Long, and sad, story but could have been much much worse.
My son drowned the Disco 2 in a flooded wadi filled with flash flood water. Thankfuly he and his girlfriend survived the ordeal but only thanks to a heroic rescue from the air and river bank.
A few hours later I manged to pull the drenched Disco out with the trusty Defender.
Following morning turned the engine by hand - not seized so good start. Emptied out the air box, pipes etc and fired the engine - started quickly and after running a little rough smothed out. Every time we reved up the engine cut and then would not start for a couple of minutes. Main computer out, opened, dried and cleaned and that was sorted.
Then found that the gear box was not working (auto) just 3rd and reverse. Took the gearbox computer out from under the seat and cleaned and dried that out and that sorted the gearbox out.
Now have to get all the mud and water out from the interior - water was upto the base of the front seats. And this is where I need your help - how can I best dry and clean out the interior which is full of fine silt and water ?
