I see that Jody seals up the crankcase halfs when reassembling, I presume the factory doesn't do this.
You must be kidding, if a sealing compound wasn't used every one would be blowing bubbles all over out of the mating surface, not to mention non of them would run worth a crap from all the lost crankcase pressure.
No I was not kidding, since I have not had the need to tear down my engine yet, I didn't know what was there, if anything. Sounds to me like some poor or uneven surface finishes if they would leak that bad with nothing.
So at the best they do use a sealant of some kind, but from the sounds of it either not enough or something that won't hold up.
