Default Hydrolock Scare

Not sure if this is the right place to put this if not mods please move.

Story:
A couple weeks back we had a really bad downpour and I got stuck having to go through a really big puddle (puddle ending up being a mini pond ). Car died out but I was able to get it back started. Check engine light was on and cruise control was flashing. Got the car to dry land and left it over night. The next day I checked the car out and started it up. Started fine, but whiteish smoke was coming out the exhuast. I drove it to Perry Subaru and they checked it out. They found no water in the oil but when they removed the spark plugs they found water in the engine. They cleared it, test drove it and it drove fine.

Question:
Is there anything that I should be concerned about? Is is possible that something got bent that they couldnt see? Should I get a compression test done?

C/N: Drove car through puddle, got water in motor, got water out of motor, runs fine, ibparanoia.

take it for a good roadtrip to get everything burnt out, change your oil, and never think about it again. if you actually did hydrolock you wouldn't be on here asking if you did damage, you would KNOW there was a problem by the pieces laying on the garage floor.

does the transmission have vents on it? you might want to change the gear oil and rear diff oil just in case water got in there. also your cats in the exhaust could be wet but I don't know if that does anything bad because water is a byproduct of gasoline combustion anyway

Ya, I would change out the oil, tranny oil, and use the whole tank of gas to be on the safe side. The people that took the water out most likely didn't get 100% of it out, and although the oil reservoirs are made to be waterproofed, you just never know sometimes. Idk how high the water level was that you drove through but I would also watch out for appearing rust spots. Especially if you made any mods that had steel in them.

Is it possible for water to get in the transmission though?

Not sure about the transmission (most of the 5spds don't have a breather, iirc, so unless it got up over the dipstick tube, it's probably fine) - the rear differential, on the other hand, does have a breather - if the water got up over that, then there could be water in there. it'd have to be pretty deep, though...

Changing the gear oil in the rear differential is easier than changing the oil, imho - undo the fill plug (do that first - if you can't get that out, you really don't want to open the drain), open the drain plug, put in the drain plug, add 0.8qts or so of gear oil, put in the fill plug, and you are good to go.

It's hard to say how much water is in there, if any, without opening it up... that being said, I'm sure you'd be just fine waiting a week.
