bad seals will most likely have smoke during startup or when u let off the gas.. i doubt the valve guides or seals would cuz ur drop in pressure on ur number one cylender but it is possible since u are seeing smoke when u let up off the gas. just seams a lil odd thats its only #1. if ur pressure didnt i ncrease during wet test and there are no signs of blowby then ur rings are still good.. when u take that head off check the head gasket around that bad cylender and put a straigt edge across the head and check to make sure there is no more then 3 thousands of a gap between the head and ur straight edge. use a feeler gauge for tha

u can also bring ur motor to tdc and apply air via the compression tester hose(dont forget to take out the stem) to the number one cylender and listen for where the air is escaping.. have something holding the motor from turning over.. i prybar works good or just someone under the car with a wrench.
Are you kidding me?
Wow -- the problem is either - the wet test was done wrong - Reading something and performing it properly are two different things.
Or - Your valves are not sealing properly - due to carbon buildup, or just a **** poor assembly job.
Or your HG is toast. Unlikely tho - as you would be pushing coolant.
