Default Just changed my spark plugs...

I replaced all my spark plugs with NGKs and have a few questions, the third one was dripping water when I pulled it out, but my engine runs fine and I dont see any signs of water in the oil, and the fifth one was completely covered in oil when I pulled it out. Just wanted to know if you all think I got a oil leak or what? And what could cause one plug to be covered in water?

And for the water... Check your throttle body coolant lines for leakage.

I by-passed the throttlebody coolant lines years ago. Just use a metal or plastic connector to hook both hoses together. Then get a couple of large vacuum caps and put onto the TB fittings (looks better, and keeps dirt out).

I recommend doing this to everyone. The ONLY reason coolant is run thru the TB is to warm it up sooner for a little more emmisions control. BUT......The cooler the air going into the engine, the better it runs, and more HPs.

Which lines are the coolant lines? I have pulled my throttle body off a couple times to change my plugs then my plugs and wires. I only seen 1 coolant line. If you have a diagram or picture Mrnickeye it would be great. Please put it up.
