Recently bought a boat with a cat 3208 t. When I got the boat home from the auction I took valve covers off and noticed the #8 injector had been pulled out and just placed back InThe hole. I Put everything back together both sides. Opened the drain valve on oilpan to check for good oil and I got 50 oz of clean coolant out of the pan and then just clean oil. I started the engine only for 40 seconds At a time and it ran very well but I noticed raw coolant coming out of the exhaust pipe. What do I do? No white smoke as I didn't let the engine get up to operating temps.
