From the bottom of my heart thank you for not LS swapping this car. I worked at a JLR dealership for 5 years and know the sound and look of F-Types well and I love them! Personally haven't seen many broken down ones, but thanks for restoring this one to its former glory!!!

I agree, a transplant makes much more sense than a questionable rebuild. Early November 2020 my 2012 Accord V6 engine with VCM failed due to the VCM system failing. According to my mechanic, valves were jammed open, interference engine, bam. Bent valves, bent connecting rods, scored crank. All this despite excellent maintenance. So, I went for a transplant. Ended up with an engine with 50,000 less miles and peace of mind, VCM disabled.
The one thing everyone should do is at the first service retorque the heads. Especially on an all alloy engine. Manufacturers used to put that in as a requirement and would void the warranty if it wasn’t done. But like lifetime fluids they have worked out that the warranty will expire before the components fail and are actually encouraging poor maintenance practices to ensure that the vehicles die an early death.

By the way retorque means in this context checking that the wrench clicks at the correct torque setting without turning the fasteners. If they turn more than a fraction you toss them out as they have probably failed. If the gasket hasn’t blown you can replace them one at a time following the factory sequence.

Ages ago my dad's VW rabbit got really hot and it was never right after that, they believed the head warped on it. Six years old at that point. Aluminum head. But what had happened was 300 miles from home the cat element fell apart, causing an exhaust restriction, and all we knew in the car was it got hot. It was 12 year old me who pointed out we'd just passed a shop with a row of VWs next to it to go back to and have it looked at. They put a straight pipe in to get us home.
Just a note about head gaskets on these. I know of another person on TH-cam who said they have had trouble with head gasket leaking after replacement. A lot of the issue lies with aftermarket gaskets. When I pulled a head gasket on a customers vehicle it was MLS like any other MLS gasket.

As someone that’s rebuild numerous V8 engines in my lifetime, I have a hard time understanding what exactly is the problem is with this motor. Before I went out and spent a large amount of money on another used engine, I would be inclined to put the current motor on an engine stand and tear it down to see with my own eyes exactly what went wrong. If in fact it is/was a blown head gasket, I would send the heads to a machine shop and have them decked and then check the block top for squareness before any new head gaskets were installed. If there's a problem in the cylinders, then it's a complete teardown and rebuild of the engine as the only option, or junking the motor and purchasing a used one like you did. Unless the prices have skyrocketed for machine shop work, this may be a less costly solution. The last machine work I had done on a Ford 428 about twenty years ago cost about $2000.00 and this included all new pistons, bearings, cam, complete valve job with hardened seats and re-sleeving one cylinder. That was just for the machine work, I had to reassembly the engine. Which I always enjoyed.
What I've heard is the block actually gets damaged. The edge of the cylinder walls are thin and chip, the block warps, or the block cracks in worse case scenarios. I guess a reman engine is close to the cost of rebuilding an engine in that condition.

I don’t rebuild engines I get a long block or a engine from lkq. Exception to the rule is my 67 mustang convertible! That original 289 is getting rebuilt.
I've had my temp light come on and I pulled over and let it cool down to find out my fan went bad. I replaced the fan after driving it home after it cooled as I was about a mile from home and didn't trust driving it when it was over heating. It's not worth the cost of an engine when you can pull over and ether have it towed or let it cool down if you don't have far to go. But then again I am in my mid 40's and know better then to push it.
Damn, I was hoping to see the old engine rebuilt 😢 Understand the timing/cost involved. Reminds me of BMW fiberglass valve cover - no warranty on gasket replacement
Aaah the good old BMW fiberglass impregnated plastic valve cover. Changed a few of those in my time. Yes once they get hot enough or go through enought heat cycles they twist and distort and then they will never seal. I would imagine the alloy block on this Jaguar is the same.
@@TheMrLebaron its mostly the same with modern American sourced engines as well. They really are engineered as one time assembly type systems (Nika/Alu-sil or plasma metal arc transfer in the bores, open top cylinder decks, non bearing equipped cam journals etc.) If you are building a total frankenstein mad science project you can still make a go of it, but its so not a daily driver type of project unless your both brilliant and desperate
If you go back to ChrisFix's head gasket seal video, he's got an older 3.0 Jag engine and after sealing the engine it got about 10,000 miles down the road before he tore it down and showed that a) the head gasket sealer "worked" and b) the block itself was warped, so changing the head gasket would not have actually fixed the problem, because the gasket was actually fine.
im kinda shocked that your surrounding doesnt know how to check engine that blew headgasket. If block straight and head resurfaced, no cracks, itll be perfectly fine. Also you may go for better gaskets that will be more durable and wont suffer that much. Most likely those engines are prone to failure because of temperatures and heat overstressing.
