today I decided to look at my spark plugs cause i installed a new carb. and i was going to read the plugs to tune. All my plugs were good except #3 there was some oil on the threads and it slowly ran out of the whole. any ideas? i havnt noticed and significant oil loss it burns enough to add some by the time for a oil change.

 

anyone?

 

valve guides or piston rings

 

Was the spark plug dry on the end? Sounds like your valve cover gasket is leaking oil into the spark plug hole. Never seen a spark plug packed with oil and it not fire and burn it off when running. Technically blow by could cause that but there would be other symptoms. Do a compression check on the cylinder dry and with oil and compare pressures.

 

Sounds like just a leaky valve cover. A picture of the spark plug would probably give a better answer.

 

ill get a picture of the plug today but yea when i pulled it out the oil was only around the threads and not on the tip.
