My car got drivin through a flood on Sat just gone and yes .....you guessed it ....the dredded hydrolic lock syndrome. Luckly the AA recovery guy listed and didnt try to start her again so no more damage could be done. (K&N 57i induction kit on)
When she had been transported back to me i set about getting the sparks out, disconecting the coils and fuel cut off, airpipe hoses and then cleanfilmed the coilpack connectors.
When all that was done and can throughly recommend this.......Get and old spray bottle top with a long pipe on it, insert that through the spark plug holes and pump/spray the water out...phew all done. then i cranked her over on the starter motor, sprayed some WD40 in to displace the water, left it for a few hours.
Put her back together and hey presto......she cranked over first time and she only sounds very slightly like an old sewing machine, so i got away lightly being as its always a 50/50 chance its totally fooked or not !
Now need to save up for a repair bill, if just valves then phew ! but then again , need new head bolts, head gasket, oil/filter, coolant, cam-belt kit including water pump etc.....could be a slight bent con-rod but can always drop the sump and change over, wont know until i can get the head off.
At the moment apart from sounding like a sewing machine ever so slightly she is tip top from her little swim. so remember all is not lost just because you got over 4ltrs of flood water in your engine
