Engine Rebuild for the 1967 Alfa Romeo Spider project. 

Never was an Alfa engine assembled at the factory with such care!

I understand now why you haven't had much time to make videos recently! BTW Jethro, I find the calmness and precision of your assembly videos to be very therapeutic. A true engineer. Great to ease any stress!

These videos are so calming for me. It's like anti anxiety medicine for the alfa lover

Nice film quality and editing.👍

Superb! Single click only when torquing. Remember the law of friction. A solid object moving against another solid object has less friction the faster it moves. The maximum friction occurs right before it’s put into motion. So, when using a torque wrench, the nut or bolt is in motion when it reaches the desired force causing the wrench to click, which means it clicked with less friction. When you go for the second click, it takes more force to put the nut or bolt in motion than when you reached your desired torque the first time. If you go for a second click just to make sure, you are not double checking the torque, but instead you’re just risking exceeding the torque you already achieved. One ping only Vasily!

my neighbor in Johannesburg had an alpha spider of the same generation(don't remember which year) and that was the car that got me into car culture.

Hello I am just coming to the end of my nut and bolt restoration on my 1967 Alfa Romeo Zagato which has the same engine as this one. This video has been a great help with my rebuild of my engine, so thankyou for taking the time to do this video.

So underrated channel

Beautiful to watch. Like a surgeon.... Can't wait till you fire it up. Looking forward to it. Thanks

Fantastic. Better than new.

Best tool porn ever! Seriously, your videos are a most wonderful life lesson. You begin with a desire to save a bit of history as an honor to those who built it. You put your all into it and get hit with an unknown, very bad problem. This hurts, after so much hard work. Most people stop here. They are spent, hurt, exhausted. Did Jethro stop? NO, this is where you shine. You re-group your thoughts, pause to recharge and formulate a better plan with the additional information you now have. The new diagnosis was brilliant. It was but one flaw that caused all the issues with the engine. Once you knew that, you charged on with even more confidence. The way you turn bad into good is so beautiful, a life-lesson very much needed in these hard times. Thank You Sir!

I wish I could do any of that- nicely done! I also like that this is not a stupid engine swap- the original engines are a huge part of what makes these cars fun and you really do not need 300hp for that.

Nice job Jethro. In 1969 I had a 1965 Julia veloce with a blown head gasket. My dad milled the head and valve shims for proper clearance on our back porch.He just happened to have a Bridgeport. Ha Ha

Beautiful work

Beautiful work 👌

Jethro - NASA is calling you. Total precision. Brilliant. Best wishes Mark

Congratulation for the beautiful work!! I love your videos they are really informative and detailed.

That was immensely enjoyable to watch. Glad to see you are making videos again

You've out done yourself Jethro! The video was so detailed. It was blast to watch!

Great work. I watch these over and over for the time I need to work on my 82 alfa

Nicely Done. The 105 engine is a lovely, lightweight, infinitely rebuildable work of engineering art.

Well done this video and the competence are second to no one!!

That was great...thanks for sharing your experience

Nice reference to getting the con rods in the right way round by the way. If only we had RU-vid in the 80's.😃

What a delight watching you work. Thanks so much for sharing your knowledge, I know doing all your videos makes any project take that much longer. Bravo !! Marc. Western Australia.

More very high quality content Jethro. I have the same Seiko Diver watch although your strap game is strong :-)

The only problem with Jethro's channel is that everytime you watch a new video, there is this consistant feeling of never having enough of it and wanting more. I feel bad seeing how much work he's doing ^^ anyway, it was a fantastic video, it was sush a pleasure to watch this engin being rebuilt and somehow upgraded. It will run bettter than ever before. I can't wait to watch this Duetto spider running back on the roads! Keep the Great work. I can't get enough of your content !

Editing is up there with the best Jethro! And your dedication to precision engineering of these parts - they come together seamlessly. Satisfying and informative content!

I've gone through two engine rebuilds/renovations on my Series II 1750 GTV...I knew nothing about engines before...I didnt do the work on my own but I learned so much by being a part of it...this video so elegantly details how everything fits together and why. I would like to try my hand at a rebuild like this on my own now...The 105 Alfa Manual is actually really comprehensive, but what Jethro adds here are all his know how and tricks that only come with experience.

