well mike I already replaced the gaskets because I had oil in the wells. do you think that the oil fried my wires. They are nkg's I really don't like them do you recommend another brand? What plugs do you use? I just ran out side to check the wires and two of them are dead.
When I posted my reply, I "proof read" it and then looked at your post again and realized your sig indicates you've got NGKs now. When I wrote my reply, I was assuming your might have still had the factory wires. To be sure, the OEM wires are weak, unreliable and short-lived. NGKs are not known for short lives, but when immersed in oil, who knows...
Having said that, I see you've tested (can you describe how you tested them?) two of your NGKs and indeed found them "dead". Did you measure the resistance of the wires, end to end?
A DC resistance check will only uncover one of several failure modes a plug wire can have. Another mode, cracks and insulation breakdowns along a plug wire's length, can let spark energy leak out to nearby engine parts (e.g. valve covers), reducing the spark available to the plug. This is one cause of misfiring and rough running. A DC-open (likely what you measured) can also cause problems because the spark energy now has to jump another gap in the system - where the break is - which again reduces spark plug energy.
The oil in the wells may have damaged the NGKs. I honestly don't know how resistant they are to hot oil immersion but it's safe to assume it's definitely not
good for the wires.
If the wells are clear of oil now, put a new set of NGKs on. If you've got oil in there, get that fixed, then put a new set of wires on. While you're in there, you might as well put in a fresh set of plugs too.
FWIW, I too run blue NGKs on my KL03 and have done so for perhaps 3 years now with absolutely no trouble at all.
