As always, your video is entertaining and informative. I'll be starting this process on my '62 engine this summer. I'm certain that I too will be doing things twice. keep up the good work.

[@SealedBeamRallyTeam]

Best of luck with yours! It's work, but with everything powder coated, it's not that bad.

[@MrWaalkman]

It's coming along nicely. The powder coating came out great!

[@A_Litre_of_Farva]

I'm so grateful you make these super awesome videos. Showing your mistakes saves others from making them!! Thank you!

[@Fogmaster1990]

Hell yeah!!!

Since my first car, a 1.1 liter beetle, I have been a fan of rear engined aircooled cars. I lament the passing of this technology from the car world. so simple, no tail shaft, no radiator, no water pump, no water thermostat, so much less to go wrong especially as the car gets high mileage. I remember arrogant car magazine writers writing about the demise of the beetle in the 1970s claiming air cooled engines could not meet emission standards, yet, Porsche kept making aircooled 911s for anther twenty years! I live in Australia where the Corvair was never commercially sold though there are a number of privately imported Corvairs. I have just bought a non going 140 hp Corvair engine to rebuild (siezed from not being turned over for god knows how long, not sure what I will do with it yet once reconditioned though it may end up in a VW van, I very much appreciate this video cos I have so much to learn about Corvair engines.

[@SealedBeamRallyTeam]

Consider putting the engine in a dune buggy. It'll rip! Good luck with the project

[@bradsanderson9606]

Good job, a lot of work amazing how the engineers designed the shrouds for the corvair engine.

[@SealedBeamRallyTeam]

Really amazing, isn't it! There's a lot going on with this thing

[@spyderman1964]

I can send you those blower bearing bolts if you would like. I thought you had some parts motors now? Any chance they have what you need? You may need to install your muffler hanged before the side shrouds go on. You are doing great. As a guy I used to work with once said “how am I supposed to know what I don’t even know”. Words to live by.

[@SealedBeamRallyTeam]

I have bolts on the parts engines, but I will have to restore those bolts. I can't zinc coat metal yet. Could remove the rust and paint them. Looks like Clark's sells used bolts, but not restored ones. Considering just buying restored, zinc coated bolts online.

[@spyderman1964]

They are very odd bolts I don’t think they will be easy to find they have 3/8 heads. Let me look I think the ones I have are plated.

[@kimswansonlinner6889]

Oh my word, the lower head studs!!!

[@patcarbone1753]

You such a great job on that engine, really nice job!

[@crownmoldingbyspectaculart941]

Putting mine together tomorrow. The video on shrouds is real helpful for me. Been looking for something like this.

[@SealedBeamRallyTeam]

Definitely look through the comments, because there are a couple things I didn't know about! It's a process!

[@crownmoldingbyspectaculart941]

@@SealedBeamRallyTeam been watching videos for a while before undertaking this overhaul so I installed the shrouds in the cylinders before pushrods and pop riveted a cover plate on the blower shroud. Yours will be a pristine engine when done. I powder coated the blower shroud but I plan to paint the rest of the shrouds along with the engine bay body color.

[@Friedbrain11]

Where is the gasket between the shroud and the exhaust manifold at the outlet end of the exhaust manifold? It is an oval gasket. You'll wish you had run the engine before putting the shrouds on. You will need to retorque certain bolts and nuts afterwards and the nuts for the exhaust retainers will need to retorque:) Hahaha...you have the Frankenstein fan LOL

[@SealedBeamRallyTeam]

I was wondering if something should go there... Guess I will have an opportunity to install them later :) I planned on retorquing the heads, but exhaust would work too. Not that big of a deal... Now that I know how the shrouds go together!

[@JohnSmith-bh8um]

Man I live your videos. Just picked up 63 greenbrier with an extra motor. Sadly its missiing alot of parts and i dont have alot of money. It did however come with an extra 2.7 motor in which ill be rebuilding and selling help with restoration costs. Before i buy anything i need to make sure exactly what year engines i have.

[@SealedBeamRallyTeam]

Clarks has a really good couple pages on engine ID in their catalog (both online & paper copy). I used it to verify my own engine! Good luck with the Greenbrier. I've got a rough '62 GB i want to get running this year.

[@ricknorris6943corvair]

Here's a tip for next time. I always drill and tap all those small 10-32 screws holes out to a 1/4-20 size. Eliminates some complexity in fasteners.

[@SealedBeamRallyTeam]

Interesting idea

[@JohnSample-h6n]

There needs to be plastic or rubber inserts that can be fitted in Vice-Grips so when grabbing the push rod tubes you don’t scratch or crush them.

