SOURCE: oil around spark plugs on 1992 honda accord

Yes the oil can cause the car to lose spark, the oil leak could be caused by the valve cover gaskets around the spark openings, but 9 times out of 10 it is the spark plug tube "O" rings. The top of the valve train comes off of the head, the "O" rings are between the two halves, that will fix the oil leak.

SOURCE: 1989 tOYOTA CRESSIDA sAPRK PLUGS WELLS. OIL IN THE SPARK WELL

The 7MGE has 2 separate valve covers/gaskets with 8 screws holding each cover that will loosen over time.
Find the phillips screws holding on the covers and retighten snugly by hand do not overtighten!
Pull plug boots/wires by the boot not the wire and use paper towels or rags on a long screwdriver etc to absorb the oil from the wells.
Carefully clean plug boots with spray brake cleaner (avoid spraying anything but the boot) and let dry.
Apply 100% silicone grease to inner boot before reinstalling to allow future removal without damage.
If your engine is particularly dirty you may need to remove the covers first and clean all mating surfaces then reinstall.

SOURCE: oil around spark plug and car mis fires

The oil around the plug may be a sign that the valve-cover needs a new gasket. Oil on the plugs can cause a misfire but it is important that you check everything over. The misfire could be due to defective wires, boots, coils, spark-plug/s, injector/s, and so much more. Take a look at the cars maintenance history, Maybe it is over due for a complete tune-up or oil change. The car is 11years old, how many miles are on it? How was it running before this?

SOURCE: Oil leak around #1 spark plug of 2002 Ford Escape

Sounds like valve cover gasket is leaking. It leaks down side of engine onto everything in it's path. Stop by a local parts store and have them take a peak, they'll be glad to help you out.

SOURCE: oil around 1 spark plug well.

this could simply mean that too much oil has been added and overflowed on to the engine.if the vehicule runs well and is not noisy i would not worry about it. the spark plugs should be inspected to make sure they are seating properly.always start the threading of the plug to the head by hand.

Number 6 spark plug misfireing


Remove the spark plug and look at its tip. Most common causes of misfires:
  • Burned oil on the tip may be due to faulty rings or valves or just the PCV valve. In such cases the engine will smoke.
  • Gas on the tip means not enough power to the plug or a faulty plug (you may get a faulty spark plug even if it's brand new). If not the plug, the ignition system must be checked.

My plymouth voyager just started smoking


If its bluish smoke coming out of the exhaust, then engine oil is leaking past the piston's oil rings. You'll need an engine rebuild, or give its last rites before sending to the salvage yard. If it's white, it should clear up as the engine warms up. White smoke is caused by lack of heat temperature in the combustion chamber. If the engine is warm, and its still smoking (black smoke), then too much fuel is entering one (or more) of the cylinders, which is often caused by a faulty fuel injector. To diagnose which injector is faulty, remove and inspect each spark plug. Any Haynes or Chilton manual has a spark plug section showing what a normal spark plug should look like, versus one caused by faulty injectors.

Cause of oil in sparkplug tube?


1.your valve cover's spark plug chamber seal is leaking. Which requires removing the valve covers and replacing the gaskets and seals. 2. Excessive oil spills on to the valve cover and ignition coils when adding oil.

**This excess oil on the plug boots can cause the coils to short and eventually fail.

Oil in spark plugs


you mean oil under plug wires? your plugs are in the center of the valve cover? if so, you have a vlave cover leak, the oil will rise and short out the plugs so they will not fire. remove the oil from around the plugs, then replace the valve cover gasket and plugs, try to start again
