And I forgot to add that my Cyl 6 plug's white insulator that is exposed to combustion was rusty colored whenever I took the plugs out BEFORE my head gasket. 1-5 were always in perfect condition. You can tell alot about how the engine is running by inspecting the spark plugs. The rusty color was from water getting in the cylinder. Now yesterday was the first day I had the new plugs out after the HG swap. I pulled #6......and it was clean. Looked just like the other 5. I was satisfied after I saw that. I could post pics if anyone wants to see the old #6 vs. the new #6. And I don't by all means baby this car around. Maybe until the oil temp get around 190 degrees, but after that its fair game and I do drive it hard.
