Today's subject is a 3.0L Supercharged V6 from a 2017 Jaguar F-Pace. This has only 62,000 miles and was pulled from a wrecked vehicle that was a theft recovery. Generally speaking, most people who drive stolen cars don't take the best care of them and that was the case here although some component failures were the main catalyst to this engine's demise.
This engine is a pretty interesting design as the block itself is a V8 casting shared from the 5.0L and 5.0L Supercharged JLR engine. Its the same overall casting, it simply does not have the rear most bores. The crankshaft has an area where there would normally be rod journals but instead it has a gear to drive some mini balance shafts. They did this to save money from having to design a completely new block casting. Was it worth it? I'm not sure. The 3.0 supercharged engines suffer the very same failures and have the same complexity as their 500hp 5.0L siblings but instead make 340hp.
Why am I doing this? I own and run a full service auto salvage business called Importapart. Part of our model involves buying core and blown up engines to tear down and salvage the good parts for resale. We do not rebuild engines, merely supply parts to those who do.
I really hope you enjoyed this teardown. As always I love all of the comments, feedback and even the criticism.
Catch you on the next one!

That gunk tells the entire story. This engine was destroyed because two incompatible coolants were mixed in the cooling system. Today's coolants are usually IAT (inorganic acid technology) or OAT (organic acid technology). They cannot be mixed together in an engine. What happens is they chemically react with each other to form a thick gel -- that goop you saw in this engine's cooling passages. I guarantee that if you had looked at the radiator from this engine, you would have seen the tubes in the core all clogged up with the same goop that was in the engine. I miss the good old days when engines were cast iron blocks with cast iron heads, and the coolant was just a 50/50 mix of ethylene glycol and distilled water with a little green dye added in.
I thought the same thing. Either that or Jaguar came up with a factory coolant even worse the Dexcool which also can turn to sludge even when only Dexcool is in the system. If the crossover pipe failed, and it overheated, it could be the crappy Jaguar factory coolant just couldn’t handle those temps especially on a boosted engine driven hard. With only 63K miles this likely still had the factory coolant and, unless leaking (a British engine leak coolant? Unheard of!), no coolant should have been added.
Regardless, everyone should use the correct coolant for their car and not mix coolants. Even if you don’t get sludge you can get premature head gasket failures and other expensive problems. Many of the famous Subaru head gasket failures were from owners being cheap and using generic “universal” green coolant instead of the $25 a gallon Subaru coolant. So they saved a few bucks on coolant and needed a $1500 head gasket replacement instead.
Yeah. Mixing coolant types is bad.
That's why if the coolant is not the factory color, I'd just flush the system with distilled water and put your own coolant in of your choice, personally shell rotella elc nf antifreeze in a 50 50 mixture with distilled water is what I use in my trucks and it's been great, far greater cooling than factory ford gold or whatever was in my truck haha
Does the gunk in the video really come from mixing the two coolants? I think it's mostly melted plastic in those passages
Somebody mixed coolants (OAT with regular) in a Land Rover engine I had (3000Tdi, 4 cylinder diesel, iron block, aluminium head) and it was a disaster. Corroded the radiator through in a couple of weeks and caused all manner of blockages resulting in overheating problems and warped head. Had to flush it all out, new rad, small coolant pipes unblocked manually, head skimmed, correct coolant fitted and it was all OK again.
I've watched your content for months. As a 65 year old mechanic, with 50 years of experience, I've constantly worried that you're working alone. If you would get pinched and be bleeding out, there is nobody there to watch you and know your status. Please don't ever work alone. I retired with ten fingers and two eyes. Wear your safety glasses. I'm here every Saturday night. You can never undo an injury. It's 4LIFE.
Worry much?
@@jedibusiness789 His worry paid off.
Good message

He's disassembling stuff, he's not playing with knives. You retired with ten fingers and two eyes not because you were super careful and had somebody watch over you, but because this isn't a dangerous job. It really isn't. Woodworkers, machinists and farmers get hurt, not mechanics.
A whole 8 hours just to get to a valve cover is crazy

It’s British. No more need be said.

There's gotta be another way to route that fuel line. Was it vacation time in the design dept. ?
I saw you at Cars and Coffee today. Your car looked great. I almost asked you what the tear down was but figured you wouldn’t have told me anyway. Keep up the good work! Saturday night tear downs are something I actually look forward to. 🇺🇸🇺🇸🇺🇸
A witches brew a little of this a little of that cooked at a very high temp 🎉
The designers really wrote up an 8 hour valve cover job in the service manual and the whole time they were doing it, it never even crossed their minds to just add another connector or put a hose in.
