After 7 years probably
if the spark plug wires go down the middle of the valve cover, it is DOHC. The Intake Manifold will also say Duratec. The OHV motor will have the spark plug wires connecting on the bottom of the head near the exhaust manifolds.
there are 2 wires coming in front of engine wear the drive belt is on the top of the engine push down on them and turn like you was changing a light bulb its under there
Changing the plugs and plug wires correctly has nothing to do with nor can it cause an oil leak.
The V-8s don't have plug wires, as traditionally defined. Each cylinder has its own coil attached to the engine wiring harness. They are located under the valve cover top panels.
If your looking at the valve cover on the engine you will see the the plug wires going straright in to the valve cover, obviously there are four. Those will be the plugs under the wires.
The EGR (exhaust gas return) valve is defective if you have eliminated the plug/wires, trottle valve etc.
Replace spark plugs, wires, air filter, fuel filter, spark plug wires and PCV valve.
Looking at the engine from the front of the car, the EGR valve is directly behind the valve cover (right side). It has a wiring harness connected to it with multiple wires. It sits straight down on the engine and is attached with two bolts. ( Note: the front of the valve cover is next to the upper engine mount)
If the old plugs and wires were bad I would expect the engine to start and run better.
on right hand side of engine,on drivers side by back valve cover.it is round and has wires going to it on top!
Disconnect the spark plug wires, disconnect the PCV-valve, remove four nuts holding the cover. Make sure that wires are not in the way. Remove the cover.
Had the same problem, try changing the plug wires, it worked for mine
The exat location of the spark plugs depends on whether you have a 3.0 DOHC 24 valve engine or a 3.0 OHV 12 valve engine. Follow the spark plug wires, which are the large grey colored electrical wires you see near the top of the engine. They will lead you right to the spark plugs.
The egr position sensor is made into the egr valve. Look for the egr valve and you will find a plug with wires plugged into the egr valve. These wires are for the position sensor and they go back to the ecm ( engine control monitor)< computer> James= 15 year Mazda tech just a tip= with engine COLD,reach under valve and press on plunger and see if it moves freely(not easy) but freely. Hope this helps.

The cold start valve could be checked by scraping the feed wires for a 12v input when the engine is cold. Use a tester for this. Put on the key to start for a half second. If there's no 12 v in the wires, remove the cold start valve and position it onto a container of gas. Aim a jumper wire from the battery positive line but do not touch it yet to the exposed wires leading to the valve and have somebody crank the engine for half a second, at the same time, touching the wire to the battery. Gas should squirt out. If no gas comes out, the coil is bad. Replace the valve. If gas comes out, the coil of the valve is good, but the thermo-sensor is bad. Replace the thermo sensor. It is normally found screwed into the engine block and the feed wires of the valve comes from it. -email@example.com
Try changing your spark plugs, and your spark plug wires.
could be oil from valve cover gasket or not changing plugs wires
There are no spark plug wires, this is a coil on plug system. The spark plugs are under the coils that bolt to the middle of the valve covers.There are no spark plug wires, this is a coil on plug system. The spark plugs are under the coils that bolt to the middle of the valve covers.
it is located to the right of the coils and plug wires on top of engine. facing it! it is a round cylinder shape. with wires to it on the top of it.
try changing the spark plug wires also
Yep you betcha! One of the best $25 you can invest in your engine. While you're at it, might as well do the plugs too. See "Related Questions" below for much more, with lots of tips and tricks on doing these replacements.
(5.4L only) On the (5.4L) you will see 8 coil packs.They are in the valve covers. On each side of the engine, on the valve covers, there are four black caps looking things with a bolt holding each one down on the side. Disconnect the wires from those things, which are the coils, and then remove the small (I believe 10 mm) bolt that holds it down, and then pull up on it. The plugs are under the coils. (4.6L only) On the (4.6L) you will see 2 coil packs.They are in the valve covers. On each side of the engine, on the valve covers, there are four spark plug wires on each side of the engine block. The plugs are under the spark plug wires.
hello the spark plugs are ressed into the valve covers follow the wires from the ignition coil packs. thx
The spark plugs are under the plug wires in the middle of the valve cover.
