Have a question last night running a z28 mid second gear heard a really weird noise under the hood. i have a supercharged gt just so you guys know, well it started to smoke about a mile down the road and got home and checking it out the was oil on the passenger side valve cover i checked the pcv valve and it was filled with oil so i cleaned that out and tried to clean it the best i can. i checked the valve cover bolts they were all tight. does anyone have any idea where the oil could be coming from. I have no loss in power and full oil pressure. THanks for the help
