    New YX140 leacking oil out of bottom end breather hose

    Could this be due to over heating even tho the engine was only run for 2hrs max before leaving it to the next day ? Iv have other people tell me that the rings could be on the wrong way or something like that. I haven't had the engine apart infront of me yet. So I'm unsure and never had this problem

    New YX140 leacking oil out of bottom end breather hose

    Around 800ml, it's what was recommended from the supplier. Engine was been used without an oil cooler as temps aren't too hot here

    New YX140 leacking oil out of bottom end breather hose

    Just brought a brand new yx 140 eitha z40 race cam in it and it shoots all the oil out of the bottom end breather hose. Is this normal? It emptys itself within 20 minutes.