Is it weird that I find this oddly addictive? Each teardown is like a murder-mystery….although in 90% of cases, the murderer is always lack of oil….😂
oil=butler
I've done a ring job on an early 70's Maverick on an apartment complex parking lot and re-built my 289 Ford in my carport. These new engines just totally blow my mind.
As a former LRJ tech I was hoping you’d do one of these. This V6/V8 block is quite a thing.
Truly one of the engines of all time.
Yes. I’ve heard, compared to other engines, this one is also an engine.
I'm hoping he will do a 4.2L supercharged v8 from a jaguar or land rover.
Hopefully a buick rover v8 too. To see how simple engines were compared to rovers of today
@@antongutierrez9885 Buick 215/Rover V8 was produced in some form or fashion for 39 years, yet most people have no idea it ever existed
Just got all metal coolant pipes/parts including the rear crossover....so issues has been addressed by the aftermarket. The V6's in the F types have the new timing chain and as you note, they don't wear much....new motor oils (*and JLR spec oils) protect the timing chain way better (IL6a...).
Great video. Thanks. These are amazing engines....pulleys and a tune and 3.0L can do 475hp... Great engine....
That engine looks huge on the stand.
I think that’s what she said too!
It should be. It's a 3.0 AJ in the 5.0 AJ's trench coat.
You got to do a Mr. T dress up using all those timing chains you have removed! XD
I believe those torx looking heads are called triple squares, VW and Audi love using those things.
Triple square is 12 point. This one was 6. I'm guessing if it's not a standard torx bit then it might be a torx-plus.
You really have no idea how many people you have become a ritual for. The Saturday evening or the Sunday morning in bed show. I really like the show and it's nice to know that there are almost 250,000 people who like it too. Keep it up man, really. I believe this is a dream come true for you!
Greetings from the Netherlands
Those pistons were "well done" indeed 😆
The thing that impresses me most is the performance of the oil throughout the rest of the engine. The oil had to be over 500F.
It was FoMoCo oil I bet!! Better known as Wal-Mart 10/30.
"Drive it like you stole it"
and steal it like you drive it
Considering that the pistons look to have been magma balls for a while, it stayed together fairly well. I'd agree with the comments that the black bitumen looking gunk is some sort of stop leak product. It has no place in a modern engine for exactly that reason.
What you see in between cylinders is a plastic coolant separator. Plastic part that optimizes coolant stream around cylinders. Looks like it melted
I have an 3.0 S type and an S Type R, great to see jaguar stayed true to themself and made the newer AJ-V6 and AJ-V8 complicated to work on too 😂 But other European cars are also quite a hassel to work on... could be worse
Love when your streams show up in the UK, on a sunday a.m. Keep up the good work and been following you for a while now Eric..
I own an XE-S with this engine, which I've started doing the work on myself now that it's out of the free maintenance period. Very interesting video, thanks!
Same here love my XE the AJ126 sounds great for a v6
in ALL the engine teardowns i've watched you do over the last year or 2, I don't think I've EVER seen heads come off that easy, or head gaskets for that matter.
Certainly easier than the Audi V10's kinetic-release heads that explosively disassemble if you're not careful.
WhEn a head warps like that, it breaks the gasket seal. Not surprised at all that the heads nearly slid off by themselves.
Had the same experience with my 5.0 (head was warped)
The V6 is V8-sized, so it would act the same in a crash as the V8. This saves Jaguar a ton of money on vehicle engineering.
Maybe, but it's also a hell of a thing to have to engineer a smaller vehicle AROUND as a result. I'm imagining a Ford Modular V8 fashioned from the Modular V10's block and ancillaries...
@@SurelyYewJest In Germany, Zakspeed raced V8 Vipers which had V10 Viper engines with two of the cylinders blanked off after the rulemakers changed the rules to try to ban their Viper V10s (something about the capacity or number of cylinders, I don't quite remember).
I have a 2006 Lincoln LS with the Ford built variant of the AJ V8 and it's been dead reliable except for having to replace the plastic cooling system parts every 60-80k (yes, I only use the OEM Ford parts), it has 271k on it and is now my beater car for bad weather (it got hailed on real good a few years ago) if you keep up with the scheduled maintenance the AJ engines are usually quite reliable and will go for a long time without any issues; I am slightly surprised that an overheat got this engine as they should be a "failsafe" design (at least mine is) and should go into reduced power mode when the coolant is run out or over heats and alternately disables cylinders to provide a level of air cooling then again, car thieves probably don't stop driving (running from the cops) until the engine just flat out quits.
