oil and smoke frome pcv valve

Postby lineguy » Thu Feb 13, 2014 11:57 am

i'm new to the forum and new to tractor ownership, so if i sound if i have a rather large "duh" factor,it's because i do! a friend and i went in together to buy a 1610d yanmar,whitch ran really well untill i started it last nite.it fired up ok but almost immediatly started blowwing large amounts of smoke and a little oil out of the pcv valve hose .i shut it down right away.i hope whatever is wrong isn't serius ,but i have a gut feeling i'm looking at something major.any ideas of what the cause is?

A diesel engine will always have some smoke/oil/pressure coming out of that hose. Even many brand new diesel engines. It is hard to describe how much is "normal" but, typically, as long as it starts easy I would not worry about it. The pressure is just compression that has bled by the rings and if you still have enough compression to start easily I would not worry about it too much. There should be a little oil baffle (sometimes looks like a ball of steel wool) in the fitting where the tube connects to the valve cover. That should keep the oil from blowing out.

Now, if there is a LOT of oil & smoke or other symptoms of something going wrong then there may be a bigger problem.

thanks for the reply.ithink i have a larger problem, as there is an abnormally large volume of smoke at high presure coming out of the breather tube that is routed down the side of the motor.

Have you checked the oil? How much?

Good dipstick seal. If all good, it's overhaul time.

Hi forum (newb), bump. So where did you end up. I purchased a YM220 dirt cheap and have same thing. However the engine sound good and runs fine.

I'm replacing clutch next weekend and adjusting values. See where I end up.

If oil is black, change it, and try running a carbon cleaner,such as POWER SERVICE in your fuel tank.