You have the best Alfa Channel out there. Keep the videos coming!

Beautiful video of a beautifully executed build!

VERY VERY = nice always loved these alfas and twin cam engines !

For us that had a real theraputic vibe to it. It was a true symphony of parts with Jethro as the conductor. Thanks from Sydney, Aus

Just watched this video. First one from your Chanel. Really enjoyed it, was actually very relaxing. Enjoyed the laid back narration and lack of cheesy music. Excellent camera work also. Well done.

It has to be the most aesthetically pleasing of engines.

Jethro...l'm sitting here in complete focus watching your video....this video is for the how to, and should do.... My complement on your effort, and believe me it's not in vein. We sometimes in life fall into a situation that requires a reset. Thus is this 105 motor... A reset that establishes your future out here in the real world. Normally I would have questions after watching you.....but today I have a big smile on my face, and trying to come up with the proper compliments to give to you. Honestly your video is by all means a compliment to you..... Well done, hopefully you can provide a vid on the install and subsequent startup. Your efforts require the respect from all Alfa enthusiast out there... For sure you got mines....

I can’t believe you lovingly caressed that engine back to life with such love and care right in front of that poor Giulia ti in the background. How she must long for the Jethro touch. 😉 Great work, I love it. You put so much care and attention to detail into your work. It’s admirable.

Can't wait to see you driving this one. :)

I was hoping you would release a new video on this project. Congratulations on finally getting the engine finished. Thank you for sharing!

Hi Jethro, really enjoy your channel and the way you approach adversities in the workshop. I've had several 105s for over 40 years now and one recurring thing I could never really sort out 100% was transmission vibrations. As you know the 105 driveline consists of many elements and they all need to be perfectly in line and balanced to have a totally smooth transmission. Maybe you can do a video about that one day. Thanks and keep up the great work.

Meticulous work. Lovely to watch

I just want people to have in mind that alongside the big job of assembling that engine you also had the big job of editing this video to look this good. Hats off to you, good man.

Very Nice Light 👍 in the video

This video is a work of art!!!!

Another lovely video. It's inspiring and at the same time soothing to watch. Thank you Jethro

Thanks Jethro.

video and engine both works of art. stunning

Nicely done Jethro - there must have been moments when the 1600 engine's life was under threat, but thanks to your perseverance, precision and skill looks as though this Spider is going to have great original engine.

Waaaaaw, congratulations, nice work!!!!!! Greetings from Belgium, an Alfa fan!

Absolutely excellent piece of work here - in terms of the shots and editing, as well as the engine assembly. I am so glad that RU-vid algorithm brought me here couple months ago. Keep up the great work!

Boy oh boy, does that ever bring back memories of my '66 Giulia Spyder's motor that I rebuilt 42 years ago! Superb power to weight ratio. A very enjoyable engine to work on.

In 1971 I purchased an Alfa Romeo Giulia 1300 TI super. They were exceptional cars, their uniqueness was the sound of the engine, (my wife knew when I was parked at home) the acceleration, the cornering stability and when she accelerated the rear axle she rocked right left. I was 26 years old. After 32 years (I sold it in 2003) and after at least two restorations it didn't behave like this anymore. I have the road tests and the comments of the Quattroruote magazine and the Motor Books Alfa Romeo Giulia 1962-78. You did a perfect competition restoration with impeccable care. I would like to drive it again with the scent of the new car and the scent of rubber and leather. Thanks for the video.

Hi Jethro, i can feel the struggle. Had some great difficulties with 105 engines myself the last couple of months. I think your approach to building engines is great. Making sure everything is super clean and to spec so it's all like new. Keep up the good work

These are not problems, they are wonderful opportunities that you are handling brilliantly. These cars are incredibly under-appreciated. But those in the know, know.

im so hyped to have a south africa based car youtuber. im so exited keep it up, the build is so awesome.

Awesome mate. Your videos are top notch. Thanks for doing these, I'm learning a lot from them. Cheers👍👌

This is amazing, like watching a swiss watchmaker assembling a watch. Great video!

You can easily fit piston rings by using a stiff feeler gauge held vertically beneath the ring, then gently rotated as the ring is eased downwards.

