No matter what the owner wants to do with this, I do hope we get an autopsy video of that engine, call it a public service video to show what happens when you hydrolock an engine
Better yet, if the owner decides to scrap the car, Ray should get hold of the engine and send it to Eric. On a crate. Held together with a million screws. 😄
I had this happen to me in 1985 to a 1974 Ford Bronco that sat submerged for two days. An old mechanic told me what to do to possibly save it and it took me a week and a hundred dollars of fluids (at that time fluids were cheap). Drained and flushed axles, transfer case and transmission. Pulled the oil pan, drained the oil and water and then filled the engine with kerosene and let it sit for a day. Drained the kerosene and then filled with a 50/50 of kerosene and oil and let it sit another day. Did that four times. Then drained and filled with fresh oil including putting an ounce on each piston through the spark plug hole. Finally cranked it over and it actually started. Ran it to temp, drained and refilled with new filter and did this three times. After all of that the vehicle actually ran without an issue and surprisingly had better compression and ran better than it ever did. Amazing!
This will usually work as long as there is just water and no sand. Sand is an engine killer for sure. Back in 72 a guy at the auto supply bought a new flood car brought from Oklahoma that looked like new, but the engine and transmission only went a few miles before destruction because of sand.
@richardstone5241 I got lucky when I did this, the car was cold, so unlike when I had previously done it, the engine stalled because the electrics got soaked. Once it time to dry off, it started up fine. Sitting in the puddle for 15 minutes did mean that I ended up replacing both CV joints eventually, but that was under warranty. In another case, my friend ended up with a Honda dream pulled from a pond. He replaced the oil and filter,, then we spent 20 minutes kicking it over. Replaced the oil and filter again, and the plugs, then after another 10 minutes got it to run. Ran it for 10 minutes, and replaced the oil and filter *AGAIN*. After that it gave no more trouble.
Yep, that engine's soul went to meet its maker. I started praying for it the moment you started blasting air into the cylinders. RIP little Kia, you had a short unfruitful life.
Ray, the PSA you are looking for is: "Turn around! Don't Drown!" This applies to human drivers and passengers, non-human passengers, as well as engines of all varieties.
Yeah but the problem is that many times when you think it is time to "Turn around" you are already too far into it to do that because the water is rising just as fast BEHIND YOU as IN FRONT OF YOU.
I’m an ex mechanic living in England I remember working on a car that had driven through a flood it had picked up water into the engine tried to compress the water which of course is impossible so it smashed the piston bent the con rod which then proceeded to drive itself through the block.
Ray after the rings and walls got wet there would be no compression because it severely washed the walls and rings, you need to put some oil (Like 1/4 of a cup) into each of the cylinders to re-lubricate the rings and walls to build compression. Then turn over the engine with the plugs removed, It's possible that you will have enough compression then. Then re-test with your compression tester.
No dude. A piston and rings bone dry in a dry cylinder will simply have way more compression than you may realise. All of that air isn’t just magically going to go sneaking past the piston. This has no doubt bent the rods, damaged the timing system and pistons kissed the valves or a combination of it all.
@@michaelslee4336 Having rebuilt a lot of engines and having fixed engines that have sat for decades I can tell you it's the oil on the cylinder walls and edge of the ring / on the piston ringlands that absolutely makes a seal and yes you can have 0 compression with dry cylinders. Especially in modern engines with lower tension piston rings for fuel economy and/or plasma sprayed and polished cylinders.
Too bad. I once owned a KIA Rio. Great little car got 40+ mpg on highway with adequate power. RIP 2.6 engine. Great video as usual Ray. Have a great weekend with your kids and wife unit.
back when i was in college, another student drove his Ford Fiesta into a Flooded lowspot in our parking lot. it promptly died. it hydrolocked so hard, that 2 connecting rods were bent!
When I was a kid, the main road coming from town to our rural neighborhood had a low spot that would flood occasionally. During one of these rare floods, my neighbor went out there with his Ford tractor so that he could pull hydrolocked cars out of the low area. One idiot with a little convertible sports car went through after being told not to, and hydrolocked his engine. My neighbor told him NOT to try starting it. He told him he to wait for the tow truck. He completely ignored my neighbor, and got in the car, and cranked the engine over. Bad things happened. Stupidity.
