You said "parallel valve". In a future video, can you show the difference between engine designs - different valve designs, etc. Thanks so much for this video, Subscribed!
Thanks for your video. It would be appreciated if you would answer the posters questions below. Here are questions from me which I hope you will answer. If a steel barrel is good and the aluminum head is cracked, do you demate the cyl barrel and mate it to a new or good head-? If you do not demate cylinders and heads, why do you not do this-? Before removing exhaust guides do you heat the aluminum head to a specified temperature to remove the guide and press in a new guide at this spec. temp-?
One more question , Chrome Cylinder after you honor the cylinder to remove the glasse and make it wall patten do you continue or reinstall New chrome piston Ring thanks
To the previous question ,,do you continuous as a chrome cylinder ,, then to use Piston Ring for a Chrome cylinder,,which you know it can No be chrome ring
I have read that in the past, a solution was used to wash aircraft parts in, before overhaul or renovation. This solution would remove paint, soot and grease from aluminum without damaging the underlying metal. What was the name of this solution? Is it (or similar) available nowadays?
I worked for Flight School down in the lower 40 I was wondering where are the go no go is on whether or not a cylinder is repairable I have about 20 cylinders and none of them were mothballs so some of them have gotten rust in them some don’t look that great some don’t look that bad. What can I do to save myself from sending cylinders that are not fixable.
A video showing all the things you're explaining about these overhaul processes would be welcome by all I'm sure .
Absolutely. I wanted a blow by blow demo of all the steps.
I did cylinder overhaul/repair at Mattituck Aviation for 5 years. This brings back memories.
How did you like doing that kind of work?
Steel cylinders, or alloy with Steel liners , or alloy with Nikasil or Equilivent coatings.
Very good and informative Video, only thing to improve is the sound, but keep your great work ;)
Excellent presentation
Thank you!!

Your refurbished cylinder is so beautiful it makes me want to cry 😢😭
What’s going on with the restoration on that Cessna?, hope you guys still have move videos 👍
surprised no one asked what the average cost difference is between repaired and overhauled if the cylinders are sent to you.
Thanks for your video.

Great video, please use mic. Great process.
Talk is good - pictures are better !
What type of material are the intake & exhaust valves made of? Do the turbocharged engines require different valve materials?
Thank for this explanation ,my question is for the exhaust valve for o 360 exhaust valve 1/2 stem where I can find a Chuck to hold the 1/2 valve
Thanks for watching!
What do you mean by this? A chuck for what purpose?
A Chuck for 1/2 valve or exhaust valve my valve cutting Machine Up to take 3/8 Valve stem
Hi she's flying a 1985 piper pa28 161. Why not flay a new piper pa 28?
What ring materials and thickness to modern aircraft engines use?
Good afternoon, how are you? can you give me tips on tools for removing the studs and also tool for grinding rocker pin bushings?
One more question , Chrome Cylinder after you honor the cylinder to remove the glasse and make it wall patten do you continue or reinstall New chrome piston Ring thanks
Good questions! We always want to install NEW rings after honing the bore and breaking the glaze on the cylinder wall.

MEK ~ Methyl Ether Keytone (AKA Aircraft Stripper). Maybe?
Have you ever seen a cylinder installed without an O-ring on the base?
How do you bore with a choke? What machine and tools are used?
Check out my comment on the cylinder honing video I explained how honing vs boring a choked cylinder
How can you measure cyl HD location were the valve will be installed valve guide seat
What do you think about Lycon jugs?
2 question ,were can I get the exhaust flange cutting tool , and were can I purchase cyl stud installation tool
Can you explain how you check valve clearance on a 0320 straight valve?
Is Laser Cleaning approved by either OEM?
Now, I am confused on hone angles.
Moly rings VS. Iron...
Is there anything to that?
Thanks,
Mark
Thanks alaks
I go your work shop take me
Does any company make aluminium cylinders with press in liners and press in valve guides? If so how much weight do they save plus better cooling.
Excellent presentation, Could you repair the cylinder(05K21104) we have?
I know I am late to the party but…if you over bore a cylinder and put in higher compression piston, can we give my 200HP Arrow more power? (Lycoming)
Not legal
Get an experimental?
Bore/Stroke wont add much power, maybe ~ 3%
Higher compression pistons gives 3 ~ 5%
Do you guys buy as removed engines? Lycoming io240, low time out of a liberty.
Occasionally, but sorry not interested in that specific engine. List it for sale all over the web, it’s a good time to sell 👍🏻
What is the name of the rod cover spring compressor? Where can I get one?
I worked at an automotive machine shop and we did 3 angle valve jobs. Is that ever done with aviation cylinders?
7 angle
Great video, bad sound
Why are aircraft cylinders the only cylinders on earth built with a choke? The heat and expansion theory doesn’t seem to fit on the Harley or VW
I think you ment the valve seat angle is 30 degrees and 45 degrees respectivly ?
Es posible explicarlo en Español gracias

I used to nickle plate aircraft cylinders in Tulsa
