What type of motor fo you have? 3800 lower intake are suppose keep coolant on the inside. If you have coolant in your cylinder and there are no apparent cranks along the wall. You wll have to replace your lower intake gasket. I recently did the job on my ponitac. But I also changed the head gasket seal aswell as my lifters and push rod. If you do the job yourself make sre you torque to spec or you will ahve to tear it all down again.
