What will cause oil to ooze out of 3 of the 4 spark plugs? I have been having issues with the motor accelerating (picking up fuel on initial start) after the motor has been ran for a distance. Thought it was a fuel sending issue (fuel pump, fuel line hole, or primer bulb check valve) but just discovered the oil in the plugs. Any help would be greatly appreciated.

Thanks

that black ooze is most likely improperly torqued plugs or the fire ring(gasket) has been crushed to many times and can no longer seal.

Thanks for taking the time to post an answer to my question regarding the spark plug ooze. I appreciate the post, and I will check the torque for each plug.

torque wont fix a bad crush ring.
some call it a fire ring.
some call it a gasket.
typically they are a one use item.
they not only have to seal but transmit heat away from the plug.

I will replace and ensure new ones properly torqued.
