I have aftermarket pillar gauges fitted and recently there has been a load of water/liquid coming from the oil pressure gauge.

 

Now now my initial thoughts are leaky roof, so the water is running down the pillar into the gauge units. But I noticed the water is a bit dirty earlier on so I thought I would ask the question how the oil pressure gauge works? Is it electronic (i.e from a sensor) or is it hydraulic (hence why I'm getting pumped a load of water into the cabin).

 

This is what I have:-

 

Blocked drain in the pillar matey, i had the same problem. Get some wire down there with some plastic glued on the end and will be fine.

Al.

Is the drain about halfway down the pillar then as this would explain why its resting near the oil pressure gauge?

The oil pressure gauge is electronic, so takes a wire feed, the only gauge you have there with a pipe is the boost, but that will be air and not water, so you are more likely to have a

leak from the targa drain pipe, which runs down the pillar.
