Check the water pump. The water will not leak all the time. Top your system off. Crank and run motor to operating temp. Turn engine off. watch for a leak as the car cools down. The water pump normally leaks on cool down. You may have to watch it up to 30 min. before it starts leaking. Also while it is cooling down, check for leaks in other places while it is still under pressure. Don't forget to check the A/C drain at the firewall.
If you still can not find the leak. You can put UV dye in the system. Let it leak. Then check for the dye. This will tell you where it is coming from without actually seeing the leak. But you will need a black light to see the dye.
If there are any leaks while cooling down, won't I see a puddle on the ground? I have done two intake manifold jobs on the 3.1. I have noticed that there are coolant ports. Could the coolant be leaking and going out the exhaust?
Are you seeing white smoke now?
No, But I have not changed the oil in a while. It normally looks black and dirty. But, now it's a creXXXXX XXXXX.
normally when the oil is creamy looking, you have coolant getting in the oil. On this motor. The most likely cause is the intake gasket. Is the oil level over full?
