I think we will just agree to disagree. I am not a fan of reusing rings in any circumstances, I am 98% not a fan of reusing a piston, and I am 90% not a fan of doing a rehone. Your opinion clearly differs, you do you and I will do me. Fly safe.

Recommend @Parker_Woodruff he is good at advising all the pluses and minuses.

They rotate in a path based on wear patterns. It is not a smooth surface after break in. When you reinstall used rings both the rings, cylinder, and the pistons will make metal again to find their place. They will continue to do some of that over the initial break in which is why at some point they all fail.

What is the prop make/model # on your prop logbook.

What does that remotely have to do with replacing or reusing rings.

Certainly the barrels do a lot more interesting things on an individual air cooled cylinder.

None because I never done it, but I have certainly done it on a lot of cars. The cylinder doesn’t stay round when it gets hot. The rings when new wear down and seat into the pistons and to the nature of the barrel. You will never get them back in the same place. Folks are always free to do what they want but for me I wouldn’t reuse a set of rings. Depending on the piston I might reuse it but for the most part if the cylinder is coming apart it is because the rings or piston have issues, if one ring is bad why reuse 2 others that are probably going to be equally bad or getting ready to be bad. My 2 cents.

Breaking in new cylinders involves seating the rings. Once those rings are set and you pull the piston apart you are never going to get the rings set back in exactly the same space. They are either going to need to wear back into their new position or if they and the barrel are worn too much in that alignment spot they will leak a bit (or a lot). They also need to seat into the landing on the piston which is why most will say change the piston and rings together. Depending on things the old ring/pistons may work again, they may not, or they may work for awhile. They definitely will know they were apart though. My advice to all is if you pull a cylinder and decompress the rings, new rings at minimum and preferably new rings/piston/hone.

I can tell you are not a pilot. There are many fake speeds in flying which is why true airspeed is called true, not liar airspeed. True is all that matters because the other speeds are fake. If you increase your true airspeed then you go faster. Look at my TAS indicator and you will know why I fly an executive.

If you cut the back off it will make a ram air and add at least 10kts of TAS, this is the real trick.

The key is once it and the airplane are clean to wax it. I like Jescar Powerlock. Then ensure you maintain. It is awful the first year but thereafter easy regular maintenance and a once in the spring refresh on the Jescar.

The only difference between IRAN and Major is selling price. A 20,000hr since major engine that is consistently flown, IRAN, etc. is just as mechanically sound as an engine that has been overhauled 100hrs ago (removing infant mortality). One is going to command a much higher resale value.

I have a set of rhino ramps similar to what is pictured to work on my 71 MGB. I also have everything else (fridge, chest freezer, seating, $2.6M in tools, and now a Starlink) minus the built in office shown earlier. Hangers are the ultimate man cave and money sink. I probably spend more on the hanger than the plane….

Don Maxwell bought the STC from Jose Monroy. My understanding is they have a DER approval in place to get around FAA/PMA. The FAA though has not yet processed the STC transfer. I am on the list for the tanks but as of this writing no news yet.

Personally if you got the cash a new probe and line would be the way to go into the 700. If you don’t have the $$ your situation sounds like a bad wire not the probe so would run new wires and see what happens.

I only do that with gas caps

Cell service sucks in the area and it also isn’t super fast. This frees me up to do things like download database updates at hanger, do work in hanger (AT&T will not allow my work VPN to function), and you can switch to mobility for a month for only $30 (take it anywhere so say Osh Kosh, camping, whatever). It’s $120 a month which isn’t cheap but not bad either. Mostly though I just wanted it so I got it :-)

You can’t get them repositioned where they were so they will have to wear to reseat again. In a pinch rebuilding a beater car engine for expediency I have reused rings, but I would never reuse for anything I valued. All reusing them does is assure you in the near future you will have a problem. Certainly we can make arguments around infant mortality and a bunch of other things. Personally though reusing rings is a no go for me.

Finally got my ancient garbage borescope working. Puddle of oil, taking it out to Cole to get pulled. I hate airplanes.

I fly an Executive. My panel is elephant hide filled with sperm whale blubber, you could drop a lead weight from 100’ and it would graciously absorb it and supplely caress it.

You are free to do so, best wishes.

When you have been in a relationship for a long time synthetic vision helps.

The key is to sneak into the TFR right at launch. If you are really lucky you might get to see some flares in addition to the rocket. Quite the light show.

This is the correct answer. You are probably better off with only a lap belt if you don’t have head rests. It is a restraint system of lap, shoulder, and head rest.
