I live in Mass.It poured like hell today.I was driving to home depot.I rounded a corner and there it was,,,,A puddle half way up to my headlights.The car started bogging and there was nothing i could do.I had a buddy with me and we got out and pushed it out of this puddle.The car wont start.My brother in law picked it up with his flatbed and told me that if theres water in there its done.When it died it would'nt turn but after a few it did until the battery was dyin then it locked up again.So my brother in law starts clockin miles on the trip and says he is gonna charge my ins company and says i need a new engine probably.I dont want to be taken and any input would be great.By the way ,I am takin my cai out and goin with the stock airbox cause i dont think that this would have happened if my air filter was'nt way down n the front fender.

wow that sucks a lot, im pretty sure that trying to start it after you knew water was in there was a bad choice. But hey maybe you can get some more hp out of this with a nice new engine... try to make this a good thing, thats what i would do
keep tryin to start it man my friend thought his 4 runner was done and low and behold it started up just fine a few days later. Might have to hold the gas to the floor when you start it though. You might want to try this!
Regardless of the cause, treatment is the same. Removal of the spark plugs will allow access to the combustion chamber. By inserting an irrigation syringe fitted with a flexible plastic tube on the end, you can suck out the liquid that infiltrated the combustion chamber. Once all the fluid is removed, the chamber should be sprayed with a liberal coating of a water displacing lubricant such as WD40, and allowed to sit until the remaining water has evaporated. Once the water or coolant has been removed, inspect the combustion chamber for rust. The best option would be to remove the head, but a borescope or small flashlight and mirror will also work. Light surface rust will be normal, but if you see any heavy corrosion, it should be gently removed, and vacuumed out of the chamber. After inspection, pour a tablespoon of assembly lube (such as Marvel Mystery Oil) or clean engine oil into each combustion chamber. Attach a socket to the crankshaft, and slowly rotate the engine through a few revolutions. (Make sure that you turn the engine in the proper direction, see a service manual for proper rotation direction.) If you hear any clanking, or harsh scraping, you should bring the engine to a competent mechanic. After verifying that the remaining systems are free of water (electrical, fuel delivery, air intake, distributor, etc.), re-install the spark plugs and wires, and attempt to start the engine.

i thought my car was done 2 months ago. i hit a huge puddle and sucked water through my intake. turns out all i had to do was clean my MAF off, i put my stock intake back on (not going through that again) and it fired right up.
from what i was told the filter basically has to be submerged for you to get enuff water in your engine to hydrolock it. start with cleaning your MAF as i'm sure you atleast got some water in your intake tube, and let everything dry up. then see if it will crank.
mustang wasnt fast enuff so...

I,m gonna try ans start it tommorrow night after work.My one issue is i heard that if its hydrolocked i can bend a valve.I think my brother in law is lookin to get money outta my ins company for the tow and storage already
Ok it is more then likely not "hydrolock". Hydrolock is when the water gets in the engine and wont compress like air and it bends a rod. The only way to do that is to have the engine at 6000rpms and drive in a lake. What you did was get the maf wet. When the maf gets wet it dumps fuel and the engine dies and wont start. You maf have gotten some water in the engine but i doubt it. Pull the plugs overnight and take off the maf and clean and dry it.
Im callin to work today.I think that im gonna be a dad again,So first thing this ami am going down to the shop and try and start it.My battery was dying last night and the hazzards were barely workin.Thanks for all the responses.I will let you guys know how everything goes
3/4 in spark plug socket, couple of extentions (wobble extenstions are best) and a socket wrench. Your brother-in-law sounds like a dick. If my brother-in-law charged me for a tow I would kick his ***.
Just got back from the shop.He had it in the garage with a battery charger on it.We pulled the plugs and 4 of the eight plugs had ice in the gap.I tried to turn it and it did'nt budge.I was thinking doin it by hand might be better.Anyways,he said to let it thaw out a bit in the shop and we'll try it again later.Wish me luck!
This happened to a friend on mine's son's 98 Cobra. The engine was blown and the insurance company gave him $9k for the car. He bought it back for $300 and rebuilt the engine and had a profit. That is the way i would go, I wouldn't worry about the old engine. You could afford a Termi engine for that....

if its gone take it to a engine shop and have them machine the block if its not cracked, and polish and port the heads. then all forged internals and some cams since its all apart. sounds like alot but now would be the time to do the work while its apart.
