Hey Guys re leaky bearing, i had a client bring one in with that. I noticed a little weaping of oil, i checked the seal , best way to do it is to try to turn the seal with your thumb nail.. if it turns its time for a new one OR you can seal the outer edge with 262 loctite ( thats a bodge way to do it ) its a quick fix at the track really than a long term thing. Anyway i tested the engine in my buggy for 2 tanks and it ran fine . no front bearing is air tight , they all leak to varying degrees. So dont stress if you notice this happening. if the engine runs reliably then its not doing any harm.
Cheers MM
