    Well it could be a few things. Hows your oil pressure? Whats your exhaust looking like?

    Without more info I'll throw out that maybe your piston rings are worn out or completely shot.

    if it happend all of a sudden check #1 the turbo first may be on its way out (blown seal) #2 make sure no oil in the water (oil cooler) #3 then if those 2 are eliminated then it may be deeper like broken rings (hope not)

    pushed oil out blowby tube. figured it was combination of a few things heavy load 131000 lb.+ high winds, trying to maintain speed,20 degree weather temp. water temp. only got up to 175 deg. all day. once the outside temp got above 30 deg. and water temp. got above 185 it quit pushing oil. no tubo oil leak.

    If you coolant tempature is not getting up to a reasonable tempature. Then you need a winter front. To get the oil tempature to at least 200 degrees you may need a belly tarp, a canvas cover from the bottom of the rad to the middle of the transmission. These two things will increase your fuel economy, and stop the engine from blowing out the oil from the breather. Just a thought!
