Got it. Bored at work, I go check fluid levels. I've had a really bad oil smell lately. Open the hood and see a large oil streak down the valve cover. Streaks from middle to rear. The cover is cracked! I can feel with my finger nail. Plus the rear O2 exhaust cover has sludge over it again.
If I didn't have to replace the valve cover, I could get it done in about an hour. Now, I'll have to wait for a cover. Who has a good source?
