And remember, leaks are found with the system under pressure. You will have to find it with a leak tester or with soapy water or with the trace of oil it leavs behind.

If this sytem is under a good 29" vacuum, holding for 20min. or so, you will know if it leaks or not. If it leaks the vacuum will be lost to 26-24"
