On my drive to Raleigh last night I noticed a few things that I normaly wouldn't on my 2 mile stop and go trip to work each day. On flat ground, cruise set at 70, my oil pressure will fluctuate between the "O" in Norm down to where the check guage light will come on. The total time for a cycle is about 7 to 10 minutes between the 30 second drop and rise in pressure. I just changed the oil before the trip. The oil pressure sending unit was replaced just over two years ago.
I did just switch from synthetic to organic b/c I am going to be tearing the motor out at my dads garage and there was no need to spen 40 bux on an oil change that needed to go 130 miles. Could that change have somthing to do with it?
Also, what causes the studder and almost stalling of an engine when you come to a stoplight after highway driving? I know old cars without computers and stuff, and normally that is caused by bad timing. Is that fundimentaly still the case with my SC? I have seen timing chains strech on older V8's with alot of torque, has anyone seen this happen to a stock SC? At idle the symptoms are that of a bad valve or two in which you get a random bumping noise inside the car car caused by the exhaust valve not closing when the piston drops resulting in the drawing of exhaust into the cylinder. What I don't understand is why it comes and goes.
Any help you guys can provide before I start dismantling the motor will be greatly appreciated.
