If oil was just around the plugs you have a oil leak somewhere . If the tip of the plug that goes in the motor is covered with oil it is either worn valve seals or piston rings. If it leaking oil look at the valve covers this is on of the most likely place for oil leaks.

How to change the spark plugs on my 2009 Hyundai Sonata 4 cyl.


remove 1 spark plug wire from the plug. Find a socket that fits the spark plug and connect it to the socket wrench. Put the socket on the spark plug and turn counter clock wise until the old spark plug is removed. Check the gap on the new replacement plug ( make sure you have the correct plug first). Put the new spark plug into the hole that the old 1 came out of and turn clockwise by hand making sure it is in straight, then tighten it clockwise until tight.( WARNING: DO NOT OVER TIGHTEN THE PLUG OR YOU WILL BREAK IT). replace the spark plug wire. repeat the process with the other 3 spark plugs. Start the vehicle. If you are replacing the wires, take off 1 wire at a time, match up the size and replace the old with the new.

I need instructions on how to change spark plugs and wireset on a 1995 subaru impreza l 1.8


Since you are unfamiliar with this process, do these steps one spark plug at a time. Locate the spark plugs; remove the wire's connecting cap from the plug; remove the spark plug from its threaded hole (use a dedicated spark plug wrench or socket of the proper size - may be a 16mm, 5/8", or possibly but unlikely 13/16"); check the electrode gap on the new plug and install it in the threaded hole; follow the plug wire back to its individual coil (opposite end from the spark plug; remove the old plug wire and replace it with the new one of the same length ensuring the same wire routing; replace the plug wire cap on the new plug; move on to the next and repeat.

What do you remove to have access to spark plugs


Tools you will need before you start1. 1/4" ratchet2. 1/4" extention3. 10 mm socket, 1/4" drive4. small flat bladed screwdriver5. 3/8" ratchet6. 3/8" long extention7. 5/8" spark plug socket, 3/8 " drive8. air compressor with blow gun or can of compressed air9. long needle nose pliers10. 1/4" internal diameter rubber hose 8 inches long11. wire coat hanger12. neverseez lubricantProcedure1. Remove the two 10 mm cap nuts on the top plastic housing over the engine2. Remove the two fasteners on the back of the housing and remove the plastic cover3. You will see four plastic blocks with four wire clips on each block. These blocks are individual coils for each sparkplug.4. Use compressed air to blow out debris around the blocks5. Use the small flat bladed screwdriver to carefully lift up on the tab that holds the electrical connector onto the block and slide the wire clip off the block.6. Remove the 10 mm bolt that holds the plastic block onto the engine. Use the needle pliers to firmly grasp the plastic screw and pull straight up to remove it
7. Loosen the 10 mm nut on end of the plastic rail that holds the wiring harness for the blocks so that the round plastic washer on the bottom of the block will not break when you pull off the block8. Carefully pull the plastic block out of the engine. There is a 4 inch tube attached to the block that extends into the engine to the spark plug. It will take some twisting and pulling but you must be careful not to catch the back part of the round plastic washer that you cannot see, on the bottom of the plastic wiring harness.9. The spark plug is at the bottom of the 4 inch hole.10. Blow compressed air down the hole to remove debris11. Use a 5/8 sparkplug socket with a rubber collar on the 3/8" extention to remove the spark plug. The rubber collar will hold onto the spark plug as it is removed.12. The NGK website recommends making sure the spark plugs have the correct gap .044 but the spark plug box says not to adust the gap because you might damage the needle point iridium tip. The new spark plug has a protective cardboard tube that is removed.13. Spark plugs can stick inside aluminum heads and break off when you try remove them, leaving only the threads of the plug inside the engine which will necessitate removing the head to remove broken spark plug. Putting neverseez on the threads of the new spark plug will prevent that in future spark plug changes14. Now comes an interesting choice. You can use the rubber tube over the neck of the spark plug to slowly drop it down the hole and hand tighten it or you can use the spark plug socket with the rubber collar. If you use the spark plug socket, the rubber collar will stick to the plug and you will pull off the extention, leaving the socket in the hole. A pair of long needlenose pliers will reach into the hole and remove the socket, but the rubber collar may remain on the plug and you will have to bend a piece of coathanger with a short 90 degree tip to reach into the hole and pull out the rubber collar. The rubber collar is there to prevent you from cocking a regular 5/8" deep socket at an angle which will break off the neck of the sparkplug, necessitating another 10 dollars and another trip to the auto parts store.15. After the spark plug is hand tight, give it 1/2 turn more.16. Replace the square block, being sure that the black silicone gasket on the bottom of the round plastic washer does not get bound up on the engine post where the 10 mm bolt goes. Tighten the bolt17. replace the electrical clip.18. Go to the next spark plug and repeat the procedure.19. After the last spark plug is done, be sure to retighten the 10 mm nut on the wiring harness rail20. Replace the plastic cover over the engine and you are done

How do you change spark pulgs in 2004 f150 v8


Remove coil wiring and one bolt 7mm loosen and remove with a magnet dont drop the small bolt. Slowly twist coil back and forth and pull at the same time removing coil DO NOT Remove spark plug if emgine is HOT. YOU must blow out all durt and sand from out around spark plugs if you dont sand and durt will fall into engine. Then brake loos spark plug if plug dosnt come loos DO NOT fors it. Us lite oil wd40 or atf 6 or 8 drops. and work plug back and forth until you work it loos and remove it you must tack your time. Do this with hand tools only! (Not air tools). To install new plug us a rubber hose 3/8 fuel line will work 6" long to start the pluge in the hole then tork it down. (DO ONE AT A TIME) tack your time I like motorcaft plugs no come backs.
