Your video brings back memories of my rebuilds on my 1965 & 1966 S types motors and restoration process.
Dad gave me a 1947, 3-5 litre Drophead Coupe in the 1960s . Still in the family. Did all my own servicing with dads help. I can recall taking the starter motor off and setting on the bench. “What are you doing with that ?“ asks dad. “ Taking it down to get fixed” I reply. “ No you’re not. You’ll repair it yourself. “ says dad . So I stripped the armature re-lacquered a hundred miles of copper wire, rewound and baked the armature in the kitchen oven.
Recovered the fields etc. put it back together tested it. “Yay presto works!” “See how much money you saved” says dad. “Yeah. Thanks dad...”:50 years later still remember it. I’m now in Aussie and the car’s in NZ Still drives ok. Richard, just found your great video. You got yourself a new follower.
What a wonderful way to learn about XK engines.
Yep we certainly want to see this job completed with more video's. Thanks

You’ve warmed us up, now we need to go the full trip, all the sights, all the stops and starts......please My Father worked at the Jaguar factories in Coventry for 36 years, he probably made the chassis on that Jag. 🇬🇧👍🏻
What years, please?

I saw my first XK120 in my village of Houghton Regis, Bedfordshire, price £55 , i was a ten year old and pesterred my dad to buy it, wisely he didnt, but i got the bug, i am enjoying watching this video so much so a big thank you, from Cheshire UK
as a former owner of a MK7 and 3.8,( dad had a XK140 Drop and a E) i found this a fascinating journey into the distant past.. Keep it coming. thanks
We have a 1952 XK120 Jag that we inherited from my father-in-law when he passed away last year at age 92, it has been restored to its original trim and, thankfully, has a fresh engine in it.
This video has been incredibly useful to me, keep them coming on these Jag DOHC inline 6 engines! I've got ours running like a watch now and want to keep it that way.
I never gave a twit about the inside of a Jag engine, yet I found this fascinating & watched every second! Can't wait for the rest. It's so much more interesting than just another standard V8 build.
Great instructional video - I'm taking notes in prep for rebuilding my xk120 motor this summer !!!
I admit I have not seen any of your videos in a while, glad to see your dad is still staying busy. Thanks for sharing about this early engine. Charles
I've developed a fascination for vintage car engines quite late in life and I find your videos easy to follow and very enjoyable. I look forward to hearing that fine old Jaguar engine purr once again.
For an old guy like me it is hugely entertaining to see this job done so well ! Wish I had the facilities and tools to do it myself still, but your video is a tremendous replacement and very educational..... keep doing these great jobs. Probably a useful suggestion is to maintain a website with additional notes on details, plan, parts etc. for those who like the same challenge in future!
I love how every step is explained in a very pleasent way. Great editing too. It feels more like watching a part of an art restauration process than a mechanical job. And doing this together with your dad is just awesome.
Great work, I’m from Coventry where this was made and have grown up with Jaguars. I liked the care taken with this strip down and very impressed with the 1950’s engineering.
The careful and methodical disassembly technique added to the clear descriptions of rare early engineering technologies comes only after years of study and experience. It is difficult to imagine the heart of this old girl being in better hands. And thanks to dad too. He must be very proud.
Thanks Larry great to hear from you.
Wow such a teaser, yes, please finish the rebuild of the engine as well as the fixed head coupe😊👍
Hi this brings up many happy memories. I was born in Wellington New Zealand and my mate Mathew Gibbons, he had a dad who was a mechanic, who repaired Jags only. His dad had an XK120 - I think - but it was a hardtop. (I thought it may have been an XK140 and it was before the E-Type).
I remember travelling to Levin north of Wellington going to a race meeting. We were cruising nicely and I was spread out in the back seat so I looked over at the speedo and we were doing 100 mph. Seemed effortless. On a nice highway out of town of course
I remember he made most of his money repairing the LSD diffs on jags and doing routine services and some engine rebuilds. Lovely to know these cars are still being rebuilt.
Those long camshafts, with so few lobes, always surprise me when the cover comes off, compared to modern engines.
I really enjoy these videos, with his vast experience and enthusiasm for whatever he’s working on.
If you type " 1961 jaguar factory tour " you will see these engines and jaguar cars being made.
Great to see these guys saving one 👍
Yes Glen the 1961 Factory Tour video is a real gift. Too bad it doesn't cover more E-Type production.
The shifting spanner you used for the distributor drive looked positively ancient, I have some which belonged to a Grandfather who was a steam engineer!
