Yessir, Eric'* joyride (I was driving at the time, but he had earlier) is what FINALLY did it. The amazing thing is that something didn't let loose at the Dragstrip this summer. I fully expected. Zilla'* valvetrain has 120k miles on it, and needed refreshing anyway.
Believe it or not, she'* still drivable, and I do make short trips (or have been the last couple weeks, as I'm only 2 miles from work). Wouldn't you know, the 95 chose this time to do the MELTDOWN in General Chat.
