Low Pressure

Hi everyone, Will I did it. I bought a Toyota. 4Runner 1994. Very clean inside & out. Seems like low miles 146000. 2 days before Xmas. Of course it was for the lady of the house. But it seems that there is a little knock/noise from frt-mid ? not really from bottom/oil pan. I have noticed that the OEM dash oil gage shows hardly to no oil pressure , after a little warm up. And I'm quit sure it was reading a bit higher & not making that noise when we first got it. I seemed to notice about 3-4 days ago. But of course I recked the eng oil level. Which I cked just about every day or other day. Since new to me veh. I need to know what habits it may have. I changed the oil & filter 2 nights ago. No synthetic since I didn't know what was used in it. It still makes the noise. My ?'s are, Are there any quarks or known things that these 3.0 V6 Toyota motors have,do,etc. That might cause what to me seems abnormal low oil pressure or noise. Maybe someone can enlighten me about this veh. I looked into valve cover oil filler & oil is present while engine is running. As best as one could see. I don''t want to ruin it. Maybe I need to pull the oil pan & ck the oil pickup,or put rod bearings in it. But rod bearings doesn't sound like something that should need to be done this early in its life.
My wife likes it & she doesn't want me to get rid of it. Any & all thoughts appreciated. Chuck

Worn bearings can cause low oil pressure, since you dont know its history before you bought it theres no way to know how it was treated, no engine can last without regular oil changes, when the oil breaks down there isnt much protecting it. And I've met countless people who drive cars and drive them only they never have the oil changed, when the engine goes, they get rid of it or park it and get something else. I would find a place where I could check the direct oil pressure of the engine with a mechanical gauge, if it still reads low, its more than likely rebuild time.

We have done bearings in a few of those. Unusually worn with less miles than you have. Did this start after the first oil change. Sometimes less than honest sellers will load it up with heavy oil just to quiet it down and send it on its way. If you keep driving it with low presure you are going to hurt it. It could also be the pump. If I remember correctly the pan ws pretty easy to drop on the ones we did and the pump was in the pan like a chevy, dont hold me to that though. How low is the presure.
