I have replaced the timing cover when I replaced the front cover gasket because it was coroded and warped. I also loosened the oil drain plug to see if coolant was still going into the oil and saw none drain out. I have verified the tester on another vehicle and it holds pressure rock solid. On the f250 I have a hard time even getting it to pressurize at all.
Its like trying to pump up a bicycle tire that has a pin hole leak and as soon as you stop pumping it starts to leak down. But like I said before it is rock solid when the truck is at temp.
