- Finally getting into stripping down the 948cc OHV A-series engine from the Morris Minor. Needs a good overhaul but nothing too scary looking so far. Here's a more detailed strip down of the cylinder head.
The car is a 1958 Morris Minor 1000 with the 948cc engine. Last WOF was in 1995 and has been parked up ever since.
Here's the valve spring compressor I used:

Never seen a more usless spring compresser in all my 71 years !! Best place for that thing is in the bin !!
It's definitely a contender for worst tool ever. Cheers
"Lifetime guarantee" is something most of us were familiar with back in the day. This is the legend that would be advertised on the packaging box or leaflet that came with the tool. And some manufacturers even thanked the buyer "for purchasing their tool". Lifetime was taken as 50 years - a generic figure - and the tools would last the distance as long as the manufacturers "How to use and service" guidelines were followed.
The Toledo valve spring compressor fell out on the third spring, how times have changed!
I don't mind the rain noise one bit...something rather cozy about a bloke snug in his shop with the rain outside...something rather wind-in-the-willows-ish about it.
I didn't realise how loud it would be on the video. I couldn't more the lawn so thought I'd tinker in the shed. Cheers!
You're not wrong actually:-) There is something about that.
Hardly ever hear rain noise downunder.
@@graemewilliams1308 growing up under corrugated iron roofing I definately heard the rain
that vavle spring compresor wants launching into the nearest bin
You're not wrong
Ha ha
Heart shape combustion chamber ........HIGH PERFORMANCE ! ...... Love your videos great stuff....Keep up the good work.
Cheers mate. I'm dreaming of 50bhp with this build 🤣
You’re off to a good start! Although that spring compressor looked a little aggravating to use, it got the job done as you said. Great work! 😀👍
Aggravating is an understatement 🤣 I'll definitely need a better one for the reassembly. Thanks Terry
Love watching engine tear downs, these old engines seem very approachable! I noticed that your burn't exhaust valve sat adjacent to the one completely blocked coolant passage, coincidence?
Great channel, came across it by chance and am now subscribed. I've lost count of the times I have had to crawl around on the garage floor looking for a collet that decided to make a break for freedom so glad to see you managed to save all yours despite having the worst spring compressor I have ever seen :D Keep up the good work on the Moggie.
did my apprentiship on these..2 yrs making rcond heads:)...good tip remove the circlips the hit every vavle coller hard with a hammer...breaks the seal and makes it much easier to compress the springs
Fascinating stuff tearing down the moggy engine great work going to look and run fantastic when it's done ✔ 👍
finally I have caught up to present day . good stuff
Awesome. Thanks for watching
I made my own valve compressor simply by bending double a length of 5mm steel rod. It hooks under a nut & washer on a rocker-assembly stud. Press it down on the collet retainer to free them off. It takes seconds.
That sounds better than my junk one
Make sure you replace the head studs and that way you wont end up ripping your knuckles like I did when one broke when I was replacing the head and tightening it down.
The Morris Minor I did a valve grind on in 1968 at age 16 had large holes burned into the exhaust valves.The head and valves you have there looked pretty good.I had to improvise with compressing the valves.I wish cars that simple could still be had around here!!
Apart from that one valve they seem pretty decent. This project seems to be bringing memories back for lots of people 😀
fair play for having a go, always a good idea to get a socket and tap on the valve spring caps before trying to free the collets off as it can free them a touch from being wedged hard into their little tapered seats, good luck with the rebuild
I did find tapping them with a hammer did help, the socket idea sounds like a good plan. Cheers
my first car was a small window low light from 1955! i think i took the motor out of that thing 10 times! a mixture of no money and no knowledge seemed to be the problem!
It's a great car to learn on 😀
I haven't rebuilt an A series since i left NZ in 1980. Today I wouldn't bother with the original head but fit a metro head for the better ports, Stellite valve seats, sodium exhaust valves and NO Cracks. I think there is a couple of studs in different places but otherwise it's a close fit. Don't forget to fit a New oil pump. The old ones have tendency to fail when faced with having to pump oil against new bearing clearances. My Dads older sister had a few Morrys in Hamilton. One,a nice black one was stolen around 1970. In 1979 the cops knocked on her door asking if she wanted her car back!!!. it had been recovered and was pretty dirty with rust but otherwise OK after being parked somewhere for all that time.
Great job mate, I was watching and thinking it’s going to look so nice all cleaned up new valves new green paint , keep at it cheers 👍
Cheers mate, I think it should turn out great 😎
Heart shaped combustion chamber, how cute lol. I enjoy installing valves. It's satisfying how nicely they fit.👍
It is very therapeutic. I'm looking forward to the reassembly
Oh yeah scrape that head surface😂 love your videos mate keep it up!!
Haha thanks
Nice work, go ahead.
Didn't show getting the thermostat housing off, glad it was an easy job for you. Mine had welded itself to the studs and I had to smash it to pieces with a chisel 😂
haha yeah I lost that in the edit, it wasn't that exciting
I really didn't expect that spring compressor to hold up. 👍
Badger, I found this on my news feed, it just randomly popped up....But I love Morris Minor, used to ride in it many many years ago!!! But didn't watch this one until I've watched part 1, 2, 3, 4, 5, 6, 7, 8 first then now Im on 9....
