- Stay awhile and enjoy a slice of fabricobbler- we’re serving up homemade engine parts today! There are a few loose ends from the cooling tin refurb to tie up, then we attempt to recreate the old heat riser tubes that were hacked off in the past. This part is important because it keeps the engine running smooth by delivering a little warmth to the coldest part of the intake manifold. I don’t know, thermodynamics or something. The cooling tin needs a few holes cut and closed too, so come on in and have a heapin’ helpin’ of our home shop hackery!
Much of what we use is linked below - Check it out and get equipped!
Please make an effort to thank someone who is on the front lines of this national crisis. If that is you, thanks for being here for the rest of us, and please stay safe!

And you have created world's most expensive back tin. 👍👍👍👍
Sold! Hey Agramer Old Octane, thanks for checking out the video! This thing is made from scraps, but if we consider time and welding wire valuable, I'm thinking you've got a good point...
Fantastic attention to detail.
I do remember, back in the day, driving on 95s in Florida, on a 100+ degree day, in a traffic jam, that my old 63 ghia was one of the few cars that wasn't overheating.
I don't believe it's inherent in the beast!!
I'm learning more about Vilkswagen engines and to maintenance them
Aircooled engines are unique very simple to operate keep up the work
I agree Kevin, these little engines are fascinating. Thanks for watching!
On the night the Titanic struck the iceberg, I can see you running down the lower decks with a hammer, torch, and anvil yelling "Don't worry, I can fix it!" :) Great vid as always!
That's awesome! Oh, wait a second... that boat sank...
Just kidding, thanks for the kind thoughts and for checking out the video, it's always great to have you here!
🤣🤣🤣
This comes about a year late. When you go to bending your EMT fill it tight with sand and cap or seal the ends then you can easily bend any degree of radius you want without the tube collapsing. This is an old trick and works well with most any thin wall tube. You do an amazing job and I am inspired by your work. As I am building a 1968cc engine for my 1974 beetle I will most likely "Try" and be as detail oriented as you with my cooling.
Great tip Todd! Not too late at all- I'm sure this will be helpful with a future project and I look forward to trying my hand at it. Good luck with the '74 power plant- every little detail counts and I'm sure that 1968cc will have many happy miles ahead. Keep us updated!
Lovin the optimism and experimentation 👍
Cool approach; with OEM engine tin becoming more and more scarce by the second this might be all we are left with; adjusting aftermarket tin to make it work.
I agree Ricardo. I was reassured to find plenty of OEM tin at a recent swap meet, but when it's gone, it's gone. Thanks for checking out the video!
Your like a Bob Ross of VW 👨🏼🎨
That's awesome, thanks for the generous compliment. I'm pretty sure I've said that about VWnut1967 before but I'm happy to be on the receiving end this time. Thanks for watching Mr. MOTORMASTER!
@@HapticGarage THANK YOU for the great videos 👍😎
Well the last thing I’d ever say about you is that you have no idea what you are doing or that you are clueless!! I love your persistence (check out what Calvin Coolidge had to say about that) to turn this crappie aftermarket tinwear into a “silk purse”. The obvious question was “why do it”, but the video transcended the obvious and took us to a place where the important message was about the use and application of skills, just for sake of skills. I really enjoyed the video and love your dedication to improving the ordinary, just because you can. Always look forward to the next instalment.
Hey Aussie Beatle, thanks for the wonderfully thoughtful comment. That's a great quote from Coolidge- he was on to something about determination vs. other desirable attributes. I appreciate your insightful interpretation of what was presented here, and thanks as always for being a part of the channel!
Haptic Garage being part of the channel is easy . I love it. A smart guy with great skills, cool equipment with a passion for VW all packaged brilliantly. It’s gold.
In my dream world, the people at the aftermarket tin factory watch this and make some minor but crucial adjustments.
Really nice work as always!
What a great dream world you've described Dream Wrench! I'm going to go about my day today believing it can happen. Thanks for always being here and I'm looking forward to your next update on the squareback!
Cool video show cases your creative talent and skill which are over top, this is getting to be a lost art in today's world of plug and play..thanks you..
Hey Dan, thanks for all the positivity and support, it's always great to hear from you. I hope all is well up north; I bet y'all are preparing for fall and getting some nice temps right now. Thanks for checking out the video!
Your a madman! This is super entertaining to watch. I’ve pitched so many cheap tins over the years maybe I could of made them work out after all🤷🏻♂️crafty is an understatement. Brilliant work.
