Just purchased an 82 300D turbo. I changed the oil and drove it for 60 miles on the highway checked the oil level, added 1/2 a quart and drove home. three miles from home the oil pressure began to plummet. I stopped and looked under the hood, oil on the hood above the not completely seated dip stick and lots of oil all over drivers side of the engine. took four quarts to get back me back on the dipstick and home. Today I hooked a hose to the dipstick tube and over to a plastic container and sure enough in 20 minutes the car pumped 1/2 a quart of oil into the container! Is there a breather that could be clogged or have I just get excessive blow by? fyi I tried the same hose on the breather nipple on the valve cover and got some oily residue in 1/2 an hour of driving but no liquid oil. Any thoughts?
