I have a fleet of Taurus and Mystique vehicles. Oil dye and a black light are the best way to inspect these, drive it a few miles, but be careful to study the dye carefully and make sure it has fresh leaked oil with it to confirm a leak. There are many components including dust that can make you think there is a leak when there is not. What I have seen on ...

It would not be the head or the head gasket for two reasons. First, the head gasket sits below the head and the exhaust. There's no way for it to be getting onto the exhaust manifolds. Secondly, there's no pressurized oil which goes through the head. All oil which gets to the top of the head comes through the push rods in the valve train. I'd suggest ...

There's a very straightforward answer to this question: Water has a much, much higher capability to transfer heat than oil. Even if you were able to overcome the safety and design issues brought up in other answers, you'd still have to overcome the fact that water has a huge performance advantage at transferring heat compared to other common fluids (...

Water has the nice property that it boils at a fairly low temperature, so the vapour pressure rises quickly with temperature and it is easy to design fail-safe over-pressure protection (a simple spring-loaded filling cap). Also, water is not flammable. Oil does not have those nice properties, and a cooling system failure which released high pressure, high ...

Oil has been used as a heat transfer fluid in many applications (especially high temperature ones) but in engines the higher viscosity will require more pumping power, which means more driving power from the belt and so more power from the engine. Then there are the issues of cost... and, of course, issues with replacing fluid if you are far from an auto ...