I'm no mechanic, but I have heard, that if an engine hydro locks, NEVER try to re-start it! I remember this, in my Sea-Do manual. It stated, that if the unit capsizes, or the engine stalls, to remove the spark plugs, and clear the cylinders, before attempting a re-start. It really does make sense, that when an engine stalls, due to hydro locking, it just stalled, and, while the engine did ingest water, it only stalled. The attempt to restart the engine, is when the real damage occurs. This would be the best case scenario, on an engine, running on lower RPMs. If the engine hydro-locks at high RPM, the momentum would rip the engine apart. It sounds like they really went at it, trying to get the car to start, instead of taking a breath, removing the spark plugs, and clearing out the water, before trying to start the engine. I knew someone, many years ago, who tried racing his brand-new Challenger through flood water. The resulting hydro lock, because the engine was at high RPM, destroyed it! The dealer laughed at him, when he had it towed in, expecting them to replace the engine under warranty. The only thing that saved his hide? His insurance company paid to replace the engine, under the stipulation, he was trying to get to safety, during a flood. What they didn't know, is he was just being an idiot...
The issue when you start a hydrolocked engine is water does not compress so when the engine tries to compress the air fuel mixture the water resists it causing all sorts of possible damage, bent rods, damaged pistons possibly even damaging the block because the water has nowhere to go. Best thing to do is exactly what Ray did, pull all the spark plugs and crank the engine to fire the water out, you still have no guarantee that it will get all of it out though
@@Delsus89 Exactly! Where an engine, running at low RPM, hydro locking just stalls the engine. But when you force the engine to turn over, with a starter, things start to break. But if the engine is running at high RPM, the momentum will kill it.
@@Delsus89as long as you get even 90% of the water to cylindar volume out, running it will clear out the rest, and the cylinders get a slight steam cleaning
Just once I've had to deal with a hydrolocked engine. It was on a riding lawnmower with a single cylinder engine. A piece of crud got caught under needle in the carburetor, and let the half-gallon of gas in the fuel tank completely drain into the engine. Thankfully, that beast had a translucent plastic fuel tank, and a cutout in the body fairing, to where you could easily see the fuel level. I couldn't see any fuel in the tank, which puzzled me, since I knew it had been half full when I finished using it the week before. Pulled the oil dipstick - level was three times higher than what it was supposed to be, was incredibly thin, and smelled of gas. Then pulled the spark plug - and gas came pouring out of the plug hole. When I tried cranking it over, it shot gas over 6 feet out of the plug hole. Thankfully, because I'd caught it before trying to start the beast, it was just a matter of rebuilding and cleaning out the carb, and draining, cleaning, and relubricating the engine. And I got rid of that wire mesh gravel screen 150 micron filter they'd put on it from the factory, and put a proper fuel filter along with a fuel shutoff valve on it.
When I saw the Kia on the truck in the background of your earlier video, I thought - that is going to make a brilliant video in a short while, and it did - thanks Ray, I really needed that.
In fairness to the owner (and I have been in a similar situation) when your engine dies and you are stuck in rising water, you begin to panic. You aren't thinking about the engine hydrolocking, you are desperately thinking about "how the hell am I going to get out of here?" and keep cranking. Yeah its crazy and hindsight is 20/20, but panic can override common sense quite easily.
Never a good idea to just drive thru standing water if you don't know how deep it is. Yet, I see people do it all the time. I remember watching a news clip and it showed a vehicle floating and another driver coming down the road towards them and just drove into the same deep water and got stuck. Why? :)
So, one cylinder ingesting water will cause the engine to stall, and if anyone has seen a diesel with an injector stuck open, you'll know this. For all 4 cylinders to have ingested water like that, and for all 4 cylinders to have bent rods, he was going pretty fast and at a rather high RPM for it to overcome the force of steel rods bending. I would really like to see the aftermath of this.
Hydrolock is no fun! Back when I was a Warranty Engineer for the US operation of a MAJOR Diesel engine manufacturer (German air cooled to give you a clue) we got an engine back claiming "Factory Defect" as they always did. Never mind that in 8 years we found only FIVE actual factory defects! The rest were abuse, neglect, misuse, and even downright sabotage! This one was a real doozy! Engine came in with holes through both sides of the block, full of fresh oil right up to the holes, and a new (dry) oil filter installed. We knew something was "fishy" about it, especially from the smell after it sat in the shop for a few days! The customer claimed they went to start it one day and it was locked up. Yeah, right. So how do you explain the DEAD FISH we found ON TOP of the engine when we started digging into it? After telling them what we found they admitted the machine was in a rock quarry that flooded, and they tried to start it and drive it out. Yep, hydrolocked, and with the almost 100Hp starter these things had (BIG engine) it bent most of the connecting rods (about the size of your leg from the knee down) into a "U" shape! No free engine for YOU!
You think people would realize in any small or midsize cars that YOU don’t drive through high water will get water through the air intake!! Especially mustangs, Corvette the air intake is on the bottom. I drive a Tacoma TRD PRO with an ARB that is placed in the tall light and run to trans and rear breather valves so I can run in high water also a snorkel. I cringe as I watch people drive through water. I think to myself why!! Your dad didn’t tell you this glad my dad worked for ford for 43 years and I read a lot of OFF-Wheel Drive Magazine. Ray thanks for your service and commitment. I am sure you have transmission and rear differential Air breather. ARB makes the best very easy to install!!
