Rick, Thanks!. I think that amount must be right. He told me that I would need 11 oz of oil. He said add to compressor and put the rest in the condenser,etc. So you must be right. On the expansion valve here is what was said: These types of valves, although efficient, have some disadvantages over orifice tube systems. Like orifice tubes these valves can become clogged with debris, but also have small moving parts that may stick and malfunction due to corrosion. If anyone wants the vacuum down instructions he gave me, email me or I can post it on the list. His instructions were very detail and different from how I have vacuum down in the past. I have always put the vacuum unit on the system for about two hours and then charged, but this is not how he instructed me. ON Harbor Freight Tools site, they have an Air Vacuum Pump which only sells for $10.00. This seems too cheap. Electric units usually sell for 150.00-350.00. Here is the page on Harbor: http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=3952 What do you guys think?? Is this junk?? What do I need to look for in a vacuum unit. I just want one good enough to do my cars only. I am not wanting to go into the a/c business.
