I like how this guy is super clean while doing a major job. It makes it look easy
Guys wearing a watch haha classy mechanic
and sports new hair styles between scene!!
Using the Atlantic British video & Head Gasket Kit allowed me to replace my bad gaskets. Great video & thorough; there was not one component left out.
You guys are amazing. Seriously. Thanks so much for these videos, they are the number one reason my Land Rover Discovery 2 runs as smoothly as it does-I've had your great, detailed videos helping me through dozens of maintenance and repairs. - Matt
I have never seen such a detailed repair video. Thank you.
you guys are legit my saving grace. my serpentine belt broke and without realizing it ruined the gaskets. its got 200k miles and has been sitting a while, got the serpentine belt back on only to realize the gaskets are super loose because radiator fluid just POURS into the engine, I can smell it - see water in the oil cap all signs point to very very bad head gasket. oddly enough water pump is fine lol. THANK YOU GUYS! going to tackle this next weekend
Doug I would do anything for you. Literally anything. Started this tutorial cause I'm broke and by the end I achieved some sort of new level of enlightenment....enginlightenment maybe....
By far the best overhaul walkthrough I’ve ever seen. Well done my friend 🍻
I just wanted to say a big thank you to Atlantic British for doing these vidoes. If I lived in the U.S I would certainly order all of my parts from you in appreciation. Super helpful.
I just wanted to thank you for this video, everything went well and the instructions show how to remove stuff in bulk which really helps.
Our Disco II blew a head gasket 820 miles short of 200,000 miles.
I would remove the throttle cables first and then remove the AC unit... works great. We had the heads resurfaced, installed new lifters (they were on sale), installed a new water pump gasket, new thermostat, upper coolant hose (because the bleeder broke) and replaced the coil pacs because its a PITA to replace these.
Also just remove the exhaust manifolds if you don't have a lift, I ended up doing both because its easier to put it all together with the manifolds off completely. An air ratchet really helps putting the manifolds back on in this case.
Doing this now on my 99 disco2 V8 Bosch engine thx for the introduction sir! Keep up the good videos
Thanks for the video. I used your video to fix my Disco II and I am not a mechanic, but I fixed it where it is not leaking oil and water thank you. I also got the quality parts from you guys, which are working as expected so far. The car has 17K. Again thanks
How this goes with the secondary air system in place on a 4.6:
* One of my "Y" pipes was seized on the fitting on the head, and I didn't realize (because you cannot see) that you can grab the fitting to keep it from spinning if that happens. In my case the pipe was damaged before I figured that out, and I had to get a good used "Y". The nuts on the "Y" pipe are 27mm (or 1-1/16" if you have more SAE tools than metric). The fitting into the head is 19mm (or 3/4"). The fitting only has four flats, not six like something normal.
* It's difficult to get to the lower head bolts below the aforementioned fittings, things go a lot better if you take the fittings out of the heads before trying. To do this, take off the upper exhaust manifold bolts which sit right next to the fitting, or else you won't be able to swing the wrench well enough on the fitting, especially given it only has four flats.
Once that loveliness is out of the way, you're down to what you see in the vid. I tackled the secondary stuff just after pulling the rockers and pushrods.
As a bonus, on the back of the right-hand head is one of those "christmas tree" wire ties holding some vent pipes (?) for something or another. If you're wondering why your right head won't come out. Also beware the head will probably still have water in it, which will come out the back, right into cylinder 7 or 8.
What a super helpful video for you guys to put out there. !! Thank you
Tip !. replace ignition coils and spark plug leads at the same time !.The expense is minor !, If you are doing the head gasket and it will take minuets instead of hours !.
@33:00 I remember in high school (1987) my auto mechanics teacher came over to inspect our 3-man group's V8 engine that took us 4 class periods to wire up the non labled HT leads from the distributor to the spark plugs . He took one look at it, said 'great job', and then yanked all the HT leads off of the engine and told us to do it again. We were so pissed! It took us 20 minutes to recomplete it and understood why he wanted us to learn from it.
At 50 years old I can still do this with my eyes closed.
Kudos to any man who wears his nice leather band and Polo shirt to do this job.
Excellent guide - something I need to do real soon as insurance policy - 356,000 kms without any issue, but taking half the top end off to do leaky rocker gaskets, I may as well go that little bit more and do it properly! I would recommend replacing the plug leads and water pump while you're there, regardless of how they look.