Thanks Vdub618, what an awesome comment! It's a toss up; it seems the cheap tin can be saved but not sure it would always make sense to bother with it- just depends on the circumstances I guess. For this project, it's been the thing to do but the next project with have it's own evaluation! Keep up your good work on that '69 Beetle (what a great year) and thanks for being here!
Holy geez never seen one try this before. It was sure fun to watch but glad it was you and not me 😁
Hey Joshua! Yeah, a swap meet would've given me better options but it ended up being a lot of fun this way. Thanks for checking out the video, it's great to see your comments as you catch up on the series!
Inspiring me to get going on my own 71 bug I have had since I was 20. Just celebrated my 50th so it’s about time. Thanks for spending the time to share this with us and for your great view on fixing things the hard way, cause it’s cool.
Oh wow Stacey, this is beyond awesome. You've got me beat but I'm close- I've had Dweezil about 25 years and feel the same way. There's something really cool about maintaining hope for a project as the years click by. I hope you're able to make it happen and would love to hear about your progress. Good luck with the '71 (awesome year by the way) and let us know how it goes!
I was so glad to see an update! The fabbed heat riser turned out great! I'm not sure I would have thought to go that route. I love that you're sticking with the "run what you brung" build. Keep it up!
Thanks for being here for it Adam, I appreciate the support! The approach has been half the fun of this project; I'm glad you're enjoying it!
Great video.I love that you repurpose things .Inspirational a bad day in the shed is always better than a good day at work.Cheers from Australia.Ruby Red 61 deluxe.
That's a quotable comment matt zander, gotta say I can relate! I hope all is well with you and that sweet '61, thanks for checking out the video!
I love how you used what you had and made it all work, excellent job as always!
Thanks VWJawbreaker, this was a fun project. Thanks for the support and hope to hang out again soon!
Haptic Garage were definitely overdue to hang out. Hopefully soon we can get together and get some work done.
Yeah man, not sure how neighbors will like it but sounds good to me!
I had some much fun just watching you in your termination of making things fit correctly.
Thanks again Christopher- this was a fun project to do and share, I'm glad you enjoyed it!
The tools in your hands that enhance the skill to make every WV rev up
The magic is vandemic
I'm glad you're enjoying the videos, Kevin. Thanks for the positive comments and support!
Wow, great job. You know your way around sheet metal.
Hey Vintage 76, thanks for the props! We've had good luck with the sheet metal on this project- really looking forward to some challenging body work on Dweezil. Thanks for checking out the video!
Quality work again !! Resto work should be fun and enjoyable and you nailed it thanks for sharing
Thanks vwcoco, it's always great to hear from you. I agree completely- this should be fun! Part of that is recognizing opportunities in the face of adversity and keeping the journey in focus. Thanks for being here and continued good luck with your impressive VW fleet!
Absolutely amazing and a whole lot of fun to !
Thanks Neal, I'm glad you enjoyed it. Thanks for being a part of the fun!
You really did a great job I am a firm believer in proper cooling of my 67 beetle and will be upgrading it to a 1915 motor I was impressed with your visor and learned a lot great info thanks .
Thanks Christopher! You are correct to focus on cooling with the 1915 upgrade- it will make more power so it will also make more heat. Good luck with the project and let us know how it goes!
Impressive work on the heat riser and conduit solution. Thx.
Thanks Mra Mra. I was a little concerned it would burn out but so far, so good!
I found your channel about a month ago from watching Vwjawbreaker and watched every video. I have been looking forward to another video and you did not disappoint. I wish I had a fraction of your patience.
Hey 75 RatBug, it's great to have you with us. VWJawbreaker posts some cool stuff and that '60 bug project he just started should be a lot of fun. Thanks so much for checking out all the videos, I'm glad you've been enjoying the channel and we'll do our best to keep it up!
Not alot of help in the air cooled world where i live so even the smallest details, even if they seem obvious, helps me so much. You explained how and the flow of the heat riser tube. Thanks again for a fun and informative video!!
Hey Benjie, thanks so much for the positive feedback. I'm always curious how different elements of a video will be received; it's good to hear some of the information is coming across and has value. Just remember you're not alone when working on your Vdub- we're part of a great community and it's great to have you here!
Cool video mate👌👌
Thanks SixFix, glad to have you here!
Hi, just found your channel, love what your doing, keep up the good work. I wish I had your patience.
Hello a080867, welcome to the channel. Thanks for the nice comment and for checking out the video, more to come!
I love your shop, makes working on stuff like this so enjoyable. I have a back yard and a shed and I am exposed to the elements, no bueno. Awesome content, thanks for all the fun edits, it makes it really fun to watch, you are very handy.
