Will this cause my car to miss fire?

Yep, oil on the spark-plugs will cause misfire, but you can clean them with a wire brush and gasoline or some other solvent to get you through until payday. You may also want to check the "gap" on the plugs which could have been messed up when he took them out. While you're working with them, you should also take some time to make absolutely sure the electrical connections are snug.

Oh, disclaimer: Gasoline and other volatile cleaning solvents are flammable and release flammable vapors. Do not smoke while cleaning your spark-plugs or work in the vicinity of anything with open flame or that produces sparks.

So you are saying he removed the plugs before getting rid of the oil and the second the plug was removed the oil and grit that was in it went straight into the cylinders? The oil on the spark plug electrode can could be cleaned off BUT you have now baked it on by driving it so need new spark plugs. Hopefully that is all you need with all that dirty oil going down the bore.

You bet it'll misfire. Clean the boots and the plugs with brake cleaner to remove all traces of oil. Then squeeze a dollop of dielectric grease into the boot. Replace the plugs ASAP.

The first thing that should have been done is to repair the spark plug *well seals so oil will not leak down the threads.

You can clean plugs. If it didn't do it before the gasket repair. Its something along that line. Check plug wires and firing order also.

Shouldn't bother them.

Break cleaner should be your best friend.

Hi I have a 2006 Audi A6 Quattro with the 3.2 liter. My valve cover gaskets were leaking really really bad and there was a lot of oil inside of the spark plug holes. So I had my cousin change them for me and he said when he pulled the plugs that all the oil got all over the spark plug ends. He said it might make the car misfire and I should change the plugs. Well I don't have the money for them so I have to hold off until payday. Well my car idles ok but the second I start moving it starts to miss fire, and if I speed up really fast it still miss fires. So...

Since oil got on the spark plug ends (where the spark actually happens) will this cause them to miss fire now?
