I gave a full tune up on my car back in March. ( Plugs, Wires, Filters, Oil, etc...) Well it was running great for a month or so and then it started chugging and puking. Well I later found the problem to just be a simple vaccum leak and replaced all the hoses. Ran great again for about another month and started all over again. Well I then found oil to be on the top of the three back spark plugs but not on the bottom half so I knew it wasn't a O-Ring so I replaced the Valve Cover Gaskets. Well I'm still getting oil on the plugs and have no idea why. I believe the chuggin is from a bad Mass airflow sensor or the EGR valve but I'm not sure. One is $90 and the other is $170 and non returnable. So I guess I will have to take a gamble with that. The oil on the plugs is confusing the hell out of me. I know its not the O-rings or the valve cover gaskets and oil doesn't flow through the intake gasket.
Does anyone have any suggestions on what the problem may be for both issues? Thanks
