2000 Ford Focus 2.0 Liter SOHC.
The car ran fine. I started it the next morning and there was a god awful clanking noise comming from the engine.
I pulled the plugs. The #3 spark plug looks banged up.
The clanking noise is gone with the #3 plug out.
Today I put the #3 plug back in and the clanging noise is gone, but it still has a pecking noise.
If the valve seat is gone and pulverized now, should I still hear a pecking noise?
