We did this like...10 years ago... glad to see the good ole effective ghetto fix is still in play. But I think we bought it from mcmaster, we poured in liquid aluminum though
Back in my tank painting era. We coated the inside of tank batteries with this stuff. I had no idea you could use it for engine heads! Cool deal! Sherwin Williams here has it in 5 gallon buckets lol
Exactly. I spoke with hunter about a product thats been around for years, got his input, did it myself and shared with my following. Gave him credit for the idea 😂 idk why people always have to try to start drama. I have nothing but respect for Hunter Tuned, and woulnt try to “steal” anything.
Question: can you use JB Weld to do the same process, or is JB Weld too weak? The other question is can it be TIG welded to serve the same purpose? I can see how much more rigid the jugs will be with the Devcon added in. Good vid man. Aloha Every Minute. Chief
We did this in 2003 with my buddies dohc zc 86 CRX. His mom came home and we had the entire block in her over, super pissed. The motor lasted for years under a ton of boost.
This is not called sleeving. Sleeving means that you enlarge a cylinder bore and install an insert to cover the entire cylinder wall. Interesting video, though.
I agree. Sleeved many snowmobile engines in my day. Had the cylinder bored over and dropped in a sleeve. I never had an issue with one. On an older Triple cylinder engine, it was a real cost saver. I restored some nice snowmobiles and even motorcycles back in the 90's.
@@Tyler-789 How is doing anything to the outside of the cylinder an alternative to repairing a damaged inside wall? Sleeving is done to salvage an unusable block when wear or damage to the cylinder wall(s) is beyond the point of safe machining.
WOW really what was all done to the engine? i never could do that even on a stock k20a2 . i was using wet kit anything over 150shot k20a2 would go boom. on turbo we made killer power and my tuner stock k20a2 made 700whp for 10 years but spray we had no luck
We use to do this 10 years ago makes me laugh we thought we where innovators back then. We always filled it to the top then when they machined the block it was perfectly flat
Can somebody please tell me what's going on here. He is putting chemical weld or something? around the new liners. What about the underside of the block what blocks the gap between block and liners/sleves
it sounds good but if honda would redesign the block this wouldnt be necessary, have seen engines with this mod with the side of cylinder blown out , good idea bou a temporary fix at best, if ya dont run more than 10 psi of it will hold up pretty well, any more than that and you will have problems. also the epoxy doesnt expand and contract at the same rate as the block, so eventually it will become loose and fail
How tall was the devcon? When once applied onto the block what was height on it, about 2 or 3ins ? There's only so much room it can take since the sugar is there to hold the devcon up from falling and seaping through
Just curious as to why the water jackets weren't flush filled or a touch overfilled seeing the block is getting decked and bored anyway, more material may make it stronger by supporting cylinder walls also it'll have a clamped mating force against it by way of head/gasket.. Then drill water channels after machining is done. Also any idea of the expansion rate of the product as opposed to what the surrounding metals are at temp? Seems like a good budget solution to open deck blocks if it works out.
I think it would be interesting to try, you would have to deck the head and possibly re-bore to account for any warping. You could probably minimize any warping by keeping down the heat
Yup. This method has been used since the early days of drag racing. The trick is to select the right filler that has an expansion rate close to the block material.
SP Tuning.. Your openness to sharing other youtubers channels, like another of my Favorite Mr. Tuned. Makes me know you guys are the ligitest of Papi's.
Devon makes a number of different mixtures. Some have ceramic beads for wear protection. Others are even used to fill heavy wear areas (gouges) in the ways of machine tools. Another use is to fill casting areas of the types of mills and other machine tools that you might find in a home machinist's workshop
An old school trick that's been around for decades. Drag racers used to bore their blocks within an inch of their lives before the days of custom billet blocks. They used Devcon to stiffen up the bores like this.
Devcon makes great products. I ran across many aircraft repairs in my career where Devcon products were specified to be used in interesting and unusual ways when a traditional fix would be cost prohibitive. Good luck with that, if anything will work, Devcon will.
upside downdog you would be surprised how much the northeastern power grid relies on Dev-Con and another name to look for is Belzona.They make an epoxy/aluminum product that can fix a race block.No B/S!!! A real fix,not a band aid!!
Embecco 885 was the super top secret block filler back in the day. Its some space program stuff. I have an old friend who fills his iron blocks with molten aluminum
Ok I get you. I’m a long time small block Chevy guy and I was thinking sleeving like cylinder sleeves that you over bore to install. I thought, “ok I have to see how this works.” Wow good idea. Im not much of an import guy except for stock applications but cheers to you my friend. I can always learn from you guys and I’m definitely willing to. Take care and happy racing.