Knowing that Ray exists makes me happier to be on earth at this time. Love this guy and learn stupid amounts of knowledge and strategy from him (and buy as many tools he uses as I can)
Sucked water into a bike engine once....but...she lives still. I took the plugs out before I cranked it. Got the water out. Rode her home gently, swapped the oil and filter, flushed out the oil tank ( dry sump) to get rid of contaminated oil and any water that was in there, and all was good. As a precation, she got a further oil change after a week, so any moisture inside would have got either boiled off or emulsified. Fresh oil. When you hydro lock a motor, the temptation is to try and turn it over and pump out that water. No. Under compression, ALL the valves in a cylinder are closed. Water won;t compress, so something else has to give. Rods. Pistons. Rings. Head gasket .... it's got to go somewhere.
I am wanting to say that is in the Bradenton/St. Petersburg area of Florida and if that was the result of a hurricane that could be storm surge that contains salt water. Water cannot be compressed. There is this road in England that goes through a creek called Rufford Ford. It shows clearly what happens when water gets sucked into an engine. Ray's truck didn't suffer the same fate because the engine is above the water. However, he correctly said not to do this....GREAT VIDEO!
My son's KIA Rio 2012 model lost the belt tensioner pulley it fell off the weld for the bearing shaft broke while driving as a result it took out all the intake valves , pulled the head checked the rod heights and replaced the valves , all good now. Good job Kia Rio's have really thin valve stems they bent with out doing any damage other than kiss marks.
Got lucky many, many years back (Summer of 1977) when I drove my little Chevette into some water just a bit too fast. As I was only a couple blocks from the house, I pushed it home (very easy with that small car), pulled the plugs and let it dry in the heat for the rest of the day. That evening, started up fine.
I agree with the others, I’d love to see a tear-down on this one. With zero compression and the pistons still present, I want to see where the air is going.
I dodged this bullet when my Ford pickup with a 390 blew a head gasket. I was driving back from a job, stopped at a store, when I restarted it there was a big puff of steam out the exhaust, I drove it a couple of miles to my shop and backed it in. I came down the next day and pulled all of the plugs before I cranked it, one cylinder was full of coolant. I tore it down and replaced the head gaskets, all was well after that. Had I tried to crank it, things would have been way different .
I recon like a lot of people spied their chance to get rid of their car for an insurance pay out they ditched it but i am not saying that the owner of this car did .thanks for the video
20 some odd years ago when I was a younger man. My buddies little brother drove his 91 Jetta into a huge puddle after a massive rain storm. Towed it back home using tow straps. Pulled the Plugs, removed the intake, Turned it over and shot water all over the garage, Dropped the oil pan. Replaced it all with ew oil and Plugs and she fired right up. Somehow no lasting damage to that engine. im guessing this was around '98/99
I really like seeing that Kia put the A/C expansion valve on the firewall, as opposed to on the other side of the firewall, so it can be easily replaced. I recently had to take some dashes apart to get to those on some Toyotas and Hondas.
Ray, this is your chance. Pull the engine and ship it to Eric to see what failed. Package that thing up like Fort Knox. I want to see Eric have to disassemble a house to unbox it.
When I was young, I drowned my used 280zx. The next day, my Dad and I towed it to his house with his Camry. After a bunch of arguing, I pulled plug #1 and my Dad cranked it. I got a column od water with fuel in my face! Six new plugs and a bit of timing and I was back was back on the road.
A timely video, because my son recently did this very thing. His engine actually runs; however, but has a very loud tapping noise, which sounds like a collapsed lifter, even though this engine has solid lifters and overhead cams. Have yet to go any further with it.
Hey Ray, I just went back and watched one of your videos from 2 years ago again.. you worked on a 2007 suburban that ended up being a scam of sorts. The tranny was in limp mode and wouldn’t shut off. You found a little blue wire that bypassed the fuel pump and caused the battery to drain overnight. I was just wondering if that owner has come back to you now that you’re in your own shop? I love you videos and content. I just wish I wasn’t in Idaho and could come to you for my vehicle maintenance. Thanks for your honesty and integrity.
We have a boat with twin 454s. An oil cooler failed and when I shut the engine off water got sucked into the oil. It did not get int the cylenders to make them wet. Changed the oils 4 times and it was still slightly milky. Ran it for 20 hours and it cleared up. Changed the oil again and it worked fine. Have run the engine 1,500 hours since then and it still works. Water like you have one would assume mechanical failure of rings or valve or head gasket. Be interesting to see the cause. Since it turns over without noise a cheap (A few hours $600) look would be to remove the head.
