yes I am digging this thread up from the grave.


3 years ago I had a breakdown as the oil pressure switch had a catastrophic failure and was spewing oil onto a hot exhaust (at highway speeds). At this time I had a local shop put in a new pressure switch, pan (rusty) and pick up. Since this my pressure as been around 60 (prior was 40). I drove it with no care and dismissed this to a properly working pressure switch. Recently It jumped to 80 with the occasional drop to 70. It is not pegged at max but vary close.



I have 125k, no leaks, original PCV with broken breather hose and some build up (nothing in airbox). I do also get code 51 but don't think my o2 sensor is related.



Thanks

The gauge connectors in the cluster can lead to wonky readings.
Did you try a different oil pressure sender? Or verify with an analog capillary gauge?

I have not done either.
