I have posted this problem before this 04 chevy silverado 4.8L it has been losing coolant for awhile now. It seems you have to add coolant every couple of days. I added dye to the coolant system and did a pressure test yesterday and found nothing and it held pressure, but seemed to blow a little white smoke out the tailpipe but later it seemed to stop does that dye cause a motor to blow white smoke? So what step should I do now were having to add coolant way too much and it has a new cap on the expansion tank. And I also did the combustion test to see if gases were in coolant and nothing. So what steps should I take now a compression test maybe?
