Was changing spark plugs this past weekend for driveability issue and the #4 spark plug (pax side by firewall) had coolant sitting in the spark plug well. What's this symptomatic of, and how how much will it cost to fix it? 1998 GT, BTW.
Check the plumbing running to your intake. I had a hose clamp back there tear a small hole into a rubber hose which was streaming coolant into the #4 plug well.
eww. That is exactly the spot i found my leak. It wasn't the hose though, there was a 1 inch crack where that hose connects to the intake manifold. It drips right on top of the plug. Sadness, hope its not that, sorry if it is.