"Otter switch"...Otter Controls, Buxton, Derbyshire...I was US rep for them in the 1990s...went to the factory several times. Spent a lot of time in Detroit with their sales and tech guys, calling on middle tier suppliers, and Ford, where we were warmly welcomed because one of the main SVT guys was a Brit! Moved a lot of Otter switches, mostly for window lift stall protection, but also some applications in coolant sensors, like the one shown here. I have an MGB that has one of the venerable disc switches mounted on the top of the radiator. It tickles me to see them! Otter was also really keen on tire temp and pressure sensing technology for a while, but the only application they found was in a few F1 race cars. Their system was over-specified for the mass market, however, so we never got them into US manufactured vehicles (but we had a time every spring in Detroit, displaying at the SAE for a week at Cobo).
Boy this video brings back memories. In 1960, I bought my first car. A 1954 Jaguar XK120M, for $800. Ran great . Then one day something happened and the engine had to be removed to fix the problem. A friend who owned a shop did the work to fix the car. My task was to take the head apart and do the valve job part of the repair. This was the first time in my life I ever worked on a car. Slowly one by one I replaced all new valves, springs, spacers, and bearings. Tightened the cam shaft down checked the clearance, and repeated it if the clearance was off. Put the car back together and attempted to start it. Would not start, then discovered we had put the wires into the distributor 180 degree out. Switched the wire and it started right up. One thing we did was shaved some off the head. That had a big impact. At 2500RPM, it was like the car was kicked in the butt, and it took off. What surprised me years later was the 120 had a metal timing belt in 1954. At the present time my 2001 Ferrari 360 has a rubber one and it was not until the Ferrari 430 came out with a metal timing belt.
My dad did an overhaul on a 66 E Type V-12. Had to use the engines compression to blow them off. That was a neat learning experience for me!
Thanks for the detailed process of this engine rebuild Richard - takes me back to my youth, when I worked on these engines back in the 1960s... as soon as I see the camshaft covers I'm back there 😊
Having been raised working on big block Corvettes and restoring them for almost 40 years, and now working on LS and LT engines, it's cool to see something different. Very well done video. Entertaining and informative. Look forward to seeing the rest of the build.
Yes keep showing more of it and the car to
Looking forward to the continuation. Thanks
Yes, please more of these great narrated videos! Love it to learn more about Jaguar history. Big thumbs up!
This engine brought back some memories. I had a friend in New Rochelle High School in the mid seventies
who was rebuilding an old Jaguar like this one. I remember what surprised me was the cylinders
were the size of paint cans.
Vapor blasting is the way to go, glass bead with water, everything stays nice and cool, no dust or grit, beautiful finish.
One of the most beautiful mass produced engines built.
We want more videos !! Please. The XK for sure and the 1952 engine as well. We can’t wait for so long the best Jaguar videos on RUclips... yours 🤗
Sure do want the rest of the story. I rebuilt a Jag 6 in about 1966. Not this engine, similar but more sophisticated, probably a XK140 or 150. I remember being delighted with the design, and the rebuild turned out well. We had many fewer issues since the engine we worked on was in good shape and running, but off it's feed, needed valve work mostly. We replaced rod and main bearings, rings but not the pistons which were in good shape. As I recall the cam bearings were fine, we may have replaced them but I don't remember.
There is one thing I hope you can shed light on. This was my first Jaguar engine rebuild. We had the shop manual, and carefully followed the specs, but when we came to finishing the valve work, the manual said "do not lap the valves". We looked at each other and "What??" We always lapped valves carefully, considered it a final touch of precision and pride. We talked about the issue every which way, and finally lapped the valves. We simply could not imagine why that was in the manual. The engine worked great, we double checked the clearances, and there was no problem. The customer was happy. The engine was happy, we were happy.
Any light to shed?
Hi James yes I prefer to lap valves to verify the fit. Fresh from the machine shop with a triple-angle cut, it probably doesn't need it.
@@RichardMichaelOwen Well, we were the machine shop, did the 3 angle work, and still always lapped. Don't like "probably" when I'm working on machinery. Although once in a while you can't get away from it. I wound up answering a frantic "help!!" message from a friend of a friend up in the mountains in Big Sur. Found him, his girlfriend, and an urgent need to move - with an old Plymouth six - about a '49, with a knocking rod. NO parts for miles, no money. Took off the pan and found a spun insert and lots of nasty on the crank journal. Had emery paper and a mike. Spent quite a while getting the crank round and smooth again, and asked the guy if he had a really strong leather belt. Yup, I had heard the story sometime, so I cut a bearing out of his belt, cinched it down with the rod cap, got the pan back on with a lucky tube of sealant and the old gasket, and took a deep breath. Fired it up, and it ran just fine. I told him to keep the revs down and go as easy as he could. Last I heard he made it back to civilization, and was very grateful. I heard it worked a lot longer than any of us thought it would. (When I heard the story about the leather rod bearing, I can remember being super dubious - but there I was, with nowhere else to go. And it worked. Phew.)
