my car wouldnt start so i checked the sparkplugs and 2 of them was filled up with oil . i took my valve cover off and my seals are good. and i replaced the plugs and cleaned up the oil what would cause this to happen anyone know.

 

If the tips of the sparkplugs are wet with oil it sounds like blow-by. Pull the head and take a look at the cylinders.

 

what do you mean by blowby

 

Whoa whoa whoa, don't go pulling off your head just yet. If your spark plug tubes are filling with oil it has to be one of two seals. Valve cover seal or rocker assembly 0-ring (lower tube seal. This subject has been covered at least 4 times in the past month. I know because I have posted this pic in all 4 of them.



Yellow = Upper Spark Plug Tube Seals (valve cover to rocker assembly)
Red = Lower Spark Plug Tube O-Rings (rocker assembly to head)

Your going to need to get yourself a Helms manual and pull the rocker assembly to get at the lower o-rings. If you do a search for this topic in the Accord forum you may find some good info. There was a thread on this topic that contained some very good tips & tricks a few weeks back.

Blow buy will only show on your spark plug tip. It will not cause oil to pool in your plug tubes. Unless your plugs aren't installed properly. In that case your plug wires would probably keep popping off from a build up of combustion gases leaking past the spark plugs.

 

thats what i checked i already took it off and they was fine can any thing else cause it...

 

no wait there is just 4 seals right when you take the cover off

 

Yes when you take the cover off there are only 4 tube seals. There are 4 o-rings lower in the tubes that can dry out and leak as well. They are indicated by the red circles in the above image.

 

cool i will check it out, i was worried there for a minute. i thought something major might be wrong

 

Wow great info and picture ghostaccord! I too have the same problem, replaced the valve cover gasket and thsoe 4 seals in yellow. I still had leaks and basically said forget it. Now that I know this I will try to fix mine. Thanks!

 

If that happens i would recommend replacement of the wires too. you dont want those to get soaked with oil.

 

If you are having oil in the spark plug tips from blow by, then I suggest replacing the PCV valve then as well.