Thanks Skater Stimm! For sure, working on a vehicle outside can make things more difficult. The Moseyhome (the Airstream motorhome in some of the other videos) won't fit inside so sand and sun play staring roles in that project. But where there's a will there's a way so a big thumbs up to you for getting it done despite the challenges. Thanks for the support and for being a part of the channel!
good progress!
Thanks VW Life, it's great to be moving forward!
Another well done production. Tig cameos are always special. Interesting, well explained, and informative.
Thanks Ken, I knew you'd like Tig's cameo. We need to get you in one of these state of the art Vdubs.
Really good video, I appreciate your hard work. I had to repair a dual heat riser manifold for my 74 super beetle.
Thanks Jeff! I hope the repair went well; as I'm sure you know, it's a task worth doing for a center mounted carb. Thanks for watching!
Is that a new Jet Brake I see? 😀
Hey Rob! I scored that in an auction last year. Some of the fingers are a dinged up, but no complaints.
👍
Thanks Katmandu!
Great episode. I love how you explain everything you are doing. Great work.
Thanks Dennis, I could talk about this stuff all day. I enjoyed your conversation with @GoodOldMike on his podcast and look forward to seeing more of your channel. Keep it up!
The tite fit makes a big difference on the hottest days.
Absolutely hey you, we've got a lot of those here! Thanks for checking out the video.
Glad to see a new video! This one brings back memories for me, I spent a bunch of time fiddling with the ones on my bug, a combination on original tin and crappy repro stuff. But like you, I manage to made it all work. The bug stays cool(ish). Great video, as usual! Cheers!
Thanks Nutt Farm Garage, it was great to post again after a short hiatus. I'm glad you got the tin sorted out on your ride- it's time consuming but worth it! Thanks for the support, it's good to hear from you!
usually with a clogged carb heating, people cut open the lead and replace the whole pipe..
Hey Chris! I've cleaned one through a rusted out hole in the bend before but haven't tried slicing the aluminum to replace the entire pipe. It would need to be welded back together once the new pipe was in to conduct heat to the intake. That's reason #1,739,214 for me to learn aluminum welding... Thanks for watching!
when doing such custom work, stainless material worth the investment, usually, grade 304 is OK.
Hello Jacques Poirier, thanks for the suggestion. Stainless would have been a great material for this! I've used it before but need to choose a project to increase my familiarity with welding that material. I'll keep it in mind for the next exhaust project. Thanks for checking out the video!
Had a 1968 beetle with a clogged heat riser - but I didn't know it was clogged. 68 - each cylinder head had a single port, and engine a 1-piece intake manifold with attached heat riser. Did the engine run without the heat riser? Well, mostly it ran fine. But now and then it had a "flat-spot" during acceleration. While accelerating it would suddenly reach a point where it would not accelerate any more. Then after a moment or 2 it would accelerate again - as if the fuel had stopped flowing for a second, and then began to flow again. I had just completely rebuilt the engine but I had neglected to check if the heat riser was patent. Why wasn't the fuel flowing? Why on earth was the engine having a flat spot? I couldn't find anything wrong with the fuel pump or the carburetor. Engine worked fine when the car was stationary. Problem was only when the car was accelerating, when the engine was pushing a load. My customer was sort of pissed! Just paid me a lot of money for a complete rebuild - why was my car hesitating now and then she wanted to know. After about a year of this I finally figured out what was wrong. I must have read about it somewhere, but I don't remember where. This was before the internet. It was about 1978. When pushing a load lots of fuel and air was needed to bring up the rpm - more than when the engine car was stationery - and the high flow of fuel-air mixture was causing water vapor from the air to freeze as it flowed through in the intake manifold. This caused the mixture to stop flowing for a moment, caused the acceleration to "hesitate," and then a moment later the ice melted and the engine continued going faster. So I took off the the intake manifold, propped it up, upside down, and poured carb cleaner into the heat riser. Let it sit for a few days. Poked it with a wire coat hanger every once in awhile. Finally got a "breakthrough." Once I got a breakthrough clearing out the heat riser proceeded faster. Kept on poking with the wire hanger until the passageway widened and widened, until it was almost as wide as a new one. Put the manifold back on the car. Car ran well. No more hesitation. You need to have a working heat riser! I don't think the Bentley service manual said check the heat riser, before attaching the intake manifold to the cylinder heads and the muffler. I think that's why I didn't check it. Next rebuild I checked! And checked the oil passages in the crankcase, too.
