You have oil in the spark plug holes. This is due to failure of the valve cover gasket o rings that seal the holes. a valve cover gasket set will take care of that problem.
When oil gets in the holes, that causes the spark from the coils to arch. This will cause your vehicle to run rich and stutter.
You should replace the valve cover gasket, plugs, wires and any other oil soaked components.
When you remove the spark plugs, the oil will go into the cylinders. So, the vehicle might smoke for a while and be difficult to start initially. You can minimize this by using compressed air to blow the oil out of the holes before removing the plugs. When you do this, place a rag over the hole so the oil does not spray everywhere.
Let me know if you have further questions.
I would be glad to help you out.
However, I need the engine size. Also, is the vehicle all wheel drive?
This is actually a quite easy job.
First, remove the coils.
Next, remove the valve cover bolts.
Gently ply up the valve cover. Remove the cover off the engine.
Clean all mating surfaces to a shine being careful not to scratch the surface.
Apply black silicone sealer to the cap corners. Just a small dot not too much.
Reinstall the cover, bolts, and coils using the following torque figures.
Now, here's the trick to a good repair. Once assembled, wait a few hours (4 to 6) before you start the engine. This will let the silicone cure. This is also a good tome to change the oil and filter.
Of course, use a new gasket set. Replace the ignition coils or just the coil boots (if you can locate them).
Use only BKUR 7 ET (NGK) spark plugs. Or F6 LTCR (BOSCH). Do not use any other spark plugs as premature coil failure can occur.
Feel free to let me know if you have further questions. Please accept once you are satisfied with the answer. Thanks.
