How do you fix when oil is getting in one of your spark plugs and not letting it fire?

either a bad ring, or maybe bad valve seal. sounds like a trip to your local mechanic is in order.How do you fix when oil is getting in one of your spark plugs and not letting it fire?
Sadly the rings on that particular piston are shot. You are up for an engine rebuild to fix it properly. You could try various potions to stop smoking etc, but these are temporary and in your case unlikely to work at all.





Sorry for the bad news.How do you fix when oil is getting in one of your spark plugs and not letting it fire?
a temporary fix that will really work is to create a 1/4'; air gap between the plug wire and the sparkplug top electrode. this is usully done by pulling the wire up into the boot as far as it will go without falling out. it makes the coil develop a BUNCH of juice before it jumps that gap. It wont hurt anything .
Oil on plugs, if you are lucky, renew the cylinder head gasket, or if not, completely strip the engine, and replace the piston rings!
Try a hotter plug with a good stand off...


You may have a leaking valve guide, a bad ring or even


a hole in a piston...


Do you have much blow by out of your valve cover ?
bad valve guides ,leaky valve seal,blow by at the piston rings,or maybe a worn out engine. cylinder walls worn,etc.


REPAIR: rebuild or replace engine.
If this is a Dual Overhead Cam (DOHC) engine then you can forget all the gloom and doom posted above. Of course, it would have helped, like so many questions here, if you had included make/modle/year/engine.





On a DOHC engine the valve cover has holes down the center to allow the spark plugs to be inserted in the cylinder head. The gasket set for the valve cover on a DOHC motor includes not just the normal gasket around the rim of the valve cover but also a small round gasket to seal each one of these holes. If one of those gaskets starts to leak, it will allow oil to fill the hole in which the spark plug is insterted, shorting and fouling the plug.





So what you need, if you have a DOHC engine, is a valve cover gasket set.





If you don't have a DOHC engine, well, then your in trouble and I just wasted 4 minutes of my life.
try using a NGK platinum tip they work pretty good for that.
your piston ring's shot. change your oil often it's gonna be full of gas and blow up your crank case. unless you're fixing the engine, best thing might be to disable the fuel injector somehow so it doesn't keep squirting gas down in there
