My engine has been running poorly, lots of putting around at low rpms and around turns. I pulled and cleaned all the spark plugs, and they all looked fine except cylinder #1's. There was this sticky green **** on it, not excessive but it was on it nonetheless, and it took alot of swipes with a dry towel to get it all off. Now, the engine runs beautifully except occasionally around turns it put-puts again. Really annoying. This all started when I was going around a right turn at about 25mph at a normal driving pace when I heard a loud snapping/cracking sound from the engine bay. It still ran smooth so I kept going, but then I noticed around turns that it started hesitating.

Is that green **** anti-freeze and is it pouring into the cylinder when I go around a turn and thus causing Cylinder#1 to misfire? What else could that green stuff be?

Anyone had this experience before?

 

Antifreeze usually turns white when burnt on O2 sensors or spark plugs, but my guess would be yes. You probably have a crack someone in the headgasket/head/block.

 

Replace your head gasket first and if your still having the problem then I bet you've got a cracked head

 

i have to ask .. spark plugs are like 8 bucks .. why would you clean them? why dont you just buy new ones?

why wouldn't you clean them, a couple minutes cleaning is better than driving somewhere to pay money to get new plugs

I just barely had a similar experience - my #4 spark plug turned green. It didn't have tons of buildup on it though, just mostly green colored. Later on, I started seeing coolant leaking from the headgasket, just below the distributor. You will definitly have to remove the head, and inspect the block and head mating surfaces. Chances are it's a blown headgasket, but don't take anyones word for it - pull off that head and check it out for yourself!