Yep. It's not a guessing game of putting in a new gasket and see if it will hold. Measure all the tolerances and if there is damage to the head or the block you have to fix these, for example by laser welding.
Strange that they let go months later, must not check the heads? Might go soft after overheating, but you spend 5 mins and check that on a mitsubishi engine so why not a $10000 one
@@minimeee04 oh yeah, so they just do the heads and back on. A shame, testing blocks is pretty standard stuff, cheap compared to the labour of pulling the engine in and out
Better do head studs and new head gaskets before installing the replacement engine while its out.Spunds like a clamping force issue and will definitely happen to the replacement so at least do arp head studs before installing
Hey man, great video. I have a 2017 Jaguar F-type s with a bad engine also. I found a similar engine off an XF model but not sure if the performance will be the same. I heard the engines are the and just the pcm tuning is different. Any thoughts?
Hi I love your videos I have a question I'm doing an engine swap just like you did but the donor's engine its missing one sensor behind the a/c compressor and I've no idea what's for
Why not FCP euro for gaskets?? I'm having a nightmare trying to get a buick 3800 S/C running right. Wish I'd kept the jag with the ford 3.0D. Only problem I ever had with that was an alternator. I did a lot of work on the jag, but all as preventative (cambelt, trans mech overhaul, etc.). Didn't have to guess if it was metric or imperial, or drain the block through a buried knock sensor. Completely agree on buying new engine for the f-type. Alloy motor that's been cooked - that's a big gamble.
I thought you were being overly critical on this car when watching the first round of videos but the more indepth into this repair you get the more it seems warranted. I thought my SHO repairs were a bit much, PTO, Timing chain Waterpump, but they're a cake walk compared with the this monstrosity. Shame, I always wanted one of these cars.
That sensor is part number F666, it is the KTEG sensor...Kiss The Engine Goodby for the next time it blows up. They decided it happens so often it was worth letting you know. There is a corresponding light on the dash, a toilet bowl with circling water going down the drain.
Just saw a salvage jag close to me in Richmond, Va on FB marketplace. Too bad it is so far away, would have been a great parts car. Only wanted 9k, states the vehicle still starts and runs.
I was at a Sonic yesterday, and I pulled up next to a Nissan Armada. The lady started it up. The thing sounded horrible, and water poured out the exhaust and died. It took her several tries to get it started and then she happily drove off spewing smoke and steam, so yeah some people drive until thoroughly dead.
To me Jaguar's are some of the most attractive cars on the road, but you have convinced me that I never want to own one. I know you said that an LS swap would be too much work but it looks like it would have been worth it and you would have had a better car when you were finished. It seems that an LS Jaguar would be a lot more desirable and therefore more valuable.
I believe FCP Euro carry spares for JLR cars, should give them a call it will be much cheaper than the dealer. That is if they have the parts as there is a delay on a lot of parts worldwide.
That new engine must have been dogged out or opened up for it to have valve cover gasket leaks at 34k miles. Hope you have a vin from donor car to verify mileage. They don’t leak that often at all.
Fix vs replace has its moments. Had a disagreement with my manager over replacing an element engine vs having the cyl head repaired (broken valve, common when valve adjust is ignored) he wanted an engine put in. I wanted to repair. Luckily the customer chose my route, especially considering it was a solid 1200 less.
The moral of this story isn't "don't buy a Jag" but "don't buy a cheap Jag that's been abused and you have no clue about its history". Treat 'em properly and they're no less reliable than any other make. I'm on my fourth and none of them has ever let me down. Petrol and tyres, that's all they need!
When I saw the first video of the car sitting in a junkyard, it was kind of a dead giveaway this thing wasn't worth resurrecting. I suspect it has more than 34,000 miles on it, or the previous owners were total boneheads.
2:39 -- I know this sort of situation. Though Its more to do with the people who run their gas tank down to the very last pipper between fill ups then cry about it when they are on the highway or in the middle of nowhere, run out of gas and are left stranded. My dad never let his car drop below half a tank if he could help it. He always said that he keeps it topped up as often as he can just in case the worst happens and you need to go somewhere... And the worst did happen. Because There were multiple nationwide fuel shortages and while people were out there queuing 3hrs for fuel then fighting with people while at the pump. My dad was able to avoid this completely till the gas stations slowly managed to get their fuel supply back up. Then we queued 30mins for fuel and that was that.