The AJ133 V8 and AJ126 V6 are NOT Ford engines! And they have zero in common with the AJ V8 derivative in your 2006 Lincoln.
@@kimjupe4532 I did not say that they were Ford engines just that mine was Ford built, but the AJ series of engines were designed when Ford owned Jaguar and even the current variants still have design elements from the original AJ engines if you look you can see that the cam caps are still marked with the FoMoCo logo. I have actually bought Jaguar parts for my Lincoln because the OEM Ford parts have been discontinued.
Dropping the subframe to remove a valve cover. Sweet mother of god
@@retiredbore378 Exactly. Design decisions are like going for a walk in the woods with a vague idea of where you are going. At some point, you know you made a mistake, but rather than going back and taking a different path, you try to cut back off track to get on the right track, but you get more lost, and make increasingly bad decisions. Jaguar (and Ford) have been doing this for years with some of their engines. It is interesting to see how complicated the minor 'fixes' become when 'start over' would have been the better choice. I am not restricting that criticism to just Jaguar and Ford. Other big auto makers have made similarly bad decisions (BMW certainly so). When you are standing there, looking at it, saying, 'Why? Why would any sane person design it like this?' You know that company is in big trouble, at least financially.
I would be shocked if a Jaguar didnt need that much work to do a simple job
Sadly they are all getting like this, something simple that used to be a hour or two has become damn near a engine out job.
@@trevornelmes9331 Not a mistake, people who own these kind of overpriced shitboxes trade them in on new ones every couple years, leaving any long term problems to the used car buyer and there neighborhood mechanic. Tax the rich.
@@seymoarsalvage Lots of them round here. The factory that makes the F Pace is half an hour up the road from me (I used to work there 40 years ago). There design, engineering and test (track) base is literally down the road from me, so we have Jaguars, Land Rovers and Aston Martins all over the place. Lotus have just moved to a site half a mile from me. Easy to afford if you work there and they give you one to drive home in. Makes my $4000 Kia look really cheap and nasty in the local supermarket parking lot (and it is, but, it never breaks down).
Those timing chain rails are the updates ones. The buttons you rubbed on are the difference. The old design doesn't have these and the tensioners eat into the diecast metal. The junk in the head is probably from the wrong coolant. Jaguar specifies a non-silicate coolant. Junk precipitates out with the wrong stuff. Since that was a 2 piece water pump, most came with 3 piece OEM so I suspect it was replaced and they used the wrong juice. Obviously, blew a head gasket and the blowby boliled out the coolant and melted the cross over. Love my 5 lter xkr, pushing 660 hp now.
love my 351c, 15 yrs, never touched it.. no computer, no tech, just hp.. only good jag, has an american engine fitted.. reliable..cheap.. ausie.. only problem with exotic, expensive cars, bmw,jag, lambo. ect. is they iether get pussy footed around, & blow up.. or thrashed by rtrds that cant drive.. then blow up.. to service my 351c costs $35.. hows yours.. i bought a salvage bmw, 3.0 tdi. just for the engine, for my 4x4.. have to fix bm,s mistakes..like all modern engines. dpf, egr, butterflies, turbo,s. most of the crap is only there, because of the greenies, & epa bs.. which, fks the engine, short life, so, is it really any good.. no..
Had a 70' Mach1 351 C, One of hte best muscle cars I had in the late 70's.@@harrywalker968
I have one of those 3.0l in my wife's XF. Wondered how robust the engine is as we bought it used. Now I am confident it is a keeper based on the level of engineering in the engine. It was clear that it was abused and it still held up for the most part. I agree that if it had used straight water or correct coolant it would still be cruising. Will be referring to this video if I ever need to tear it down for any repairs. I do need to pull the supercharger eventually to see about an intermittent weep at the y pipe behind oil filter adapter. Rumor is they are tough to pull but you made it look easy.
I cannot thank you enough for all the effort to record and prepare these videos. Best wishes man. Keep it up.
I have seen the plugged cooling holes before. If you look at the head gasket 29:43, the holes don't exist in the head gasket, hence the plugging. A good lesson in not using cooling system sealers though.
A good product used correctly can work well. Most of the cheaper ones are garbage though.
That engine is a LOT of fun in an F-Type. Wonderful sound, plenty of HP. It has a reputation of being able to handle plenty of boost. Just don't overheat them.