356,000 without any issues! I envy you. I'm just under 200,000 and starting to have some persistent coolant issues, burning oil smells and various minor issues with central locking, electric windows, etc.
Thank you so much for this video and whatnot
hi sir
I am very thankful of your clip
This is a huge help ! Thanks :-) Using it for my 2001 4.6 HSE Range Rover... which seems
to be identical..
Very helpful and straight forward video... nice job man much appreciated .. keep up the good work
My top manifold did not slide forward as far as yours. The monkeys that did this last time stripped the screws mounting the coils. I’m resourceful and optimistic but I hit snags like this constantly it seems.
Awesome video, I’ll be doing this to my D2 here shortly so this came in really handy. As always you guys have great products to keep these beasts running.
Nice video , thank you Sir , hugs from Croatia.
Huuuuge thanks Doug, I'm doing the heads on this exact engine and by following this vid it's made it so much easier. Genius.
Great information
Amazing. You may have given me the balls to do this and save $2500-$3000.
Thank you very much I do appreciate your time.Thank
Fantastic video
The trick with the AC lines to get the coil out was perfect. The pain I endured to plug those wires in after inserting the coil is still with me.
Michael Pettit you have to pull the coil wires before the manifold will come out?
Great video.
Thanks for the vid!
You mentioned how to check for a leak or slipped cylinder, did you skip it or did I miss it? Thanks
Hi... I continue to strip the head because the rings from piston were burn but instead of reassembling back the same engine we use another engine from a series 1 Land Rover( both engine were the same size 4.0). We use the same harness from inside the series 2 but had to change the flywheel. With all said and done the engine swings but doesn't start is their a specific way the flywheel is suppose to set with its original camshaft sensor.
sorry, not sure if you are swapping in a different engine.
Hey guys, I just did my headgaskets and timing chain on my 04 D2 and have a ton of CELs. Truck runs great, stays cool, and doesnt leak anything. The following is my laundry list of codes. Im thinking bad ground somewhere?

Sounds like you will need to take it somewhere to be diagnosed or get a diagnostic tool that will be able to pinpoint the source failures for the codes.
Might be something as simple as checking grounds. If they’re fine, yeah gonna have to take it to a garage that can run better diagnostics.
I am embarrassed to say that upon second look it was that #2 fuse! Truck runs great! @Atlantic British, thanks for the incredible video.
Obababoy good to hear! I’m looking at a cracked head on a D1 3.9. Gonna be tearing it down this week.
Is he using non-impact sockets with an impact wrench? Just asking for a friend.
Can the secondary air system be eliminated on an '04?
Any videos on battery drainage for 2003 disco 2? Have this constant issue, burned through two batteries, issue with positive battery terminal, just bought repair kit for it, about to throw on 3rd battery with new terminals but not sure how to find parasitic drain if any. Had this truck since new almost 19 years. Had the worst 6 months with it. Have to boost it every day to.drive it. Please help
Same vehicle, same engine. I can hear coolant moving thru my heater core when I rev the engine a little. It doesn't miss though. Head gasket?
22 thumbs down people can take a long walk off a short pier.
What is secondary air? Lol it's funny because the hard part is just getting to the engine lol
What tools do I need?
2001 land rover discovery cruise control cable do you have this part .
I'm a bit late on the uptake, but could you give me some advice pls? I'm thinking of buying a 2000,Disco 2 V8. I'm confident in mechanics to perform this fix, but is it always a cert that the head gasket will fail? Also if you strip it that far is it best to get the bore liners changed or is it rare for the liners to fail?
liner drop is a common problem on old Rover engines. Retrofitting them new "top hat" style liners that prevent future liner drop
is certainly doable, but you will want to go with a shop that has done that before and knows those engines and their common issues (like oil sump intake grime and grit and making sure that vaccuum system is clean to prevent engine overheats - one example)
is it easier to use the Arp stud kit rather then the head bolts the kit comes with and why ?
If you use the studs, don't put the studs in the block until after you mount the heads. So, replace gasket, mount heads, insert studs, tighten using allen key. There's no way to mount with studs if the engine isn't out of the vehicle. Make sure you clean out the threads with a chaser, brake cleaner, and compressed air before you begin. You'll need to test that you can finger tighten the studs and they won't meet resistance.
