Replaced the spark plugs last night. That right rear plug is a bitch to get at. The original plugs still fired, but after 14 years it didn't seem like a bad idea to switch. The gap had grown to about .075, somewhat over spec. I'm hoping to gain a little better gas mileage with the platinum replacements. The right front plug was white instead of the tan color I was expecting/hoping for. Not just white on the porcelain cone, but all over! Does this mean a failing head gasket?
