
Thanks Kevin. I am new owner on an old Piper pa28-140 (1970) and my partner is pretty handy with things that burn gas as he has been rebuilding a few engines in his past. Very helpful as we are trying to save a few bucks where possible (safely). Again, many thanks!!
What a nice bloke.
I can't imagine him ever being steamed up or agitated... he's as cool as a cucumber.
Kevin must be one of the most competent blokes I've ever come across.
His repo' work really tests him at times and I've often wondered just how he's going to get out of this latest fix he's got himself into, haha.
But he always comes through it seems!
Long may you continue Kevin, we all love watching.
Kevin it`s great to see you again. I`ve subscribed and will be looking foward to some great vids from you
The build up of matter on your oil screen is strange and worrying, personally I would not be able to sleep until I had resolved what is causing that issue.
Thanks for the video, it's nice to see you again Mr. Lacey, I watched all the airplane repo TV shows.
That crud on the screen would give me a bad feeling too. Kevin knows what he`s doing and it`s his ass on the line so take that into consideration. As long as there`s no part #`s on it clean it git `er done.
Thanks Kevin I really enjoyed the video, I'm off to change the oil in my new to me airplane. Only thing to comment on is a Bourdon tube is used to sense pressure, your temp,sensor is an RTD or resistance temperature detector. Thanks again.
James Williams
Bourdon tubes can be used to sense temperature as well
So educational! Thanks, Kevin. I'm looking at a 1945 Stinson L-5 with an O-435 engine. Can't wait to start getting dirty!!
go for it Jan - leave the naysayers behind, you can do it!
Awesome videos. I was a UH-60 Blackhawk Crew Chief from 2000 to 2008. Stopped turning wrenches when I got out of the US Army. Man, after watching these videos I really do miss it. I'd love to get into turning wrenches on fixed wing, doing overhauls, etc.
Awesome videos Kevin, thanks for sharing. Very inspiring videos.
sounds like you need to go find a helicopter operator and get back to doing what you like doing
I watched this for the first time tonight and you mentioned curving the safety wire. I try not to give blood anymore!
Mags snap around 24 degrees before TDC, in which, if you apply pressure with the piston not at the true TDC can cause it to throw your prop.. also if your on the up stroke, or before TDC than you more than likely won't intuitively expect the prop to move backwards .. careful my friends
Thank you for taking the time to do this. Enjoyed your instruction.
Excellent, informative video! Thanks Kevin!
I know this may sound silly but the rings not seating or not seating quickly is sometimes due to much oil in the assembly of the piston ring package. I learned this from an old NASCAR engine builder
This engine builder used 3 drops of light oil in the ring lands and 2 drops of oil on each skirt. I was at the Dino when we broke the engine in. I took a compression leak down after 20 min. every cylinder was perfect. I then followed this procedure on my O-200 cylinders. Using the EAA engine break-in procedure for experimental's where you put your hand on a back cylinder, running engine untell cylinder is too hot to hold than 20-30 min cooling down. Timing and logging each run. took all day to get up to 5 min run. after 400 hours comp is 78/80 all cylinders and no oil consumption.
Gess, I have a NASCAR inspired Luscombe...LOL
Very instructive, and I appreciate all your effort and care in the filming.
Thank you for the video nice watching you check out your plane
Hi Kevin new too this very interesting
Glad I caught your channel. Hope see u again.
Watching your video here in Fort Worth
I hope they bring the airplane repo show. Kevin Lacey you rock sir!!! I'm adding you to my subs!!!!
Love your videos im currently going to school to get my A&P and your videos are nice to watch to see real world scenarios.
you are the best repo person ever you can do any thing
I know you from Airplane repo and love your comments. I'm glad you do videos here. I should been Texan cause I think the same
I enjoy your videos very much , thank you.
Liked the video. Down to earth.
Sweet video Kevin! You just learned me to check the oil screen on my Lycoming IO 540. Probably never been done by the looks of my logs!
God I learn so much from this man,, my dream is to take a flight with him sometime
Ha ha ha. I thought the gringos did not have old school tricks. very good those of the ring of the spark plugs...
Kevin, be on the lookout for a 182RG, 79 and newer please, I'm looking......
Very Nice. Thank you.
The item in the suction screen is not a Bourdon tube. A Bourdon tube is what is inside a pressure gauge. What is inside the suction screen is called a thermocouple. That is what senses temperature and sends it to the temp. indicator as an electrical signal.
Cool clock, always turning the runway😄
Man, I would LOVE to fly with this guy just once. Hell, just meeting the guy would be good, too.
Watch Aurplane Repo
Great video,very educational.Top man 👍👍👍
Holy smokes! Is that a Buick Regal Grand National or the GNX in the back? I used to idolize that car when I was in high school. I really enjoy your videos by the way. Thanks for taking the time in putting them together and explaining in a clear succinct manner.
