Almost done with head gasket replacement. Since I know I pulled the original 1998 Honda head gasket from the car because I have owned it since June 2001, I thought it would be fun to compare the old with the new OEM. Inthese photos, the new one is above the old. See all the missing black material on the old one? The #1 cylinder seemed to be the worst. On the head and on the block, the worst contamination was around #1 and also #2, though it was not quite as bad.

Top of the gaskets, #1 cylinder is on the right

Bottom of the gaskets, #1 cylinder is on the left

Oil was getting into coolant, coolant was contaminted with combustion gasses, and a little coolant and maybe oil was burning. But no coolant ever in the oil.

"Reading" it, I see the day I first brought my daughter home, thousands of commutes, trips all over the country, including through the Hopi and Navaho reservations... across country, & 260,000 miles of never fail machine greatness.

Engineering is amazing. Precision factory production is amazing.