You think I can clean my upper intake, lower intake manifold with kerosene?
27:34 TS DOES NOT PULL RIGHT OUT😔 penetrating oil and 3 guys pullin on that thang and nothin😔😔
Dear sirs,I have a Landrover Disoverery 2 2001.I need to replace my head gaskets in mine.I watched both videos by Atlantic British,The first video is about 53 minutes removing the upper and the second video is about a hour and a half.In reality how long does it take because I can do it but I know it can’t all be done in say 2 hours.Does anyone know?Has anyone done this and knows how long it would take?Mine over heated because of a bad water pump and I have had a few opinions some say I might have to get reconditioned heads because my heads could possibly be warped?Any body have any opinions Thank you.
Tough to say if the heads or warped without them being taken off first and having a technician inspect them.
That said, if you're doing your own head gasket replacement, make sure you get new head bolts as well. The OE head bolts are one-time use stretch bolts and should not be reused and torqued again. We do sell head gasket sets that include new headbolts: www.roverparts.com/Parts/STC4082BKA
One other thing to note, a common problem with overheating on these older Rover engines is the Oil Pump Relief Valve. You should checkout this video about our remanufactured engines at about 4:05 for discussion of that issue. th-cam.com/video/nA8IXZR5rPs/w-d-xo.html You'll want to make sure that valve is clean. If it's not, it could be the primary reason your engine may be overheating. Sleeve drop is also covered in that video - another common problem in those engines.
It was 6 hours in and 6 hours out...
Dr. Guy Madison did you do this on a D1 or D2?
@@spikedog23 D2, a D1 would be similar... it's a rough guess, I split the time up across a few days as I had the time and a plan in mind of how much work I would do each day.
Just remove the exhaust manifolds and save yourself some time, I removed the entire cat because I wanted to inspect it as I had a clogged cat in the past.
A DeWalt 3/8" rechargeable impact wrench comes in handy... it really speeds things up.
Dr. Guy Madison thank you for your response. I was just in the process of doing the valve cover gaskets. I decided to take the rocker assym off for sludge removal and cleaning. While cleaning the oiling holes I dropped the drill bit I was using in the oiling port. So now I think I may need to take off the head. Do you have any suggestions?
my land rover because it is slow on road climbs but in dirt road is fast
I'm about to do this repair myself on a D1. Is it necessary to depressurize the fuel system first?
It is necessary or else you will have a very big mess all over you and your engine.
Hi my name is Jesus I have a 2002 Land Rover discovery 2 with secondary air and I have like 180 000 miles in I will like to know if You recommend me to do the heat gasket repair or rebuild all the engine the truck it was over heather more the one time please let me know what did you think
At 27:10 there is a heater core pipe that goes into the lower intake. What is that called? Does anyone have a part number? I completely ruined mine.
Excellent how to video. Big job and it highlights some terrible design features such as that ignition coil totally buried at the rear of the engine. I saw one of these for sale yesterday for $3200 Australian. Comes with a spare engine. Having watched this I am not sure its worth all the effort. His own mechanic turned down the job which speaks volumes to me.
Fuck the fan. Couldn’t get it off to save my life. Just worked around it
Is this video applicable to a Disco 1?
yes, only difference is less electrical stuff in d1 and no tricky to get to sensor on the back of the drivers left head
What parts would have hot tanked?
None. Anything that is aluminum will disenagrate.
You guys think, I can do this by myself, I never done nothing about mechanic or something like that, you think that’s is a good idea?
In all honesty, probably not. If you are not mechanically- inclined or have zero experience working on cars in a DIY setting, this probably not a job to start with. Hire a good mechanic.
Iloveu
Oh my goodness my truck has bee sitting for 6 months.
I gotta try this myself. I've already put way way too much I. It for my kids.
I'm broke now but I'm gonna a try it.
Oh if anyone wants too come help it's our o lyrics 2006 range rover.
THINGS SUX W O E LEG.LOL
Plot twist...block was scrapped due to slipped sleeves
Oven cleaner from the dollar stores, is great to degrease the heads.
I give the one finger salute to every Disco II i see. Worst POS vehicles ever made.