THAT OPEN DECK DESIGN IS TRASH FOR ANY KIND OF PERFORMANCE TUNING..IM SUPRISED THEY WERE ABLE TO THROW A ROOTS ON THEM AND LAST OUT THERE WARRANTY PERIOD. JAGUAR RELIABILITY AT ITS BEST.
@@beaches2mountains230yapping?
That engine is a trash jaguar is a trash, so is Range Rover
My 2019 jaguar needs an engine with 30,000 miles only
Whenever an engineer is tasked with designing these engines, they should be forced to perform service procedures on the preceding design with the engine installed in the car to learn not to make a valve cover job an 8 hour procedure 😂
"But everyone has the facilities to drop the engine out!"
@@miscbits6399 Let's make more profit for the shareholders and force the hand, it MUST be repaired at a stealership.
Such a perfect way to close out my Saturday. Always love watching these videos.
What amazing timing! I was going to ask for this stupid motor, it baffles me how they came upon the idea to reuse a v8 block for a v6... not even removing a row!
It fits in the same physical space with all the same bolt-ons in all the same places. Makes a lot of sense really for a manufacturer using an assembly line for a car that isnt going to sell in large numbers.
Jaguar are cheap! Then they put a supercharger on the V6 anyway, which really seems to defeat the point, lol. I'm sure there are good engineering reasons why they didn't just destroke the V8 to a 3.5L or 4.0L (or even 3.0L) for their entry-levels model, but they are not obvious.
I am betting that the gunk in the cooling system is "Bars Leak". Like they were trying to fix the blown head gasket :(
I'll bet you're right
I think you may have nailed it
Worked good on the miserable Brazilian 1.8L 4 in the ‘84 Sunbird, woefully underpowered for its 3840LB.
Good idea.
@@dalejorgensen46033800 lb Sunbird? That's a ton of options you added considering the original curb weight is list as 2400. And a 1984 Caprice wagon was around 3400.
Thanks for always reminding me to check my oil. It was very low. Now I'm back in the habit of checking all the things :D
How soothing to watch these teardowns and not be busting my own knuckles! Nice to see how all these are made so I know which cars I would buy and keep.
Thanks for all the awesome content. Happy Saturday night to all.
The Trophy 4 engine in the 1961-1963 Pontiac Tempest essentially started out as half of a 389. In fact, it's displacement is exactly half of the Trophy V8 389.
Was the same thing in the old Intl harvester v8 to its 4 banger i think dont quite me tho
Interesting to see the FoMoCo logo on the cams. I wonder, did the AJ series make it into any other cars that Ford made at the time other than Land Rovers? I am really looking forward to you tearing down an Audi V8 just to see the look on your face when you see what's under the timing covers!
They are made in a Ford factory. Leftover deal from the days when Ford owned them.
Thanks for another great video. I'm not into cars at all but I find your knowledge, enthusiasm and work ethic very enjoyable to see. Keep up the great work.
Speaking of weird block mods, I once owned a '64 International Scout with the 152 4 cyl. It was actually a V8 304 block (I think it may have been the same one in the older Jeeps), but one bank was essentially 'cut' off and a pan mounted over the hole. It still had the V8 crank, and the rod caps for the 4 cylinders were double wide to fit the whole journal. It was the oddest engine I have ever tore down.
Oh, why did I tear it down it? Well, because it broke one of those extra wide caps into 3 pieces, and ejected the center through the oil pan and made a really unique square hole in it.
Some more unrelated fun facts about that little truck (one of my favorite vehicles of all time), you can hold the 3 speed transmission in one hand. The low range on the transfer case, combined with the ridiculous granny 1st gear in the transmission was so low you could literally jam it into first gear and start moving without using the clutch. Good times.
My step father worked as a Sculptor on the first Scouts. Had some of the original sketches and shop pictures of them working on full scale clay mock ups. So called, Top secret project. He said IH built the Scout prototypes for a US Military contract. I suspect maybe the engine you speak of was used to meet a Mil spec. Long story short, Jeep won the military contract and the rest is history. IH went on to produce and sell the Scout commercially since all the heavy lifting was already done.
As always, great video plus I learn quite a bit from the comment section, thank you to everyone involved and watching. Oh, I long for the older days of simple engines and copper and brass radiators. I use to work in a Radiator shop and built many radiators. Much fun.
I've had several Radiators cleaned out at shops like your talking about, I liked watching them run the rods threw them and resoldering the ends back on, Ah the good Ole Days Lol
I’ve been a Jaguar fan since 64’ and it hurts to see some of the crap that they put out now! Love your videos! Out here from Menomonee Falls!
Where are the cleaned heads?
