Welding up water jackets on a 2JZ! Why!? How!? 

Wow, in my 30 years of life its the first time I hear of this. We learn every day 💪

in the first second of the video I thought he was speaking another language 'Haydeblakalii wahekeas "boneworks" today we're gonna talk about...'

Looks like you've got this process well-sorted. But a couple suggestions if I may be so presumptuous: 1. Rearrange the weld bench so the welder can sit comfortably rather than stand/hover over the work. Welding is always easier/better when the welder has good ergonomics. 2. Consider a bigger gas cup on the welding torch - one of the clear Pyrex ones really enhances the vision of the welder - allowing him to work better/faster/easier. 3. If you're not already, consider a welding power supply that can blend AC current with DC current. My Everlast 255ext does this and it makes welding on thick chunks of aluminum SOO much better. Everlast calls this feature "Advanced AC pulse". It really works great. 4. Try out using 4643 filler rod. It will naturally age (even without heat treatment) harder/stronger than typical 4043 rod will. It flows/welds/works about the same as 4043. 5. Rather than beating the weld with a ball peen hammer, consider trying a pneumatic needle gun. Gives 10X the effect of the ball peen, and does it 10X faster. I use this technique whenever I weld on cast-iron. Works great. Hope you don't take this as criticism of your already-proven work!

Awesome video as always man. Thanks heaps for making a library of quality info i can refer to if need be. You give me all the confidence in the world to weld on heads too. Thanks. Love from New Zealand to you max.

Bruce Lee said empty ur mind like water waterless heads can hold more pressure

Dave will always be my HERO!

Top.notch work👍

Beautiful welds

Have you tried spraying a little WD-40 On the deck surface before the finish cut? In my experience it will help prevent the cutter from galling the surface. I usually take a 5 tenths finish cut as well which usually helps with the RA and overall look. I have a feeling you already know all this and I'm wasting my breath. But I just mention it in hopes of helping. Awesome video as always Dave. On a side note do you guys ever bake cylinder heads there during the repair process to straighten them?

Nice video

It's always interesting knowing what makes the 2jz KING 👑💯⭐😎🏁🏁🏁

No cooling on the block...is this why you never see 1/4 mile cars driving anywhere but the track...thay would melt ...I love going fast but if I can't take it to pick my groceries up I'm not a fan

Good morning Dave find your technical details and information very insightful, I have been an engineer rebuilder since 1981 have you ever tried 4047 filler rod I always found the shrink back of 4043 put way too much tension in the casting would really like to hear your comments

It's the guy from law & order

The coming years are going to bring very interesting things to the car world... With 3D printing going where it is, it's not going to be long before the average joe can do a 3d scan and print their own parts out. Like scanning this head and filling in all the coolant jackets, and doing whatever else you could think of.

Hello Dave, today I have a question. It's not very clear to me (the translator makes things up) because once they apply the solder, they hit it with the hammer, why do they do this? Thank you. A great video as always. Regards Goyo

So Dave, with all this engine work you do at the shop… just wondering what sort of car do you drive? Do you have your own project or even a preference for a certain engine?

With sodium filled exhaust valves

Bypass??

File this under: "Things that a customer should never be allowed to see" But I like to know how the bacon is made

You look like Vincent Philip D'Onofrio

And you have Space now for coper If you want to

How flow coolant in cylinder head after? It need a separate coolant pump and coolant circuit?

So this is like pouring concrete in your engine to handle the power in a way right? Or am i wrong????

Is that for just for racing the head at tracks

Im sure there is some custom headgasket with no holes for water jackets ?

I understand it's business but why not simply us a head gasket with no water holes in it ?

Isnt there still open water jackets on block side of the head gasket .so water could still get out if head lifts..for that to work ud have to weld the block side 2..think about it. For real

You dont have a smaller rotary tool?

Wait so how do you cool the head?

Who'd have thunk it?

bruh, completely left out the part about the water still being flowed through it, like, HOW? In the first part I swear you said you'll show that later, but like, WHERE?

l wont bring a tig anywhere near a cast head, crazy stuff, simply kills a head, soft as butter now.

🇦🇬 ⭐️⭐️⭐️⭐️⭐️. 🙇🏾‍♂️

Kill the music good video

Why wouldn’t you just do that in a milling machine?

Why weld a hollow cavity. Fill with block fill.

This really didn't need to be a 9+ minute video.

You just ruined that head.

Drag racing is really nothing and lacks progress. This a good example😂
