No there is not. Just a open oil gallery hole.
Did you remove oil sending unit and install a oil pressure gauge in it's place and read it so you can rule out the gauge in the dash and sending unit ? If not, then do it. Then if you don't have oil pressure. Remove the oil pan and check the oil pump pick-up screen to see if it is stoped up, if it is replace oil pump and screen. If it's not then replace oil pump and screen anyway.
check the oil pressure snding unit first then check the pressure gage if both are good you need to replace oil pump Oil pumps in buick 3800,s do not go bad. Replace sending unit or the oil pump pickup screen is clogged.

It would get dots on the screen if it had not been cleaned properly.
it breaks your screen
Evaluate the condition of the screen and make a decision. Since the vehicle is 9 years old, why not just go ahead and replace it while you've got the pan dropped.
Worn main or rod bearings if pressure drops at idle. Faulty gauge or sending unit. Faulty oil pump or clogged pick up screen. Piece of crap car. Etc.
You can fix Wii Black screen without sending it into Nintendo by pulling out the plugs at the back, and re inserting them.
THe viewsonic screen should be cleaned as needed,this time will vary on conditions.

Check oil level Replace oil sending unit Engine internals worn due to mileage (as you raise the engine rpms oil pressure will raise) Weak oil pump? Clogged oil screen?
An iPad screen protector can really be a good thing for you to have, but it may be more dangerous than helpful if it is broken. A cracked protector can bend down and scratch the screen when pressure is applied to it. This could happen if it is in your bag, for instance, with your books. As soon as it breaks, you need to replace it to prevent any further damage to your iPad.