Jethro, thanks for that build. I decided not to go ahead with my Super 1600 resto as I came to the realisation before I started that I couldn't do it justice. The body shell had little rust and I had enough spare parts for the interior, engine etc but a long term project without a full size garage would have risked the car. It's therefore great to see a thorough and conscientious build.

Thanks Jethro for putting together such a great production ,,,I admire your patience with this engine and hope all goes well,,You have also increased my confidence level greatly in terms of opening up my 2000.

Fantastic channel. Well shot and narrated. Love the old Alphas. Had an ‘84 spider, wish I still did.

Great work man impresive

I always think that watching Jethro at work must have been like watching Michelangelo paint...so much care, so much precision... it's like therapy

Outstanding video Jethro. Thank you for the education!

This is a well done video. The engine detail is excellent. The 20 min went by unnoticed of time passing. Thanks for not putting in crap childish music that ruins videos. This engine should run like a Swiss watch. Looking forward to the engine run.

You nailed, video is amazing with so many details, I'm really enjoy to watch.

Everyone else has already said it all in the comments. But it's worth repeating in your case. Your work and video production is art!

I like the orange band on your Seiko diver. Good taste. Not only with cars. 😉👍

Beautiful cars and engines. You can tell they cared how everything looked.

I absolutely love watching your videos. So precise and informative and very engaging as well as calming. Looking forward to the next instalment. Keep up the great work.

Thank you for the update, I am so looking forward to the first start and drive of this Alfa. Your attention to detail is off the chart, I would be proud to own a car your have rebuilt. Keep up the good work.

That editing tho, ASMR for full grown men. Top work my friend, you should be more famous.

So clean, so precise not only in mechanics but camera work and editing. Are you some kind of benevolent psychopath? 🤔

Great work, really love it. Keep it up.

I pretty sure I will never find video so chill like this one 🌀

People are saying that Alfa Remeo is a piece of art but i think this video is piece of art as well

this video is pure art

New to your channel and really impressed. Will definitely subscribe as soon as I finish posting this. You have no idea how nice it is to watch one of these videos without a lot of insipid music, unnecessary braggaducio and self-aggrandizing dialogue. I had several of these cars when I was young and really wish that you were my brother then.

A lot of careful planning! Great job.

Thanks for the update and I look forward to seeing the transmission assembly.

A nice comprehensive build with attention to detail. I'm putting my fresh rebuilt motor into my 73 GTV today. Thank You

These are just brilliant videos. Totally absorbing. Your forensic approach is matched by your surgeon like assembly of the component parts.

Great work as usual. I loved the episode and cannot wait to see the engine running. Really interesting to see the differences and similarities between these Alfa engines and the old mini engines.

I don’t think I’ve ever enjoyed watching a video of an engine rebuild more than this. The precision, care, attention to detail and the calmness to your work is really admirable. I would pay anything to ship my 1969 Duetto 1750 to South Africa and watch you rebuild it.

Excellent video!!!!! Thank you sir

The King of Cool rebuilds an engine in a white t-shirt & sneakers!

I used to use Plastigage to check main and con rid clearances..takes more time, but you know FOR SURE, that clearances are spot on

Great professional build....

Absolutely brilliant, loved it, pitched really well, edited superbly - brilliant work! Can’t wait for the start up! Stay safe, stay well...

Absolutely fantastic work. Wish I could learn mechanics from someone as patient and thorough as you!! Hmm, sounds like a business idea :)

Awesome sound quality

Awesome, loved watching this Jethro, if I could like it twice I would

You may want to re think using high temp gasket maker everywhere. Ultra black from permatex is excellent in both adhesion and stopping oil leaks. High heat silicone is good for basically exhaust manifolds. That's it, it's not made for anywhere else. Case sealer for two strokes is also another amazing product for stoping oil leaks

You did a very good job!!! Bravissimo! 🍀🍀🍀

A++ man. Keep the videos flowing!

Excellent work Jethro. If she runs as good as she looks, your in for a real smooth engine.

This so soothing to watch. Thank you.

Excellent work very clean and very neat. well done.

Epic build !

just finished a 1600 "racing" with lots of Alfaholics parts, an adventure ... can be very tricky indeed !! this video is really relieving ;-)
