I just finished charging my A/C and fired it up. The compressor is making a strange noise. About once every second or two it makes a noise similar to lightly tapping a tin can with a screwdriver.
For the most part I followed the resently posted pictorial. I did all of the to-do’s like changing all of the seals, valve, dryer, and flushed the system. For the lube I used synthetic ester oil and charged it with what I estimate to be around 2.9lbs of R12.

The gauges are normal and the A/C works just fine.

Possible problem: I originally put the 4oz. of oil in the compressor and then 4oz, in the dryer like in the picture, but when your trying to connect the lines most of the oil pours out. I knew I lost most of the oil, so I filled the dryer with about 6 1/2ox of oil.
