A little background, my truck has never dripped oil out of the breather tube, this morning I had to fight 14 inches of snow in 4wheel drive to get to work, 4.1 miles. Never got over 15 mph, the engine never warmed up as well. When I got to work I parked it inside on concrete and noticed that it had oil under it where it had dripped out of the blowby tube. When checking the oil, on the side of the dipstick that faces up it showes about 2 inches above the full line, but when you turn it over to the side that faces down, it shows in the safe level. I've pulled the stick and wiped it down, when I insert it back in for 5-10 seconds and pull it out I get the same results, the side of the dipstick that faces up reads higher than the side that's down. What gives? I guess it could be dripping because I drove so slow that it didn't blow it away driving down the road, no oil on the underside of the truck.
