Wayne, i would ask,does your engine have a hose returning crankcase gasses to your intake manifold ? i had one pulling in a lot of
oil on an old "y" block once. big problem with this whole scenario is a quart of
oil in 50 mi. would give you enough smoke to look like you are on fire ,foul out your plugs,and be running out your exhaust. are you sure your not loosing it on the hiway at speed with siphon/blowby or ?? merry x -mas karl
