AC troubleshooting

If your high side pressure shot up to 450 immediately then you got air in there man.

Whats the liquid line feel like when this happens? The line that feeds the orifice.

Is it scortching hot or cool with that head pressure?
If its cool then you 100% have air in there.

Sorry sorry...just reread..

OK...SOOOOO....

your high side tap is right before the orifice.

If thats is getting scorching hot as well, then you got issues with your condenser coil.

Honestly, your compressor may be taking a crap on you. Generally when compressors start going bad theyll shed metallic material and internally plug up the condenser coil.

Feel your condenser. Make sure your fans are ON.
IF That condenser is hot you're not removing heat.

The line that the High pressure side is on is scorching hot. I believe that is the the feed to the orifice.

Thank you for the help.

Whoops didn't see your second post.

Ok so my plan will be to grab a condenser, dryer and orifice tube on my way home. Install the new orifice tube vacuum the system and add some coolant. Check temp of condenser and then go from there. If condenser is clogged should I just bite the bullet and buy a compressor as well?

Or plan B I can just order a new compressor, orifice tube, condenser and drier then rebuild basically the entire system. I can get it all delivered by Friday for 254 Amazon dollars. What r134 do you suggest?

Honestly thats not a bad option.
Could do that. Just ensure everything is 100% leak free. Thats your main goal and you'll be good.

Yes if that condenser is hot and isnt lowering your head pressure, and you KNOW....that you're leak free and have no air in the system...

Then yes that condenser internally is getting plugged in areas most likely due to your compressor.
Thats the only thing that will plug them up internally.

Get a garden hose on it while its running. Seee what happesn

Since I found the parts decently cheap and all AC-Delco I'm just gonna do an overhaul.

What R134 do you suggest? This is on prime and has good reviews. https://www.amazon.com/gp/product/B07QKM49ZG/ref=ox_sc_act_title_2?smid=A1OYBDZNBHG2RG&psc=1

This oil looks decent as well https://www.amazon.com/gp/product/B00CFQQSJY/ref=crt_ewc_title_dp_1?ie=UTF8&psc=1&smid=ATVPDKIKX0DER

134a with no additives is the best.
