Just replaced both intake manifold, valve cover, egr, and throttle body gaskets. It started fine and left it running a while everything seemed fine. Went to drive it home and noticed white smoke and the smell of coolant burning coming from right side of engine( side w/ throttle and thermostat). What could be leaking now????
did you have a leak before? is that what you did all that work for?
Make sure the system is full of coolant. Start the engine and let if idle until it gets up to normal operating temperature. Should be right around 210 degrees. then rev the engine to around 2000 rpm for 30 seconds. (That should put the system under pressure) then go out and look to see if you can see where the leak is coming from.
if that doesn't show you where the leak is coming from you should take to someplace that can do a coolant pressure test.
