    Hi, no abnormal oil use, no smoke - i don't think it is the rings. Im unsure of compression ratings too :(

    The prev post was the car is not starting, we have since figured that the fuel pump is not working, wether it is stuffed or it's not receiving power is now the question. Could the oil on the plugs be a build up from trying and failing to start the car soo many times?



    Do you know how to test the fuel pump for power? I have not had the car for long so i am unsure of where things are located - like relay's etc?



    Thanks!

    We determined that the pump is not working by testing all the little things fuses etc and following the fuel lines from the engine to after the filter (to see if filter was just blocked). and then from there back again to see if the pump was buggered. It's not making any noise when you turn the ignition (it's supposed to buzz?). And it started playing up, not starting etc a couple of days ago - but then it was fine. Which leads us to think that it's an electrical prob, loose wire etc? And that loose connection has now become a severed connection somewhere. I heard that you are supposed to check the relay's etc? Can you please tell me how to do this? Or do you know of a series of tests that one can perform to determine if it's electrical or a new pump is needed? I would rather not replace the fuel pump unless we can be absolutely sure that it's the problem, not the wireing leading into it... :)



    Thank you for your help.

    I may have missed a previous post but how many miles on this vehicle? Have you checked the compression on each cylinder? How much oil are you using? Are you leaving a smoke trail out the exhaust? Any sign of oil leaking out around the valve covers? Is the PVC valve all clogged up with oil?


    A little more info will help the diagnosis.

I would suggest that you solve the fuel pump problem and then see if the oily spark plug problem goes away. You say that the fuel pump is not working. May I ask how you determined that? If you know for sure it's not working, suggest you replace the fuel pump and then see what the next step is.


good luck Loringh

    The way I would check the fuel pump is to make some voltage measurements with a voltmeter. If the pump were the intermittent problem one could see the voltage fluctuating on the meter. Unfortunately,
    the electrical problems require the correct instrumentation to troubleshoot.

    Perhaps there is a place where you can get a fuel pump, say a junk yard where you would not have to spring for a new one.

    Good luck Loringh

Where are the Spark Plugs located in a 2004 Lincoln Navigator?


Hello, first how many miles do you have on this Lincoln? On that 4.6 L V8 engine they do have spark plugs but each plug has it's own spark coil located on a long rubber plug. You will see four little coils on each side of the engine. There will wires going in to the individual coils. There will be a bracket the holds the coils in place with a small 9 or 10 mm nut. Remove the nut, and gently pull on eac coil. There Hello, first how many miles do you have on this Lincoln? If you have over 120 thousand miles on this engine then it might need new spark plugs. On that 4.6 L V8 engine they do have spark plugs but each plug has it's own spark plug coil. You will see four little coils on each side of the engine. There will wires going in to the individual coils. There will be a bracket the holds the coils in place with a small 9 or 10 mm nut. Remove the nut, and gently pull on each coil. There a long rubber plug that fit in each spark hole. These rubber plugs are about 4 1/2 to 5 inches long.


Before removing the plug use an air hose with 50 to 60 lbs of pressure to blow each spark plug hole out which might have foreign object in the hole. Why, if you remove the spark plugs, and there is foreign material in that plug hole. Guess what, that stuff will fall into the combustion camber.



Then you will really have some problem. How fix if stuff fall into the combustion camber.

Squirt small amount of oil in the combustion camber, unplug all the coils and clear out there plug hole. Now remove all the spark plugs. Now, you can crank the engine and will the little amount in that cylinder that has the junk in it. The oil will wet the foreign debrie, and blow it out the spark plug hole. Then use a clean rag with with some oil it with a long screw driver to clean that spark plug hole Be careful that don't push the foreign material back into the combustion camber. Do this several time with little amount of oil.



Now, you can install the new spark plugs. On the spark plugs threads use some anti-shiz grease. Why squirt oil into the combustion camber? The oil is used to seal the rings on the piston to increase the cylinder compression. Just a small amount goes a long ways. GB...stewbison

What Is Recommended At 90000 Mile Tune Up For Chrysler Town and Country


At this interval it would be a good idea to check your drive belts, coolant hoses, motor mounts, suspension bushings, check for any motor oil leaks which could occur from any leaking gaskets. It is also a good idea to have change your spark plugs at this point as well. Normal spark plugs last around 50k miles before there electrodes start wearing out and losing their heat index value. They may still be functioning but at the cost of a lower grade spark and less than optimal fuel economy. If you've never replaced your power steering, brake, and transmission fluid and filter now would be a good time. I'd recommend replacing with synthetic grade fluids. I'd also recommend changing your motor oil on any vehicle every 2500-3k miles and adding a quality motor oil like castrol or valvoline, I personally use and recommend stp oil treatment, 1 bottle added at every oil change as well as marvel mystery oil in both my motor oil and added to my gas tank, this is remarkable stuff which keeps the internal components of your engine and fuel injection system clear of residual build ups. Be sure to also check and replace if necessary your air filter as well. good luck and hope it lasts another 90k miles for you

2001 mitsubishi montero limited light on service engine soon 110000 milege burning smell from engine oil ok transmission oil ok coolant ok


look hard around your valve cover or your spark plugs holes especially #3 and #5. i found mine on 3 and 5 spark plugs. oil sometimes drip down to hot eng and smell like burn oil. possibility your valve cover that seal your spark plug hole is worn out and leak around the valve cover and straight down to hot area. replacing valve cover gasket is not easy and if you take it shop will cost you over $1000.00 because of intake manifold and a lots of hardwares to remove. shop around before you take it to the shop. if you do it your self with a friend make sure you take picture for every lines ,bolts sensor plugs and so on you remove. also may as well tune up or change your spark plugs. good luck

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?

Cyl#3&5 foul plugs 97 suburban good compression all cyl new cap rotor distributor wires plugs module


Fouling occurs when the spark plugs' firing tip becomes coated with excessive fuel, oil, or combustion deposits so that it is unable to produce a spark. A plug can become fouled from continuous low speed driving, improper spark plug heat range (too cold), improper timing (over-retarded), too rich an air/fuel ratio or an oil leak into the combustion chamber. A variety of self-cleaning features are designed into most plugs to reduce fouling.

Motor Oil in with spark plugs, backfiring and stalling.


hey i actually just dealt with this problem last week ona friends car. the oil in the center with the spark plugs is because you need a new valve gasket. not a cover unless its cracked just the gasket and it costs about 25 dollars at your local parts store. its very easy to install and a quick fix but try to get all the oil out of the center as you can and rub a little bit of old oil on the gasket before you install it. it helps stop dry rot. try this first and then see if the backfiring and stalling stops. if not, you may need to change your spark plugs again even if you already have because chances are the oil thats already in the hole has burned up the spark plug. so give your spark plugs a good check while you change your valve gasket.
