The pitted pipes are a result of acid buildup in your coolant system. When was the last time you flushed out the coolant system? It should be done every couple of years. Call a DeLorean vendor and order a new pipe. Also, have you replaced the coolant system rubber hoses, ALL of them. Including the ones under the intake manifold. This is where most coolant losses occur. Poke a long screwdriver or stick under the intake manifold and see if it comes up wet. If it is, then the next step is to call PJ Grady and get his coolant system hose kit.
