bottom line. TXV balances load for the compressor, and a OT flows same all the time.
if we had HUGE evaporators and condensers, and a decent accumulator, and pressure switches to cycle the compressor, it could work... I'd prefer to keep the txv and fix the issues with the dirty parts.
FYI. accumulator is to keep from flooding the compressor, receiver is to manage flow of condensed liquid into the txv so it always has perfect solid column of liquid.

Thanks for the explanation!

I just thought that this may be a good route for someone who has had a compressor failure. An OT coupled with a suction filter would make a "do over" more bearable. (I believe) Seems like there are stories of folks whose R4's ***** the bed and caused a lot of grief. This would at least allow servicing without going deep into the dash board.

After reading about the materials used in the internal parts of an R4 though, it may be "game over" no matter what you do. Seems that the block that the connecting rods are fixed to is made of sintered (or powdered) metal There's also a counter weight in there that's made of the same stuff This is mainly a cost cutting process that eliminates some machining processes. Had they used a different metal I don't think they would spew so much fine particulate through the system when parts failed...

Nothing wrong with sintered metal parts. But when they fail they can easily be pounded into dust which is bad for AC internals.
