I have a VDO oil pressure gauge in the center console gauge cluster. It is a mechanical gauge - oil line from the sending unit location on the top of the engine to the back of the gauge. I noticed this weekend the line near the gauge is full of air and only a little bit of oil in the line. Should I "bleed" the line somehow. If so how is that done?
Can I just open the line at the gauge and keep it higher than the sending unit area so the air will rise? Thanks in advance! |

I even use a accusump pressure gauge as my mech oil pressure gauge.
That gauge is supposed to read the air pressure on the dry side of the piston in the accusump, but it seems to work just fine reading the oil directly. I was even hoping that an air bubble would remain in the grease hose that connects it to the block. The air bubble IS compressible so it would act as a water-hammer (in this case oil-hammer) buffer and the gauge wont see as high of pressure spikes. |
