Cold engine , hot, both ,at idle or only at 3000 RPM up.
we cant guess any of that. and matters. does does:
NO numbers, ,try the PSI, numbers. post them
do you need the spec, we have it from the real FSM book.
use a real gauge, to measure it , not the toys in the cluster.
no oil weight stated API 50w?
pump relief valve stuck closed.
not using real shop gauges to see TRUTH.
Wrong oil; bad bypass relief valve; bad gauge.
SOURCE: have a 95 jeep wrangler. 4 cyl engine. Oil
Oil pressure switch short on a 2.5 it is on the passenger side on the back of the engine block if the is oil on the switch replace it 99.9% of the time this is the problem cheep to replace and not hard to do.
SOURCE: oil pressure excessively high
There are a few things to cause the oil pressure to change.
The first, and easiest to check, is your oil filter. Some filters have a bypass valve, when did you last have engine serviced ?
Another part is the oil pressure sender itself. It may be shorting or going bad.
Please check those out and let me know.
