oil in combustion chamber bad?
 
I purchased this engine from someone recently. It is supposed to be rebuilt with all new seals, and never ran. I told him I was going to come over and compression test it. I noticed he added a good amount of oil into the engine. I recently purchased a rotary engine rebuild video, and did searching and watched videos online. This will be my first 13b rebuild. I actually bought the engine to use the new seals and piece together another engine with the best of all my rotors, housings, irons, etc

I was going to change out the water seals anyways, but what do you think about the rubber oil seals on the rotor. I noticed a lot of places that sell engine rebuild kits also only sell the o ring kits separate. I wanted to purchase that, but I also noticed it does not come with the oil control rings.

You think the oil will damage the oil control rings?

If he added oil into the internals and it hasn't ran,that is a good thing.Prevents rust and moisture from setting up on the inside.
Did you compression test the engine,and if so what were the numbers like?

It was late at night, I brought my flywheel too. When I did the flywheel on, it jammed the key way, and he didn't have sufficient tools for me to reMove the key, and reposition it! I drove 2 hours one way to get it, and everything looked good, so I purchased it.
I read that cold engine compression numbers on a rotary are actually higher, true? I'm not sure what to expect on a rebuilt engine
