Searching for an Oil Pressure Gauge

[dwhitaker]

Hi, I hope all Chim owners are enjoying the brill weather for a hoon?

I have come to the conclusion my oil pressure gauge is faulty. It reads very high, and even 35psi ignition on/engine off. So I am searching for a white Caermont gauge with brushed ally bezel to replace it. Hen's teeth are more common.

I have replaced the OPS, no change.

I have had the gauge on the bench, and with a battery and a bunch of resistors have plotted the gauges response to various resistance values. It should be responding to 240 to 33 ohm VDO standard (though the TVR OPS is typically 300 at 0psi, its pretty close).

Here is a chart of the measurements. Any advice, or pointers on where to get one appreciated. All the best.

Caerbont are Ford / Smiths calibrated AFIK, VDO calibration is for the early ETB instruments.

Thanks for commenting spend. Irresprcitve of Ford/VDO/Smith (Smith indeed own Caermont) I mine is still faulty, and needs replacing. 1997 Chim, white dials, cant find a source. Breakers?

Breakers or Ebab
Get ready for some thing getting well and truly slapped
Or get it repaired ?

[dwhitaker]

Its a sealed unit, or I would give it a go. Is there a specialist tvr breaker?

[jojackson4]

Yes there is 2/3/4 of them

Go to eBab and search tvr
