Dude, your meticulous and careful engine management probably prevented a more serious in-flight failure, with your family onboard. I believe $16k and peace-of-mind is waaaaay better than an off-airport landing in a field that might total the aircraft, and cause injuries or worse. I had a valve break in flight, punched through the top of the piston and into the crankcase. I was lucky to make it to a nearby runway.

[@stevecunningham6821]

Only in aviation would an engine overhaul of an engine that was designed in the 1940's would cost $20k (don't forget the cost of removal and reinstall after the overhaul is complete). The "everything is justified cuz safety" is not really the virtue you guys think it is.

@@stevecunningham6821 Not only aviation, boats too! It's the same pattern: "This is known to be an expensive hobby, so let's just make our product 3x as expensive as car parts!" Unless the rate for planes is 5x 😆

[@thomasrosenbloom8566]

Some perspective here might be helpful. From someone who has been in the maintenance industry for some time, your pro-active approach paid off! You found the problem before it became a failure. This is one of the two primary goals in maintenance, the other being to schedule your downtime rather than encounter it. So while I understand your disappointment, and concern with the expense, in truth your efforts really paid off. And they will continue to pay off in the future. Bad luck with one set of components will not necessarily translate to better luck next time, but a superior maintenance approach will ALWAYS yield better results over time. So take heart!

[@edanford]

I experienced the same issue with my IO-520bb 10 years ago. New cam shaft and lots of money spent but ended up with a solid engine that has lasted ever since. Better to find it on the ground than in the air for sure.

[@zackmorrison1392]

I’ve been working on aircraft for the last 25 years and was employed at an engine overhaul shop for about 10 of those years. There isn’t much you can do about the cam problem. Lycoming has had cam problems since they went away from full lead in fuel. The engine and components were designed with that lubricant in mind and they didn’t work as well without them. The new lifters are an improvement and you can also look into the centrifuge-lube camshaft STC that gets oil to the cam and lifters as soon as you have oil pressure.

[@MarionBlair]

How did the lead reduce Camshaft wear?

[@deani2431]

How can lead in the fuel lubricate the cam???

[@fredpinczuk7352]

Yes, how does that even work? @zackmorrison1392

[@MarkNewtonFlies]

If you have enough fuel near the camshaft to use tetra ethyl lead as a lubricant, you have some much bigger problems :)

[@TonyManzo-w6m]

100LL has 4 times as much lead in it as 80 did.

[@guyshilon2807]

Great data about GA aircraft’s. And the delivery is very informative and fast to comprehend.

[@jeremynoble6715]

I feel your pain! I just had the engine in my 182 overhauled and less than 200 hours later I found metal in the filter - turns out several lifters were spalling. I do the exact same things as you to try to avoid corrosion, including an engine dehydrator. The only thing the engine shop and all the mechanics I talked to could come up with is there was a bad batch of lifters sent out and I probably got some of them. Luckily the camshaft was ok and they threw in new lifters but at this point no one is sure if the cam will eat the new set or not. It’s super frustrating, stressful, and expensive - but I wouldn’t trade all the adventures and memories we’ve made with the plane.

[@djbowe]

A $16K repair is far better than 16K feet engine failure that results in a crash! Well done on your meticulous care of your aircraft. Look forward to more adventures with your family!

[@craigwilliams2858]

I have followed your channel for a while and have really enjoyed your content. Its been interesting to watch you from the start 5 years ago, going through the process of purchasing a plane that was cheap and then pouring all the money into the upgrades and maintenance, to get the plane in the shape it is today. Keep up the great videos. I've been in the airline business for 25 years (flying the airbus for the last 16 years) , I have learned that its not bernoullis principal that makes airlplanes fly its Money. 😄 Which I'm sure you are very aware of. Good luck on the engine!

[@SoCalFlyingMonkey]

oh yeah most definitely aware of that! I do love the simple airplanes like the Piper Cherokee- they are usually not that expensive to maintain, at least relative to many other planes. But it still seems to always be something that it needs- usually nothing major - tires, alternator, spark plugs, a new battery etc. It's such a bummer when a part like this doesnt perform as it should and it ends up costing a lot!

[@tropicthndr]

Just picture a drunken sailor in a strip club, thumbing bills at the dancer all night. He wakes up in the morning going why why, why did I do that.

Sir, I have recently become interested in private small airplane aviation and just discovered your channel. I must applaud you for your maintenance ethic. I have a 40 year experience of high performance automotive engines and have experienced the disappointment of a low mileage, broken engine myself, a number of times. Nothing is more important that the safety of yourself and your loved ones. Whatever the cost in monetary terms, your safety is paramount. I have learned myself, that the joy of having done the job properly lasts many time longer than the pain of paying the bill. Fly safe! ( I've subscribed to the channel.)

[@brettsouthall357]

I feel your frustration...I had engine failure (thru a rod) few years ago had local, well known engine shop do a SFOH and got a 0 time engine...all for 1.5x what I originally paid for the aircraft. 130 Hours later, had an oil filter full of aluminum...took back to engine shop and they replaced piston pin and pin caps in #4 cylinder. 65 hours later, and same issue. It makes me question ownership, quality of our engine overhaulers, and quality of parts. Just dropped the engine off this morning at the engine shop, hopefully, they find the root cause this time and stand behind their product.

