I am not sure if they offer classes for free to anyone over 60 but one of the best A&P schools around is at Tarrant County College. They hold the actual classes out at Alliance Airport. The day course is 2 years and the night course is 3 years. They also have add on courses to specialize in avionics or composites, etc... I was enrolled and started but I could not make it work. My office is in Southwest Fort Worth. The evening classes started around 4 pm. They have a very strict no absence, no tardiness policy and there was no way I could guarantee making it to class on time every day coming from work at that time with traffic so I was not able to do it. But it is an excellent program. Tons of different aircraft and engines, etc... that you do hands on work on.

You just vaulted back to numero uno!!!

You are in a tie with @EricJ who posted one earlier in this thread.

@OSUAV8TER^^^^^^

AircraftSpruce.com sells one of these. I have not used it because it is damn pricey for a glorified box cutter with an attachment to it but they are available. Tempest AA471 Oil Filter Media Cutter | Aircraft Spruce

I have a 63 C model with an O-360-A1D. What is the lubricant of choice for the slip joint between the exhaust down tube and the rest of the exhaust? I have heard people use mouse milk but McFarlane makes their DAM exhaust lube as well. Is there a preferred lube for this? Thank you.

I am replacing it with a new cylinder.

@Centeno You may try here. 200HP INTAKE DUCT M20 E&F - 600115-005 — LASAR They say they have it but it may not be in stock but they may be able to help you get one.

You can buy seat belt extenders on Amazon and other sites. It just depends on the type of attachments you have. There are different types. I have one from a company that was called Free The Flyer but they are apparently no longer in business. I couldn't find them online.

When I took the cylinder back, the shop did a quick measurement and as I said earlier, the bore was at its maximum limit. They called me later after actually doing close inspection and the bore was also out of round.

What was missed is the fact that the number one cylinder was pooled with oil and both upper and lower spark plugs were wet. I showed photos earlier.

That’s what I would have suspected but he didn’t say. I should have asked but I was just kind of happy to possibly find a solutIon. I’ll ask. Though my EDM 900 never showed any issues of overheating or any other problems.

An update on my cylinder. I dropped it off at the overhaul shop this morning. It is nice that they are only an hour away by car and I saved the shipping. Anywho, while I was there the mechanic measured the cylinder bore and it was at its limits. Also the rings were bad. Visually they were okay. But he took one and twisted it expecting it to break and it never did. Just kept twisting on itself. I was told that they eventually should snap but mine never did. So, they are going to have a cylinder ready for me next week. Hopefully I can put this to rest and get back in the air just in time for my annual in January.

I don't know if this helps you at all, but this is my panel in my 63 C model with a 530W, GNC355 and GFC500 all in the same column and has a small amount of wiggle room at the top. It may give you an idea of the dimensions you need to do what you want.

@Echo See above ^^^^^^^^

I cannot make out any cross hatching. I would have to check the logs to get you info on time in service, etc…. I can check tomorrow.

So, I was able to get with my mechanic. We tried the ring flush and it seemed to pass by the piston and into the sump normally. So we elected to pull the cylinder. All rings including the oil control ring were fine. Nothing broken. The piston had an interesting mark which you can see in the photo. The whole top of the piston was black with carbon except for this one spot that you see in the photo. I have also attached a photo of the cylinder bore. I have more if needed. So we are sending the cylinder off for overhaul and we will see.

The cylinder just had the exhaust valve replaced. I wonder if something went wrong there.

Compression on that cylinder is 68/80 cold so I suspect it would be much better when hot. All other things are in the normal range including CHT's, EGT's etc...

Thanks. I misunderstood. Thanks for the clarification.

Thanks to everyone who have responded. I appreciate all of the advice.

Thanks. I believe this is what I will try this weekend then go from there.

The airplane is not in annual. It is just their advice to not fly it.

I do have some of that in my hangar. By the way, a conundrum, if I try the ring flush and it sounds like the flush is going into the sump then the instructions say the ring is clear but how do I still know that it is not a broken oil control ring letting the solvent go by? I was told not to fly it so I can't tell if the oil burn issue is resolved either.

Oil analysis is done every oil change and I have attached the most recent report done right before the offending flight. I usually fly over 100 hours a year however the plane has been down multiple times for avionics, autopilot, etc... But it normally flies about 100-150 hours per year. It is definitely not a hangar queen. The current engine is about 1400 hours since overhaul but it has had cylinder work done on it over the last 4-5 years. This particular cylinder was off at the annual (January) for an IRAN and exhaust valve replacement. There was nothing mentioned about any other issues. The increase in oil consumption started last year and was using about 1 quart every 4 hours or so compared to 1 quart every 12-14 hours previously. This was within Lycoming specs so I was not concerned and just monitored it. However, it made rapid leap on one 3 hour cross country. I was about 5 minutes from landing and the oil pressure went from 64 or so which it usually runs down into the upper 50's. The EDM 900 alarmed me. I made the landing at my destination and had to add 4 quarts of oil to bring it up to 7 on the stick. I flew home and actually the oil burn was better. I made it back with 5 quarts and I have not flown it since from the advice of the A&P's. N6541U-230608.pdf
