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
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!
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
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
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.
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.
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.
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.
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.
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
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.
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.
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
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.
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.
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
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
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 !
+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.
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?
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.
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.
Kevin Lacey, you crazy sum ma bitch you...Man great to see you on You Tube.. You still with that former airport executive that was on the show once...Anyhow, glad I found your channel Boss!
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
@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.
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!
8-10 tpi with .032 Kevin. 9-12 tpi with .023 I always pigtail, too many sliced open hands and fingers. Good knowledge, thanks for sharing. p.s., is that a Grand National?
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
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.
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
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
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.
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
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!
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.
I think that the reson you needed to "tight the crap out of it" is that you are using the wrong gasket, or just poor gasket. I also recomend using safety gloves when handling safety wire, just in case it snaps...
kevin, first, its a pleasure to see you around an aircraft again. Im a pilot as well and want to know, Is there any draw backs to a mechanically inclined individual doing a per-purchase inspection using some of your tips and techniques..ie youtube videos