For some weird reason. I really like Morris Minor. Lol. I love that little tiny engine....I'm gonna subscribe and then continue watch the series :) many thumbs up from me.
1,000cc, hmmmm....I could put that in a motorcycle frame. Anyway, it all reminds me of when I overhauled my Pinto wagon. It was a simple overhead cam engine with worn cam lobes. I got it all cleaned and machined and added new parts when needed. When it came to starting it I left the tail pipe off, just in case. I put a dab of gas in the carb, sat in the car and said, "Well, here goes." I turned the key and heard this LOUD noise! It started right off, I barely heard the starter, so it surprised me! LOL Scared the crap out of me. Keep up the good work. Don't think I'll try that other valve compressor. Just used to the old standard tool.
It's amazing how loud things are without headers and an exhaust. I learned the hard way too with my VW!. Cheers, I think that compressor is destined for the bin.
came for the moggie and intend to stay for the entertainment, cheers mate :)
Awesome. Thanks for watching!
I can't believe how lucky I am to have stumbled across this series. Just starting out with my own Morrie Thou project. Will be following you very closely and dare I say learning from any mistakes you make (very few by the way:-))
Unless you are going to do high mileage or wanting a racing engine, both of which I doubt you do not need to go to the expense of hardened valve seats. The little A series will run quite happily on unleaded. I have rebuilt several of these heads over the years and never had a problem. Are spares available over in Australia? I am in the UK and most parts are still easy to come by. Great channel by the way.
I'm not planning on hardened valve seats. It's not a common upgrade in classics round here. There are a couple of local spares places but the best range is from the UK and shipping is reasonable. Thanks 😀
@@Badgertronix you really do not need to go down the hardened valve road my moggies run well on unleaded with no problems what so ever one of my cars has a fairly hotted up engine in her trust me she flies real good and all i put in her is unleaded and so far fine enjoying the videos nice to sit back and watch somone else doing the work
Having stripped and rebuilt many many.A series engines,I can tell you with some certainty,that the valve guides will be worn as will the valve guide seals.You will have to replace both.A little tip for you,don't buy cheap valve seals,they last maybe a couple of hundred miles if your lucky, buy genuine,they are still available as are new valves.Nice video by the way.
I have a great parts guy so I'll be getting the right stuff to get this motor going. Cheers
After some backyard modification that little compressor did the job well enough. The head etc looks not to bad considering its age and your cleaning fluid is fine just filter the crap out then it's good for a few more washes lol.
It seems to be in reasonable condition. I need to first the junk out of the parts washer, the pump is not a fan!
Congrats on 5k subs. 👍👍
Thanks buddy 😎
The little engine that could... will, I should say! =)
Hopefully it will.... Or I'll have to VR6 swap it... Maybe hopefully it won't 🤣🤣
I have never known a 948 cc A series burn out a No1 exhaust valve, It was nearly always No3. I think this head has had some repairs done to it judging by the condition of the other seats at this mileage. Fit some double valve springs, new valves and guides when you rebuild it.
I hear it's not that common but it's what happened. I don't know too much on the history but I don't think it had a lot of work done
Brilliant video thank u 👍👍👍👍👍👍👍😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
Throw that valve spring compressor in the dust bin! Get a good quality used one from eBay or somewhere else, after all you will need a good compressor to reinstall the springs.
I have a replacement on the way
Looks almost perfect 👍 Like the big parts washer , I have to get one too. Cheers
It's for washing your big parts 🤣
Badgertronix Dirty boy, go to your room!
If you have a pillar drill, put the valves in the chuck, and use a wire brush to clean them, a little WD40 helps too
Cheers for the tip
a lot of love went into building the moggy thousand even the head has 4 hearts
Haha so it has
Some soft NZ rain eh? Sounds great. Spring tool seems a bit minted though.
Yoy have to clip under that base of the spring, not half way along it. Then you full compression of the thread.
That’s probably the most useless valve spring compressor I’ve ever seen turned a five minute job into a marathon.
You're lucky I edited out most of the struggle out. That thing wasn't very useful
Just found your channel. Are you going to grind all the valves in your next video? I’d repaint the engine in BMC / MOWOG green as I did on my 66 Mini and it will look fantastic! Keep the videos coming. 👍🏻
Next video I'll continue stripping the engine block. Then after that I'll build it back up. It will be getting a coat of green paint 😀
great video keep it up it motivates me to start a project up dont worry about the key board worriers, doug from wanganui.
Plenty of satisfaction in doing projects like this. Let me know what project you find
had a 57 humber hawke a few years ago fixed it up had plenty of rust in the doors and around the boot plus frozen up brakes lol that was a mission got it where i could drive it then sold it , i kicked myself after for saleing it im looking at a A50 panal van at this moment .
skip the valve compressor tool and use use a socket and a mini sledge. one tap and the retainers pop out. reinstallation may require a tool
You gotta be in Sydney if you got rain, dont be gready send some south.
