Hi guys, first post here. I have a 2005 F250 with the 6.0 powerstroke. Truck is loosing coolant at a fast rate with no visible leak even after pressure test. White smoke only on initial acceleration during cold start. Replaced oil cooler with OEM oil cooler and gaskets less than 1k miles ago...

Alright so I have a 2004 ford f250 6.0l FX4. about 2 days ago I was putting a load on the motor going up a hill and it died. figured it was a cam sensor so changed it out yesterday which fixed the problem. When i pulled it out it had a thick glob of what looked like oil on it. so put a new one...
