Bending Steel With Water: Inside a Hydrolocked Porsche Engine
ฝัง
- เผยแพร่เมื่อ 25 ก.ค. 2024
- ►The Porsche Cayenne Turbo is great for many things, including towing boats, taking the kids to school, beating WRXs at highway pulls, and climbing over rough terrain. However, their V8 engines aren't impervious to damage, as our Creative Director Ben Marouski found out in the Colorado wilderness. While traversing a river crossing, his 957 Cayenne Turbo ingested water, causing it to hydro-lock and die. While Ben and his rescuers were briefly able to get the Cayenne running again, the engine's fate was already sealed.
You can watch all of the action with that Cayenne, from its assembly as an overlander to its demise and eventual rebuild in another video series, but today, it's all about looking at the carnage caused by the water. As we know, water in the cylinder of a running engine is catastrophic, and inside this Porsche M48.51 V8, that's all on display. So sit down, grab a snack, and watch along as Ben and Event Director/Cayenne Expert Nate Brown tear down the once-beating heart of a 957 Porsche Cayenne Turbo.

you've heard of Avatar: the Last Airbender, well here we have Cayenne: the Last Rodbender
I once inspected a four cylinder engine from a Kia sedan. The guy picked it up from a service, drove out and shortly after drove through a "puddle". Ingested water, stalled, engine locked up. Here's where it gets interesting... he had offered some of the workshop staff a ride because of the rain and in a moment mental failure, they helped him push start the car. He drove home, had the good sense to remove the airfilter and let it drip dry. The next day he simply carried on using the car until "that" moment when the damaged rod gave up and tore the engine apart. What came out of that engine was multiple bent rods, with the broken one having bent well past 60⁰. Somehow the engine kept turning. Somehow this guy managed to ignore his engine light, the noise, the misfiring, the soaking wet airfilter...
Holy Moly an Engine teardown, I can't sleep now....
It's foolish to add insult to injury, I'm sure this man has regrets. At least he's owned up to his mistakes and is willing to share his experience and this great teardown video of a hydro locked motor. Most people would shy away from something like what he's done, because of pride. Great video guys!
Appreciate the kind words Michael Strong Bow - the reality is Ben has owned up to his mistake all along, and has tried to learn from those mistakes as we bring everyone along for that journey right with him!
Oh wow! Hope I never have to get that deep into my engine! Just finished with replacing the CV axle on my '09 GTS - lessons learned : (1) if doing a CV axle, consider going all the way and replacing upper and lower control arms - you get new bushings, ball joints, and boots; and don't care if you damage anything during removal - so it ends up being much easier and faster, (2) if not replacing ball joints, be aware that new boots that match the old ones are hard to find, so take a lot of care, (3) if you have to tap on the stud to separate the ball joints, don't forget to leave the nut on the end of the stud to protect the threads - or be prepared to spend a lot of time with a thread chaser and/or thread file to repair the threads, (4) If you will be taking a long time, get a battery keeper - a dead battery is a pain, as the power locks and power seats won't work - and you need them to open the back hatch or to access the battery under the driver's seat, (5) note that an after market CV axle may have a different sized axle nut than the original - new one was larger then my largest socket, which fit my old axle nut, (6) brake shield bolts are the same diameter and threads as the bolt that goes in the brake pin - but not the same length, and one has a flared head - don't mix them up.
Lotta good notes there Johnathon, the axle is a straightforward job on this car but as you mentioned there are some things that can certainly make it easier/more worth your while when unassembling and reassembling.
I have been eagerly awaiting this teardown :D I'm glad we finally get to see some of the (Emotional!) Damage
No shortage of emotional damage here Joanna Atkins 😂
This whole thin can be avoided by stopping before the water crossing, lifting the hood / bonnet and looking at where the air intake is. If its low, stop. If the air-filter box is high up just pull the lid off that for the crossing and stick a cloth in the low down intake. If you can't get the intake up high then turn the engine off and get a tow across and save yourself $10,000. Its been the fashion to fit cool air intakes low for power but in the real world with floods they are just rob-benders.
Another great video by FCP and crew. I'm glad you touched on the glued in coolant barb. I had mine pop off when I was passing someone on the highway and I was 2.5 hours from home. Luckily a small indy mechanic down the street was able to push the barb back into the crossover pipe and I'm like 3 months strong lol. I plan on slathering it with JbWeld marine or something soon because I need to be able to romp on it with winter coming soon.
That doesn't sound fun shuckydarns710 - glad you were able to patch itup though. Check-in with us after a year and let us know if the JB Weld fix works😂
only a few minutes in, just had to say this is great. I'd love to hear more on the the gen 1 Cayenne's engineering and design- the provenance of its AWD design for example- but this is an excellent contribution!
Glad you enjoyed it AM D - lot to learn from Porsche and its engineers
Thanks for sharing the inside of a cayenne engine, especially a blown one
Our pleasure KilmoreGroup - it hurts a little but some satisfaction in there as well!