New Zealand, just out of Christchurch. We've been on water restrictions for months so it's welcome but the timing sucked
Best to go down the path and get hardened valve seats for lead free unleaded fuel?
That's a great point of debate 🤔
Love your videos ! Looks like a great project car . What year is it .
Thanks! It's a 1958 I believe
I used a c clamp type valve compressor bought from SCA on a 2.25 Rover engine and it buckled after a couple of tries
I'll get the revised SCA one an see how that goes. Cheers
No worries. At least they took it back, i ended up getting a much meatier version from Repco at about $160. Cheers
i have the same type valve compressor Does the job in a fraction of the time it took this poor guy to do it with that crappy tool he had So much for progress !!!!
"Revolutionary new tool demonstrated by increasingly frustrated mechanic"
Haha
Enjoying ur vids. Was wondering if ur in the Sth Island N.Z.? Hearing u say 'wee bit and hearing the birds , thought maybe they were Keas? Or ur in Aussie.from England
Toss the collets in a magnetic dish, lose one & you'll be really pissed. Before you use the compresser, give the valve spring retainer a whack, this loosens the collets & they come out easy. Oh, so you did LOL Your magnet is a good un.
nice work mr c its cleaning up nice and the name for the top of the spring is a do dar lol gongrats too on 5k subs well done buddy
Thanks mate. Haha I think you're right
I've never seen a valve spring compressor like that before, and after watching this I don't want to ever see one of them again !!
So why would one valve burn like that ??
You and me both although to be fair it does serve a purpose. I'm not too sure on why the valve would burn like that. I'll have to do some research
If your valve clearance is too tight, the valve can't seat properly, and it will burn out. Otherwise, a piece of carbon can get stuck between the valve and valve seat, which will also cause the valve to burn.
Excellent! Thank you.
Thanks
Im a bit of a noob, while this is really satifying to watch and ive loved the series so far, what does this actually achieve? Will it perform more efficiently?
Woohoo 1st!. Love this car, keep up the good work
Welcome back and thanks for watching
Was that spring compressor cheap? I've only ever seen and used the type shaped like a G cramp that reaches onto the valve's lower face. Fast, effective and strong enough to separate the collets from the bidda medal.
Fairly cheap. I got that one over the g clamp type as they're not that common on TH-cam. I'll get a better one for the reassembly....
@@Badgertronix They're a LOT more fun to use.You can squeeze the spring right down.In fact you have to grease the collets and stick em to the valve or they tend to fall into the taper too far.Another thing to check is the pressure face of the rockers.They get recessed and make for tricky clearance setting. I miss fixing engines......
I agree it's the type I've always used, the one in the video looks cheap and nasty. Did the job though.
Was wondering if you lapped those valves?
I was going to say something derogatory about the valve spring compressor, but everyone else beat me to it 😂😂😂😂😂
I think there is still time to further verbally abuse it 😂
Excellent , i have qustion what is the best way to clean the catalistic converter in my car golf 3 1.8 L ?
Great job as usual Jonathan! Loving the music! Kinda like 70's disco porn if there is such a thing? 👍😂😂
Thanks Niamh. I'm not going to Google it to find out 🤣😂
Why valve spring compressor easiest way is old spark plug socket and hammer
Yep, surprised you didn't do this to rip them out, then use a decent compressor to refit them.......xx
👍👍
😀
You don't need to change the fluid in your parts washer until it's so dark it sucks all the light out of the room... ;)
Burn exhaust valve? Nonsense! Morris just had a variable compression and dynamic airflow system 50 years before anyone else!
For goodness' sakes, you've got two kids, Jonathan! Get your respirator on when you're scraping, and work wet! I have it on good authority that asbestosis is rather unpleasant. :(
The pump is struggling with the big chunks, I think it needs filtering at least.
The British car is ahead of its time. They went bust years before anyone else 🤣🤣
Fair point. Full body suit, respirator and helmet from now on
That valve spring compressor is a bout as usefull as a handbreak in a cannoo😂😂
Haha that sums it up nicely
Is the 948cc A Series engine a non interference engine?
I have no idea. I presume it is
Has it been converted to run on unleaded fuel .🤪😳🤪
How much would you charge to rebuild a morris engine
Won't you replace the valve seats ?
Up for debate, but probably not
Badgertronix the molten ones ?
Hi there,, watching you use that tool was painful, next time just use a 15-17 mm socket and a hammer, job done in minutes , still, ,,, moggies forever
It was painful using it!
What did everybody go ta bed?
Gotta get ya a new chair.
Good job.
I need a new chair, new tools, new haircut. Thanks buddy
@@Badgertronix New tools? What new tools? Have a great day mate.
17:34 holy shit mate thats some reckless flying, rotten basterd flew right through yer shop
haha they're everywhere
Did you know a bumblebee can travel at 70 miles per hour . If it's stuck in a car radiator. Ha Ha just saying
that compresser is a safety hazard
You could have just used a deep socket and hammer to strip out the valves, was painful watching you using that useless tool.
You really should’ve worn gloves
I see what you did there
