Tuarus SHO, oil in sparks
 

Yeah I have a ford tuarus SHO 3.0 v6 5 speed manual. I have some oil where the spark plugs are, and was wondering what might be causing that so I don't have to tear the motor apart, and find the issue

My 92 sho is doing the samething oil where spark plugs are .I think maybe the valve covers are leaking but not sure either. sorry

hello and good day:

There is only one reason you have Oil on your Plugs.....Piston Rings...

RE: Tuarus SHO, oil in sparks
 

Are you saying the oil is on the outside of the plugs? If yes, there is a possibility the valve cover is leaking. If the oil is on the inside of the plug, first thing to do is to do a compression test. If it is very low on that cylinder compared to the others, probably rings.(130-130-130-50-130-130) If the compression is not very low compared to the other cylinders, look at the valve stem seals.(130-130-130-100-130-130)

Actually, this is rather common. Under your valve covers, around each spark plug, there is it's own gasket. It is rubber and fits on rather tightly. If you do a search for valve cover gaskets and see a picture of them for your model, they usually come with 6 of these gaskets also.

You should replace them as soon as you can, as it will interfere with the spark coming from each boot and cause an engine miss. Let it sit too long, and you will have to replace the wires as well.

To replace them, take off the intake manifold and remove covers. Rather straight forward and should take a novice about 1 afternoon to complete.

Yes you need to change out the grommets soon on each spark plug well, or it will cause major trouble

My Taurus is not SHO, but Flex Fuel.

I do not have individual gaskets around the spark plugs.

I changed out my spark plugs today, found some white/gray fouling on electrodes of 2 plugs, with an oil residue. Do not suspect head gasket, as NO coolant in oil. Have no way to do compression test. May be valve cover gaskets.

Any other ideas about this? Mine is not SHO, so may be different.

Posted another question here about replacing the expansion tube...it's leaking coolant as I wiggled it when replacing back spark plugs. Any experience with expansion tube, I'd love to get those comments.
