i have a 1994 chevy k1500 with a 350/ 4l60e. motor has about 75k miles and new heads with around 8k miles. my truck has low oil pressure and i can't quiet seem to figure it out. i'm pretty mechanicly inclined and know the truck pretty well inside out, i changed the oil and filter less than a week ago and put a mechanical gauge on it it ran good high 40 psi at idle for a few days then the past two days it'll run around 40 cold then after it warms up from driving it it'll almost drop down to 0 in gear at idle. i'm not sure what the problem could be i even went from using 5-40w oil to 10-40. any help?
