I have owned and worked on a lot of cars but I have never seen this happen. My wife came home yesterday and said her oil pressure guage was jumping up and down and the engine was making noise (1990 300SL - 102K mi). I started it up and could hear a couple of noisy lifters but the oil pressure was fine. I took it for a spin and about a block up the road the oil pressure suddenly dropped to zero and the red light came on. Then within 2 seconds it came back out to full pressure. It repeated this 3 times in a short drive so I parked it. By then the lifters had stopped making noise. The oil level is up. This is a new one on me. Has anyone had this happen on the 104 engine? No speculation please, this could be a very expensive problem. Thanks. Craig
