Craig "will wind up with an overhaul well before TBO"
You are stating that the overhaul had been done some 20 years ago. That is almost twice the time of what Continental recommends for an overhaul. After all, not that bad.

Took some good suggestions on this forum and went to straight 100w oil. That brought the pressure up about 5lbs. Was still below 30lbs, so replaced the pressure guage with a new and and came up another couple lbs. Finally had the accessory case removed and took the oil pump in to an engine re-builder and had the pump overhauled. Was told that the bushings were in need of replacement and the cover was a bit warped. Brought it up another couple of lbs. Supposedly a common problem in the C65-90hp Continentals and either would cause a loss of some pressure as the oil warmed. So, now the engine runs in the lower end of the green, but I'm there! The temp stays at about 100deg about the ambient temp, so that is good. Even though the engine only has 360SMOH, it was done 20 years ago so I suspect that could have been a problem. Anyway, I now plan to change oil every 25hrs, send a sample in for metals check, and of course, keep an eye on the oil temp and pressure as always,,,, Suggestion, if you are buying a coupe, make sure you get the aircraft flying for about 30 minutes. My engine started and ran-up with great pressure and then would only gradually drop pressure after 20 minutes of flying. Didn't even show up at the annual. Now I have close to 2K in repairs and probably will wind up with an overhaul well before TBO.... Don't you just love airplanes! :^) Craig Peterson N87018 #191 ----- Original Message ---- From: cpetemn <[EMAIL PROTECTED]> To: [email protected] Sent: Monday, June 23, 2008 3:34:09 PM Subject: [ercoupe-tech] oil pressure As I've flown my C-85 coupe more these hot days, I have noted that when I first start the engine, oil pressure is in the 30-40 lb range. Then after I am at cruise, it runs at about 21 lbs or in the middle of the caution range. I asked my a&p and he thinks it probably has to do with the multi-vis oil warming up and the ranges were set long before multi-viscosity was available. He also has another customer with a C-75 coupe that runs in the same range. So what oil pressure does your coupe sit at when cruising? Craig Peterson N87018 #191 btw, solved the brake problem where the pedal needed adjustment and was binding a bit.