The memory only gets worse Ray as you get older im sorry to say. I am 65. Been a mechanic for over 45 years. I have a fine collection of multiple tools because I keep "loosing" them and buy replacements. But i too easily remember useless crap, information,places I've been to and(don't tell the old lady) old girlfriends. Good luck !
I remember from about 2.5 years ago when there was heavy rain here with lots of flooding. So many cars were being towed away due to trying to ford water. I remember one in particular occuring when I was there. The guy kept trying to start the motor. You try to tell them not to, but they do anyway. I opened the bonnet, took the air filter off and it has at least 2 litres / half a gallon of water in there which was overflow from what was already in the motor (full on waterlogged air filter). Sure, I drove through some water (after evaluating the depth from other road users) but I did it super slow (so slow that others were impatient and passing me) as I didn't want to ingest water. Years later, my car is still good as it only just splashed the rims (at best)
Since there was so much water in the engine it is highly likely that all of the oil helping seal the rings was washed away. I was working on an MGB that came in with 0 compression. Found the chokes had been stuck open (washing the cyliners down). I put some oil in all the cylinders, let it soak for a while, cranking it and compression was well above 100 in all four cylinders. Fixed the stuck choke problem, changed the oil and it was fixed. So, there is chance with oiling and engine flushing this KIA could still breathe.
I pushed a car out of 24 inches of water, I told him to have someone pull the plugs before even trying to start it or he could ruin his engine. The only reason I pushed him out was because there were about 15 other adults just standing there when I showed up and his 2 year old daughter was crying in the back seat while the water was still rising slowly with rain still in the area. I pushed his car up a mild grade and when I got it out of the water is when a couple of guys finally came to help push the car around the corner. I only stuck around long enough till his daughter calmed down and I left cause it could have gotten ugly with all those adults there and myself. Love you Ray but this video just brought back some very bad memories from a couple years past.
The first thing to do is check the air cleaner if wet pull the spark plugs then turn over it when the cylinders cleared change the oil and dry the spark plugs or replace them and check the fuel system for water
Changing the oil is a waste of time and money. When an engine shows ZERO compression, there is no point in going any further. Hydrolocking is always 100% fatal for an engine. Water does not compress and when a cylinder gets a lot of water in it something is going to give. 3 of the spark plugs were loose and that means the water tried to push them out through the spark plug threads in the head.
@@RMartin631not true. If you’re driving slow through water and it hydrolocks and shit off, as long as you don’t try to crank it again, you may get lucky. First thing you do is pull the plugs. Then crank it until no water sprays out. Then you should be good if no damage occurred when it initially died.
@@RMartin631 I actually had my Jetta die on me in some water. I didn’t realize how deep it was, because it was dark out. I had the 2.5l 5cyl. I pushed it into the parking lot, pulled the plugs and blew the water out. Put the plugs back in, and it started right up. Smoked for a lil bit, but it was good to go with zero damage. So yeah, not 100% fatal. 👍🏻
Looks like the first chamber valves were both stuck open and it looked like the top of the piston had been contacted, so that will be why they are all low on compression, and if 3 and 4 are communicating there was a serious series of catastrophic impacts before the engine shut of.
Yeah, maybe the driver of this said vehicle drove through the SAME high-water crossing that Ray drive through in his lifted pick-em-up truck several videos ago, primarily because he saw Ray drive through said high-water crossing! What are the odds? 😆🤣😝 Reee….!
My brother did this to his '94 Volkswagen Golf; He was driving on Bumby Avenue, underneath highway 408 through deep water. And of course Chris has the brains of a goat, what does he do? He goes flying right through it and the 2.0 liter 8 valve engine sucks in water. It hydrolocks and the result is four bent connecting rods. New engine. Which mommy and daddy paid for. -Spare the rod, spoil the child folks. My parents never made Chris pay for his mistakes. He still lives in their house in Asheville at the age of 52. He'll do it next to his 2023 Subaru; It is only a matter of time~
There may or may not be bent rods. It's obvious they either cracked the head or blew the head gasket though, at the very minimum. No way to tell how extreme the damage is without disassembly. If it is just the head gasket though, they got very lucky. I suspect it's a lot more than the head gasket though.
@@JohnADoe-pg1qk I have an EV myself. And while I theoretically could drive through water and the motor would be fine (there is no way for anything to hydrolock and it's all sealed anyway)...I wouldn't do that. Because water ingress into the car can still corrode things and damage wiring and electronic components.
@@JohnADoe-pg1qk I'm just pointing out that driving through water is bad, even when it is supposedly "safe". Unless you have one of those ambibious vehicles like WaterCar where they are specifically designed for it. If you have a WaterCar Panther, sure go into the water.
