I have a 1987 Dodge Ram D-150 (106,500) that may be on the front end of trouble. I've only noticed it recently (since it is warmer now), but the oil pressure seems to drop when stopped at a light (I can watch it tick lower-line by line, and lower the longer I sit). If I rev the engine, the guage indicator goes up as if it may be getting the necessary pressure.
When at highway speed the guage reads perfectly fine in the middle. I recently changed the oil and didn't notice any metal shavings, or anything else abnormal. I'm using 10/30 oil and haven't noticed any noise when the pressure drops (but will keep an ear out for it).
I don't want to go and start changing parts without some sense of direction. Any ideas?
have the same problem?
