Car is nearing 20 years old. Relatively unknown service history but it runs and drives like a champ. I have two concerns regarding the passage of time and short trips on the car. The water pump is original (LT1 motor). It's bone dry underneath. Do I have to worry about the distributor taking an antifreeze shower within the next year? I'm aware they start to leak around 100k. I've already put 3k on it myself. And the transmission was last serviced in 2001 with 38k miles. SHould I service it before 60k is turned over?