Make sure you use the correct shrader valves for your compression testers. They have much weaker springs than regular shrader valves to allow air to pass through
Yeah. I had a 2000 ford Explorer with the 1999 Mustang 5.0L 302 CI engine. I went through a flood and stalled it out. After being extracted, I removed the air filter and cranked till it blew a stream of water out about 10 feet behind me. It actually fired right up and ran. I feel that I was pretty lucky.
That happened to someone I know. Many years ago he got stuck in a flooded parking lot with his corvette and it hydro locked and bent a rod. It took some doing but his insurance did eventually pay for a new engine.

The issue when you start a hydrolocked engine is water does not compress so when the engine tries to compress the air fuel mixture the water resists it causing all sorts of possible damage, bent rods, damaged pistons possibly even damaging the block because the water has nowhere to go. Best thing to do is exactly what Ray did, pull all the spark plugs and crank the engine to fire the water out, you still have no guarantee that it will get all of it out though
Makes sense, water hardly compress at all, so something is going to blow from the insane pressure. Valves, pistons, the block, etc...
@@Delsus89 Exactly!
Where an engine, running at low RPM, hydro locking just stalls the engine.
But when you force the engine to turn over, with a starter, things start to break.
But if the engine is running at high RPM, the momentum will kill it.
@@Delsus89as long as you get even 90% of the water to cylindar volume out, running it will clear out the rest, and the cylinders get a slight steam cleaning
Just once I've had to deal with a hydrolocked engine. It was on a riding lawnmower with a single cylinder engine. A piece of crud got caught under needle in the carburetor, and let the half-gallon of gas in the fuel tank completely drain into the engine.
Thankfully, that beast had a translucent plastic fuel tank, and a cutout in the body fairing, to where you could easily see the fuel level. I couldn't see any fuel in the tank, which puzzled me, since I knew it had been half full when I finished using it the week before.
Pulled the oil dipstick - level was three times higher than what it was supposed to be, was incredibly thin, and smelled of gas.
Then pulled the spark plug - and gas came pouring out of the plug hole. When I tried cranking it over, it shot gas over 6 feet out of the plug hole.
Thankfully, because I'd caught it before trying to start the beast, it was just a matter of rebuilding and cleaning out the carb, and draining, cleaning, and relubricating the engine.
And I got rid of that wire mesh gravel screen 150 micron filter they'd put on it from the factory, and put a proper fuel filter along with a fuel shutoff valve on it.
Hi 👋🏽 Ray and wife unit and boys just finished watching video on Kia excellent work finding our what’s wrong and as always you all be safe 🇺🇸🇺🇸🇺🇸
When I saw the Kia on the truck in the background of your earlier video, I thought - that is going to make a brilliant video in a short while, and it did - thanks Ray, I really needed that.
Check out videos of Rufford Ford, where watching cars drown themselves became a spectator sport.
In fairness to the owner (and I have been in a similar situation) when your engine dies and you are stuck in rising water, you begin to panic. You aren't thinking about the engine hydrolocking, you are desperately thinking about "how the hell am I going to get out of here?" and keep cranking.
Yeah its crazy and hindsight is 20/20, but panic can override common sense quite easily.
Never a good idea to just drive thru standing water if you don't know how deep it is. Yet, I see people do it all the time. I remember watching a news clip and it showed a vehicle floating and another driver coming down the road towards them and just drove into the same deep water and got stuck. Why? :)
Ray, I dont agree with you. Its not Combustion Chamber, its the Combustion Palace! 😂
And in that combustion palace, we shall find some malice!
Maybe THAT guy could strip this car in his shop. 😂
...there is definitely a good video hidden inside that engine.
At least they brought it to you hopefully you can save the motor
Nice message starting at 3:16 on the back of the mom van.
At least the paint looks pretty good.
I was thinking the same, paint work makes it look like brand new car. Shame the engine is toast.
Looked like a Vegas water fountain!
So, one cylinder ingesting water will cause the engine to stall, and if anyone has seen a diesel with an injector stuck open, you'll know this. For all 4 cylinders to have ingested water like that, and for all 4 cylinders to have bent rods, he was going pretty fast and at a rather high RPM for it to overcome the force of steel rods bending.
I would really like to see the aftermath of this.
That thumbnail is the most impressive Kia 1.6 that I've ever seen.
From Randy in Chattanooga: There’s nothing wrong with the valve core. There’s just not enough compression to blow it open.
More likely theres a few bent valves in the engine that aren't shutting, plus the obviously blown head gasket...bye bye compression 😂
Hydrolock is no fun! Back when I was a Warranty Engineer for the US operation of a MAJOR Diesel engine manufacturer (German air cooled to give you a clue) we got an engine back claiming "Factory Defect" as they always did. Never mind that in 8 years we found only FIVE actual factory defects! The rest were abuse, neglect, misuse, and even downright sabotage!
