Spark plug tube seals -- just a buck or so each. If that doesn't do it -- it's leaking in around the valve stems and you need the head reworked (it would have to be REALLY bad to let in enough oil to prevent spark).
So you have oil on your spark plugs and you have checked all of the seals and none are leaking??i checked the tube seal they were fine and it just happened out of no where i was sitting in a parking lot and the engine just shut off there was no smoke or burning oil smell if that helps also
Is oil on all 4 of your spark plugs? Have you removed the valve cover recently? Is anything wrong with any of the plug tips other than being covered in oil?well the oil is all over the spark plugs when i pull them out and every now and then when i try to crank it it will give off a loud pop but not start
Agreed 100%. I have had 3 leaking seals. I was only able to see a flaw in one of the three. Just replace all of them at the same time and be done with it. They are only like $2/ea from the dealer.How can you look at a tube seal and just know that it is "fine"? I'd recommend just replacing them anyway.
I may have found a replacement for the stock valve springs, only beefier.....well thats just an excuse to do head work lol
