i just got my car back from the mechanic. i had it done. i dont know when the last time my waterpump was changed if ever. the thing was almost seized up. it run so much smoother now. i got new timing belt, water pump, tensioner, rotor button, dist cap, crank and cam seals, valve cover gasket, and new drive belts. it is worth getting it done if you never have. o yeh i also got the valves lashed and set to spec.
