Ok. I made it to the track. Car run a 12.77. @106 I was happy. But... I'm smoking out of the passenger side and #4 plug has oil on it. Before i get new heads. What's wrong? With the valve cover off and engine running. You can hear like a valve not closing all the way like a piston moving up and down And oil steam come out with the (valve cover off of course). Runs fine. Just smokes. I know it's a lot to ask. But I need help. Is it a bad valve or rings? It just sounds funny with the cover off. Thanks
