How much is the oil pressure supposed to be for a 6 cylinder

Hi Wanda,it's near your oil filter,here's a link from Autozone's repair guides on replacing it. Repair Guides Engine Mechanical Components Oil Pressure Sensor AutoZone com A deep well socket may work.Here's what the part look's like. http://www.autozone.com/external-engine/oil-pressure-switch/duralast-oil-pressure-switch/chevrolet/s10-p-u-4wd/2001/6-cylinders-w-4-3l-sfi/31135_709824_8450 Here's how to remove the distributor. http://www.autozone.com/repairinfo/repairguide/repairGuideContent.jsp?pageId=0996b43f803714e5 Good luck.

Here's a picture of your oil pressure switch,easy to replace,just disconnect electrical connector,get wrench and remove.It's located by oil filter,it's screwed into block. http://www.autozone.com/external-engine/oil-pressure-switch/duralast-oil-pressure-switch/chevrolet/malibu/2001/6-cylinders-j-3-1l-sfi-ohv/45356_652058_8537

Oil in the air filter is usually caused by blowby which is oil blowing past the cylinder rings, or a PCV valve that is not working correctly. The crankcase has too much pressure and oil is escaping out to the air filter where the crankcase is supposed to get fresh air from.
If the PCV valve and hose are ok, you may need another engine at some point. The rings and-or cylinders may have excessive wear.

1. Remove the exhaust manifold heat insulator.
   
2. Remove the fuel tube retainer bolt.
   

1. On 2wd models with the 6-cylinder engine:
   
   1. Remove the front right wheel.
      
   2. Remove the front gravel shield.
      
   3. Remove the exhaust manifold heat insulator.
      
   4. Remove the exhaust manifold.
      
   5. Detach the oil pressure switch connector.
      
2. Unfasten the remaining electrical connections at the starter solenoid.
   
3. Remove the two nuts holding the starter to the bell housing, then pull the starter toward the front of the vehicle and out.
   

To install:

1. Insert the starter into the bell housing, being sure that the starter drive is not jammed against the flywheel.
   
2. Tighten the attaching nuts and secure all electrical connections to the starter assembly.
   
3. Install all remaining components in reverse order of removal.
   
4. Reconnect the battery cables. If applicable, refill and check the oil level. Check the starter assembly for proper operation.

Starter removal on 2WD-6-cylinder engine

Starter removal on 4WD-6-cylinder engine

On 4wd models with the 6-cylinder engine:

Remove the front gravel shield.

1. Detach the oil pressure switch connector.
   
2. Drain the engine oil and remove the oil filter.
   

On 4 cylinder engines: The oil pressure sending unit is located in the rear of the block near the oil filter housing
On 6 cylinder engines: Sending unit is located near the oil filter housing behind the air conditioning compressor, on the front side of the block

jeep is known to have faulty oil pressure switches,check that first,if it's good then you have a weak oil pump.

Starter - REMOVAL & INSTALLATION
(see Figures 1 and 2)

1. Disconnect the negative battery cable at the battery, then disconnect the positive battery cable at the starter.

   1. Remove the front gravel shield.
   2. Detach the oil pressure switch connector.
   3. Drain the engine oil and remove the oil filter.

CAUTION The EPA warns that prolonged contact with used engine oil may cause a number of skin disorders, including cancer! You should make every effort to minimize your exposure to used engine oil. Protective gloves should be worn when changing the oil. Wash your hands and any other exposed skin areas as soon as possible after exposure to used engine oil. Soap and water, or waterless hand cleaner should be used.

Hope this help (remember rated this).

the oil sending unit that screws in the block beside the oil filter may be faulty,
the worst thing would be the oil pump its self the regulator valve on it