They’ve been putting out crap for over 40 years, this is nothing new. Still beautiful cars tho
YES! MY REQUEST FULLFILLED! Thank you!
For a massive overheat it looked pretty decent internally.👍
Naw those cylinders are trashed. Needs a complete resleeve, or toss the block.
was expecting melted metal
It's incredibly easy to build a V6 from an existing V8. Jaguar, as shown in this video, doesn't even bother changing the outside dimensions of its block. The company's V6, was simply its V8 with shorter cylinder heads and balancing weights on the crankshaft where the last two piston throws should beLike all V8-derived V6s, Jaguar's has a 90-degree angle between its cylinder banks. That works well for a V8, but it's the wrong angle for a six, because it means the engine will fire at uneven intervals, and odd-fire engines run rough and make terrible noises. A V6 will fire at perfectly spaced intervals (read: smoothly) with its banks splayed to 120 degrees, but that's too wide to fit in most cars. Halving that angle keeps the even firing order and, with a couple of crank counterweights, it allows for smooth running. Toyota's 3.5-liter V-6 is a 60, and it's very smooth.
But a 60-degree six negates the economic advantage of basing the engine off an existing V8. So manufacturer tend to stick with the 90-degree architecture and apply various tricks to make it work for a V6. The big one is using split, offset crankpins. In essence, they slightly offset opposing pistons, forcing them to move in such a way that the engine fires evenly. But these are difficult to engineer and expensive to manufacture. Plus, the 90-degree V6 usually has an engine-driven balance shaft to prevent the whole complicated mess from vibrating itself apart. All of this adds expense and hurts efficiency. That is why many European manufactures. Have resurrected the straight-six engine(BMW did never stop making them as an aside). Accountants want fewer cylinders. The engineers want smooth engines. The compromise? A good straight six. Each of its cylinders has a twin that's doing the opposite thing, at the same time and in the same plane, canceling out the other's forces. That lack of internal dissonance gives perfect balance.
I rebuilt one of those a month ago. It was $9000 for 4 VVT gears, 2 timing chain, 4 buffers, 2 tensioners and all the gaskets to put it back together. 22 hours of labor too 😮

Again Thank You Eric another Great Tear Down, another Saturday night in the books...
Your voice overs are the best. You didn't even have to use any penetrator on this one. It's definitely time to cram the cam caps loose.
𝗣𝗘𝗡𝗘𝗧𝗥𝗔𝗧𝗢𝗥
Watching all your tear downs greatly increases in my comfort level in my maintenance schedule on my own cars. As well as reinforcing what I am and am not comfortable doing repair wise. And I may have changed opinions about what cars (and engines) I’ll buy in the future.
And yes please to the Mercedes video. And maybe a future VW VR6 engine tear down. Always been curious about those. Or the W12 that’s two married together.
Agree about the VR6, and about learning engines to stay away from.
Okay, you commented on the timing chain off this engine. I've been going back and rewatching some of your older tear downs and you often comment on the chains when they come off. IN one video you even said the chain would make a great addition to your collection. You've done a lot of tear downs now so let's see this chain collection
Had this engine in an XF, put 180k miles on it, was a releable engine for the most part, the coolant crossover pipe started dripping so had that changed but other than that it was fine.
How old though?

GOTTA BE a 'head gasket seal in a bottle' with the clog. Look for it next to the "power steering stop leak" and my brother-in-law...and all the other things that don't work!!!
As always I watch your program every Sunday morning. I have worked in the tool and die industry all my life as a machine repairman. I have come to a final conclusion this morning. What I see and have seen in my life is this. The old school bench leader on projects always looked over prints before a build, the really good ones, German by the way, would see problems and March that print book up to design, and they would raise hell with those newbies and have it corrected before building said project. I don't think we have that anymore. It's either that or what I have said before, which is they are all on acid trips when they think of this crap.
It's not "acid trips".
These days companies are run by accountants and MBD types. All they care about is making money for the shareholders. So corners will be cut, engineers will be overruled, and so on and so on.
And the irony is this vehicle costs more than an apartment in my country, only the rich or those extremely dumb (but with the influencer mindset) to spend their entire paycheck on repayments will buy these vehicles. Oh and in 2017 they aggressively advertised the vehicle this engine is from, here, in my country.
This was a very interesting teardown to me as I have owned 2 versions of the earlier version of this engine, a 2005 Mercury Montego and currently a 2004 S type Jaguar. The Merc always felt underpowered but the Jag is fine. It also runs smoother and quieter and even gets better gas mileage. At 56,000 miles its only weakness is the PCV system, which looks good but is terrible. A Steeda oil separator made a huuge difference in how it runs. Would like to see you do one of those Ford/Jaguar 3.0 v6s.
