Fully understand "should" & "shouldn't". When I did the vtcs removal, whenever that was, the intake manifold had some gold color to it around where the pcv hoses hook into it. There's filmy stuff inside the hose going back from vc to intake. I go thru 1/4 qrt of oil, every 2 weeks which is about 600 miles or so at 75-80mph on frwy. Just recently switched to castrol hi mileage 10-30 from syntech 0-30 german stuff with no difference in consumption. My car doesn't leak, doesn't smoke at startup or at all, pcv is clean & functional. None of the plugs look crazy & the tips are ashy color just like they should be. Compression is all good accross the cylinders. What does that leave?
