Well, I finally got the oil pan replaced on the 300D. I also learned that while I'm working on a car, laying in oily water, and holding a flashlight in my mouth, I develop a severe case of Tourette's Syndrome. No doubt passing sailors could have taken notes to their advantage. I don't think I used the same epithet more than twice.
But it works now, so I am happy about that. We'll see what the Mobil 1 synthetic oil does for me. Otherwise, I'm driving the Fury III this weekend.