Neither of those cars used a 'true' AJ engine. Both vehicles used the 3.0 Duratec V6, which is a 60° design and had some input from Porsche in the design.
i'm not even a car guy or really interested in cars in any way but i can't stop watching these
Love these teardowns and the sarcasm.
Thanks for keeping me entertained on my train ride.
I've always thought these were the most logically insane things I have ever seen.
"Stolen" - yeah, right. My bet is on the owner not paying attention to the light (long time JLR owners are trained to ignore electrical gremlins), overheated the engine, drove it on its last legs to the bad side of town, and reported it stolen.
I'm sure the owner just misunderstood what the mechanic was saying when he said it's time to "put it out to pasture". They totally didn't expect it to get stolen! No way!
Man,that hollow metallic head bolt removing popping goes right thru me every time !!💥💥
Thanks for this particular tear down!
That stuff clogging the coolant passages could be some kind of stop a leak product..my guess
Why would a thief in a stolen car worry about coolant leaks and issues when Trooper Byrd is hot on his sorry a$$? 😂
@@emilschw8924 did you miss the melted coolant crossover missing chunks out of it? unless they rode around on the limiter for 5 days straight i dont think that amount of build up happened over one chase. early signs of overheating, owner put in the aluminum stop leak made by bars, took it into service eventually where it was stolen from some shady repair shop
This is exactly what I thought it was. Stop leak. Seen enough of it in my 21 years servicing cars.
@@emilschw8924Never underestimate what a thief is capable of. Years ago, I had a vehicle stolen, and the person who stole it used it as their personal vehicle for months. Even put new floor mats and seat covers in it.😂
I got the CAD data for this engine many years ago to look at exhaust manifold design (I worked for the supplier) and couldn't believe the use of the V8 block for the V6! I asked why but the JLR boys were saying nothing! I drew my own conclusion (cost) which seems to be the case.
afaiu it was to offer a V6 without having to do crash tests with a new engine
Eric superfan here 🙄🙄🙄
I was one of those kids who took EVERYTHING apart to see how things worked... Most times I could get it back together (mostly)
My uncle back in the day asked me to help him tear down a automatic transmission just to see what was going on inside and I was amazed by all the check ball's and channels.
I've been an ironworker for 30+ years and have always had a new 1 ton Silverado (diesel) and have always been amazed by the automatic transmissions that can transfer all the power and torque from the motor to the rear wheels (magical 🎉). Pulling load's that may or may not been WAAY over the rated capacity... I absolutely love this channel and am jealous of your job!
Yes. The 380hp V6 in my F-Type is plenty powerful, and i can get better than 30 mpg. Thanks for the tear down!
So many makers use plastic cooling system components and they never-ever learn.
by design, cheap to make, expensive to replace - job creation
Loving the content as usual...
That's a garbage idea having the V6 the same size as the V8.
Would love to know what the sludge is, haven't seen that before!
And looking forward to the video on the Benz!
Those heads are and pistons are TORCHED!!!!!!!!!!!!!
Also my favorite part of Saturday evening
What an utterly bizarre engine design. Thanks for the great teardown, as always.
This engine is awesome. Ivhave one in my '16 LR4. The thing about those vehicles and other LR products this engine is in, is that most of them are unibody-on-frame construction. Ina those cases, sometimes its faster to lift the body off the frame to do the tricky repairs. You cant do that on the Jaguars.
Cool engine this week! Love your videos! Still hoping you can tear down a 1.8 out of a 2016 Chevy Sonic, and a 2.4 SRT4 engine out of a 2003 PT Cruiser GT that has the aluminum intake setup on it. As usual another great video!
too bad the PT we have dead in the driveway isn't a GT, I'd have loved to donate it since A GT was my first car and my dad had two
It is a cool engine. Although, it didn't stay cool. That was obvious.
The Merc 112 is a shortened 113. I have a 112 in my old w208 CLK320. Great engine!
Great video - thanks!
Another great video Eric!! I have seen many used pistons in my life but never a matched set of 6 looking fresh out of a powder coating booth...the heat to bbq them like that...wow!!
As for that line to be pulled before the valve cover...yet another way a car mfr has made it so one has to go to a dealer or make specific shop...8 hours...why not have made another union in the top edge of the head area...ughhh...
Keep up the great videos Eric!!
I said this in a previous IDC video: I am utterly surprised that GM didn't do this for the 4.3 V6.
