WaynePierce Posted October 25, 2022 Report Posted October 25, 2022 Plane is in Annual since yesterday, my A&P helped me find a leak that has been plaguing me. It seems to be leaking in front of the oil filter. It is not the oil filter or the are where the oil filter seals against the engine. Have any of you experienced this? My guy says he's never seen one leaking from there, have you? And if you have is it fixable without pulling the (I forget what the technical name of this part of the engine) gear housing?
PT20J Posted October 26, 2022 Report Posted October 26, 2022 The IO-360–A3B6D has an adapter for the spin on filter that has a rubber gasket attached. The adapter is attached to the accessory case by the threaded nipple that the filter screws onto. Sometimes the filter sticks to the adapter and causes it to loosen. You should remove the adapter and check that the gasket isn’t damaged. Skip 3

Guest Posted October 26, 2022 Report Posted October 26, 2022 AD 2002-12-07 pertains to the oil filter plate gasket, assuming the OP has a D series engine
WaynePierce Posted October 26, 2022 Author Report Posted October 26, 2022 Thank you Clarence, I do indeed have the -D series and looking through the Engine Log books I have at home in a moment... I've checked the Engine Log books 1 and 2, and no mention of this AD. I see AD 2002 26-01 has been inspected along with "All AD's researched and found to be up to date" noted. But nothing on AD 2002-12-07. Now it might be in my ADLOG book that is with the plane at annual, the last entry I have is dated 3/28/08. Newbie question... How does one look up an AD? I tried Googling it and nothing returned then I looked at the "Dynamic Regulatory System" and still cant find this AD. I'd like to read it.

There's a related Lycoming service bulletin (543A) dated August 30, 2000. If your engine was assembled/overhauled after that then there shouldn't have been any AD action needed. 1
dzeleski Posted October 26, 2022 Report Posted October 26, 2022 My engine had this AD marked as complied with and the gasket recently failed, I had oil spraying everywhere. So obviously make sure the AD is done and the correct part number is used for the gasket but it can fail from age in either case. 2
PT20J Posted October 26, 2022 Report Posted October 26, 2022 I didn't know about the AD because it came out long after I had sold my 1978 J. But I remember replacing that gasket twice. Sounds like even after complying with the AD it would be good to inspect carefully at each oil change and keep a couple of spare gaskets on hand. Skip 2

Nothing is certain in these engines.

The ADLOG started fairly soon after this AD would have been noted. I'll be curious to see if it was included in the AD's the ADLOG company supplied with the folders.

Older thread here but commenting for continuity: Today I discovered an oil leak that appears to be from the oil filter adapter plate gasket mentioned in this thread; engine is a 2009 factory remanufactured IO-360-A3B6D so the AD didn't apply. Ordered a replacement gasket from Spruce ($80) and a tube of the 3M gasket adhesive called for in the Lycoming Service Instruction 1453. The SI directions and the adhesive data sheet seem to provide sufficient technical data for replacement of the gasket but thought I'd ask for any other recommendations from those who have replaced the gasket in the past. I plan to remove and clean the adapter plate tomorrow and should get replacement items on Friday. Thanks!

I had to grind the end of the socket so it had a sharp edge. 1
CCAS Posted January 19 Report Posted January 19 In case it helps anyone in the future, once removed, I found the gasket was adhering to only about half of the mounting surface of the plate. After removing the old gasket I found there was almost no adhesive applied between the gasket and plate. Also the torque on the nut seemed very low. I tried to add an iPhone video but the file type doesn’t seem to work Of note, I went back through my engine logbook and found that the gasket was replaced not that long ago (2022) by what I thought was a reputable MSC in the Midwest.
Gee Bee Aeroproducts Posted January 19 Report Posted January 19 What's material of gasket Part number good luck
N201MKTurbo Posted January 19 Report Posted January 19 The AD listed above references a SB that has a very specific procedure for gluing on the gasket. If done according to the SB it is very unlikely to fail. https://www.lycoming.com/sites/default/files/attachments/Procedure%20to%20Replace%20Oil%20Filter%20Converter%20Plate%20Gasket.pdf

skykrawler Posted January 19 Report Posted January 19 Gasket 06B23072 https://www.aviationpartsinc.com/ $74.39 Aircraft Spruce $82.75 Lasar $103.20 out of stock Who's gouging?

The SB/SI also reference the application instructions for the 3M adhesive #847 which are pretty detailed. Once the adhesive cured, the gasket and plate made a solid bond. 1
