coolant on spark plugs

hardhitter · January 26th, 2009, 05:37 PM

I pulled out one of my spark plugs after a recent intake manifold change and its got coolant on it.. is this from a leaking intake manifold gasket?

dude everytime you post a thread it reminds me of my car!!!! Swear... One of my plugs smelled like that a while back when mine was missing. Since then i just changed all the COP's and it hasnt came back yet but who knows. I guarantee you tho that i smelled antifreeze on the plug and it even looked wet.

On the tip of the plug or the part that the COP goes on?

I would re-seal the intake if I were you.

It was on the tip of the plug but I replaced it and pulled it out again and it's dry now

Should I change the spark plugs if they're white?

Check the oil and coolant to rule out a HG, then you may want to double check the intake gaskets. New plugs is never a bad idea. I figure that i'f i'm going to check them i might as well put some new ones in for $30.
