I have a stock 2013 SHO with about 150,000 miles. I've had some issues with it, but always taken care of it. During a recent snow storm, my "low oil pressure" light came on as I was parking in a parking lot. After my car gets to temperature and when my car is at idle, the light comes on. The minute I accelerate, it goes off. I took it to the Ford dealership because this happened after I had some other work done to it (I've now had all the gaskets replaced twice). They replaced the oil pressure switch, which didn't solve the problem. They then diagnosed it and found that my oil pressure is dropping at idle. I spent 2k to have them remove the oil pan and inspect it. They found silicone and a piece of paper in the oil, which was caught by the pickup tube screen. They replaced oil pickup, resealed the oil gasket, replaced right intermediate shaft seal, and replaced left turbo return line. Get it out from the dealership, drive it about 90 miles, and light came back on when I was parking at a store. Basically once it is up to temperature, the light will come on when the car is at idle, such as at a stop light or parked and running. Otherwise, it drives great. No other issues with it at all. Dealership doesn't know what's wrong with it and Ford was of no help. They are telling me to drop 10k to replace the engine. I'm pretty disappointed because I've spent about 7k on repairs to the car in the last year or two, and just had new tires, rear shocks, and brakes done. Has anyone experienced anything like this before? Any thoughts on options?
