Best Way to Flush AC system?

[Philoprof]

As I mentioned in another thread, I just changed the compressor on my 380sl. But, afterwards, when I evacuated the system, I turned the vacuum pump off and left the ports in the manifold gauge open. So, app. 100cc of oil from the Mastercool vacuum pump got sucked into the system, because the pump didn't have a valve to prevent that from happening.

Anyway, as I now have to take the system apart, and flush it, I was wondering if I also have to flush the evaporator coil which, if I'm not mistaken, requires removing the expansion valve first.

So, I was also wondering if anybody has ever done this on a 107 and, if so, how difficult it was.

Thanks in advance.
