Freon Leak on a 2002 Disco Series II

Well I just replaced my oxygen sensors (btw add that to the list of things I don't ever want to do again) and now I am losing freon...
First I had to recharge it once a year and then it is every 2 weeks and now I lost all my pressure in a day. Any Ideas on how to troubleshoot and any usual suspects?

Spray your motor down with degreaser really well, especially around the compressor, all lines to con/firewall, condenser and pick up a can of r134a at the auto parts store that has uv detection dye in it. not the cans with oil but just dye. 1, 1lb can should be enough with it leaking that fast to find the problem. charge to the low side and when the compressor stops kicking on, look for the area in the system thats oily and or green from the dye. if there is no area under the hood thats turn out leaking, its prob in the evaporator, in the dash.....crummy job. best to take it to a shop that can evacuate the system properly and then re-charge after the leak has been found.

try to find the leak yourself to save on diag time, but remember this if the ac system is open to repair like replace an o-ring, the reciever/drier will need to be replaced, and if im not mistaken its an integral part of the condesner, which i doubt is cheap. Just a heads up incase they are looking for big bucks.

If you want to clean the D2 engine just power scrub the entire engine aty the car wash, with cold, non soapy water. If you have a little heavy oil, degrease that area only.

First thing you should do is unplug the compress so it doesn't continue to run while empty/no oil.
Because it has run low/empty, you should take it to a shop, get the repairs made then have them suck down the system to remove any moisture prior to refilling it, otherwise without doing this you can damage the system

So, stupid question maybe, but I was about to take mine in to get recharged. I have no cold air coming out at all, never have since I got it (about a month now). Can I just go to Autozone (or the like) and buy a can of R-134A and recharge myself? That would be awesome! Any reason I should not do it? This is for the 2001 w/. 67K...
Thanks!
Thanks!
