Hello, my car is leaking coolant looks like the front middle of engine. I was reading that the lower intake gasket loves to leak on these engines. My car is equipped with a supercharger. I will occasionally have white smoke from the exhaust.

Hi,

The lower intake manifold and upper plenum is a commend because with this vehicle antifreeze can leak into the intake ports of the engine causing white smoke. But be concern with the motor oil also antifreeze can also leak into the lifter valley and contaminate the motor oil causing bearing failure, The best way to find a coolant leak is with antifreeze tracer dye and pressurize test the system if you can. (Use caution when removing radiator or coolant reservoir caps system is under pressure antifreeze can cause severe burns) You will need to confirm where the coolant is leaking before making any repairs. I'm attaching repair guides below for checking coolant leaks and video on changing intake gaskets the torque is vital for good results.Please let us know what fixed your vehicle and if you need more information.