Hello Ready Teddy, thanks so much for sharing this awesome story! It's great that you stuck with it and finally figured out the issue- I bet you and your customer were happy with the result. And yes, the oil passages are easy to overlook too... Thanks for watching!
1st comment!
Woohoo! Hey Levi!
You commented first but I watched the entire video 😂
@@VWJawbreaker Spoken like a hard working UA-camr!
Trying to restore 1961 40 horse but cannot find front and rear tins. Any suggestions? I enjoy your delivery and content.
Thanks Joe! My first choice would be finding used original tins at a swap meet. As you saw in the video, aftermarket tins (when available) need attention even when new- so the effort may be better spent refurbishing original tins. Last choice for practical purposes would be to modify the closest thing you can find to perform the same function as originally designed. However it turns out, it will be worth doing! Thanks for the question!
He would have accidentally fixed the titanic to a modern cruise liner. Made a time machine out of a deloreon etc.etc
Aw schucks lpz, too kind. Thanks for watching!
Are you using flux core wire??
Hello Brian, I'm using the usual non-flux core ER-70S and 75/25 shielding gas.
So why put them on of the engine runs great as opposed to running like it should? Manifold support for carb?
Hi Raul! I'm not sure I fully understand your question, but I'll offer this opinion- a great running engine is running as it should. A single carb engine will run more efficiently with the heat riser in place (supports fuel/air atomization), which helps keep the engine running great over a longer lifespan. Your mention of the heat riser providing support is a great point; I've never considered that but it must strengthen the intake manifold, probably substantially. Thanks for the question!
@@HapticGarage So to simplify the question: Did the van come off the assembly line with a single or dual carb?
The issues I have with my single carb system is that it's running rich; plugs are dry but sooty black. I don't think I can jet it any smaller than the 127.5 main/55 idle that's in the carb now. I believe the manifold preheat system is the problem.
@@rjgarciasr Thanks for the clarification Raul. The stock configuration for this bus included a single carb with the heat riser. The heat is necessary to prevent the fuel from condensing in the manifold before it arrives in the combustion chamber. I live in a warm climate but that doesn't significantly change the thermal dynamics involved; I prefer to run the heat riser. Hopefully reinstalling the riser will help resolve your issue- I agree that those jets are on the small side of what many people run (unless I'm mistaken, I think those may be the stock sizes.)
@@HapticGarage Before commenting I had bought a used manifold because the exiting one was cracking where the risers meet the manifold, I cleaned it out before installing it. The manifold condensed below the carb whether it was idling at op-temp, or after a 20 min run. The high pressure side riser was about 165° F and the low pressure side was 110°, manifold below carb never got higher than an average of 115° after 4 runs.
I had installed new plugs before the first run. I took #1 out after the last run and it was dry, all black and sooty. The jets came in the new carb with spares of the same size. Thoughts?
Sorry for the delay Raul, I thought I had already replied to your question. I think condensation is normal in a humid environment; I see normally see that here in Central FL almost year-round. Based on your recognition of the high/low sides of the riser, I'm guessing you have an exhaust that is designed like the stock version to allow flow from the #2 stack to the outlet after #4. I'm currently running a buggy exhaust that just pings pressure back and forth without really working as intended, and it measures about 150° on both sides. This is a recipe for clogging! Anyway, it sounds like your riser is at least partially working which may indicate the rich condition and subsequent carbon fouling have a different cause. Too much choke? Float level? Needle/seat not sealing? Restrictive air filter? Just some thoughts. Please update with your conclusion, I'm sure there's something for me to learn here. Thanks for the follow up!
your not in Alaska you do not need heat tubes i live in Cali and my bug ran perfect its just more heat that will stay in the engine compartment
Thanks for your opinion- I'll agree that I'm not in Alaska! Thanks for watching!
But, do you "really" need heat risers in Florida?
Thanks for the question Jeff. I think the engine is better with the riser, even in FL. This place is hot, but the physics of an engine are on a different level. I use the same rationale for preferring to run a thermostat. To each their own, but heat risers and thermostats are right for me. Thanks again for being a part of the fun!
Next video??
Hey G! I'm overdue for the next Vandemic video but I can at least attest that it is coming. Thanks for checking out the series- it's been a great way to ride out the pandemic and meet a bunch of cool people here.
Yes, I'm always looking forward for tight tins and this videos are a peace of mind haha
By the way, love your beard my bearded friend..
Absolutely Bearded G,, a good snug fit for the cooling tins is the way to go!
Thanks, and same to you!
