is your coolant always low, just a little bit? like 2 cups worth?
i was topping off my rad, every week or more, found the puddles in the bolt valleys, my plan is to get another engine and mod the crap out of it, so what i did was, i got a jar of bars stop leak, the copper lim and block sealer, and all my puddles dried up in 2 weeks, haven't added coolant in 2 months now too, and the car runs great, but i dont really recommend doing that if you plan on keeping this engine for the long haul.
