Default Re: Drinking Problem

Remove the spark plugs and look at the tops of the pistons, turn the crank for the best view. Sure, head off would be better, but hold off for now. Do the compression test wet and dry. Most would have done so before posting. Small amounts of oil consumption by way of rings will leave a black crusty residue on the tops, the more oil that passes the rings, the wetter the (shiny) it is. When the oil gets out of control Believe it or not it will wash the top clean that's when plugs foul. Also don't rule out rear main when driving - look and measure crank end play.
