Enyone experienced oil problems with this compressor. Have just got delivered 2 of these. And when starting they run, and sound normal. But after 10 min they start squeeking from the cylinders. Have measured the oil pressure and everything seems ok. Have also disassembly the oil pump, the back bearing and blowing nitrogen everything + the shaft..Everything seems ok. But the oil pressure drops suddenly, and there is not running eny oil thrugh the shaft.
