I have never seen so many crazy statements from one person.

First you argue for changing out all the orings... which is fine ....

But then you claim that it is too much trouble to take the system apart enough to flush the items individually.

THAT IS WHEN YOU FLUSH THEM... WHEN YOU HAVE THEM APART TO INSTALL THE ORINGS...

Did you mean that a Condensor is easy to find a pinhole leak on ? Finding dye leakage in our well hidden Evaporators is impossible... Whereas detecting an R22 pinhole leak in the Evaporator is easy... because any leak is consolidated in the case as compared to trying to find it spread out in the engine compartment...

And... dye does not leak out of the top of breaks in the system as well as at the bottom..whereas R22 does not care if the hole is high or low...

But aside from that... dye has the potential for gumming up the TxValve.... so is to be avoided if possible.
