The O-200 oil pump usually won't prime turning on the starter and takes nearly forever to prime at an idle. You can idle the engine right up to damaging the bearings and still may not get oil pressure. If you want to pre-oil the engine, the technique Mike describes works pretty well, and is a really good thing to do if you don't know how the engine was lubed when it was assembled. If I have had the engine apart and lost the prime on the oil pump, just a few seconds at 1500 rpm is enough for it to pick up it's prime again.
When assembling any aircraft engine, I use a generous amount of Lubriplate Assembly Lube on all bearing, seal, and contact surfaces. The exception is the cam lobes and cam followers, which get a coating of black moly cam break-in grease on the contact faces. The Lubriplate grease will stay in place if the engine gets stored for a few years, and will protect the bearings and surfaces during startup until the oil pump primes and starts providing oil pressure. The oil cooler mount is where the after market spin on oil filter mounts to the engine on the back left side of the case. If you have neither, there is a small bypass plate mounted there on 3 studs. ?

I finally pulled the side plate where the filter mounts and poured oil in the top hole until it would not take any more. I think that I even turned the prop backwards to make sure that it would enter the pump. I then put the plate back on. This worked, I had oil pressure. PS, It takes a lot of oil, you have to back fill the screen cavity. Mike Sylvester kr2s builder Birmingham,AL.
