The pickup tube is a bad design in these engines, I have fixed several with the same problem, you can weld on a GM screen move it 1/4 of a inch away from the pan or add 1 inch to the bottom of the pan, (use a high volume pump) the problem is the screen is too close and too small and will pick up any sludge off the bottom. also it's great to make a access plate on the bottom of the pan using a Volkswagen Bug oil cover plate, it can be removed with bolts after a oil drain to clean the screen without the hassle of removing the whole oil pan by lifting the engine on these trucks. Good Luck

SOURCE: Low Oil Pressure and rough idle
Please understand, all I can offer you are suggestions, since I don't have access to hands on testing. You might first change oil and filter.
If going by the oil pressure guage, low oil pressure can mean worn crankshaft bearings, as the clearance between bearings and crankshaft is what determines oil pressure.
Of course a worn oil pump can cause the same problem.
You might want to connect an external oil pressure guage to the engine to verify the pressure reading.
The rough running at this point would be hard to pin poit.
Because I do not know the extent of the rust, I can suggest that you consider having it undercoated.
Again, I can only make suggestion because you need an absoluate diagnosis.

First have your oil level checked and make sure that it is at the right level. If not that's your problem, if your level is good you may have a bad oil pressure switch. This can be checked by using a oil pressure guage. If switch is bad replace and solve the problem. However if your vehicle has alot of wear and tear on he engine and you were using 20w-50 oil and it was replaced with 5w-30 that oil may be too "light" for the vehicle and you would get a low oil pressure reading. Good Luck

Hi! The problem you are outlining is very similar to the Rover V8 (Buick engine). We Brit's are used to the low oil pressure when warm. I presume a complete oil change engine flushed with new replacement filter has been carried out? Maybe a top quality synthetic oil with additive may help. You may take it a little further and replace the oil pump with an after market performance up rated one. If you really are worried about low oil pressure damage whilst in low rev's try Molybnenum Disulphide an oil additive which really reduces friction metal to metal wear particulary in the situation you are describing.
That's the best I can suggest at this moment.
Good Luck! and Happy New Year!
