I had to replace the intake manifold gasket on a 99 Suburban. I unbolted the AC compressor and flipped it over towards the passenger side of the engine compartment, it was in an upside down position. After doing the engine work I drove the vehicle and shortly after, I think the compressor high side line blew and sprayed some oil out. It appears rubber line was kinked or something which caused the line to burst. Question is, did I do something wrong by flipping the AC compressor upside down? Could the oil in the compressor have accumulated and caused the line to pop? Thanks
Oil accumulation was NOT your issue ( heck- all OEM compressors mounted on engines at assembly plants are clear full of oil and started that way--
your kinking the crusty hose initiated the failure IMO.
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
