Use Picco, IDM or Sirio plugs. Use whatever number you need. (usually number 6 or 7)

P6TH plug which is the coldest you want to use on a JL .12, the PICCO P7TC is for a .21 engine.

The engines we use seal the bearing by liquid lock. If you want a big term for it "surface tension" (The a property of the surface of a liquid that causes it to behave as an elastic sheet). The tollerance between the crank and the case is critical to this working which is why loosing a bearing can make a engine non rebuildable. It is common for boat and some plane engines to not even have a seal at all. Our engines have a seal to keep dirt out of the bearing not seal vacuum. If you use after run oil or leave fuel in the crank case it will leak out the bearing over time. If the engine runs fine I wouldn't loose any sleep over it.

That is correct I was waiting for the teacher to spill the beans. But I guess he was waiting. All the statement was so that it was not needed to spell out that the lubricant in this case is spun into a liquid seal by the rotation of the inner raceway and balls at high rpm. I really do not think that there are many people who care about how it sealed. But I guess the teacher had to blind people with science for them to understand that if the front bearing is smooth do not worry about the leaking oil out as I stated in the posts prior. Thanks for the science of it I was not going to post the info. A++++
