Drove through a big puddle of water?? Should I worry about it?

So itís been raining heavily in my area with some parts of the streets flooding.I was driving home from a mechanic in my 6mt sedan and right when Iím about to hit the front of my home I get faced with a huge puddle.I tried to reverse it and take the alley behind me to go around instead but as soon as I go in reverse I see traffic forming up behind me and then I realized I was screwed and I had to drive over the puddle.the puddle was high Enough to hit the Infiniti center caps on my oem 17 wheels (sorry donít know how high it was by measuring) and drove right pass it and parked.Im lowered on 350z springs and I have a Stillen z tube with stock box filer.I did not notice anything after driving through the puddle I even started it up an hour after I have parked and the car fired right up with no weird noises.Should I be worried??? Iím just afraid to get hydro locked but it seems my car is still running the same but a little part of is scared that maybe I will feel the damage later on.

Trust me you'll be fine, if you had any immediate water enter the motor it would have stalled and/or started making weird noises. Check your air filter to see if it got wet at all,. my guess is it didn't. You might want to warm up the motor and let it run for a bit idling wherever you park. That'll help heat up and hopefully dry out any components that were exposed to the water.

My 06 GTO flooded a couple of weeks ago and it's going to be totaled, the amount of the repair is huge. I was driving and the water literally went from a couple of inches deep to the top of the tires in a matter of seconds here in our neighborhood. The car's market value is a little over $14K and the repair estimate is right at $13K. Sad times here my friends, sad times.

The air is drawn from right where the hood meets the grill, unless you hit the puddle pretty hard you're not going to ingest water but like BD said you should still pull the filter and make sure it's not damp.

What were the symptoms you had after going through the water?

I would be more concerned about water at that depth finding its way into the cabin and frying the BCM since it sits pretty low.

But since u just drove thru it, the water probably didnt have enough time to get in.

After I got out of the water the motor was running a little rough and had a light clicking sound from the front of the motor which went away by the time I had driven 2 blocks to get back to the house. I waited an hour after I got home for the rain to stop, went outside to start the car with the intention of letting it run for a while to dry out the engine bay and when I started it the motor had the sound of death, rod knock. I shut it down, came inside and made an insurance claim immediately. Strangely the rear floorboard was soaking wet but the front floorboard was dry as a bone.

The BCM is the body control module, one of the main computer systems that the car uses to run correctly.

"Body Control Module". Just Nissan's fancy name for computer. It controls a lot of the electrical functions on the car. Some security stuff too.

Located behind the fuse box in the driver's side lower left kickpanel.

I just got off work and I havenít touched my car since I parked it about 8 hours ago.im coming home now to try to dry it out by starting the car and let it warm up and I will Continue to investigate as I will be driving it tomorrow all day.I hope nothing is wrong as I just bought the car 2 months ago and I really fell in love with how it drives and I already invested a good amount on cosmetics as well as engine work.Last thing I want is to total my car for driving through a puddle that I couldnít avoid.I thank god my appointment for coilovers install is next week I could only imagine being lower than I am now and going through that haha.Now that I remember I recall going through the same type of puddle in my old 5AT sedan and all that happened was my headlights and gauge lights were cut out and I had to replace them.My 5AT was slammed compared to my current 6mt sedan.

Totally normal for these engines to have valve noise like that, they usually start developing it around 30k miles.

EDIT: When I say NORMAL, I mean they all do it. Mechanically speaking there is some excess play between the cams and lifter buckets but it's a common occurrence and not something you need to be concerned with for a daily driver. If this was solely a track car then yes you would take new measurements and install different thickness of lifter buckets. If it was a LOT worse then you would probably need to get it fixed, but it's not...

See if it still persists in a week, when you flood out the bottom of the car you end up with mild corrosion on everything the next day. Could have been something got crusty overnight.