This one was a real doozy! Engine came in with holes through both sides of the block, full of fresh oil right up to the holes, and a new (dry) oil filter installed. We knew something was "fishy" about it, especially from the smell after it sat in the shop for a few days! The customer claimed they went to start it one day and it was locked up. Yeah, right. So how do you explain the DEAD FISH we found ON TOP of the engine when we started digging into it?
After telling them what we found they admitted the machine was in a rock quarry that flooded, and they tried to start it and drive it out. Yep, hydrolocked, and with the almost 100Hp starter these things had (BIG engine) it bent most of the connecting rods (about the size of your leg from the knee down) into a "U" shape!
No free engine for YOU!
You think people would realize in any small or midsize cars that YOU don’t drive through high water will get water through the air intake!! Especially mustangs, Corvette the air intake is on the bottom. I drive a Tacoma TRD PRO with an ARB that is placed in the tall light and run to trans and rear breather valves so I can run in high water also a snorkel. I cringe as I watch people drive through water. I think to myself why!! Your dad didn’t tell you this glad my dad worked for ford for 43 years and I read a lot of OFF-Wheel Drive Magazine. Ray thanks for your service and commitment. I am sure you have transmission and rear differential Air breather. ARB makes the best very easy to install!!
Knowing that Ray exists makes me happier to be on earth at this time. Love this guy and learn stupid amounts of knowledge and strategy from him (and buy as many tools he uses as I can)
Sucked water into a bike engine once....but...she lives still. I took the plugs out before I cranked it. Got the water out. Rode her home gently, swapped the oil and filter, flushed out the oil tank ( dry sump) to get rid of contaminated oil and any water that was in there, and all was good. As a precation, she got a further oil change after a week, so any moisture inside would have got either boiled off or emulsified. Fresh oil.
When you hydro lock a motor, the temptation is to try and turn it over and pump out that water. No. Under compression, ALL the valves in a cylinder are closed. Water won;t compress, so something else has to give. Rods. Pistons. Rings. Head gasket .... it's got to go somewhere.
I am wanting to say that is in the Bradenton/St. Petersburg area of Florida and if that was the result of a hurricane that could be storm surge that contains salt water. Water cannot be compressed. There is this road in England that goes through a creek called Rufford Ford. It shows clearly what happens when water gets sucked into an engine. Ray's truck didn't suffer the same fate because the engine is above the water. However, he correctly said not to do this....GREAT VIDEO!
It lived up to its acronym... KIA - Killed In Action!
My son's KIA Rio 2012 model lost the belt tensioner pulley it fell off the weld for the bearing shaft broke while driving as a result it took out all the intake valves , pulled the head checked the rod heights and replaced the valves , all good now. Good job Kia Rio's have really thin valve stems they bent with out doing any damage other than kiss marks.
Got lucky many, many years back (Summer of 1977) when I drove my little Chevette into some water just a bit too fast. As I was only a couple blocks from the house, I pushed it home (very easy with that small car), pulled the plugs and let it dry in the heat for the rest of the day. That evening, started up fine.
I agree with the others, I’d love to see a tear-down on this one. With zero compression and the pistons still present, I want to see where the air is going.
Personally I would be checking all of the water in the oil. Good video!
I dodged this bullet when my Ford pickup with a 390 blew a head gasket. I was driving back from a job, stopped at a store, when I restarted it there was a big puff of steam out the exhaust, I drove it a couple of miles to my shop and backed it in. I came down the next day and pulled all of the plugs before I cranked it, one cylinder was full of coolant. I tore it down and replaced the head gaskets, all was well after that. Had I tried to crank it, things would have been way different .
I remember when those first came out. Drove the coupe version once, and it was peppy.
The song that comes to mind with this video is... Queen another one bites the dust.
I recon like a lot of people spied their chance to get rid of their car for an insurance pay out they ditched it but i am not saying that the owner of this car did
.thanks for the video
“Water, water, everywhere,
And all the boards did shrink;
Water, water, everywhere,
Nor any drop to drink.”
That would teach you about killing lucky birds.
Beautiful song by Iron Maiden. Poem by S. Coleridge.
nah i prefer "water water everywhere so lets all have a drink"
@@papaw5405 Drinking water is bad for one's health. It contains iron (among other things) and it will rust your stomach. I prefer scotch whisky.
20 some odd years ago when I was a younger man. My buddies little brother drove his 91 Jetta into a huge puddle after a massive rain storm. Towed it back home using tow straps.