[@jeffwiggins8923]

I had a similar experience. I purchased a Piper Cherokee 180 with about 1200 hours on the engine. I thought we had plenty of life left in it. First oil change we noticed metal in the filter. We decided to run it longer thinking maybe it had just made some metal due to the plane sitting for awhile before i bought it. But same thing came up at the annual inspection. 1300 hours on the engine. We pulled a cylinder and sure enough the cam was wearing off so we sent out the engine and got a full overhaul done.

No joke: just today I got quotation for a new camshaft after nearly 9 month of intensive search around the globe!! So fingers crossed and your plane will be in the air again this spring (and mine hopefully too) BR! 👍👍👍

[@danpage7380]

Just hopped on the same boat as of Friday - 5 years and 700 hrs and a failed camshaft. Compressions were not great which is why the cylinder was pulled and the camshaft inspected. I'm opting for new cylinders - that makes a total OH/factory rebuilt most likely in my case. Haven't completely determined the cause of the camshaft to fail, but will be adding an engine dehydrator to my hangar just to make sure I'm doing everything to prevent corrosion. I think you got a deal at 19k - I'm looking at several times that...and months without an airplane!

[@kerryeff407]

I used to build Import and Euro vehicles for track racing. I was extremely particular about maintenance and monitoring engine wear to catch issues before they became a massive liability. However, on a few occasions, I encountered engine issues (especially with the Euro vehicles) that would occur for no particular reason besides potential parts failures. Thus, there would have been nil preventative maintenance that I could have completed which would have prevented these issues (cam lobe wear, chipped valves, etc). Manufacturing issues occur period. There is nil reason to beat yourself up over issues beyond your control.

[@alexdiersen]

Appreciate your in depth analysis on the plane. Im interested in getting my private pilot, but also ride snowmobiles and motorcycles.

Fellow 6 owner for almost 20 yrs. I’ve been through a “top end” when I acquired the plane, a planned full overhaul at TBO, a “partial” teardown/repair (stuck valve) and most recently an “IRAN” 1 1/2 years ago due to metal from a gear in the accessory case. I hope $16k holds up for you, but brace for more …

[@cadmanchannel]

Generally, cams are lubricated by splash/fling, and with the Lyc, the cam is above the crank. Idling lubrication is the worst in this case, and there is a lot of idling going on with small aircraft, so you are kind of screwed there. Starting an engine is what kills it, as there is less oil where it needs to be, and it takes a moment to arrive there as it is thick from being cold. Some Lycs use a single lobe to operate a valve on each side of the engine, accelerating wear, but I don't know if that is the case on your engine. Good luck!

[@turbowidget]

I have rebuilt literally hundreds of engines, mostly non aviation, diesels etc. and there is no engine out there that is free of this kind of failure. It is usually down to a flawed hardening of the parts but can also be triggered by improper valve lash / hydraulic lifter failure causing the lifter to “slap” the cam. I watch my IO-360 continental like a hawk but i do know there is nothing you can do about mechanical wear and tear. We have to accept the hits to play this game. It is ironic that your video posted today as i am currently changing a camshaft in my daughters chrysler 300 for exactly this failure. Two lobes gone on right head camshafts. It sucks but caught early as you have saves a much more expensive engine failure.

[@cardoncarl]

Dude $16k is a very good price. On a Piper Saratoga II HP, during the annual last December, the mecanic found corrosion on the camshaft. I receivre a $80k quote to take the engine out and do the overhaul... IO-540-K1G5.

[@quinnjim]

I bet your cam shaft was not new when they rebuilt the engine. If they inspect your old one and it checks out OK, THEY PUT IT BACK IN! The problem is the old one might be about to go bad (with the outer coating barely thick enough to go on). Even a factory overhaul often has used parts reinstalled with thousands of hours on them. It’s a real shame when you do everything right and the engine doesn’t get close to TBO. Really sorry to hear it.

Hey! I just had my cylinder need an overhaul in October as well! Then when they were done or thought they were they were still losing power so they dug further and found my mag harness was bad on the one side....so, replace BOTH sides! Hey...ugh Then they checked the air intake housing and it was broken needing to hit up an aluminum welder. My bill was 6300 for all of that. I got it back at the end of october, didn't get to fly it until the end of December and first flight in I lost my audio coming in so it just went in for a new audio panel, harness and while it was there get the Prop eddy current done and the bi annual IFR certification. I would guess I'm in the 4k range to be fixed now. It hurts and I only have a 4 cylinder plane. That's 10k plus in just 3 months. It's definitely the life of the plane and if I wasn't debt free I would seriously be hurting!!! You will get through it, one repair at a time.