Taillights look more like a mid 80's Monte Carlo.
Thank you sir for posting!
you're awesome pilot and a mechanic
thanks Kevin!
Enjoyed the video!
Good video! Well, it looks like you just need to pull one cylinder jug to see why your rings aren't seating. I fly a Cessna 182 and I'll change the oil myself, but anything else, Cessna does it. Hopefully your engine straightens itself out !
@@michaelsaint7325 are you a pilot ?
Awesome vid Kevin!
I just subscribed,I cant believe that I passed your channel over the other times it was in my feed.I always assumed it had to do with the show.But I have to say I really like what you're doing here.I cant wait to catch up on things and see what else you come up with.
I never knew copper could be annealed that way,I always assumed it was like other metals that had to be slowly cooled.
I was shown how to do that by a guy who was about 65 years old back when I was about 19 - reckon we call this 'old school'
nice vid ,, wow some carbon build up there as well i think u said chrome cylindars , i could believe they take longer to bed in
This guy absolutely cracks me up. I know the repo shit on TV is worked over pretty good, but this guy is as straight shooting no bullshit as they come. Funny as hell and someone you can learn from. And the less “politically correct” the better. Nothing drives me more crazy than doing or saying things in a different manner than you know is true and correct just to not hurt anyone’s feelings.
Great tips & would save lots of money. I don't have a plane (yet) but always have beer (=
Awesome video! Thanks for sharing. Was looking for a video with someone pulling the oil screen.
Hey Kevin I'm just watching your repo shows bloody fantastic show watched a few now back to back I'm wondering tho how do ya get ya car back after you haul ass away with the plane I'm sure there's a easy answer to this question fantastic show your a great man definitely God bless you
We would anneal drop forge die blocks, but didn't involve dropping them in water. They would cool slowly over 24 hours.
Usually harden stuff by dropping into water or oil.
Very good instructional video.
Nice tutorial! That's a good lot of carbon on the screen. So you've been using straight mineral or AD oil?
Great vid, thanks
Don't like working on lawn mowers but I do dig that Taylorcraft.
Shows up on my feed again. Still like my heavies. Gotta respect the old GA craft.
Great Stuff ,, thanks
Crzy we did oil testing on our mine equipment oil, i didnt know they actually did it for other motors as a service.
+SRT480 They do it for whatever oil you send them. You can drain the oil from your lawn mower, bottle it up, and ship it to any of these services. Provided you pay the the fee, they will analyze your oil.
Looks like it's running rich , ?? thanks for the videos
This is such a good video! Thank you for doing it.
Man. He can talk....
your a cool guy!!!
nice job on the vid.. fly with you any day
Looks like. Cool grand national in the background
Airplane repo guy Kevin Lacey cool. Seems odd one cylinder has less compression then the other three. Hey Kevin Have ya heard of use of mineral oil for break in. Then switch over to aircraft oil to aid break in of new rings? Thanks for the video
I have a Taylorcraft as well...would like to see how to remove and clean plugs.
Could your excessive oil consumption be because of cylinder glazing and a re-hone needing to be done?
Helpful video. Would love to have seen the safety wiring up close-esp as I’m about to finish up an oil change on an A65. Anyone know of a good safety wire video? And thanks for the insight on the oil screen crud. Good stuff!
Thank you for the good video
Regards
Excellent maintenance video, has thought about having an assistant apprentice, I really like civil aviation ... I also wanted to ask if the oil change to the engine does not use any additive chemical to wash the engine inside.
Hi, Kevin. Long time fan. I apologize if this has been answered before but I was wondering if there are any plans to bring back the repo TV show? And if not have you thought about hiring your own production company and releasing high end airplane repo videos on your own?
Hi Kevin
Always enjoyed your videos.
I am about to install a tempest oil filter adapter on my Cessna 150 m , so I don’t have to deal with the oil screen anymore. My question is what do I do with the screen? Do I need to put it back where it goes to only plug the hole ?with the tempest adapter I will only have to change the oil filter when I change oil .
Thanks so much for your help (answer)
Ps. I will be giving this job to A/P mechanics to do it anyway . Thanks again
Tdc is so critical when checking leakdown. I've had wrenches on crankshafts swing on me
Kevin any relation to Dads x-chief pilot UAL Clay Lacey ? or Billy Lacey
Love it thanks for the info
Thanks for this educational vid. I learned a lot!
I want one of these t- shirts!
Wish I was there while your annealing spark plug gaskets,hell,maybe I should buy me a plane so I can do my own annealing w/bud !