I really enjoy the comparison of this engine to the Audi V8. For some reason, I assumed they'd be very similar due to VAG ownership and platform sharing between the Touareg and Cayenne.
That would make too much sense David! 😂
That thing is disgustingly complex
@@TH-camuser1aa The idea of something failing in there just hurts your brain.
Great .... Loved it
To do: add a Snorkel!
2 Snorkles* Top of the list Brian 😂
If you hadn’t blasted through the river I wouldn’t have this awesome tear down video. 🤟🏼
The way the timing chain was designed is great! You know that these engineers who designed it wanted to make sure that it will be happy for a long time.
Seeing an Audi as a kid was blissful but seeing a teardown of the Audi V8’s turned me off. Further engineering designs turned me off even further.
It is what it is. Great video!
Thanks for watching vjfajardo0728 - truly a nice simplified design.
Crazy how a masterpiece of an engine can get ruined by water.
I may have said this in a video a few years ago, but Sunex makes a very nice drip pan that fits on the long leg of an engine stand. Sunex 8300DP Oil Drip Pan. Theirs is built specifically for their geared engine stand, but I suspect it works on many. Others like Jaz Products 720-000-01.
(A geared engine stand is a wonderful thing, too.)
Every time Nate says "significant" it feels like he's saying FUBAR
I was hoping to see the infamous water pump, maybe you got it in another video. I'm glad this motor's timing is more simplistic than the Audi's V8. Kudos to Porsche, keep your dirty hands off the Cayenne VW. JK. FCP for the W!
Surprised you didn't install a snorkel on this build to keep the intake and exhaust out of the water.
We are working on it Sterling Sigurd!
All the reason to modify for h.p. go full send and make all the right splashes,just avoid deep water
Great video
Not wrong Moe - never a better excuse to upgrade than when you have to.
13:52 PIZZA!
Knew someone would spot it!
Air doesn't just act like a fluid, air *_is_* a fluid.
What's impressive is the rod didn't exit stage left and leave an inspection window in the block
Not wrong Bunky80 - impressive it all stayed inside lol
Did any body else get super confused when he started talking about the timing chain, how at first he called it a dual chain setup and how most newer engines use a “singer” chain setup, then proceeds to say it only has one chain (which is clear when you look at it even from a video). The amout of time and effort that goes into this video you would think they would at least try and be accurate with what they say
So this engine is rebuildable?
Full disassembly, full wash and rinse; then upgraded parts.
Damn, I remember seeing the cayanne just stop in the water😢
Sad moment.... one we will never forget
Did you note any bore score on the cylinders from the bottom? I didn’t see any from the top
I’m sure this video will be circulating around the Porsche engineering department 😂
We bring dishoner to the Porsche family. They will shun us forever 😔
I had to watch this a few times. 1:24
When I was in high school back in the early 1990s I had a 1989 Ford F-150 with the 300 cubic inch inline six and hydro locked it when crossing water on a camping trip. One of my connecting rods was bent and twisted worse than on this engine. The mechanic who tore it down said he’d never seen one that bad before. I wish I would’ve kept it as a reminder that water can’t be compressed and isn’t a good thing to introduce to your combustion chamber.😂
Pleaes tell us before attempting the aforementioned water crossing you said "hold my beer. " and then instantly hydro-locked the truck 😆Ben has since framed this Rod as a constant reminder of how not to approach deep water!
@@fcpeuro no doubt my experience wasn’t as costly as yours with the Cayenne. I learned a valuable lesson though.
Love the video but please use a camera with better auto focus. Open up the aperture and get more stuff in focus!
Watched the same video, bought a 957TT. Bore scoring and no more savings. Sadly now last Porsche. Still an FCP customer by the way :-)
The VVT system reminds me of an old Honda VTEC engine, but with buckets instead of rockers.
VTEC just kicked in yo! (Sorry we couldn't resist, but you're not wrong, it's amazing how ahead of the curve Honda was with the original VTEC system)
Interesting watch, but please sort out the focusing of your camera!
Will do Bunny Dog - thanks for watching nonetheless
Still waiting for the buyers guide for the next generation of Porsche Cayenne. I'm looking at buying a 2014 diesel and I need your experience and expertise on that or regular gas engine. Will it run on biofuels?
Promise itll be out 2023 mrmitch1000 we didnt get around to it this year sorry!
@@fcpeuro 🙏🏾 you can get at me in the video for harassing you for a year 🤣
Great series!! Hey would it be possible to get one of these camshafts? I’d like it for a lamp project. Thanks!
We could certainly make that happen PatTheCarNut - we have em sitting here in the shop on the shelf. If we send you 2 will you make us one!? 🤔
@@PatTheCarNut We've got a bunch we can send- email benjamin.marouski@fcpeuro.com
I hope Infiniti paid the Portsmouth Sinfonia for that gem.
Maybe it's just me, but I never equated a Cheyenne to an adventure vehicle. I always see them as a fun essentially city A-B vehicle like a Subaru Forester.