Pulled the Plugs, removed the intake, Turned it over and shot water all over the garage, Dropped the oil pan. Replaced it all with ew oil and Plugs and she fired right up. Somehow no lasting damage to that engine. im guessing this was around '98/99
I really like seeing that Kia put the A/C expansion valve on the firewall, as opposed to on the other side of the firewall, so it can be easily replaced. I recently had to take some dashes apart to get to those on some Toyotas and Hondas.
Water also entered into the transmission, CV axle, and transfer case.
We used to jump a moped off the pier, haul it back up, pedal around the beach till it fired up, and repeat. Of course it was fresh water.
Ray, this is your chance. Pull the engine and ship it to Eric to see what failed. Package that thing up like Fort Knox. I want to see Eric have to disassemble a house to unbox it.
Great job love it 😊
I would like to see what the cylinders look like. That would be very interesting. Great video. Thanks
When I was young, I drowned my used 280zx. The next day, my Dad and I towed it to his house with his Camry. After a bunch of arguing, I pulled plug #1 and my Dad cranked it. I got a column od water with fuel in my face! Six new plugs and a bit of timing and I was back was back on the road.
So Cool Ray I have that same or similar Compression Gauge, Yup about 20 years old still worx. Aye on this engine. ty
Emotions (spending a huge amount of money is sometimes a verry emotional experience) are the conservators of our memories
A timely video, because my son recently did this very thing. His engine actually runs; however, but has a very loud tapping noise, which sounds like a collapsed lifter, even though this engine has solid lifters and overhead cams. Have yet to go any further with it.
Hey Ray, I just went back and watched one of your videos from 2 years ago again.. you worked on a 2007 suburban that ended up being a scam of sorts. The tranny was in limp mode and wouldn’t shut off. You found a little blue wire that bypassed the fuel pump and caused the battery to drain overnight. I was just wondering if that owner has come back to you now that you’re in your own shop? I love you videos and content. I just wish I wasn’t in Idaho and could come to you for my vehicle maintenance. Thanks for your honesty and integrity.
Hello from Higgins Lake Michigan
We have a boat with twin 454s. An oil cooler failed and when I shut the engine off water got sucked into the oil. It did not get int the cylenders to make them wet. Changed the oils 4 times and it was still slightly milky. Ran it for 20 hours and it cleared up. Changed the oil again and it worked fine. Have run the engine 1,500 hours since then and it still works. Water like you have one would assume mechanical failure of rings or valve or head gasket. Be interesting to see the cause. Since it turns over without noise a cheap (A few hours $600) look would be to remove the head.
The memory only gets worse Ray as you get older im sorry to say. I am 65. Been a mechanic for over 45 years. I have a fine collection of multiple tools because I keep "loosing" them and buy replacements. But i too easily remember useless crap, information,places I've been to and(don't tell the old lady) old girlfriends. Good luck !
Good day Ray and hi to Dave and new guy
I remember from about 2.5 years ago when there was heavy rain here with lots of flooding. So many cars were being towed away due to trying to ford water.
I remember one in particular occuring when I was there. The guy kept trying to start the motor. You try to tell them not to, but they do anyway. I opened the bonnet, took the air filter off and it has at least 2 litres / half a gallon of water in there which was overflow from what was already in the motor (full on waterlogged air filter).
Sure, I drove through some water (after evaluating the depth from other road users) but I did it super slow (so slow that others were impatient and passing me) as I didn't want to ingest water. Years later, my car is still good as it only just splashed the rims (at best)
Wow!!! Did the driver think they had a submarine??
You didn't show it, but I assume you drained the crankcase. Your videos are always very informative.
Good morning Ray
Since there was so much water in the engine it is highly likely that all of the oil helping seal the rings was washed away. I was working on an MGB that came in with 0 compression. Found the chokes had been stuck open (washing the cyliners down). I put some oil in all the cylinders, let it soak for a while, cranking it and compression was well above 100 in all four cylinders. Fixed the stuck choke problem, changed the oil and it was fixed. So, there is chance with oiling and engine flushing this KIA could still breathe.
I pushed a car out of 24 inches of water, I told him to have someone pull the plugs before even trying to start it or he could ruin his engine. The only reason I pushed him out was because there were about 15 other adults just standing there when I showed up and his 2 year old daughter was crying in the back seat while the water was still rising slowly with rain still in the area. I pushed his car up a mild grade and when I got it out of the water is when a couple of guys finally came to help push the car around the corner. I only stuck around long enough till his daughter calmed down and I left cause it could have gotten ugly with all those adults there and myself. Love you Ray but this video just brought back some very bad memories from a couple years past.
that's crazy - firing water like a geyser!
