If this was 5 years ago, this would be an easy answer. Replace the vehicle. But unfortunately, things really changed in the vehicle market since then. The vehicle is a 2009 Ford E-150 Cargo Van 4.6 v8 with 246,000 miles on it. A few years ago, an oil leak developed and got it checked out thinking it would be a small job. Unfortunately, it turned out that the oil is leaking out the head gasket. Big job. So we decided we could live with till we get the vehicle replaced. At the same time the supply chain only worsened. But now here we are and I am feed up with the oil leak. So hear the question? With the mileage on the vehicle, shall I just fix the leak? You figure that engine is stone reliable and would last me another 250,000 miles or it is that many miles do an engine swap or rebuild?
