I recently had to replace the engine and turbo in my MY13 Ford Ranger (2.2 4WD) due to an oil pump issue. Is this a common fault in the Rangers?

I recently had to replace the engine and turbo in my MY13 Ford Ranger (2.2 4WD). My mechanic said the problem was caused by lack of oil. He stated this was due to the earlier engine’s oil pump being a vane type instead of a normal geared type. Is this a common fault in the Rangers?

Your mechanic is switched on, and is right about some Rangers (both 2.2 and 3.2-litre variants) experiencing oil pump failures. It seems the variable displacement, vane-style pumps aren’t lasting as long as some owners are expecting them to, and there’s actually an aftermarket pump that reverts to the gear-style mechanism that some Ranger owners are retro-fitting. I’m not sure that it's at the stage where you’d call the fault commonplace, but it is not unknown. And, of course, if the pump does fail, you’ve only got a few seconds to switch the engine off before major internal damage ensues.

The bigger complaint among Ranger owners is that the standard vane-style pump allows only a ten-minute window in which to drain the oil out during a service and get the new oil in. If the mechanic takes longer than those ten minutes, the oil will drain out of the pump and, because of the design, the pump won’t self-prime when the engine is restarted, leading to it running without oil pressure. Again, that’s enough to cause terminal engine damage.
