Long story short... Did compression test, all cylinders at 150lbs, no noticeable change when oil is squirted in cylinders. All plugs look good except #1 which is heavily oil fouled. Tried the easy 1st step and replaced the valve seals. No change... No nasties as far as oil/exhaust in coolant, no coolant in oil etc.. this is at 1500 rpm This is at 2200 rpm And a picture of the lovely cloud it leaves (neighbors aren't liking me too much) Cloud kind of lingers and hangs, has a greyish tint to it and doesn't appear to be coolant but oil smoke. (lingers too long to be coolant) ANY IDEAS????? I'm starting to think maybe a broken oil control ring or something.
