I own a 02 Intrepid SE, 2.7 with 164,000 miles. Oil light came on for the first time a couple of weeks ago. Dropped the oil pan, which was a simple job. Just as I suspected, sludge and carbon had blocked the pick-up screen. What I hadn't expected was so much of it. The inside wall's of the oil pan were coated with a good 1/4 inch of the stuff. So I cleaned the pan and the windage tray and the pick-up tube and screen and re-installed all parts. Replaced the oil using Castrol High Mileage Oil and a PH16 Fram Oil filter. I will run the engine for 500 miles and replace the filter and oil as described above. Now for the " FIX "! If you will look at the way the cranckcase is ventilated on this engine you will notice that both valve cover vent hoses are connected to the suction side of the engine. Pass side is connected to the air intake hose, creating a vacuum to pull air from the crankase. The driver side is connected to the throttle body, also pulling a vacuum on the crankcase, this set-up puts the crankcase under a sealed vacuum. There is no place for the engine to pull outside air, to let the engine breath. My solution is to remove the pass. side hose and block the opening at the intake hose and install a breather cap at the valve cover the way the older engines had it. This should let the engine breath the way it was done for many years. Only time will tell if this plan will fix the problem with sludge build-up. The way I see it, we got to try something and this idea might just do it.
