A/C leaking

YARRR SUBY MONSTER!!
My A/C has been getting worse and worse. So I got a recharge bottle from napa, charged it up, and it worked awesome!!

But I've noticed it slowly over the past few weeks starting to fade again

I figured there has to be a leak somewhere... and there is. The valves under the blue caps in the system on the high and low pressure line are leaking. When I take the caps off I hear a pop as pressure escapes, and when I look at the valves, in both high and low pressure, I can see foamy stuff in them. Bubbling up. Even when the car is off. So I can basically watch the system sit there and actively leak.

What can I do about this? Do I have to replace the lines to fix this problem? Can I get some sort of cap to screw on that will make a tight seal to keep the refrigerant leaking out the valves? This seems like the easiest option. Does such thing exist?

thanks.

 
those caps are just dirt/dust covers, they shouldn't be sealing the system. sounds like you may have crud in the fittings, maybe try a lil brake cleaner and/or shoot em with a air hose

 
there simply shrader valves that screw into the high and low side...there just larger than normal ones you might find in valve stems.....as nigel said you may have some debris that's built up in there keeping the valve open...if you cant clean them out they can be removed with the right tool and youll just have to recharge your system again.....side note.....dont over charge or under charge or your ac wont work.....

 
i know the blue caps are dust caps. i was thinking maybe i could get different caps to seal it... and i know i charged it right. i have gauges and stuff

 
They have new valves and the tool at Napa or you can borrow mine. It takes 1.75 minutes to replace both if the system is recovered/empty. The caps are designed to hold some pressure but they cant hold a leaky valve pressure

 
I was thinking about getting different caps that actually sealed... but it sounds really easy to do! I wish I had known to replace the valves when the system was empty. After I get back from MA this weekend I'll look into how to recover and replace the valves. I didn't realize it was going to be so easy! Thanks inski!

 
no sweat. Stop by Evergreen if you want to borrow the tool. Basically its just a screw driver with the blade cut off and a slot cut in the stem.