When you driving in deep water actually moving very fast is bad cos water will go everywhere and especially into your intake. Better entering the water gently and accelerating steady
Ben went in waaayyyy too hot no doubt !
I will say Porche builds some mechinacally nice engines. Only as complex as is needed, not complex for the sake of being complex like Benz or the other German makers
Proper German engineering from the team in Stugart.
So rebuild or nah? It would be fun to see it get forged internals then do a big turbos project.
As much as we wanted to use this as a time to slap some big turbos and a stout bottom end - we got a junkyard engine, refreshed everything we could from our site, and got it back in the car in one quick weekend.
in rufford ford , they have everyday hydro locks
I love Rufford
If it got water in it after a water crossing, why WHY did they try and start the engine afterwards???
These are great engines until someone thinks they are a submarine and get water into the cylinders. Water and electronics don't mix very well, so why do some crazy people take them into water? Cars with electronic emergency brakes also can lock on so you can't get out of the water once you are in there. This is often seen with the newer Audi's.
GREAT VIDEO GUYS, BUT THE CAMERA MAN NEEDS TO LEARN HOW TO HOLD THE CAMERA AND FOCUS.
Are you going to rebuild it?
Didnt necessarily rebuild this engine, but did swap it out th-cam.com/video/mrmFZ10HgUA/w-d-xo.html !
So what did we learn kids today? We learned the reason of why you shouldn't drive a car into a river (probably without) a snorkel
Ben certainly learned....
I didn't see the original video--no snorkel and not proper speed to create a wave? Did others have snorkels or just timed their crossings better?
Check out the original video here - th-cam.com/video/lpsiTAKLTq8/w-d-xo.html -- but best guess is a combination of speed, intake baffles not being present on the front of the car, and bad luck.
7:05 who THE FK thought that was a good design? Idk how you look at that design and say "no, that won't be problematic at all."
Porsche makes famously reliable cars. 33 years of daily driving were very solid and free of the troubles I’d expect. I had normal cars before and a number of trucks, so I have a little perspective. Solid design and implementation. The Audi chain fest is a little painful to see. I’ve worked on all my cars and I can say that coming across that design is a total buzzkill.
That's not a bent rod, it's just a low compression cylinder for emissions. Haha.
😅😅😅
Too bad you guys didn’t try to pull spark plugs before cranking over.
Plugs were pulled, cranked it for a while and got what water we thought to be stuck in there out, and unassembled as much as we could trail side - but clearly didnt get it all out 😳
Tiny turbos
just little guys. Car only makes 500hp
Is that baby repairable? Is it worth it?
Ben may have to turn it into a coffee table at this point...😅
Are those volkswagen engines?
The super complex timing chain systems shown are the 4.2L Audi V8, as used in the B6 and B7 Audi S4 and other models.
How did you not know where you air intake was before crossing a deep river, common sense
Wasnt that the intake position was forgotton - it was the fact that the factory shrouding protecting the intakes was removed. In addition to going into the water simply too fast.
well the guy in the cayenne in front of him made it across. issue was FCP Ben entered the water too fast
@@chir0pter Still Nate Brown's fault though! :)
I’m curious about electric 4wds how are they going through water 😂
😬
Folks that drove through Rufford Ford tuning in lol.
Seems to be a thing haha
Stop ✋ a Land Rover Defender 110 or 90” old school would smash 💥 that off road even with a simple 300 Tdi
Should have removed the intercooler pipe from throttle body before starting the engine. Would have been fine.
Aaaand, THAT'S why you have a snorkel.
Moral of the video. Never buy an Audi or Porsche with a V8.
There's a place called Rufford Ford in England, which is becoming YT famous for killing cars, I imagine at least a few of the viewers of this video are doing so after destroying their engines there.
Not the first one to mention that Gerry! We are going to have to look that one up.
English speaking folks call hydro water
Hey! Those aren't Knipex pliers! HERETIC! 😆
Can't bring out the nice stuff for just a teardown 😂
@@fcpeuro I spent over $100 at Harbor Freight last night myself.
75% of this video is out of focus...
Engine got destroyed by stupid mistake
Too much talking.
who goes offroading in a cayenne? unreliable, expensive as fuck, parts hard to get. you guys have money to waste. but i was amazed how simple the mechanisms were compared to other german cars
Not a porsche A Volkswagen Audi engine
These guys exaggerate everything making it impossible to watch. Of course it’s gonna have water it in because it was drove into the river
Oh, well. It's just an ugly-assed Cayenne. No big loss.
at least my audi would have made it threw that river xD
Lets run em' back Kevin!
@@fcpeuro u wish
@@fcpeurowhat year is the engine
You make a video based on the fact that an idiot destroyed an engine? That is really weird!
If you arent learning from your mistakes in life - youre doing it wrong
@@fcpeuro hilarious joke of a response. Only an idiot would have taken that vehicle where he did. There is a real difference between stupidity and a mistake. That you defend your stupidity is a given.
