Im only going by directions given from ES12A vendor, not to charge under vac. I pulled 30 in HG, let it sit for about 1 hr, it held pretty close to 30 in HG.

Then shut off pump and let system equalize back to 0, then charged with engine running from the low side. Took the compressor a min to come on but it did, and the 2 cans of ES-12A went in.

When you guys say system pressure should not exceed 50 psi on low side, is that idling? Mine will reach about 60 sometimes before the fans kick on and it lowers. If I give it some rpms, say 2500, the low side pressure drops to about 20 psi (dont know if thats normal).

I, too, think the issue is probably too much oil. Why else would the site glass be milky? When I pulled the vac, site glass was clear. As I recharged it got milky bubbles again and solid at full charge.

I know the internet is not the best place for this info, but this site is full of experts on this matter. I will listen and double check advice, but its good to hear from ppl on this forum.

Anyways...its blowing semi-cold at idle, and snowballs at speed. It seems like when Ive got air moving over the engine things work pretty well. I know this is indicative of the ES12A, but I was hoping for a little colder at idle.

How does one drain the oil on 87 300D ? And, do all those cans of ES12A contain oil too? If that the case, no wonder its got too much oil.