These cars are JUNKY POS'. We are sick and tired of JLR coolant and timing issues. We do a ton of this crap. We have built a parts list as a kit for when they come to our shop. The customer options are to fix all coolant pipes and hose or take it somewhere else. We are the only euro shop between Dallas, Houston and Shreveport that will work on them. Just shit...
from my experience the 4.2 and with new thermostat and coolant upgrade are pretty bulletproof right? do you have lots of problems with those on a wider scale
Good to get some real life perspective on these cars. I am too knee deep in German POS's to ever work on one of these. Though I did work on pre-Ford Jags and that was enough to say "never again". I figure any company that is too stingy to cast a separate V6/V8 block has probably cut some serious corners overall.
@@slasher9883 again, personal experience, but I have both a 99 xk8 and an 08 xk, both have been exceptionally reliable, I have put 11k miles in near a year on the xk8 in daily use and traffic, no issues apart from alternator dying at the end of its normal span, these ford period cars really are solid when preventively maintained. peak years are 1993-2009, I would not buy the later direct injection over complicated tata cars with timing chain issues
I’d be a little more concerned than you appear to be about that Milwaukee throwing it’s chain all the time. It’s not a very powerful saw, but still that’s not a bracelet you want to wear. Could be related to the lack of oil. A quick squirt with whatever fluid you have in a can would help if it’s just one or two quick cuts, chain is probably already stretched and trash though.
Just curious how much more it would have been for the V8? I know you said it would need a wiring harness swap, but hey if you're in for a penny, in for a pound.
Underdrive Supercharger pulley probably contributed to engine blowing up. Seems like these are Ford engines already overstressed for more performance by Jaguar. I would leave stock pulley.
@@timk.537 extra boost can blow out headgaskets, then car overheats. Simple. Its spinning the supercharger faster to make more boost than stock. I have 2 supercharged cars for years. Also have a Jaguar XJL 2014 that I did timing chain and tensioner myself and everything inside the engine said ford on it. Probably why the hose routing is so crazy, making something fit several cars, like that water pump with the plastic outlet that always leaks, changed twice on my Jaguar myself. I still love the cars though. They just quirky.
@@racerx94 First, the supercharger pulley isn't an issue at all. This is a 1320 Eaton supercharger and your 2014 wasn't using the same model despite being the same engine on a differnt tune.. It's well known that this 126 engine can take considerably more boost, which is not achieved through the supercharger pulley, but by increasing the size of lower crank pulley. This model is rated at 380hp and 330ft lbs where many F-Type owners modify to run 450hp and 430ft lbs for years, with no issues at all. The designers at JLR claimed the engine can take up to 700 hp but producing those numbers would require a total overall. Still, these engines very rarely fail. Again though, it's not a Ford nor has it ever been. This aj136 and the 5.0L Aj133 that this is derived from are not Ford designed. Feel free to read up on this from a reliable source outside this ill informed comment section. It's very well documented. Yes there are some Ford parts but this happens in every company that was once associated..every single one. That does not mean that Ford designed or manufactured the actual engine.
You would probably need to get the block, pistons and head machined on both banks to be sure. No doubt you'd need to change all the shells, gaskets and timing chains which means you'd in for £10k at a minimum. Barum engines (on you tube) recently did something similar on the earlier model and it's an expensive repair.
The more I watch the excrement that you have to go through to keep these modern engines running, the more I appreciate the OM615 and OM636 that I worked on. Narragansett Bay.
@@TheMrLebaron you obviously missed the joke, maybe my sarcasm was a bit too subtle for you. The comment was not about Watch JR Go at all but about know it all’s in the TH-cam comments. But thanks for your reply, sorry you didn’t get the joke.
The Jaguar 3.0s aren't problematic, they're cut down Jaguar designed V8s. No Ford input to the design apart from paying the wages of the Jaguar engineers at the time.
Another one.. The 3.0L aren't problematic. Where are you getting that from? Think about why they were used so much in so many different models over such a long time span. How would that make sense for any manufacturer, anywhere, to do that?
It's the thingymajig sensor, which measure the dooveywhacker position and the whooseywhatsit temperature. Dam JR I can't believe you didn't know that? .......lol
I'm confused. If the engine overheats, it's a waste of time replacing HGs. Would that be a problem on your "new" engine too if you pre-emptively change them now, ie it would still fail in 4K mi? Seems like now would be the time to change the HGs - good engine and it's out. Then you should be good for another 30K mi. Putting this "new" engine in with 30K mi already on it sounds like a matter of when it fails, not if.
i was thinking the same thing....what is the point of putting in a different engine without changing the part that failed on this new engine...especially if both engines are the same in mileage?? this new engine is just a ticking time bomb.
