hi all and congrats on a very helpfull looking site a couple of weeks ago i bought my first 4x4,a J reg 3.5 V8 efi disco for a bit of cheap muddy fun, yesterday me and some mates decided to take it up through kielder forrest, all was going well until i hit a puddle at around 25mph, not very deep probably only a couple of inches, caused a bit of a splash then there was a misfire and then nowt thought i had stalled it so i cranked it over.........nowt..........not even a cough, thought i may hav got the coil wet so i opened the bonnet and the coil was dry as a bone so i checked the dizzy and that was fine too shut the bonnet and tried it again, the thing only started straight up! is there somekind of cut off sensor on them to sense deep water and cuts the engine out to prevent hydraulicing? (excuse the spelling ) if there is is there anyway around it? am not exactly planning on trying to cross the channel but surely a big puddle shouldn't bother it? also a mate has just taken a 4.6 lump out of an R reg range rover and it looks very similar to the engine in my disco, would this be a straight swap for my little 3.5 or will it be more of a hassle than a gain?
