2007 ford explorer sport trac 4.0 v6 all 3 spark plugs on passenger side are coated in oil doesn't smoke 2nd set of plugs in 3 months driver side plugs are fine im tired of guessing anyone know?


comment exactly what you mean when you say --covered in oil
1-- is they covered in oil on the outside around the insulator and wires/ coils
2-- are the center electrodes black with oil and misfiring
if it the outside then replace the rocker cover gasket or if the plugs are recessed into the rocker cover , replace the oil seal under the plug tube in the rocker cover

My accord cylider 2 misses at idle what can be he problem?


If you replace the plugs,the ones that were made for your vehicle. And possibly spark plug wires, it should make quite a difference. Good-Day! It could be a injector making its rough idle on cylinder 2, But do above first!

I have oil leakin on top of my spark plug wires in the tube ive changed the valve cover gasket 3 times i even put high heat cilcone over around the spark plug tubes but all it does is slow it down im not...


Two things:

1. Make sure you torque the bolts down to the right specification, which is 83 inch pounds (or about 7 ft lbs). Work opposite end of the cover and start with a lower torque first (like 50 in lbs), then go up to 83. It's just a good practice.

2. If that does not work, get a Fel Pro gasket set VS50365R (pic below). What is special about this set is the really thin o-rings there in the middle. Those are the rocker arm tube seals. You need to take the rocker arms off in order to replace them, but this way you're doing a complete job and you probably won't have that issue again. If you don't want to get the whole set again (since you already replaced most of it 3x over), you can probably just go to a honda dealership and pick up the 4 you need.

Here are the seals under the rocker arms:

If you decide to do this yourself, it's a good idea to get a set of feeler gauges so you can properly gap the clearance from the rocker arms to the valves. Intake valves should be gaped to .010 in, and exhaust valves to .012 inches. Also, yes, you can take the rocker arm assembly off without removing the distributor...just take off that one bolt that is in the way. The torque for the bolts holding in the rocker assembly is 9 ft-lbs for the smaller 6x1mm bolts and 16 ft-lbs for the larger 8x1.25mm bolts. Here is the torque sequence...

I replaced the lifters in my 2000 galant 2.4 L and i need to know what to torque the rocker arm shafts to.


1.5 and 1.8 engines:
* Install the rocker arm and shaft assemblies. Tighten the rocker arm shaft retainer bolts to 23 ft. lbs. (32 Nm).

* Check valve adjustment and install the valve cover. Tighten the valve cover bolts to 16 inch lbs. (1.8 Nm) for the 1.5L engine or to 29 inch lbs. (3.3 Nm) for the 1.8L engine.



2.0 engine
* Lubricate the rocker shaft with clean engine oil and install the rockers and springs in their proper places.

* Install the rocker shaft assemblies on the engine. Tighten the bolts gradually and evenly to 21-25 ft. lbs. (29-35 Nm).



2.4 engine

Fig. Rocker arm shafts and components-2.4L engine



* Fit the rocker shaft springs from above and position them so that they are at right angles to the plug side. Install the rocker springs before installing the exhaust side rocker shaft and rocker arm assembly.

* Install the exhaust side rocker shaft assembly in the engine. Tighten the rocker shaft mounting bolts gradually and evenly to 23 ft. lbs. (32 Nm).
* Remove the lash adjuster retaining tools.
* Install the rocker cover and tighten the mounting bolts to 30 inch lbs. (3 Nm).

* Reinstall the spark plug wires to the spark plugs.



Hope helps.
