really? why would it smoke white if the pump was bad, i understand it will have a loss of power but dont get the smoking part..
its dry as a bone.. I'm taking it off and welding her shut so no more coolerKeep the EGR cooler in the back of your mind. As mentioned, coolant leaking into the exhaust will cause white smoke also. A quick check would be to pull your EGR valve and see if it's wet /sticky.
And don't let the small drop in coolant foll you. 1lb of water will make ~1600lbs of steam. This is diluted by the mixture being 50% coolant, but you get the picture. A little bit of liquid makes a bunch of steam.
Yes, tested fine cold.Did you check your FICM voltage cold? Often a FICM will test 48v when warm but be much lower on a cold engine.
