I have a interesting problem. On my ford windstar 2000, the lines that go into the accumulator blow out when the engine is off and after the car has been driven for a while. Last time it happened it was standing in the drive way for about 10-15 min after it has been driven. When I say that they are blown out, I mean the stud is broken in half but the threading is intact (nut is still on the broken off part). This has happened three times already. The mechanics shop assures me that the pressure reading are correct on both low and high sides (40psi on low side and 280-320psi on high side). The system has a brand new accumulator, new compressor and new oriffice valve. What's interesting to me is that these accumulator blow outs occur only when the car is turned off. I assume this happens when pressure redistributes? Is there a valve that would protect the accumulator or low side from high pressure side when the car is turned off? I just ordered some gauges so I'll be able to give more details on pressures. Any help or pointers would be most appreciated. Thanks in advance.
