The day before the wedding it had fuel in the coolant, the day after the wedding it had a toasted engine. I have never looked into it before but a workmate also had an engine failure in a Jackaroo. A bit of hunting today shows up that failures around the inejectors can also result in fuel going into the oil and if it gets bad enough to raise the oil level far enough to start putting oil/diesel mix through the breathers into the inlet then the engine can become a runaway! it wont even stop when the fuel flow stops if you switch it off. I suspect from the descriptions I got from both Jackaroo failures I know of that it is what happened to both of them.
About the only way to stop them is to crush an inlet pipe and starve it for air! Coincidentally I saw a post on facebook from a mate about doing this very recently to a Rodeo (With possibly the same 4jx1 engine) he came across revving its brains out in the middle of an intersection. I don't know how keen I would be to open the bonnet and crush an inlet pipe on a valve bouncing diesel!
A bit scary and will keep me watching the oil level on my Pathfinder although the fuel sytem works differently on that and I don't think it can do the same thing as easily. It also has a shutdown butterfly that starves the engine for air on switchoff, hopefully that actually stays shut until the engine stops completely.

Some of the early hilux 2.2 diesels would do this once they got a little worn out. Fuel would make its way into the sump and when it got high enough the motor would go into two stroke mode and rev it box off until it was stopped or blew up. Toyota's remedy was to change the oil every 5000km to prevent build up. We had a couple of them on site that would do it with great regularity......scares the @#$% out of you the first time iot happens.
