Oil Pressure Problem

First post, hope someone can help.
I have a '93 3.4 V6 Firbird (I Know v6, not many here in the UK, take what you can get)
Start the car fine, while cool runs fine, once warmed up, when I accelerate
the oil pressure dips, not badly but enough to notice. No problems with performance or things going wrong. I would just like to know.
Cheers in advance

A drop in oil pressure after warm up is normal. What does the oil pressure read after warm up versus at start up?

Never trust the oil pressure gauge on the dash for "accuracy", because it isn't.
I agree with Ron on the reading of the gauge. Yes, it will dip a bit when the car is warmed up.
If you suspect an oil pressure problem, the engine's oil pressure should be checked with a mechanical gauge.
If the pressure meets the specs in the shop manual, then the oil pressure switch/sender is bad or the gauge is inaccurate.
If the oil pressure is not within the specs of the shop manual, internal engine failure/problems.

Worn rod bearings cause the type of oil pressure drop you are describing. It is not much of a problem unless it is below 20 lbs.

what
Worn Rod Barrings do NOT, I repeate NOT affect the readings of oil pressure at the sending unit. They only way they would is if the oil holes were blocked. That would rasie pressure, Not drop it. Charles

I don't know what you wrote is true or not. I can tell you that there were problems over the years with replacement cams and the clearances of the cam and bearings causing low oil pressures.

The Cam oiling is inline with the Valve train oil line. The oil flows from the cam area up thru the pushrods. Thus oiling the valves and springs. In GM pushrod engines the valve covers are used to redirect spraying oil to bath the valve train. From there it goes in to return galleys to the oil pan.
With the crank oil system the oil is returned right to the pan. The real low oil pressure engines are the Buick V8's. They will eat the gears out of the oil pump, mounted on the front of the block. Charles
