'Jerky' oil pressure gauge

[Mark Rinker]

High mile 2002 has good oil pressure, but gauge no longer operates in smooth, sweeping motion - rather, it jumps in 30-40# increments in either direction when climbing or dropping.

Replace OPS, or gauge? If the gauge, can the cluster be pulled from a wreck and maintain correct mileage - or would you replace only that gauge?

Put an ohm meter on the OPS output and monitor it. If it is bad, the meter should show the wild swings. If it has a smooth transition, replace the cluster. If you happen upon a used cluster, you can replace just the gage, but you aren't supposed to be able to. It will take some creative skill. You can send the cluster to a repair place (Robyn, I think, mentioned one that does this) and have the cluster repaired. Also, it may be a resistor on the gage causing the problem like older models, but I haven't looked into it, so it may not. If so, it would be a simple fix, just replace the resistor.
