CVHF910 losing oil

[Healey Nut]

Is the vent line solenoid valve the Trane OEM valve and which way does the flow arrow point on it .. To the suction cover or to the oil sump ??

Wow.....30 minutes and you lose the entire oil charge. You posted that the compressor was just rebuilt. On that I must ask if the bearing cap and gasket was replaced behind the Ball bearings. Thats the one with the six long threaded studs that go the the rear bearing web. The clearance on that bearing cap to the rotor shaft is extremely close and is often overlooked.
I did a CVHE1250 and screwed up not replacing it. Strangely it also took 25-30 min to dump all 7 gallons...

Arrow points to suction cover and it is oem. Also, i only replaced the gasket. May have been a mistake. It wont lose all 7 gls. in 30 minutes but you can clearly see oil level dropping pretty fast, so i just shut down. But, in the return line sight glass for the thrust bearings you can see a good return to the sump.

Update: Problem solved. It was the vent line valve not working. Sounded good but nothing going on inside. Pressurized machine and replaced valve and its running great. Thanks for the tip nuclrchiller
