Cause of oil in sparkplug tube? - 2001 Lincoln LS

THIS IS EASY REMOVE THE VALVE COVER TURN IT UP SIDE DOWN POP ALL CIRCLE GROMMET OUT WITH FLAT SCREW DRIVER INSTALL NEW ONE. YOU HIT THE OLD ONE FROM THE TOP DOWN . THE NEW ONES FROM BOTTOM UPWARD WITH SOMETHING FLAT NOT RIP WHEN HIT NEW ONES IN. HALF HOUR JOB

No it isn't..the problem is caused by failed spark plug seals on the valve cover. There is a seal for each spark plug tube and the ends can get brittle and allow oil to seep into the tubes. You can get new ones at most any auto parts store and the are easy to replace. Another way for oil to get into the tubes is if the vavle cover is taken off and when it is put back on the seals aren't "worked" around the tubes. When I do it I use a very thin screwdriver and go around each sparkplug tube to make sure the lip of the seals is not caught by the tube and cut.

This sounds like bad sparkplug wires, pull wires off the plugs and see if oil is on wires, this is common on these cars the valve cover gasket goes bad and oil leaks into sparkplug holes and then it misfires, if theres oil in holes replace the wires and the valve cover gasket with the tube seals,

The oil may be causing the misfire,you will need to replace the valve cover gasket and sparkplug tube seals, the oil leaks in from the tube seals,also make sure to clean hole out after the repair and make sure the coil is still good, you may have to replace the coil boot if its soaked with oil,

The cover will need to be removed prepared for the new seal & re-sealed. When you look at the gasket set you'll need for the job, you will see the seals that keep oil from leaking in around the plug area. You'll also want to check & make sure you don't have back pressure coming from a converter that is going bad or has passed that point already, that's a major cause of seals to leak, that and the heat in the head of the engine caused by the exhaust blockage.

Good luck.

this means the valve cover needs replacing, when replacing the gasket make sure you replace the sparkplug tube seals this is whats bad on your, also make sure you clean the oil out of the holes and clean it of sparkplug wire also. you can use brake cleaner and then blow it dry with air.

To fix this, the valve cover seal needs to be replaced. It is not the cover seal itself but the four rubber seals under the cover that keep oil out of your spark plug tubes. This is a simple fix and do not use silicone for any part of the repair.

you need to reseal the sparkplug tubes. this requires removing the valve cover.the flashing check engine light means the converter is overheating due to unburned fuel going to the exhaust.

thread dammaged in head causing spark pug to come loose can fit heli coil to fix thread in head so spark plug wont come loose and leak oil into tube. other places oil can come from to cover plug in oil
remove rocker cover then remove spark plug tube they are screwed into head and clean thread of tube and apply sealant loctite to thread refit to head and may pay to replace seal for top of spark plug tube that is in rocker cover
one of these or both can leak, if tube is tight in head it may not be leaking the top seal is

Sounds like one of two things. One is it has had oil spilled while adding oil and it has ran down into the chamber by gravity. The other is a leaking valve cover gasket.