The 4.3 is a 350 small block with two of the center cylinders removed. They didn't ACTUALLY cut a V8 block up and weld it at the engine plant, what they did was to use CAD/CAM tools to design a new casting with 6 holes instead of 8. This is advantageous because the boring machines and assembly machinery used to produce the V8 can produce a V6 instead with the push of a button, saving hundreds of millions of dollars in expense for new tooling for a totally new design. It makes sense.
But it seems to me that it would make more "GM Sense", since GM's engineering department's main goal is to SAVE COSTS WHEREVER POSSIBLE AND STILL MAKE THE CAR SELLABLE TO GULLIBLE BUYERS, to simply put V6 guts in a V8 engine. Just the way that "Jag-You-Are" has done.
[Technically, the pronunciation of the name of the central American animal is "Jag-WAAR", in the indigenous language]
You can easily do this. Build a V6 crankshaft with a shaft on the end where the rear pair of cylinders would be. And do the same with the cams. And the heads would have nothing after the third row of cylinders, just a flat blanking off plate where the valves would be. There would be a fourth pair of bores, but they simply wouldn't be used, just a pair of holes.
The great part about this? If you had the crummy V6 version, you could get a crank, cam, pistons and heads along with an intake from a junkyard engine and on the cheap upgrade to a V8~!
My point is that I don't know why the skin-flint automaker GM didn't do what Jaguar did~
Great video!
They share a couple of the same dimensions but it is a completely different engine with a balance shaft
@@justinpeterson6839They share a lot of the bolt-on components, too.
There was a race car that had done jaut that, but the opposite. Used a 5.7L and disabled two holes. Basically, turned it into a 4.3... I believe it had to do with the rules, stating 6 cyclinders... kind of cool.
@@IceBergGeo YES! I heard about that, but I cannot find it. And while it is different, there are people who take 350's and build a racing V4 out of them, some sort of short track racing where you don't care how badly the engine vibrates. 👍
All those jag you ars need to be calling them Ford Co you gars for consistency. Over here, it's a jagwar.
The gunk was a sealer of some sort - someone tried a pour-in product to fix the blown head gasket issue and just kept doing more and more, eventually plugging up the passages. Block is toast.
I hope the analytics show when I liked the video! Thanks for the pause and narrative.
The Autopian had a write up of this engine recently. Among the costs saved by having the V6 and V8 having the same dimensions and mounting points are crash testing, chassis engineering because they use the same front subframe and production tooling because the fixtures for machining blcks and installing engines are common. It looks silly but the accountants and engineering managers loved it.
Great vid sir. That sludge stuff in the coolant jackets would be a nightmare to flush out in car.
It's a good thing it got stolen so the owner doesn't have to deal with the expense of fixing the damage caused by a neglected cooling system.
I love it when a blower has "nice lobes".
Yeah, but it's got a loose coupling.
@@PSUQDPICHQIEIWC - That's what she said.
as a card carrying member of the gambler 500 operators union I am very glad to see that Jaguar has thoughtfully provided us with very convenient foil wrapped burrito warming sockets at the back of each cylinder bank on the keep-up-with-the-joneses spec Jaguar engine shown here.
edit: that sludgy black fibrous material in the water jacket holes in the head is the remains of various GFRP cooling system components. The inside of that crossover tube with the two bonus holes melted in it, the end tanks of the radiator, any plastic tees in the cooling system, etc etc etc. When you burn a head gasket that badly and then continue driving it in anger, you are pumping pressurized exhaust straight into the water jacket and it can make it a surprising distance before it cools down. I have seen it make it all the way through a Subaru to the radiator cap area and literally melt notches through the seat that the radiator cap pressure regulator plunger pushes against, then release the pressurized exhaust/coolant mix straight into the overflow tank and explosively vent the entire cooling system out of the overflow tank cap (which was blown open) in a matter of seconds. It was really quite impressive. I had to replace the radiator as well as the engine.
I bet there is a substantial amount of carbon in that blackish sludge as well from incomplete combustion.
Thanks Eric, nice work.
I'm trying to do the rear coolant crossover manifold in my 5.0 V8 XJ with the engine in the car. It's not too difficult but needs a lot of dismantling, such as intake manifold, window wipers, scuttle panel... all for access. I still can't get at the 2 T30 bolts on the manifold that sit towards the outside of the engine. Searching for a tool that will get the job done. Your videos (on both the V6 and V8) help me understand what I'm up against! Thanks
Love these videos ❤
Love your Video's and I have learned a Bunch, I was Shocked on this Jaguar Engine when I realized it was a FoMoCo engine I never knew Ford was involved with Jaguar.
