I've already swapped the plugs, which were all covered in oil. I would imagine from high mileage. |
I've swapped coils back and forth, they are all working.
I've also swapped injectors, and they are all flowing
Hi, GSREX....if you have oil in the very tip of the sparkplugs, your car would definitely be smoking....are you sure it was not just excess oil that dripped down, because the valve cover gasket is known to harden, crack & then leak down in this area.....also, wondering if maybe the CEL bulb was maybe removed....or maybe just blew out...easy check would be just to turn the ignition switch on.....I do agree, if the engine was running on 5 cylinders, there would be a CEL. In reading everything you have done so far, such as:
So, if you are sure you have heavy black oily carbon deposits on the spark plug electrodes & in the combustion chambers, this would tell you that the engine is burning oil. The most likely cause is worn valve guide seals and/or guides, but worn rings and cylinders can also allow oil to enter the combustion chamber. The only way to be sure is to do a compression test on each cylinder......I am not so sure this your problem though, because like I said you would have a smoking condition.....???
Johnny, Thanks for your input it is Greatly appreciated. When I first pulled the plugs, they were just drenched in oil. More so on the bottom from the combustion chamber, but the grommets on the valve cover are also obviously leakin a tad. Oddly enough, there is No smoke. Not upon start up, while driving or under a heavy load. Nothin. I figured maybe someone had disconnected the CEL light, but it does turn on when the car is in the "on" accessory position.