Did you ever get this engine to break in? I have about 21 hours SOH on my newly overhauled O-200 and it's still going through about 1/2 QT every 2.5 hours. I would have thought it would be broken in by now. About to do my first oil change. The compression check at 12 SOH hours was all mid 70's. That's when I did the prebuy. I've got mineral oil in it now. Thanks good video.
Mark Stevens I just gave away 24 cans of summer oil. Maybe you needed it more
Nice Monte Carlo!👍
That's called a cylinder leakdown test and its usually done AFTER a conventional compression test determines how well the rings are sealing IN MOTION. Its entirely possible to have "good" cylinder leakdown and still have low compression. A leakdown test also works better than doing wet/dry compression tests to determine where leaks are. Lacking a leakdown tester you usually do a "wet" test to see if oil on the rings brings up low compression. If it does, you know that's PART of any compression issues you have but it doesn't eliminate leaking valves, etc. If a wet test doesn't bring up cranking compression much or at all, there are problems elsewhere. Typically in the valves but not necessarily ONLY there. With a cylinder leakdown tester you can put pressure to the cylinder with the piston anywhere you want it do hot vs cold tests and wet vs. dry tests. Now that I mention hot vs. cold, not all manufacturers publish "cold" compression test results and in the heavy-duty diesel world its very common for manufacturers to specify "hot" compression tests.
Thank You!!
You're awesome
Very interesting but man those two on the latter did not seem too friendly. It seems they were none too thrilled you were asking questions.
How often do you have to do a compression check on the cylinders?
Great vid Kevin, how's the Airplane Repo series coming along haven't seen any new show's lately.
I wonder what the sea is it 10 w 50.
Thanks for the info Kevin I have a 7AC champ with A 65 Continental in it and that's the same engine that you have. I never know how the oil screen worked . Thank you much
I am assuming that everyone has been making their airplane payments since I have not seen any of your repo adventures lately ;) Hope to se you guys back on again soon.
sorry to be so offtopic but does someone know a way to log back into an Instagram account??
I was dumb forgot the account password. I appreciate any tricks you can give me
@Collin Willie Instablaster =)
@Jose Zeke thanks for your reply. I found the site on google and im trying it out now.
Looks like it's gonna take quite some time so I will reply here later when my account password hopefully is recovered.
@Jose Zeke it worked and I now got access to my account again. I'm so happy:D
Thanks so much you saved my ass !
@Collin Willie you are welcome :D
thats close enough! my friend got his leg almost cut off checking. compression! thats a leakdown test! as long as its no more than 20%
My calibrated torque wrench has a mark at "Tighten the crap out if it", I get a nice click at "Tighten the crap out if it".
Kevin, thanks for you demo's, I think we have compatible maintenance philosophies. Why do you use the standard 'differential pressure test' vice the Continental "calibrated orifice" procedure? bill
Is the oil temp bulb a thermocouple, or in fact is it a capillary tube that causes a bourdon tube to move in the temp indicator. Enjoyed your video.
nice little oil screen you got there...
You are the best! However, if I send you a $20 lapel mic for your gopro would you use it so we can hear you when your back is turned? It has 20feet of cable and is tiny. I personally like to hear what you are saying and know its tough doing a one man gopro camera show.
Or even a shotgun mic to plug into the camera.
Albert Adams I have looked for a mic for the Gopro, have not found one, but think I have a mic for an old digital voice recorder that might work, just have to find it and see if it works - thanks for the comments
Here you go Kev. I use something similar. GoPro HERO3 Camcorder External Microphone www.amazon.com/dp/B00CDY4O7G/ref=cm_sw_r_awd_Difnub17REMA6
Thanks Red, you should see me trying to fiddle with audio levels while trying to get a video ready to upload - I will look into that mic with a 3mm usb patch cable
+Kevin Lacey - Airplane Repo - Texas Air Fleet - "Fly It Like You Stole It!" Not sure why they are getting pissed about the audio, its all good!
OMG! How do you know all of this Kevin?
Aircraft must be different than all other engines I have NEVER done a cold engine oil change, it will effect your oil sample alot as the heavies will settle out and not make it into the bottle. And yes i know this is a old video but still.
Does that engine have an oil filter? I so I didn't see you change it and would like to have seen what it looked like when you cut it open.
As a licensed retired master plumber, "Annealing" copper requires it to be heated until "Cherry Red" and allowed to cool slowly by itself. When you quench it in water and cause it to cool rapidly, it becomes hard and not pliable. If the intent is to have a copper gasket that will crush into shape, don't cool the gasket in water.
Sorry, but you're quite wrong there, maybe you're thinking about irons and steels... but copper does NOT harden at all when quenched.
Quenching copper doesn't change the cell structure at all when quenching, unlike steels.
