Let's see I got 60 hits and no advice or remedies concerning my car.
Does ANYONE HAVE ANY KNOWLEDGE concerning MY oil pressure ISSUES?

please help me out

 

It might help if you actually list the problem or symptoms you are experiencing...

 

Oil pressure concerns
I have a 99- 996, my oil pressure fluctuates going around curves( not at really high speed) drops in between 3 and 4.
When the car is cold it sits at 5 until warm. Idles around 2.
Oil sending unit replaced, oil pump replaced and oil changed.
Sometimes at higher steady speeds it will fluctuate between , slighly above 4 and slighly below 4 rapidly.
Car runs and sounds great.

Any thoughts. Dealer said Porsche recommends replacing engine.

 

If the car is warm and you have no load, it is normal for the pressure to drop to 2 at idle. If you are removing load while going around corners, 3 or 4 doesn't sounds like a problem either. I would not consider a minor flicker in the the needle to be an oil pump problem without further confirmation - I would expect that to be more related to the gauge itself. An oil pressure problem would not affect how the car runs (until it's too late), but the symptoms you have described here do not sound like cause for concern.

 

Similar to Slider, almost every unusual oil problem I have ever seen was traced to something other than the pump and genuine pressure.

Ideally, you'd get a mechanical pressure gauge to compare against the electrical gauge. But since your problems happen at speed in corners -- that seems hard.

Since you've replaced the sender, maybe the cheapest/easiest test would be to run wires from the sender to a spare gauge or test meter in the cabin and see if it fluctuates at that same times your dash gauge does. You don't care if the needles are on the same scale. You just want to see if the test unit drops at the same time your dash indicator does.

 

Thanks to you both for your advice and suggestions .
Much appreciated

 

a few things.... if your temp needle is pointing perfectly strait up then you will have decent oil pressure... if your temps are hotter and your needle is say slightly to the right of the zero then the oil is thinner as a result of heat and you will have less oil pressure...

curious... where are you getting between 3-4 bar ? on the street or on the track.... its normal for hard cornering to generate 3.5 bar on the track.... but check your operating temps... oil pressure is directly related to engine temps...
