After talking to the AP, I’ve decided to not fly the plane until I go for annual - not due to airworthiness, but to keep from making more metal. It’s hard not to fly but for the overall health of the engine, better to not over do it. For Annual, IFR certs, step actuator, new cylinder, quick drain is planned. After annual, I’ll see about the auto pilot - that is still planned but want to make sure the engine is sound. -Don

Hum.. go around would have been in order if that is the case… VFR in the video… -Don

Oil pressure, fuel pressure, suction in the green but, oil temps were around 100°. I’d suspect engine not running but windmilling based on that. RPMs around 1500… Taxiway looked clear and grass available. Why ruin someone else’s day. Plenty of options to not hit the plane on the runway… Why would you post this anyway on the internet? FAA will have his a** now… -Don

Blackstone report pretty much shows what we thought. I’m waiting on the new cylinder and will replace this one completely. I’ll see if it can be overhauled since it is a first run cylinder. While the totals are not crazy high, the trends clearly show rising metal counts. With borescope, filter and oil trend analysis, pretty much calls it… 3/30, 8/28, and 11/14 all show rising numbers. 1/15 was before the cylinder IRAN… -Don

Ordered a new Cylinder kit and piston pin/plug: Superior SL36006W-A20P - O-360-A1D Superior Sl13444-1 Piston Pin/Plugs from Airparts Inc. Looks like they'll have them estimated on 12/20/24. Lycoming kits are backordered still but not sure if they'll have it sooner so figured I'd get this since annual is next month. Sent pics to AP and he agreed something is amiss with this cylinder. I'll see if this is still overhaulable but for now -- going new cylinder... -Don

New actuator coming for the step - power is getting to it - very odd where it stopped. Will be interesting to find out why this one failed… -Don

I'm waiting on the revised STC for my 66. I should know more next month... -Don

#4 Cylinder -- Bore -Scoped Sending to the AP -- flew her today after doing this -- she is running strong, no oil burning/leaks -- kinda disappointing but this cylinder does not look healthy to me. Looking to see if I can get a new one...

Spoke with the A&P (sent him the pics) this morning, he agrees, looks like the nitride cylinder flaking. He also said do the SI, change the filter in 5 to 10 hours, for me to borescope #4, and let him know what the Blackstone report says.. That is the plan for now. Lycoming’s SI it really clear on what to do, thankfully… https://www.lycoming.com/sites/default/files/attachments/Piston%20Pin%20Plug%20Wear%20Inspection.pdf -Don

That is going to be checked at annual next month. I went from nothing to this since the cylinder was done. My IRON was higher on the oil reports after the cylinder but trending down after each oil change - waiting on the latest to see if it went up. Borescope will be done. Annual is after the first of the year. -Don

Got a couple of approaches in today -- oil is doing fine -- but, the filter, for the first time, is showing ferrous metal after the cylinder IRAN. The past oil reports showed it going down -- I have about 60 hrs on the engine since then. I'm going to keep and eye on it and do the oil changes per Lycoming SI 1492D. Pic of what I found after running a magnet over the media (that is a small magnet too):

Flew today with my CFII, 3 approaches, 2 holds, plane flew great, oil leaks in check. Noticed how much the step slows down the plane. Next on the list now that oil leak is better. takair gave me some tips so I’ll check those out. Discovered the tight fittings on the sump is not unusual if not removed in a long time. I’ll ask about them at annual. Running great. KGGG has a lot of construction going on so I’ll call Maxwells and ck ahead of time about the control rods before venturing out there. -Don

Lycoming morning sickness — may need the exhaust valve guide reamed… Lycoming may have an SB on that… https://www.aopa.org/news-and-media/all-news/2022/july/12/aircraft-maintenance-reaming-lapping-other-valve-tasks#:~:text=If the valve stem is,as Lycoming “morning sickness.” found it… https://www.lycoming.com/sites/default/files/attachments/Procedure%20to%20Determine%20Exhaust%20Value%20and%20Guide%20Condition.pdf -Don

I asked twice, so, hope they see those… never heard anything back though… -Don

When ya gotta, ya gotta! Nice… -Don

BTDT.. don't think they’re interested but couldn’t hurt to contact Trio… -Don

Yeah, will ask AP about it at annual…

Well, started on oil change, found the quick drain won’t go up anymore. Tried to remove it and someone in the past seal those drain plugs forever. I tried removing the plug on the pilots side and BROKE my cheap wrench! So, had to resort to using the electric oil drain pump and that did the job. I’m not about to drop the sump - I have a feeling the sump would need to be replace since these damn things are in there for good. Not spending 3k to 4k on a new one — didn’t find a used one either. Electric oil drain pump worked just fine and a drip of oil occasionally from the quick drain. Would love to know who seal the drains shut… Anyway, change is done, filter on, run up with no leaks. Didn’t see the problem yet on the step - looked for the fuse but didn’t see one. May have to have the shop look at that during annual. -Don

Jack points maybe? — may have something they inset into… -Don

Looks like the oil leak is solved, did a flight today and the residual oil is pretty much gone. Doing oil change now to clear out the dye. Noticed my electric step stopped going up/down though - it’s attached to the beacon and that is still working. Sent a note to @takair about it. Will report back on it. Gonna give Maxwells a call on the control rods to see about changing those out. Never ending maintenance it seems… -Don

Icarus but not cheap — great trainer - simulates IFR pretty well… https://www.icarusdevices.com/ -Don

Everything has gone great -- did some IFR approaches with low ceilings (400 ft). While doing some lubing, I realized the rudder and elevator controls need some love. I ordered some low time control rods from a 66 Mooney that look like new! My current ones look like this (below) so I think its time to have them updated. I'll see if Maxwell's have time -- wouldn't think it would take too long. I also purchases the dual elevator rods that are in the tail section. I'll have them replace the rudder heims and that should really get this in great shape.

He detailed his journey here on Mooneyspace - from when he found it… -Don

Mine has 2 ‘longerons’ if you will and the transponder antenna… -Don

W91 - Smith Mountain? I believe they too rent hangers… -Don
