SOURCE: cant find the spark plug location on 2002 4cyl tacoma

Locate the spark plug cover on the engine.On some Toyota Tacoma engines, the cover is across the top of the engine. On others, it is along the side 4 cyl. Remove the cover to reveal the ignition coils and spark plugs wires. The spark plug wires are plugged directly into the engine and the ignition coils are in the tip of the spark plug wire.
Remove the coil and wire from the spark plug. Twist and pull the plug out of the engine. Remove the spark plug from the cylinder well with a socket extender and socket wrench. Turn the wrench to the left to unscrew the spark plug from the engine.

Discard the old spark plug and apply a coat of anti-seize compound to the threads of the new spark plug.

Insert the new spark plug into the socket. Use the socket and extension to screw the spark plug into place.

Return the ignition coils and spark plug wires to the engine and turn it to lock the plug in place. Repeat the entire the process with the remaining spark plugs.

Replace the spark plug cover when all of the spark plugs are replaced.

Good luck and hope this helps and The spark plug tension may range between 11 and 15 foot pounds, depending on the size of the spark plug. The correct tension is indicated on the spark plug's packaging.

SOURCE: oil in the spark plug

You probably have a leaking valve cover gasket causing the leaking oil to collect in the spark plug tubes.
The miss fire is probably caused by the HT in the plug lead shorting through the oil and causing a weak spark.
Clean all the oil out and track down the 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.

Oil around the spark plugs


This is likely your spark plug tube seals. They come with valve cover gaskets because you will need to replace both in a job. You should also probably replace the spark plugs themselves, as the ends are probably fouled.

If you are interested in doing this job yourself, I would suggest going down to your auto parts store of choice and purchasing a repair manual for your car. Haynes is the book of choice, typically. It will show you pictures of the valve cover being removed.

Miss fire but no lights on changed the plugs and fuel filter also changed dist cap also checked for a good spark


A lean fuel mixture will not yield poor fuel economy but a misfiring cylinder will.You have already replaced the coils and the plug leads to the cylinders in question so they should not be an issue.Do the codes still indicate a misfire on cyls. 2 & 3? If so have you looked at the plugs? Has the oil leak around the plugs been stopped? Are they oil fouled? Could the pooling oil around the plugs be shorting the spark discharge to ground?or Valve Cover gasket is leaking. That's why you see some motor oil in the sparkplug sleeve (tube). removed the spark plug and My suggestion is to remove the sparkplug in cylinder 2 & 3 or whichever ones that the scanner indicated as "misfiring". Take a look at the sparkplugs and see if there's any oil around it. If you see any traces of oil, that means your gasket is worned out and need to replace.Good Luck in getting your problem fixed. If you need any further help - I'll try to help you the best of my knowledge and skills. You can repost on this

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 number 1 cylinder, fouling out plug


is there oil actually in the cylinder? or is the oil in the tube that the spark plug body lives in? if it's just in the tube, then you only need a valve cover gasket set which comes w/ a round rubber seal for the top of each spark plug tube. if however, the oil is actually in the cylinder, then you either have a faulty piston oil ring or faulty valve seals. the repairs for rings/seals are a giant PIA. let's hope it's just the valve cover gasket set

Spark Plugs


The oil on the spark plug usually comes from the valve cover seal or the spark plug tube. The valve cover seals to the tube and the tube seals to the head. The tube is usually a tight fit in to the head with a little sealant. The tubes can be purchased at the chrysler dealer or possibly at a local parts store. As for the red fluid,it is automatic transmission fliud . It is used in the manual transmission as well as the power steering system. You could have an axle seal leak, transmission shifter seal leak, power steering seal leak, depending on which side of the vehicle is wet.