If you feel better by leaving it to cool down that's entirely up to you of course, but if you imagine you're avoiding hardening, then all you're doing is wasting your time.
In fact, quenching with a water dunking gives the added benefit of getting rid of most of the oxidation caused by flame annealing in air. When you dunk hot copper into water, the flaky oxidation simply shells off and leaves a pretty clean surface which is much easier to clean up, when compared to just leaving it to cool on its own.
See this:
www.materialseducation.org/educators/matedu-modules/docs/Work_Hardening_and_Annealing_of_Copper.pdf
Take a look at the bottom of page two, where it says "A few notes".
I could have added much more proof, it's not difficult to find as the process is often misunderstood by even experienced metal workers in different disciplines.
About the only way to harden copper is to work harden it, either by being stressed/strained in service, (pipe bending for example) or by hammering (Planishing).
(Basically, some kind of physical compression).
To a smaller extent, bead blasting does cause a little surface hardening, as does vigorous wire brushing, but these methods do not impart 'through hardening', they just cause a thin superficial hardening.
And in case you do some research and reply.. yes, I do know that there is an ultra sonic copper hardening treatment too... but that's extremely specialised and will not ever be encountered by anyone simply annealing a copper washer in a workshop...
Also, if you heat and then leave to cool in air, the metal (Ferrous metals and some stainless steels only) are said to be 'Normalised', not annealed.
True annealing requires the cooling to be slowed down as much as possible.
This is often accomplished by allowing the annealed steel to cool down by completely covering the metal in dry sand. Sand boxes used to be a common sight in metal workshops in days gone by.
Or, if annealed in any kind of oven or kiln, simply leave the metal inside and allow the oven/kiln and contents to naturally cool down to room temperature.
Geez. My more than 60 years as a licensed plumber and heater, and the years I spent in metal shop in Junior High and High School must be all wrong.
When we in the Pipe Trades want to put a slight bend in a piece of hard copper tubing,, we heat it up until it is cherry red. When you let it cool down naturally, it becomes soft and pliable. If it is still very hot and you cool it quickly, it will be as hard and unbendable as it was before you started. In Junior High School metal shop, we learned how to make copper ash trays in a wooden mold. The first thing we did with the piece was to heat it up to "Cherry Red" and allow it to cool naturally. So it was malleable and could be worked. Once it was "worked, we took the finished product, heated it until it was cherry red, and cooled it rapidly in n water. Once cooled, it was hard, with no oxidation inside or on the outside.
I don't care what Kevin says. He's misinformed.
When you anneal copper tubing and make it soft so you can bend it, if you install it in the North and it freezes. it will expand but usually not split where the annealing takes place because freezing will expand the tube from the inside. You can't get a fitting on it to solder. If it is a hard piece of tube, un-annealed, it will split. Take a 12" piece of Type L Copper tube. Try to bend it. You can't easily. You have to heat it up until cherry red. Look inside the pipe as you heat it and notice how the inside glows red then yellow. Let it cool by itself. You can bend it easily. Heat the bended area until it is cherry red, then cool it rapidly. Then, once cool, try to bend it. You can't. It only works with copper in this way.
Those Spark Plug Gaskets that Kevin was talking about, I don't know if they are soft or hard when they come new on the plug. If you can easily bend them, they have been annealed and are soft. If they won't bend and you take one and heat it until cherry red, let it cool and it is pliable, it is now annealed. The intent is that they are pliable and will crush into the shape of the surface. That's one reason why Type "K" copper is thicker and used underground. While Type "L" is used above ground. You can but both as hard and soft copper. Soft in a roll, or hard in a straight stick. Copper wire is also annealed, so you can bend it. The plug gaskets I see are usually like a split "U", open on the inside and closed on the end.
IMO, to re-use Spark Plug gaskets is the ultimate in cheap and poor practice. Sort of like running 87 octane no lead auto gas in your high compression air craft engine. You can do it, but it isn't a good idea if you get detonation while climbing to altitude and you lunch a piston. You better have a nice place to be able to safely glide to and land at.
Try it. You'll see.
when I pull my motorcycle engine apart the solid copper head gaskets are stiff. If I heat them red hot and plunge into cold water they become soft and can be reused.
I've been doing it for years.
If you don't plunge it into cold water, it will be softer. Trust me. 60 years of playing with copper says that's what is meant by annealing.
If you make a steel blade and want it to be hard, you heat the blade until it is cherry red, drop it into oil and pull it out. Then watch for the turquoise colored line to drop to the very edge, and quench it in oil again. Why cheap wood chisels get dull when you keep sharpening them improperly.
Post a video of that process. But get ahold of me first and give me a private screening and its its legit I'll be your agent and we'll both be rich when you're the new "Bill Nye the Science Guy" doing impossible things instead of just talking about them,