So any idea why the Jag shop manual had that "don't lap" note in it?? If you have an old shop manual I bet you can find the note in the valve section.
Definitely want to see the rest of the motor build. Am following this build, can't wait to see the finished vehicle.
What a beautiful engine. Looking forward to seeing this one finished.
So much knowlage needed to do this work. Awesome to see stuff like this being rebuilt for a new life.
Nice!! Im 19, just finished up a 4.3 rebuild thats goin back into a S2 E-type, had no clue people would be so interested in this stuff! Makes me want to video the next engine overhaul, thank you for passing on the knowledge for those earlier XK engines! Cant wait to use this as a resource.
Cheers!
Thanks Richard ⚓️ Hi… I use scrap area rugs carpets under a block… carpet shops give them away ⚓️ also scrap leather…. Scissors up an old pair of boots… use the leather to cushion pliers/hammers… avoids tool marks 😮
Certainly do want to see it taken through to completion. Really interesting, thanks.
Another really interesting video, thanks, and definitely would like to see more as the rebuild proceeds.
Excellent, thorough work. Ihave rebuilt many of these engines. I wish others worked as carefully as you do.
Welcome back Richard, hope you and the family are keeping safe and well. Really loved this step by step on the old 3.5 XK engine, I had one complete with Moss gearbox sitting under my house for 25 years, guy that I bought a nice manual 1966 3.4S Type off threw it in with the deal, it even had a complete pair the early type "long neck" 1.75 inch SU carbs on it. I had to dump the whole thing when moving interstate. Yes, more please on all your jobs.
Richard, as an old aircraft crash investigator I can say that there is no doubt that gravity can warp aluminum.
Love it. Old school stuff. Remember it well. Got to show us the rebuild and finished project. Good work.
Great video thx, looking forward to see what's up next 👍😊
I like how you opened this engine so carefully yet knowingly, you clearly know what you are doing and that fascinates me, thank you! It seems like you're caressing the engine! :)
Brilliant job. So nice to see a professional restoration! Thank you.
Excellent, so very interesting, please show as much as you can, it is all very much appreciated.
I'm an Italian car guy. But, I love the jag engine! A really good dismantle and diagnosis. This guy is good. Thank you so much for a great video!
I most certainly want to watch Chapter two of the engine rebuild!!!!
Came across this video unintentionally. Made me wish I had such a source of information some 50 years ago. Had an XK150 which dropped a big end not long after I purchased (second hand with a lot of Australian miles on). Started the rebuild then married. Never finished it, but did keep in touch with the purchaser for some years. Rebuilt to Concourse Condition over the following 15 years.
Yes, definitely show more work on this project!
Very interesting, thank you and it would be great to see the next steps in the rebuild of this engine. Kind regards, Richard.
Great to see you back! (as this engine was made in England, it's made from Aluminium, not Aluminum LOL!!)
I love it. Looks so much like the first engine I ever rebuilt which was the 3.8L out of my '63 sedan circa 1972. Thanks for the memories. I finally smarted up and am currently rebuilding my '90 Toyota pickup which I bought new in 1990. Brits vs Japanese. Huge difference in engineering.
I was apprenticed at a Jaguar dealership in the 60's. Never had to fully strip one of these.
Yep! Wanna see more! It's been 40 years since I rebuilt a Jag... a couple of sixes and one V12 back in the day. The sixes were good memories that this brings back. The V12 was the stuff of PTSD. Imagine a '70s V12 overheated to seizure.
My brother rebuilt my 53 XK120 Drophead Coupe back in 1968 so yes I’m interested to watch you finish this project 😀
Definitely want to see all of the things you mentioned. From parts to machining.
Great job 🇬🇧
It is great to see such an iconic car being brought back to life. Using as many of the original parts as possible just adds to the authenticity. I have just found your channel and it is really great. I am from the UK so it is very nostalgic to see something from "home" being worked on so lovingly. Thanks very much.
The red stuff (paint) on your bell housing bolts stops them from reacting with the aluminium casing, steel + aluminium + water = galvanic corrosion.
Looks like "red oxide" (metal primer) paint.
@@_zzpza Red lead
Its red lead usually so don't breath in the dust,
I would say that is old school "Red Oxide " primer paint.
On boats you hang a lump of magnesium off the rail attached to the ground system to help prevent galvanic corrosion. They sell cast fish anodes for that purpose in marine shops. It can be a real surprise how fast those anodes disappear in some circumstances,
Definitely looking forward to seeing more
Great video! Definitely want to see more.
