134a in a 90q system?

[Richard J. Andrews]

anyone done this, seeing as i wasted my r12 in a junk york compressor,
i've got a new compessor of a 90 that was used for 20 seconds (literally)
there was system blockage and dad said to heck with it..
so seeing as i've got r-12 oil all in the system should i just stick with that?
i've done some research and looks like 134a doesn't like the r-12 oil.
is there an easy way to flush this or not really?
i may just go back to the r-12.

but hopefully after the custom hoses, and the new drier, evaporator and
expansion valve and a 90 compressor
i'll have some kickin' a/c. sure would be nice as i am in texas and
planning a drive to cali (desert driving).

oh did i mention that the york compressors suck IMO?

any thoughts?

TIA!
