OK, I am stumped. I was fixed a leaky O-ring in the AC on my LC 100. I pulled vacuum on my AC system with a vac pump.
The vac pump failed, and all the dinosaur oil from the vac pump sump got sucked into my AC from the (good) vacuum. I estimate it was a couple ounces.
So I took all the lines apart, cleaned them out, drained the sump of the compressor, filled it with the right amount of PAG 46 oil, new drier, and buttoned it all up. Put in 39 oz. of Freon, but noticed the low side pressures were very high (60psi). Figured the bad oil mixed with the PAG46 and was gooping up the expansion valve. Pulled the evap core, replaced core, expansion valve, drier bag.
So pulled another vacuum, and... STILL low side is too high after I put 39oz. in, I was hitting 60psi low side (150psi high, but I measured on a half a charge. I'll measure on the full charge.)
I'm kind of stuck as to where to go from here. Anyone have any ideas???