Bucket lifters. Impressive for 1952.
Very interesting. Looking forward to seeing how things progress.
i could settle down and watch these two special guys 24/7 with their restorations, its a science
Yes, let's see the rest of the project. Thanks Richard!
Good to see you back Richard, love to see the rest of the engine build, and good to see a box of Yorkshire tea in the background 👍
Yes please, would love to see this engine rebuilt 👍
Nice detailed video, yes please do follow up on this engine build. Nice to see it get assembled and fired up! The red paint on the bolts is Red Lead paint for an anti corrosion. Usually used on ferrous marine applications.
@MichaelKingsfordGray yes it it just don’t lick it! It’s perfectly safe to use!
Absolutely want to see more 🙂 Don't leave us in a vacuum now !!
Hi Richard, my body was built in 1952, so this engine is as old as I am, and probably in better shape! 😊 love these videos, compelling, can’t wait to see the next instalment. All the way from New Zealand.
Yes! I'm diggin' this project. Love to see it through.
OK I had finished commenting, YES we all want to see the XK engine re-build, and stop screwing around and give us video's on the XK150 whats the matter with you :)
Yes hopefully one at the end of this week.
Fascinating. Keen to see the next episode, and to see more of the XK150 rebuild.
Richard - Definitely want to see the full rebuild of this engine. Will really be interested to see if your machine shop can save the head. Could not believe how easy the engine came apart, especially with all the internal rust.
I was having the same thought, amazing how easily a 70 year old engine from a neglected car came apart. Probably a combination of luck and a mechanic who really knows what he's doing... A joy to watch.
Please continue, fun to watch the disassembly.
I no longer change even a radiator cap, but, geez, I enjoyed this video.
Thank you so much guys......loving it, nice to see ya'll again
I had my damper re-rubberized if you like I will find out where I got it done, as I know you like to keep as much original as you can.
Yeah that's a great idea. Later found out these are readily available brand new. Looks like they didn't change the design until the 4.2 came out!
@@RichardMichaelOwen Mine was done at .
Damper Doctor
1055 Parkview Ave.
Redding, CA 96001

Cost me $289 incl. shipping but that was a few years ago (2016)
Keep up the good work. More video is always welcomed.
Thanks RMO, tear downs are always fun to watch.
So far so good! Keep going on the XK 120.
JIM
Yes please bring us along on this journey. cheers.
Absolutely want to see the motor rebuild! Fascinating project, and great info.👍
Thank you for getting back to me. Must say your channel is very professional and enjoyable to watch. Look forward to future videos.
I love these detailed tear downs. Keep up the great content. Keep Safe Richard, love from England
Interesting. thanks for taking the time to make this video.
Good to see you back on the screen Richard. I've just rebuilt my 1950 120 engine - studless cam covers, bow front engine mount etc. - so it'll be interesting to see how you tackle this. Looking forward to more on the 150.
Tim, great to have you along, so your engine probably has even earlier details like the smaller water pump, the earlier block, 6-bolt flywheel?
@@RichardMichaelOwen Indeed, plus tall dashpot carbs and the deeper cast aluminium sump. Good luck with the oil level float mechanism. I could never get mine to stop leaking. I've had some aluminium blanks made up to go over the hole. If you find yourself in a similar position and want one just let me know.
Awesome Richard! Thanks for sharing :)
Great vid, and so sympathetic to a piece of history
That was great (as usual!) Richard, thx very much 👍. Really appreciate the effort you put into producing these; very interesting. Look forward to watching more showing the process through to completion. Thx again!
Old Jaguars are great looking cars:) if only I had all the monies, lots of old cars in my museum garage and a small apartment/studio sized living area inside to overlook all the cars lol
When I was 15 in 1962/3 here in England, during the big freeze winter, it was nothing to see cars with bonnets(hoods) up, with core plugs on the blocks, sticking out on a frozen column several inches long! This sometimes saved the block from cracking! Antifreeze was apparently an unknown quantity to most DIY motorists running their cars on a shoestring,! So those quite thick core plugs did a very useful secondary job after the manufacturing stage too! I had two Mk 2’s and shudder to think What they’d be worth today? Had to sale the two for less than £100 as fuel rationing was coming in! Arse!
Definitely want more on this one 👍
These videos are so well done as is the careful methodical work on these beautiful works of auto art. Please keep it going Mr. Owen. Thank you so much for your hard work and sharing!!
I can't wait to see this motor restored, tuned and running!! I want to see you guys driving this car already!! Can't wait!! Looking forward to the notification of the next video being posted!!
Now that we're on the roller coaster, we can't get off until the ride stops.
Fascinating - many thanks.
