Hi All,
I know it is not generally a good idea to drain oil from the receiver but for some reason we have a couple of receivers (on the same system) that are getting a lot of oil build up.
We drain the LPR and the Intercooler regularly but we're not getting the oil out of the system.
I was thinking of running a charging hose from the bottom of the receiver to the intercooler and dumping the oil into the intercooler where we could more safely drain it out.
I have, long ago, drained directly from the receiver but I didn't like it. We may have pumped the receiver down before we did that. I don't really remember.
I'm interested in any thoughts on this.
Also, I'm thinking that maybe the reason we are seeing so much oil is due to our reduced head pressure.
While I like the head to run as low as possible it may be that the piping isn't conducive for the low head.
We installed a new condenser about 8 months ago and have since been running a much lower head pressure, about 120 where before that we were probably running at about 140-165.
Just a theory.
Thanks in advance for any thoughts on these topics.

Peter
