low oil pressure after engine warm
Hi, I own a 1989 chevrolet s10 tahoe blazer 4wd. My oil pressure gage reports a low lever oil pressure after the engine is warm. What could cause this ?

oh. ouch.Do you have the 4.3 or 2.8?
First thing to do is,check oil (duh,but u would be surprised on who doesnt)
Get a mechanical gauge. Replace the oil sending sensor with it and see what the real pressure is. Sometimes the gauge or sensor can go bad resulting in this. If pressure is still 0,its time to replace the engine. You could try the oil pump,but chances are the engines just tired.

I have the 2.8, from April 1995, nice truck !! I noted that sometimes, when the spark plugs or the spark plugs wires are bad, the oil pressure goes down after engine warm, given to a poor electricity condition inside the engine. But now I checked with a multimeter the spark plugs and wires and are ok.

he is correct. the electrical (spark) has nothing to do with the sending unit as long as your alternator and battery is good.
sounds like you need a new engine. Test pressure using a mechanical gauge first.
