oil tank breather

[diabolics]

Hi, the oil tank on my K2 has a small breather pipe on the top under the seat. It looks that there should be a pipe attatched to it. The previous owner had blocked it off with a small piece of pipe and a bolt this I knew was wrong. There is no mention of it in the Haynes manual that I can find. Should the breather pipe from the top of the engine connect to it. Oil comes out of the tank breather under load. Any helo appreciated.  Thanks Adrian

no the top pipe should hang down just like the engine breather,and the lower smaller pipe goes to the back of the gearbox

Me again,could anyone send me a pic of where these breather pipes should go. Previous owner had a little play around I think and they don't exist in the Haynes manual. Thanks again Adrian

It looks like it was an issue for the previous owner too, if it was blocked off. Engines usually chuck oil out of breathers when there is pressure in the crankcase / rocker cover. That could be blowby from worn pistons or rings, or other causes, you may have to consider pulling the engine and have a look in there.