Head gaskets are a “no problem, no pull” type of part. You can count on an immediate failure on 20-30% of new gaskets, even if you do everything right.
@@glassvial he also said in an earlier video, and again hinted at it in this video, that these engines are known for a high failure rate and that there is a company, i think he said in California, that tears the engine down and essentially makes it bullet proof with new/improved parts to prevent the common failure. so if JR isn't doing this, he's essentially just putting in a used engine that will fail sooner than later.
Solid choice, spending all that time and money to replace the head gasket. It is a gamble, and you seem to understand what your time is worth. Thanks for bringing us along. What is engine worth as a core?
is the sensor for the oil level? If you are changing the engine why not fit the 3.0L diesel as a project? you'd get near 50mpg + in that body shell. Still around 300HP and a cool body shape...
I have the opposite problem with my Ryobi 18V saw.... The oiler works 100% of the time. It's just a gravity fed tank. 😂 Whatever. Still dang handy to just grip it and rip it when you need to knock of branch or two down.
Just scrolled through to see if anyone else posted the same comment. My Ryobi 40v saw has been excellent, so far. Hasn't thrown its chain once, and the oiler works every time... heh
@@tortron valve sticking open and burning the head because the aftermarket valve seals swell up causing them to stick. the man i got the car off of had the head redone before i got it because he overheated it
I did seriously consider the F type and I still think it is one of the best looking cars on the road today, but seriously why did Jaguar make this an almost impossible car to work on! Nonetheless, still looking forward to seeing it run again and hopefully with a careful owner it will give trouble free service for many years to come.
just because there is a head gasket leak doesn't mean the engine overheated and is trash....right? thought it ran ok in earlier video besides the gasket leak
my mechanic is fond of saying, head gasket failure is typically sign of a poorly maintained cooling system. so, replace and flush your coolant regularly
Here's what I've learned from your channel and other similar channels. Stay away from "high end" cars. The only thing high end about them is the price tag for repairs and upkeep.
I'd mess with the Supercharged straight 6 in the XJR , but I don't think I'd even mess with this one, as adventurous as I am.. There's an engine rebuilders channel from the UK called Barum Engines, and he doesn't even want to mess with these engines, he tells potential clients to price a new engine as the amount of hours that would go into a rebuild would get close to what the OEM would charge for a replacement engine. And as luck would have it most of the time, you do the work and then the car comes back in a few thousand miles with a failure or noise in the engine, its just not worth it with these over-engineered engines (try that for a mouthfull!)
My 2014 F Type S failed as well :( ... what kind of price would I expect to pay on just the labor to take the old one out and put new one in? Not including the price of the engine. I will source a used one. Thanks

I was hoping for a Tapa stage engine, but I respect this. Hard to pass up in town and a year warranty.
Well, was about to go to bed, but I can wait 15 minutes... LOL
Same ! Haha
I guess it's a timing sensor that also helps in giving accurate position of the crank and cam shaft for better performance
If it's indeed the crank sensor, nevermind better performance, it won't even run without it
I thought it was “ it’s gonna break real soon” sensor. 😂
I've had my temp light come on and I pulled over and let it cool down to find out my fan went bad. I replaced the fan after driving it home after it cooled as I was about a mile from home and didn't trust driving it when it was over heating. It's not worth the cost of an engine when you can pull over and ether have it towed or let it cool down if you don't have far to go. But then again I am in my mid 40's and know better then to push it.
Damn, I was hoping to see the old engine rebuilt 😢 Understand the timing/cost involved. Reminds me of BMW fiberglass valve cover - no warranty on gasket replacement
Its not worth it to rebuild these. Its not a 70s Chevy 350, theyre WAYYYYYYYYYYYY more complicated
@@TheMrLebaron Yes JR basically said once it over heats almost anything and everything could be affected.
Aaah the good old BMW fiberglass impregnated plastic valve cover. Changed a few of those in my time. Yes once they get hot enough or go through enought heat cycles they twist and distort and then they will never seal. I would imagine the alloy block on this Jaguar is the same.
