A picture is worth a thousand words

The regulator is only held in by that 2 bolt flange, which is separate from the regulator itself. The flange could be crooked if tightened down wrong. Is the regulator (brass part with the stem) level with the ground? It fits in a bore with an o-ring. I find it hard to be that crooked and not leak. Have you tried adjusting the regulator to see if it changes at all? Out to see if the oil pressure goes below 14psid, then in to see if you can get it higher? How many hours are on it or since last overhaul? Is your area prone to power outages?

Never been overhauled its an 08. Maybe it just the flange thats crooked.

I tighten the top bolt on the flange it looks better now

Found a service bulletin about debris getting stuck on the face of the pressure regulator and how to try to flush it.going to give it a try.

Yeah open that regulator all the way up and let it run a few minutes. Then crank it back down to where the stem was and see if there’s any change in the pressure.

That regulator is not seated correctly so the diaphram is not trapped correctly in the bottom of the recess it sits in . Obviously the regulator has been changed as its not painted green. So whoever changed it put it in crooked .
Dont pull the gas . Take the bolts out , remove the flange . If its in a vacuum the suction will hold the reg in . You should be able to turn the regulator freely in the hole with some resistance due to the O ring . If you cant turn it its crooked and jammed in the recess . It may suck a bit of air put the diaphram in the bottom will keep most of the air out . Unless whoever installed the reg butchered that too ??

Just replace the whole block and be done with it.... that can be done on the fly

With the loosey goosey US refrigerant regulations you can do anything “on the fly”
Just hold your breath and get er dun

Cannot be larger than 2 square inches if I remember correctly. If it's larger, it's gotta be recovered... at least in NYS.
I've done regulators on the fly. Usually use a boiler to bring it up close to zero. Never replaced an oil filter block. Wouldn't think there would be a reason to unless the seat is screwed up.

We have a reftec allvac recover machine should be able to recover the charge in about 4hrs.

4 hours? What size is the machine? Charge #?

Cvhf570 think it holds 8-900 lbs,

You ain't gonna get the charge out in 4 hours. It will take you that long to set it up and push the liquid out. Then at least that long to get the vapor.

I've done the whole block a couple of times with the machine just slightly below zero. With it off, there are only 4 small holes in the oil sump.

If you get your pro membership, I could describe the process for you, but not out here in the open.

I'll time i should be out there Wednesday. I didnt say anything about setup . I Maybe a little ambitious on the time but should be able to get it in s day i imagine.

I've had a question about recovery units like the one that OP posted a pic of.
If the chiller has air in it, how do you deal with it? Do you just burp it off the top of the recovery tank? Do you let the purge handle it after charging?
I only ask because our shop has more or less home made machines that has the ability purge as you recover. We also have a few large reclaimers that will distill 700# at a time... takes a while though.

I hook up our portable purge to the recovery tank when a chiller has a lot of air in it.

Well if this tells you anything about what think of the climate change fraud that has been perpetrated on the American public...…..I dig holes with my backhoe and fill them in just to burn the diesel fuel....LOL

Isolate the filter, the regulator can be removed, no need to pull refrigerant
