Hello everyone I have some questions if anyone would chime in.. I recently purchased a used 2002 chevy camaro v6 for really cheap because of overheating issues, well I replaced the water pump and thermostat and problem solved. Well once I drove back to my house I had steamed cleaned the engine and heard bubbling noises, it came from the intake bolts on both sides it looks like from only two spots..my question is has anyone ever replaced the gaskets? If so is this a two piece intake?
