i wonder why they carry the part then

Quality / Viscosity and Oil change interval issues most likely. Crankcase contains moisture and when mixed with motor oil that has been run past its useful life (mileage or TIME INTERVAL) it forms acidic poison that eats away valve seals/bearings/cams and seizes the oil seal piston rings in place. Your engine is gunked up man.

If you drive all city, I'd do an oil change and do some highway/interstate driving. Change it and do it again. Sounds bummed up like mentioned above.

Same reason they show an inline fuel filter for the 2005 "T" code engine, when in fact there is no inline filter on it. It's called an ERROR. Not every part they show for a particular vehicle applies to said vehicle

. I drive it 50 miles day to work. Mostly highway Just changed oil few weeks back 1200 miles ago. I use 5w30 Mobil 1 full synthetic extended performance. 7500 miles between changes. It seems to getting worse now few times a week now it does it. Very big cloud. I have to laugh when I see it go by the window lol.

Cleaned the valve cover and it has been a week and not had any smoke.
