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
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.
Changing the plugs and plug wires correctly has nothing to do with nor can it cause an oil leak.
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.
Replace spark plugs, wires, air filter, fuel filter, spark plug wires and PCV valve.
The EGR (exhaust gas return) valve is defective if you have eliminated the plug/wires, trottle valve etc.
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!
Had the same problem, try changing the plug wires, it worked for mine
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)
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.