[@SealedBeamRallyTeam]

Or you can just be careful 🤓

[@MP2Tablet]

As far as push rods going back in order. As long as there's not a noticeable wear pattern, you're fine. Thousands of rebuilt engines over decades have run fine with push rods not going back in the same place, or not being from the same engine. Same for rockers and balls. Most problems come from dirty assembly. Not cleaning oil passages etc.

[@mkepler5861]

the powder coating can be sanded if the clearance is too tight.

[@timwerner7771]

At 37 :25 you mentioned the "Big hole in the front of the shroud I don't know what to do with". For what it is worth,...On my Corvairs i built a sheet metal cover and simply closed that off and did not install the oval air hose. This raises the volume and pressure of air coming from the fan and goiung down over the engine to cool it. You need as much cooling as you can get for this motor. You already have fresh air vents as well as defroster vents that work fine. Just my 2 cents.

[@SealedBeamRallyTeam]

Oh, I think I remember reading something about that modification. I will need all the heat I can get in the winter, so if it's a valve I can shut in the summer, that would be fine.

[@David-if2jz]

the hole the temp sensor goes in is a blind hole, no worries about it leaking oil

[@TairnKA]

I had a concept for a Corvair powered hot rod with the engine in front (rotated 180 degrees) and transaxle in back, but, additional to custom fabrication for the driveshaft, I see the vent (with doors) shrouds would also require a lot of modifications? ;-)

[@SealedBeamRallyTeam]

You'd be in for a lot of work. You'd also have to choose a transaxle- perhaps Porsche 944 or Corvette. I think the Corvair engine turned backward and hooked up to a normal transmission would spin the wheels the correct way...?

[@ercost60]

21:15 iirc that hole holds a grommet for your temp sender wire

[@ricknorris6943corvair]

Dang! Hurts me to see push rod tubes removed with ViseGrips! I have re-habbed many tubes booggered up with the wrong tool. Okay, I did the same back in my young and ignorant days when that was all I had.

[@SealedBeamRallyTeam]

Didn't pinch a one. I see Clark's has a pushrod tube removal tool now. Not sure it's worth it for doing just one engine.

[@royhedlund6920]

You might wanna be careful with that skid plate because if you block off too much of that undercarriage, the air won’t be able to go through as much and that’s the cooling of your vehicle because it’s not liquid cord Aaron needs to get from the top of the chassis through the bottom

[@SealedBeamRallyTeam]

Not much usable airflow down at the oil pan, even in stock form. It won't be tight against the pan either. But if I need extra cooling I can get a finned pan or external oil cooler!

[@keithad6485]

Does anyone know if a Corvair engine has ever been mated to a modern VW Transporter 7 speed auto? If yes, did it work ok? I own a T5 Transporter with a 7 speed auto and I love it. Probably warped thinking, but it occurred to me to fit a VW 7 speed auto to a corvair engine and fit it to a rear engine T3 VW Transporter.

[@SealedBeamRallyTeam]

I will bet you $100 no one has done this. I don't see why you would bother. The Corvair engine spins the opposite way that most transmissions were designed to work, so you will have to either reverse the rotation of the engine, or mount the transmission upside down. I've read that a Subaru 5-speed can be adapted and run upside down without issue. YMMV, but if I were looking for an overdrive trans, that's where I would start.

[@keithad6485]

Has anyone every fitted an electronic fuel injection system to a Corvair engine? If yes, how did this work out?

[@SealedBeamRallyTeam]

My sponsor Clark's Corvair Parts sells fuel injection kits. You can read all about them in the online catalog! Personally, I'll stick with the carbs.

[@keithad6485]

@@SealedBeamRallyTeam Thanks for the info. Fuel injection appeals cos of the better fuel economy.

[@SealedBeamRallyTeam]

@@keithad6485 Is this going to be a daily driver, or a weekend toy? The best way to save fuel is to drive less, and hobby cars usually don't see that many miles. Food for thought

[@sunfishensunfishen2271]

Green Saab??

[@SealedBeamRallyTeam]

Saving that for when the shrouds are done!

[@WAWZDAT]

@@SealedBeamRallyTeam I like watching most of your videos just for new wrenching ideas, but this was my big question. When, where, how on the Sonett story? Nice job on your engine rebuild. Looking great.

[@SealedBeamRallyTeam]

@@WAWZDAT When I was in college, I had an '81 VW Rabbit and was part of a euro car club. Another club member let me drive her Sonett. I had so much fun I vowed to buy one someday. Something like ten years later, my uncle told me he had one sitting in his yard and I could have it for free... that's the backstory in a nutshell.

[@WAWZDAT]

@@SealedBeamRallyTeam So, the green one was hers or your uncle's? Or was the purple one your uncle's?

[@SealedBeamRallyTeam]

@@WAWZDAT Purple was. I'll explain the green one in the future video
