Mine does the same thing. If I remove the oil fill cap when it's running, I get spurts of oil on the underside of the hood and on the windshield. I also reported a ways back when attempting to pour Seafoam into the oil fill, it just got blown back out of the funnel...think I'll try pouring it down the dipstick tube next time. PCV was clean and working and power is good. I think it is just inherent...any others?