@@ztifbob Its exactly true, modern engines make so much power for their size you cant trust it
@@TheMrLebaron its mostly the same with modern American sourced engines as well. They really are engineered as one time assembly type systems (Nika/Alu-sil or plasma metal arc transfer in the bores, open top cylinder decks, non bearing equipped cam journals etc.) If you are building a total frankenstein mad science project you can still make a go of it, but its so not a daily driver type of project unless your both brilliant and desperate
If you go back to ChrisFix's head gasket seal video, he's got an older 3.0 Jag engine and after sealing the engine it got about 10,000 miles down the road before he tore it down and showed that a) the head gasket sealer "worked" and b) the block itself was warped, so changing the head gasket would not have actually fixed the problem, because the gasket was actually fine.
Take the bar and chain off or the saw and clean the hole" in the bar and on crankcase. The oil feed holes.
I am a strip it down and look into a rebuild guy..But on that engine with a guarantee you are probably making the right call.
im kinda shocked that your surrounding doesnt know how to check engine that blew headgasket. If block straight and head resurfaced, no cracks, itll be perfectly fine. Also you may go for better gaskets that will be more durable and wont suffer that much. Most likely those engines are prone to failure because of temperatures and heat overstressing.
Yep. It's not a guessing game of putting in a new gasket and see if it will hold. Measure all the tolerances and if there is damage to the head or the block you have to fix these, for example by laser welding.
Strange that they let go months later, must not check the heads? Might go soft after overheating, but you spend 5 mins and check that on a mitsubishi engine so why not a $10000 one
@@tortron I suspect more of these Cars suffer with cracked blocks rather than head gaskets I've head exactly the same issues with Fords and VWs
@@minimeee04 oh yeah, so they just do the heads and back on. A shame, testing blocks is pretty standard stuff, cheap compared to the labour of pulling the engine in and out
Man. You guys ought to open up a V6 Jag repair shop. Maybe buy his original engine and fix it.
Better do head studs and new head gaskets before installing the replacement engine while its out.Spunds like a clamping force issue and will definitely happen to the replacement so at least do arp head studs before installing
Hey man, great video. I have a 2017 Jaguar F-type s with a bad engine also. I found a similar engine off an XF model but not sure if the performance will be the same. I heard the engines are the and just the pcm tuning is different. Any thoughts?
Ha! I did that, but it was a 1976 Vega with an Aluminum block -- hot and then NOT. New engine, please.
Awesome video JR.
Hi I love your videos I have a question I'm doing an engine swap just like you did but the donor's engine its missing one sensor behind the a/c compressor and I've no idea what's for
Why not FCP euro for gaskets?? I'm having a nightmare trying to get a buick 3800 S/C running right. Wish I'd kept the jag with the ford 3.0D. Only problem I ever had with that was an alternator. I did a lot of work on the jag, but all as preventative (cambelt, trans mech overhaul, etc.). Didn't have to guess if it was metric or imperial, or drain the block through a buried knock sensor. Completely agree on buying new engine for the f-type. Alloy motor that's been cooked - that's a big gamble.
I thought you were being overly critical on this car when watching the first round of videos but the more indepth into this repair you get the more it seems warranted. I thought my SHO repairs were a bit much, PTO, Timing chain Waterpump, but they're a cake walk compared with the this monstrosity. Shame, I always wanted one of these cars.
Awesome video JR!!
Rocker arm cover gaskets. The valves are inside the engine and don't have covers.
That sensor is part number F666, it is the KTEG sensor...Kiss The Engine Goodby for the next time it blows up. They decided it happens so often it was worth letting you know. There is a corresponding light on the dash, a toilet bowl with circling water going down the drain.
Just saw a salvage jag close to me in Richmond, Va on FB marketplace. Too bad it is so far away, would have been a great parts car. Only wanted 9k, states the vehicle still starts and runs.
i love your channel but i know nothing about engines..so why am i hooked..lol.
I was at a Sonic yesterday, and I pulled up next to a Nissan Armada. The lady started it up. The thing sounded horrible, and water poured out the exhaust and died. It took her several tries to get it started and then she happily drove off spewing smoke and steam, so yeah some people drive until thoroughly dead.
It would be nice if parts for the Ford Duratec 3.0 V6 would interchange with the Jaguar engine, but I’m guessing that’s not the case.
jr that electrical connection is for the pulse width modulation controlled oil pump your going to have to swap that out
Ahhh yeah!! This is the video I was waiting for!! Awesome!
To me Jaguar's are some of the most attractive cars on the road, but you have convinced me that I never want to own one. I know you said that an LS swap would be too much work but it looks like it would have been worth it and you would have had a better car when you were finished. It seems that an LS Jaguar would be a lot more desirable and therefore more valuable.