Watching your video was like a repeat of the exact same thing that just happened to my engine. I have a 1975 Cessna 180. I do the exact same things you do for engine, maintenance, and operations. I had my number five exhaust lifter fail, and destroy the cam this last winter on a four year old, 209 hour engine. The engine was hooked up to a dehumidifier that turned out not to be working. The hangar that it was in was extremely humid, which is why I purchased the dehumidifier in the first place. After several months of investigation, I realized that it was pumping moist air into the engine all winter long. $16,000 seems pretty expensive for a cam and lifter replacement. Mine was $10,000+ removal and replacement. Sorry to hear about your woes, I feel your pain! It would be great to chat with you in depth about this. Get in touch if you would like.

[@jimiemick]

As someone who has a brain that makes me dig deep in to why things happen, I get your frustration, Even more so when i have 20+ years experience with engines and mechanical equipment It can be hard to just sit back and accept that bad things happen, But on a positive note, the bad cam/ Lifter was found on the ground, not in the air. Just sit back swear a bunch (if thats your thing) or crank some music.

Hi Eric, greetings from New Zealand. I have the same PA32 IO540K1A5 engine. I had my engine: shop rebuilt 2007. I have since completed 2200hrs all LOP. I installed an oilamatic pre oiler. My engine rebuilder Gary Blythe has an STC for the Lycoming camshaft he used for my engine, called "camshaft pressure lubrication". Unfortunately FAA don't recognise this STC. Gary has done over 800 cams for NZ and Australia. The STC involves blanking off both ends of the hollow cam and drilling a hole in each lobe. The cam receives oil through the bearing journal. Cam wise I have the best of both by pre-oiling the whole engine before cranking plus the cam STC. Gary thinks it maybe possible for your pt91 to achieve a sign off for his cam mod. The oilamatic company was sold after my purchase and I understand the new owner did not get the STC's. Peter

Yeah this is absolutely wonderful to be caught by your excellent mechanic now instead of later. Thats a small price to pay before it got worse or caused you to end a trip in the middle of nowhere. You should be happy for the way this went. Yes i think whoever rebuilt it should've put te new style lifters in but now youll have them on a new cam.

As a fellow airplane owner I constantly live in fear of stuff like this. I feel for you.

[@colelindenfelser3374]

We have the exact same situation going on with our PA32-300. It had 150hrs on a 10year old engine. We chocked it up as sitting too much prior to our ownership of around 2 years. I'm interested in this new coating I'll have to ensure our engine shop is using these new components. Thank you for your devotion to the general aviation keeping viewers like me amazed with your skills every video you post!

[@theflyinglife1]

TBH, I'm shocked its only $16k + R&R. That is all in? What shop?

[@ronaldvanengen1887]

The acronym of Boat applies here!! When it comes to Boats and Aircraft Bust out Another Thousand If you don't have Thousands u shouldn't have a Boat or plane!!❤😂

[@steve.e.may87]

Your scientific approach to airplane ownership (and documentation thereof) is second to none. You removed as many variables as you could with the tools you had. Thank you for the exquisite content over the years! Here's to hoping to see more.

I own an airplane and a 39’ Trawler. The boat maintenance cost is at least triple the airplane. Marina fees, bottom cleaning, general maintenance. I spent 20k on an engine rebuild ( insurance paid another 20) after a storm forced water up the exhaust and into the engine. You got to pay to play. My attitude is you can’t take it with you, so spend the money and don’t agonize over it.

[@pppeeettteeerrr]

Your mechanic definitely knows what he's doing, glad this wasn't "discovered" in the air. Surprised to see this type of damage since your motor doesn't get "beat on" like a training plane... but over time aside from the cash flow hit the numbers will all even out... Seems that $100k for motor+unscheduled maintenance over 2000 hours TBO for a 6cyl is a good number these days.

Yeah he’s got an eagle eye for detail stuff. He called it and was spot on.

Lifters go bad for no reason all the time in the automotive world. My dad and I rebuilt a 1974 Corvette with a 454/TH400 combo back in the mid 90’s. Not soon after the engine was rebuilt we started getting some noise. Turns out one lifter went bad and the engine had to be gone thru. Luckily the lifter manufacturer warrantied it at no cost to us. It just happens I suppose.

[@airfiero4772]

Even though we have engine monitors, borescopes and advanced maintenance techniques, our planes have 40-plus-year-old engines which are 50-60 year old designs (or more). As long as the processes like STCs are so expensive, we'll be dealing with this old technology.

[@lars808]

Oh no, im sorry this has happend to you. I am a beginner Private Pilot who is renting, and i wonder if including events like these, the cost still break even with ownership. I dont know what the prices are for renting in California, but here in Germany its about 230$/h including gas, maintence, hangar and everything else. I guess the Factor of having the Aircraft available to you at any time rather than beeing dependent on rent availibility is priceless though. Greetings! And love your videos!

Where I rent from in Southern California is probably the lowest cost around here (about 35 nm West of Flying Monkey) and the 1980's Cessna 172s with IFR GPS rent for $145/hr wet (which is pretty good). The last time I looked, everywhere else within about 50 miles was more, and a lot more in the direction of Los Angeles.
