Coolant in #2 spark plug hole of Zetec.
And yes, it's coolant. I dried it out yesterday (small puddle around spark plug hex at time) and today it's moist again.
The spark plug hole on forward (exhaust cam) side looks moist as if coolant is seeping thru there......
But I'm hoping that the hex head bolt just to the left of #2 (towards #1) isn't a bolt but a plug for the coolant system. (looks slightly corroded, but was dry today and yesterday). If it's a plug, I think it's the leak.
Can someone tell me if this is a PLUG (please be yes) or a head bolt?