Easy to convince you not to buy one if the only example is an abused and neglected model. The 4 Jags I've had have been no trouble at all.
Does anyone know if you can swap a 3.0 awd engine into a 3.0 rwd body? Is it the same block?
These Jags are sold all over europe and uk and have good reliability . Funny how only in the US do you have head gasket issues.
Well, that car has been properly abused during its life.
I believe FCP Euro carry spares for JLR cars, should give them a call it will be much cheaper than the dealer. That is if they have the parts as there is a delay on a lot of parts worldwide.
That new engine must have been dogged out or opened up for it to have valve cover gasket leaks at 34k miles. Hope you have a vin from donor car to verify mileage. They don’t leak that often at all.
send that engine to I Do Cars I'd love to watch him tear it down and see exactly how bad it is
Thanks I’m prepping for my swap definitely saved me some money I was gonna save it but I’ll get a used one
Fix vs replace has its moments. Had a disagreement with my manager over replacing an element engine vs having the cyl head repaired (broken valve, common when valve adjust is ignored) he wanted an engine put in. I wanted to repair. Luckily the customer chose my route, especially considering it was a solid 1200 less.
I've noticed that saw throws it's chain most when it's not level roll-wise.
Oh John Ross was hoping to see a rebuild on the old engine and what it takes to carry it out!!!!
The moral of this story isn't "don't buy a Jag" but "don't buy a cheap Jag that's been abused and you have no clue about its history". Treat 'em properly and they're no less reliable than any other make. I'm on my fourth and none of them has ever let me down. Petrol and tyres, that's all they need!
When I saw the first video of the car sitting in a junkyard, it was kind of a dead giveaway this thing wasn't worth resurrecting. I suspect it has more than 34,000 miles on it, or the previous owners were total boneheads.
2:39 -- I know this sort of situation. Though Its more to do with the people who run their gas tank down to the very last pipper between fill ups then cry about it when they are on the highway or in the middle of nowhere, run out of gas and are left stranded.
My dad never let his car drop below half a tank if he could help it. He always said that he keeps it topped up as often as he can just in case the worst happens and you need to go somewhere... And the worst did happen. Because There were multiple nationwide fuel shortages and while people were out there queuing 3hrs for fuel then fighting with people while at the pump. My dad was able to avoid this completely till the gas stations slowly managed to get their fuel supply back up. Then we queued 30mins for fuel and that was that.
Did I hear 40hrs on the head gaskets? When the engine is already out?
Maybe it's 5 hrs on the gaskets, 35 hrs on the engine removal and replacement?
@@OMGWTFLOLSMH probably that one bolt that snaps off and makes an hours job go all weekend
These cars are JUNKY POS'. We are sick and tired of JLR coolant and timing issues. We do a ton of this crap. We have built a parts list as a kit for when they come to our shop. The customer options are to fix all coolant pipes and hose or take it somewhere else. We are the only euro shop between Dallas, Houston and Shreveport that will work on them. Just shit...
from my experience the 4.2 and with new thermostat and coolant upgrade are pretty bulletproof right? do you have lots of problems with those on a wider scale
Good to get some real life perspective on these cars. I am too knee deep in German POS's to ever work on one of these. Though I did work on pre-Ford Jags and that was enough to say "never again". I figure any company that is too stingy to cast a separate V6/V8 block has probably cut some serious corners overall.
@@slasher9883 again, personal experience, but I have both a 99 xk8 and an 08 xk, both have been exceptionally reliable, I have put 11k miles in near a year on the xk8 in daily use and traffic, no issues apart from alternator dying at the end of its normal span, these ford period cars really are solid when preventively maintained. peak years are 1993-2009, I would not buy the later direct injection over complicated tata cars with timing chain issues
I’d be a little more concerned than you appear to be about that Milwaukee throwing it’s chain all the time. It’s not a very powerful saw, but still that’s not a bracelet you want to wear. Could be related to the lack of oil. A quick squirt with whatever fluid you have in a can would help if it’s just one or two quick cuts, chain is probably already stretched and trash though.
Maybe using a chainsaw like a toy is a bad idea, hmm...
My Harbor Freight cordless chainsaw still oils the chain after a year of use! 😄
Dip it in the old engine oil container each time before using?
@6:13 epic fail with the chain saw 😂😂😂😂😂😂😂😂😂
Just curious how much more it would have been for the V8? I know you said it would need a wiring harness swap, but hey if you're in for a penny, in for a pound.
