Whats happening is my scanner picked up a code saying the oil pressure switch is registering low oil pressure. No lights ever came on in the dash. However when I first start it up when its cold the engine makes a light rattling tapping noise for a minute then quietens down. As scared as I was I looked into this.I was using a fram oil filter then heard about them not having an anti drainback valve and replaced it with a NAPA Gold filter and put Penzoil 5/30W oil recommended. After a week or 2 I checked to see that code and its back.I then took out the pressure switch and put a handheld oil pressure gauge on it and read 40 to 45 PSI @ 1850 RPM.I called the dealer to find out the oil pressure reading and was told 60 PSI @1850 RPM.I looked at ARRC online database and said 15 PSI@1110 RPM.I am very confused and prepared to throw money at it but dont want to pull the engine. Im thinking oil pump, relief valve or bearings. The last thing I want to do is damage my engine as I have 5 more years to pay it off. Ive always changed the oil as soon as the maintenance light came on. One last note before I bought this car the previous owner had the intake manifold gasket replaced as it was leaking coolant a common problem with these engines not sure if water got into the crank case or how much the engine overheated. Any information or similar experiences or known problems, fixes would be helpfull. Thanks Mike?