Great tear down, I enjoyed it! This 3.0L SCV6 rides pretty good in my 2016 LR4! I just upgraded the front cross-over and Y plastic coolant pipe for aluminium ones (made in china but still they won't be cooking in there). I'll do the same upgrade with the rear cross-over pipe soon. The guides and tensioner upgrades I think fixed the timing chain issue in 2014 and I also think they upgraded the chain (not sure about that). However at the same time, they added the ECO stop-start so that can't help those poor chains, I'm sure. That's the reason my ECO mode is always disabled. I bet the gunk is incompatible coolant or some coolant gasket sealer that was not used properly (not flushed). It'd be funny to ask the thieves ;o) Thanks for the video and Cheers!
27:33 I am guessing that since the engine got so hot, the top of each cylinder warped. If you measured for roundness on each cylinder, they are oval shaped at the top.
Someone keyed my guitar teacher's car last night.
Fortunately, the damage seems to B Minor.
Nice lol
*groan*
Was this an act of Augmented or Sustained damage.😂
For anyone wondering. The VW/Audi Head stud bits he is using are called Triple Square. They look like torx bits but the main bit has more meat to it. Its 3 offset squares to form the head of the bit. Torx are more like a Spline. Whatever you do, don't cheap out of these. You need to get out the axles and all sorts of stuff on VAG cars. Anything with Triple Square is there to warn the technician that the bolt is single use only and must be replaced.
I'm amazed at the level of tech in a daily driver, aluminum block, heads, fuel injected, supercharged, double overhead cams, on and on!
Nice, always wondered about these.
Looks VERY similar to the land rover supercharged engine with supercharger and integrated charge cooler. I rebuilt a similarly overheated engine twice, once was fine.
I've been waiting for a teardown on one of these; such a bizarre engineering decision to make a V6 out of a V8 by just not boring out the rear two cylinders, especially coming from a "luxury" brand. That would be like BMW making an inline 5 out of a B58 without shortening the block.
As an engineer, having to go through the requisite motions to bring such an obvious bean counter design into production would permanently hurt my soul. I feel serious sympathy for Jaguar engineers.
Maserati did it for the Citroen SM but at least they lopped off the block and the crankshaft. Not a terribly good result though!
@@meanderinoranges engineers have souls? i thought the sole purpose of an engineer was to piss off the mechanics........... That comes from seeing so many ignorant designs both on cars and generators. It makes me wonder if a mechanic stole an engineers wife and this is the crap we have to deal with now.
@@georgetinc9578 do you think engineers are really so stupid that they don't know they're designing engines that are difficult to maintain? Engineers know EXACTLY how difficult their designs are to work on. But the problem is that cost is king. Engineers are slaves to the bottom line. And that's what forces their hands 99% of the time.
@@meanderinoranges We all know that relative to nearly all major manufacturers, JLR have the engineering budget of about 50 pence, so really the fact they managed to make such an amazing engine at the end of it is really quite something.
First time on this channel, brilliant video shared on the F-type UK forum. We got a lot of F-type running these engines here. I got a 2018 with 25K miles and it's runs extremely well. I much prefer the V6 to the V8 in my application (daily driver).
realy love all your videos it allways amazing to see what prolonged oil changes annd hard driving does to engines, keep the videos coming ps have you ever done or thinking of doing a 2015/2020 2.0 hyundai diesel tear down
"torx bit but not a torx bit"
Triple square?
edit: Yep, triple square. I got a set of those at Northern Tool a few months ago.
I could listen to the pop of pulling the plug leads all day. Sorry, know that's not useful.
really enjoing your videos! you rock! and it really is the best qualities of youtube! Legend!
Yippieh!!!!! M113K coming up! Shouts from Cologne/Germany
Maybe i'm just used to a basic double overhead cam engine or a pushrod engine but this seems unnecessarily complex. I've ridden in a Supercharged V6 F-type and they certainly do have some torque.
With using same block between the two motors id say the reasons they did it this way would be so they didnt have to re engineer everything when they put it in so everything bolts up/mounts up in the same position which makes sense
If they had shortened the block everything would need to be re engineered to work so from a production stand point one size fits all
Eric,
Great video - thank you.

My favorite engine for longevity and acceptable power is Buick V8 with two cylinders removed from the middle...Buick 3.8L (odd-fire) throught the L32/L67 gen III 3800's. Done well, it tends to be a really good thing and most the manufacturing process/tools remain the same.
