Re: oil in spark plugs
Change your piston rings. Check your compression. I'll bet that cylinder is more than 15% lower that spec.(all the others in the motor if its a older one.)If you just did that you will see some untell the rings seat. (if you made sure all the new ring gaps are not lined-up in the same place). If the oil was on the top of the plugs you fix whatever is leaking on them. If it was on the electrode, the above is true.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

With vehicle cold, recommend you first clean your entire engine compartment. Use a degreaser and then steam clean it completely. Once clean, start your vehicle and have someone inside run your RPM to about 2000 and you watch to see if you can determine where the leak is coming from.
I have run into these caravans burning oil, not much you can do except keep an eye on the oil level or spend a lot of money having piston rings replaced. The best way to go about finding the misfire would be to go to an auto zone or other auto parts store that will scan the computer for codes. the codes will tell you which cylinder is misfiring. I would bet it could be a fouled spark plug due to oil burning but could be a plug wire also.Have the codes read and find the cylinder that is misfiring and remove the spark plug and see if the tip is covered or worn down, if it is then replace spark plug and you may want to do them all. up to you. If the plug is okay then move on to spark plug wires, swap the misfiring cylinder wire with another cylinder and see if misfire moves if it does then replace the wires.
To find the cylinder by #. If you are standing if front of the van looking at engine cylinders 2,4,and 6 are in front, closest to radiator from left to right. then cylinders 1,3,and 5 are at the rear also going left to right. Good day.
have you put a new set of plug wires on it. use a spark plug tester, and put it between plug wire and dist, cap. if it is sparking you will see it. if yes and not to plugs put on new plug wires. good-day ! if above checks out. remove dist, cap and see if shaft of dist, is turning. some of the hondas have a plastic type drive gear on bottom of dist, shaft. that goes bad.
Poor performance from spark plugs and wires. mine did the same thing. I tried to change the spark plugs, and found oil within and around the spark plug boots, which is problematic, but not the actual cause of your problem. If you find this, your valve cover gasket needs replacing.
If not, just get new plugs and wires. Got that done and shaking almost disappeared completely.
I would change the spark plugs, spark plug wires, distributor cap and rotor, fuel filter, check and change air filter if dirty, check timing, check and top off all fluids, check or change transmission fluid, check brake pads/.shoes and drums/rotors for wear and check tire pressure, check the condition of all belts and hoses and replace as needed, check condition of radiator antifreeze and top off or replace as needed.
you need to check the check engine light first. then the miss can be from the oil on the spark plug i would replace that spark plug with oil on it and replace the valve cover gaskets this will prevent the problem from happening again
Pull the spark plug wires out one by one and check for oil on wire. Sometimes the valve cover spark plug hole gaskets leak oil into the spark plug hole and causes a misfire. If oil found clean with brake or carb cleaner and blow out with compressed air. also when car runs bad listen under hood for snapping noise this would be spark escaping to ground somewere. In a dark garage you might be able to see the spark.
not really the valve cover needs replaced get a valve cover gasket kit it will come with the gaskets that cover the spark plugs .if you let it go after a while it will contaminate or spark plugs wires and cause a misfire or your car will start missing.please rate this answer thanks.
