I’m having trouble finding anyone who wants to handle this issue and the sale of the airplane is in escrow pending the resolution of the oil pressure issue.
Ask Paul: One and done

More on Lycoming’s XR-7755 engine
When Joy Hobbs sent in a photo of her grandfather and his co-workers by Lycoming’s XR-7755-3 engine, it attracted a lot of comments from General Aviation News readers. Our Lycoming expert gives us some more insight into the largest aircraft engine ever built.

The men who built the largest piston engine in the world
Question for Paul McBride, the General Aviation News engines expert: My grandfather, Russell Leuck, worked at Avco Lycoming Engines in 1943.

Would a synthetic oil be beneficial to my RV-7A’s engine?
I have an O-360 Mattituck (experimental) engine installed on my RV-7A. I have been using Aeroshell W100 Plus for more than 15 years.

Ask Paul: You can’t get there from here
I have read Lycoming Service Instruction 1304J and wondered if I can expect to find a Form 337 for an engine on the CD the FAA sent me with the aircraft records for a Cessna 172. The engine once had the following on the data tag: O-320-E2CC. I am told the engine was converted to an E2D per the logs.
Asking questions before you start an aircraft project will save you money
The Lycoming IO-540-AB1A5 has a rating of 230 hp at 2400 rpm. Can I just change the governor and increase the RPM to 2700 (like the D4A5) to get 260 hp or do more technical modifications need to be done?