This is John Ross we are talking about.....I'm surprised it didn't get an LS.... LoL
@@josephdougherty2399 The LS swap would probably have been cheaper 😅
That sensor is for the Doomahauger humdinger thingamajig
Underdrive Supercharger pulley probably contributed to engine blowing up. Seems like these are Ford engines already overstressed for more performance by Jaguar. I would leave stock pulley.
I for sure wouldn't use any parts from the old setup that failed. Put that new engine in and get rid of that car fast.
For the thousandth time, they're not Ford engines. Will you never learn?
Huh.. Pardon? "The underdrive supercharger pulley caused it" That doesn't even make sense buddy. Explain to me how exactly that would happen?
@@timk.537 extra boost can blow out headgaskets, then car overheats. Simple. Its spinning the supercharger faster to make more boost than stock. I have 2 supercharged cars for years. Also have a Jaguar XJL 2014 that I did timing chain and tensioner myself and everything inside the engine said ford on it. Probably why the hose routing is so crazy, making something fit several cars, like that water pump with the plastic outlet that always leaks, changed twice on my Jaguar myself. I still love the cars though. They just quirky.
@@racerx94 First, the supercharger pulley isn't an issue at all. This is a 1320 Eaton supercharger and your 2014 wasn't using the same model despite being the same engine on a differnt tune.. It's well known that this 126 engine can take considerably more boost, which is not achieved through the supercharger pulley, but by increasing the size of lower crank pulley. This model is rated at 380hp and 330ft lbs where many F-Type owners modify to run 450hp and 430ft lbs for years, with no issues at all. The designers at JLR claimed the engine can take up to 700 hp but producing those numbers would require a total overall. Still, these engines very rarely fail.
Again though, it's not a Ford nor has it ever been. This aj136 and the 5.0L Aj133 that this is derived from are not Ford designed. Feel free to read up on this from a reliable source outside this ill informed comment section. It's very well documented. Yes there are some Ford parts but this happens in every company that was once associated..every single one. That does not mean that Ford designed or manufactured the actual engine.
Another great video from JR. Thanks
You would probably need to get the block, pistons and head machined on both banks to be sure. No doubt you'd need to change all the shells, gaskets and timing chains which means you'd in for £10k at a minimum. Barum engines (on you tube) recently did something similar on the earlier model and it's an expensive repair.
The more I watch the excrement that you have to go through to keep these modern engines running, the more I appreciate the OM615 and OM636 that I worked on. Narragansett Bay.
Do as many gaskets as you can whilst it is out
Anyway, you can tear it apart anyways??? We’d love to see a break down just to see the fail point
I like how you're trying to keep it all original but this time a buick 3.8 would have been a better choice anyway i hope it works for you
Keep it Ford based with a 4.0 sohc lol
A 3800SC makes 100 less HP and weighs 200 pounds more, and good luck getting it to talk to that the BCM

Never re-build an engine, instead replace it. Good JR advice.
And why would you not replace the head gaskets on the replacement .? same mileage as old broken one. I can foresee a failure in 380 days.
Would love to see you tear down the old engine to find the damage.
There's probably a core charge on it.
@@skmetal7 take the head off to see the damage then slap it back on for the core.
@@skmetal7 He didn't get a rebuilt engine, he got one from a scrapyard.
Variable oil pump-type pressure sensor? My guess. 🤔
Would a 4.0L FORD V-6 fit within the space?
The 3.0's where ALWAYS a problematic...
The Jaguar 3.0s aren't problematic, they're cut down Jaguar designed V8s. No Ford input to the design apart from paying the wages of the Jaguar engineers at the time.
Another one.. The 3.0L aren't problematic. Where are you getting that from? Think about why they were used so much in so many different models over such a long time span. How would that make sense for any manufacturer, anywhere, to do that?
Drip a little oil on the saw’s chain each time before you use it.
It's the thingymajig sensor, which measure the dooveywhacker position and the whooseywhatsit temperature. Dam JR I can't believe you didn't know that? .......lol
Maybe that lower sensor is the electronic oil level sensor?
i would suggest the water pump y pipe as it’s the old design that likes to crack in two
Been looking at v6 f types. But you're scaring me. Maybe C6 Corvette with old faithful LS3.
