i have a 1995 chevy caprice with the 350 and when its coil the oil pressure is good, but when it warms up the oil pressure drops so much it makes the "check gauge" light come on. the car leaks ALOt of oil when its hot, it leaks from the front part of the engine. the car has 147k miles, i only put on about 30 miles since i had it(i would not prefer to drive it with it like this). the engine for the most part is in good condition but i dont like oil spots. would thicker oil do the trick or some other remedy. cant afford to take the engine out to check the pump, unless there is a way to test it still in the car. need answers i give 10 points
