Water in EFI fuel system

Q. Can you help us with some practical advice regarding what to do when we’re out on the tracks? This issue came up the other day when a buddy of mine swamped his three week old BT50. He launched into what looked like a small puddle without checking the depth, and ended up nose-down, windscreen-deep in dirty, stinking, muddy water. The vehicle stalled so we towed it out and back to the road, where it was trucked back to Mazda and is currently being worked on.
My question is this – what can you do to the new EFI, high-pressure fuel systems to get water out of the cylinders? It doesn’t look anywhere near as simple as the older style systems where you just pulled the injectors out and cranked it over on the starter until the cylinders were dry. Can anything be done on the side of the track, or is a tow truck home the only option?

A.It’s a very sad thing to have a vehicle swamped because if it’s an insurance claim it will be ‘written off’ without question once the words ‘water’ is involved. On an old Toyota Hilux 3L engine you would have just taken out the glow plugs and ‘cranked’ the engine for about 30 seconds to blow out most of the moisture/water. But on a modern multi-valve CRD engine it may be a different story. If you can see glow-plugs then use the old principle. If you can’t then you will need to remove the rocker cover and look. Most likely you will need to carefully remove injectors, mark them 1,2,3,4 and be extremely clean with anything you do. To be extra safe confirm what you are doing by calling me at Berrima.
