I have a question about oil pressure
I have a 99 Taurus Wagon with the 24 V Duratec engine. I have noticed recently that after driving at highway speeds for a while, when i get off the highway and stop for traffic signals, etc., my oil light will flash or come on. when I accelerate, it goes back out. Most recently, I drove at moderately higher speeds (75mph), and the light came on when I stopped and ther valve train sounded noisy. When i increased engine speed the noise went away and engine sounded normal. I stopped to check oil level, which was fine after letting the car sit for a few minutes. Upon restarting, no oil light, no noises. I am wondering if the oil passages in the engine may be restricted, or if the pickup screen is clogged. Under normal driving, no issues.
