i went 4x4ing today and managed to drown the disco

inside and out. without thinking i restarted it twice after it conked out in the water. only a few seconds later did i realise why it conked out...
resigned to becoming a garages highest paying customeri wasnt too fussed at what happened from here on. we pulled the car out of the water hole opened the bonnet and found a soaked air filter and water in the airbox and intake areas. did a quick clean up, fitted the old air filter(lucky).
i had a look at where the glow plugs were and decided that i was already 'peeved' enough that i would just chance it.(i dont recommened this action) after several on/off cranks to hopefully clear out any left over water the car idled smoothly. white smoke was pouring out of the exhaust, along with black water(the exhaust was submerged too and had water inside it).
after a few minutes the smoke/steam eased up and i dared to look at the dipstick and oil filler cap...
a tiny amount of water was evident on the dipstick, filler cap too.
pretty well resigned to the fact that i was going to be up for lots of $$ to fix either head gasket, bent somethings, etc. i decided to just drive home slowly(about 40kms) the trans was in limp mode(i've just found out that the EAT ECU is under the passenger seat and so, got soaked) but wasnt flashing the m&s lights??? part way home the 'S' light came on, but nothing changed in the operation. then just before i got home, the 'S' light went out. trans still i nlimp mode. I'm about to remove the trans ecu and dry it out. should be ok i hope.
i had my nanocom and kept my eye on the water temp the whole way home. nothing abnormal happened. at first driving home the car kept on putting out a thin,whitish smoke which i assumed was head gasket related since the car had been running for over 30mins since the drowning. after 1/2 way there was no more smoke. i figured either no more oil, or no more coolant.
well when we got home, i went and checked all the external things i could check. coolant, oil, coolant level, oil level, filler cap removed and no choofing. it sounded and performed(trans aside) like always. no coolant had leaked, there was no more trace of water in the oil(can it boil off?) and the oil level was ok.
i think i have used up my yearly quota of good luck. but more than anything i'm very, very impressed that a 206000km old engine didn't die after my lazy de-flooding procedure. and it doesnt seem any worse off for the experience.
are there 'breather' holes in the air box that could have caused the drowning? thee was no sign of the snorkel leaking.
