Oily Spark plug wire

[dave99]

Hello everyone,

I have this 1990 Accord EXR
Yesterday I bought those iridium spark-plugs and was going to happilly install them when I found out that one of the spark-plug holes where the wire goes has oil - maybe about 1-2cm or 1.5' the other 3 wires are nice and dry. So the end of the wire was all oily too

Now this scared the hell out of me, because I have no clue what could be wrong with this?

Any idea

Thanks,

David

Hey guys.

Here's what I found at:

Any other input anyone?


Excessive oil from leaking valve cover draining into spark plug wells and filling up to the bottom seals of extended multi-part plastic spark plug connectors can cause the bottom seals to un-glue themselves from the plastic extension tubes when the connectors are removed. The only real cure for this problem is to replace the leaking valve cover gaskets. Generally, if there is no crazed arcing tracks over the plastic extension tubes, the oil-soaked connectors can be re-used if you are able to re-glue (with RTV silicone adhesive) the detached seals to the end of the plastic extension tubes after the seals and tubes have been thoroughly cleaned with grease removing cleaner (do not soak them in a solvent), and as much as possible of the old RTV is removed. You can also send for new seals if the detached seals are too swollen. Alternatively, you can send the wires to Magnecor for new seals to be re-glued onto the extension tubes — please leave it to us to clean off the oil.

Just had all my seals and gaskets changed at the dealer, from the valve cover down to the head and oil pump and front and back balancer, no oil leaking no oil in spark plug hole....

Thanks,
My mechanic told me about changing the seals... although I found out later the reason why it was so bad, because he overfilled the engine on almost half a quart of oil.
Now after some of that oil burned away after around 2k I see improvement.
I think they overfill it on purpose to bring up the subject on replacing the seals.
Or maybe these people just can't do anything right...

There are 4 seperate gaskets under the valve cover, one for each spark plug tube... One of those gaskets is bad and that is where the oil is coming from. Just pull the valve cover off and replace those gaskets... make sure you put a new valve cover gasket on also.
