leaky post

[randmc]

I just picked up a reconditioned keg from the lhbs and its got an issue. The keg holds pressure just fine, but air is leaking like crazy somewhere in the connection from the in post. I just put some keg lube on the o rings but that didn't seem to fix it. I've got some new rings on the way but if this doesn't fix it what else should I try?

Is it leaking from the base of the post or popit on top? use some soapy water (old leaky tire trick) to locate where the source is. Most of my keg issues have been popit and o rings.