I loved mine
I'm confused. If the engine overheats, it's a waste of time replacing HGs. Would that be a problem on your "new" engine too if you pre-emptively change them now, ie it would still fail in 4K mi? Seems like now would be the time to change the HGs - good engine and it's out. Then you should be good for another 30K mi. Putting this "new" engine in with 30K mi already on it sounds like a matter of when it fails, not if.
i was thinking the same thing....what is the point of putting in a different engine without changing the part that failed on this new engine...especially if both engines are the same in mileage?? this new engine is just a ticking time bomb.
Head gaskets are a “no problem, no pull” type of part. You can count on an immediate failure on 20-30% of new gaskets, even if you do everything right.
If you watched the earlier videos, JR said the engine failed due to some sort of coolant line failure, something like that will grenade any engine.
@@glassvial he also said in an earlier video, and again hinted at it in this video, that these engines are known for a high failure rate and that there is a company, i think he said in California, that tears the engine down and essentially makes it bullet proof with new/improved parts to prevent the common failure. so if JR isn't doing this, he's essentially just putting in a used engine that will fail sooner than later.
@@christophers.4007 they are soley damaged from coolant loss and overheating
no overheating = no warped deck no broken cylinder chunks
Solid choice, spending all that time and money to replace the head gasket. It is a gamble, and you seem to understand what your time is worth. Thanks for bringing us along. What is engine worth as a core?
Oil temp maybe?
Oil level temp sensor maybe
I was told if you want own a Jag, you have to buy two, because one is always in the shop...
That was true in the bad old days. You're clearly living in the past if you still believe that.
Thought I had spent too much on 2nd hand turbo for $400 and a whole Liberty GT for $3600
is the sensor for the oil level? If you are changing the engine why not fit the 3.0L diesel as a project? you'd get near 50mpg + in that body shell. Still around 300HP and a cool body shape...
I have the opposite problem with my Ryobi 18V saw.... The oiler works 100% of the time. It's just a gravity fed tank. 😂
Whatever. Still dang handy to just grip it and rip it when you need to knock of branch or two down.
Just scrolled through to see if anyone else posted the same comment. My Ryobi 40v saw has been excellent, so far. Hasn't thrown its chain once, and the oiler works every time... heh
@@michrech For what the stuff costs, you can't go wrong.
100% agree with replace rather then rebuild spent 3k on rebuilding a 89 honda civic and it failed the same way 6 months later
What was the failure?
@@tortron valve sticking open and burning the head because the aftermarket valve seals swell up causing them to stick. the man i got the car off of had the head redone before i got it because he overheated it
@@grandmackdady oh interesting, I guess you have to go oem parts
I did seriously consider the F type and I still think it is one of the best looking cars on the road today, but seriously why did Jaguar make this an almost impossible car to work on! Nonetheless, still looking forward to seeing it run again and hopefully with a careful owner it will give trouble free service for many years to come.
"trouble free service for many years to come" LMAO!!!!!!!
just because there is a head gasket leak doesn't mean the engine overheated and is trash....right? thought it ran ok in earlier video besides the gasket leak
So if you're replacing the engine, is there something that can be done to avoid a head gasket failure later down the track?
Same with all engines……pay attention to guages and warning lights, if in doubt stop Do Not press on.
Re-torquing the head bolts after 5k-10k miles, but on this car, that would be engine out, again...
Don’t MAP it would bee a good start in preventing future engine failure 🙈 IMHO of course 🤣
my mechanic is fond of saying, head gasket failure is typically sign of a poorly maintained cooling system. so, replace and flush your coolant regularly
@@andrethib id say its human head gasket failure…..usually to recognise the signs
Here's what I've learned from your channel and other similar channels. Stay away from "high end" cars. The only thing high end about them is the price tag for repairs and upkeep.
No, stay away from cars that have been abused and you can buy cheap. You'll end up payng the right price one way or another.
Can’t believe you wouldn’t start by power washing the engine off to get the old oil off. 👍👍🎉🎉🎉🎉🎉🤘🏻🤘🏻
I'd mess with the Supercharged straight 6 in the XJR , but I don't think I'd even mess with this one, as adventurous as I am.. There's an engine rebuilders channel from the UK called Barum Engines, and he doesn't even want to mess with these engines, he tells potential clients to price a new engine as the amount of hours that would go into a rebuild would get close to what the OEM would charge for a replacement engine. And as luck would have it most of the time, you do the work and then the car comes back in a few thousand miles with a failure or noise in the engine, its just not worth it with these over-engineered engines (try that for a mouthfull!)
My 2014 F Type S failed as well :( ... what kind of price would I expect to pay on just the labor to take the old one out and put new one in? Not including the price of the engine. I will source a used one. Thanks