The first thing to do is check the air cleaner if wet pull the spark plugs then turn over it when the cylinders cleared change the oil and dry the spark plugs or replace them and check the fuel system for water
Changing the oil is a waste of time and money. When an engine shows ZERO compression, there is no point in going any further. Hydrolocking is always 100% fatal for an engine. Water does not compress and when a cylinder gets a lot of water in it something is going to give. 3 of the spark plugs were loose and that means the water tried to push them out through the spark plug threads in the head.
@@RMartin631not true. If you’re driving slow through water and it hydrolocks and shit off, as long as you don’t try to crank it again, you may get lucky. First thing you do is pull the plugs. Then crank it until no water sprays out. Then you should be good if no damage occurred when it initially died.
Give that a try with your GTI and tell me how it turns out.
@@RMartin631 I actually had my Jetta die on me in some water. I didn’t realize how deep it was, because it was dark out. I had the 2.5l 5cyl. I pushed it into the parking lot, pulled the plugs and blew the water out. Put the plugs back in, and it started right up. Smoked for a lil bit, but it was good to go with zero damage. So yeah, not 100% fatal. 👍🏻
Remembering details from long ago but forgetting things 10 minutes ago is called getting old
Looks like the first chamber valves were both stuck open and it looked like the top of the piston had been contacted, so that will be why they are all low on compression, and if 3 and 4 are communicating there was a serious series of catastrophic impacts before the engine shut of.
Very smart love your talent Ray
Oh look it's my engine!
Yeah, maybe the driver of this said vehicle drove through the SAME high-water crossing that Ray drive through in his lifted pick-em-up truck several videos ago, primarily because he saw Ray drive through said high-water crossing! What are the odds? 😆🤣😝 Reee….!
Owners biggest mistake (well 2nd biggest since 1st was driving through it) was trying to refire the engine after it quit..instant hydrolock
I was guilty of hydrolocking my parent's car in high school. We were lucky the engine survived. Still had it for a number of years after the event.
Stop the Clock!!! That time clock chime is Candleshoe Jody Foster movie from the 70's.........sorry did I say that out loud !
Cool video
My brother did this to his '94 Volkswagen Golf; He was driving on Bumby Avenue, underneath highway 408 through deep water. And of course Chris has the brains of a goat, what does he do? He goes flying right through it and the 2.0 liter 8 valve engine sucks in water. It hydrolocks and the result is four bent connecting rods. New engine.
Which mommy and daddy paid for.
-Spare the rod, spoil the child folks. My parents never made Chris pay for his mistakes. He still lives in their house in Asheville at the age of 52.
He'll do it next to his 2023 Subaru; It is only a matter of time~
There may or may not be bent rods. It's obvious they either cracked the head or blew the head gasket though, at the very minimum. No way to tell how extreme the damage is without disassembly. If it is just the head gasket though, they got very lucky. I suspect it's a lot more than the head gasket though.
At least the motor is not yet trying to fling parts of it into orbit.
@@JohnADoe-pg1qk I have an EV myself. And while I theoretically could drive through water and the motor would be fine (there is no way for anything to hydrolock and it's all sealed anyway)...I wouldn't do that. Because water ingress into the car can still corrode things and damage wiring and electronic components.
@@StormsparkPegasus I'm sorry, but I don't understand how your response fits to my comment. I didn't wrote anything about electrical vehicles.
@@JohnADoe-pg1qk I'm just pointing out that driving through water is bad, even when it is supposedly "safe". Unless you have one of those ambibious vehicles like WaterCar where they are specifically designed for it. If you have a WaterCar Panther, sure go into the water.
This is a great opportunity for Ray to use those thousand screws and send this engine to Eric at I Do Cars -- payback.
Your recent videos remind ne of the 8mm film videos of years gone by... Jerky, jerky, jerky
Howdy from Cali Motherlode! Keep on truckin man!
thanks Ray
Make sure you use the correct shrader valves for your compression testers. They have much weaker springs than regular shrader valves to allow air to pass through
Yeah. I had a 2000 ford Explorer with the 1999 Mustang 5.0L 302 CI engine. I went through a flood and stalled it out. After being extracted, I removed the air filter and cranked till it blew a stream of water out about 10 feet behind me. It actually fired right up and ran. I feel that I was pretty lucky.
Someone once told me engines are essentially air pumps. air compresses water does not.
Top man ray great vid as usual
It'd be kind of nice to see an engine rebuild on that. Hopefully the customer is financially secure enough for whatever they decide to do.
No one is rebuilding that engine. Most likely just throw a used engine in it to replace it. Waste of time and money to rebuild on this turd.
Thanks for the good video.
new car time
Another one BITES
Holy shit! Just like Old Faithful!
That happened to someone I know. Many years ago he got stuck in a flooded parking lot with his corvette and it hydro locked and bent a rod. It took some doing but his insurance did eventually pay for a new engine.
YAY Justin!