I hope this works out for you guy like it did hunter mines is doing well also. I did see anyone on youtube, has done it so I was like fuck it i'll be the first. =)
Devcon is defiantly a good upgrade but the bad thing about the b20’s are forsure the sleeves the only problem you’ll end up running into is in between cylinder 3 and 2 that’s the weakest point
It looks to me like a upside down half fill. Theoretically it will work. the only drawback is that the top is the hottest part of the engine. That is why aluminum heads came about . It should be ok for the strip but the street, Id be worried.
Taping off the deck and cylinder surfaces to fill the grooves to the brim and skimming it with a bondo spreader will give you a good compressed fill with a smooth flush surface. Just to avoid coolant seeping where you don’t want it. Don’t pull the tape off until the product is dry enough so you don’t tamper with the perfect surface. Resurfacing the deck will remove any tape that’ll be stuck to the edges. Even a block with smooth sandpaper will clean the edges but you’ll have to know the gasket your going to be using in order to know what the required (surface scratch) on the deck is recommended or else the gasket won’t BITE correctly. The more solid of a gasket material, the smoother the surface.
Nitrous doesn't increase cylinder pressure to push harder on the pistons to make more torque at any specific engine speed therefore increasing horsepower? Wow. Who knew? Nobody with a freaking clue about engines...
Might want to note that Devcon makes tons of different epoxies. This is 10110. Using any other Devcon product will produce different result IF this even works out for them longterm.
I’m trying to do this on my b18. Do I use plastic seal putty or aluminum putty I’m confused cz I’ve seen people do the plastic one and the aluminum? Can someone give me the link please
I'm just curious, but wouldn't it be better to to install and torque down a deck plate(like the ones used during cylinder honing) to keep the cylinders from moving or dis figuring during the curing process of the defcon? I've used Hardblock and always torqued down a deck plate during the curing process.
Devcon on anything other than setting turquoise into a piece of jewelry is just stupid, plastic compounds is not metal in any way and is doomed to fail fail fail fail costing way more than doing it right in the first place. Final round, 2 hrs till lane call, well, maybe. Better to show up, the other lane may fail or red light and then you can drive to the return road. That is the only time to use Devcon.
That's not Sleeving. That's filling in the water jacket for an unknown reason. Sleeving is cutting out the sleeve or cylinder wall and replacing it with "sleeve". What is wrong with you ricers?
Good Night Pablo i know this its a old video but I have a? do its worth it cant u street run like that how long it hold let me know i have a spare b 18b the im planning to go like that but dont know how u handle it after that
Why didn’t you just buy a block guard you could find one for a little more than 40 or a quality one for 100 but definitely way better than doing all this
Ah I never considered this before...seems like a good solution, considering it's not gonna be a crazy power setup. Good job 👍 Might consider this in the future!
If the diameter of the bore exceeds the maximum for overboring for an actual sleeve, the machine shop wouldnt do it. Nothing like blowing out a cylinder wall with the boring machine. Plus the sleeve wouldn't seat. I did a lot of sleeving back in the 90's on snowmobiles. Some motorcycles, usually classics. I miss restoring vintage stuff.
Also here because of boostedbois. I'm not a tuner but this is really interesting. So what you are doing is making a barrier around the top of the combustion chamber to help keep the cylinder sleeve from mushrooming open with the huge amount of combustion pressure? Am I correct?
Another thought is that open deck sleeves move around under big power damaging the head gasket and loosing seal. This is a budget closed deck conversion. I think its pretty cool.
ThriftStore Hacker not so much mushroom (make bigger at the top like a well worn valve tip) as it is deflection (side to side movement of the cylinder). The combustion force in the cylinder is not applied evenly to all of the cylinder wall, as the cylinder doesn't just fire all of the fuel in one neat little hit. It burns across a flame front which means the pressure wave will also vary in the cylinder (super fast) causing a side to side rocking motion like the TheSplendidVids alluded to. Which in turn will try to rock the cylinders (very fast like an orbital sander) and deflect the bore causing a loss of sealing. By trying to hold the top of the cylinders more rigidly it reduces the chance of movement, which makes for a happier head gasket and better ring sealing.
Dodgy Brothers interesting. If you aren't too worried about mushrooming the top of the bore out would it may be more stable to drive vertical pins between the bore and engine block. I feel like the epoxy would be ground into dust after a few hard runs of the engine. Some aluminum or steel rod could be had at the hardware store for $10. Your thoughts?
You do actually get a slight temporary mushrooming / balloon effect in the bore (especially under big boost or lots of nitrous) but it isn't at the very top of the bore like you might think. Remember the fuel doesn't start to "effectively" burn (so no pressure spike) until after the piston is traveling down the stroke (even though the plug fired BTDC). So the mushroom effect takes place more like a quarter of the way down the bore where the walls of the cylinder balloon out leaving the top of the cylinder and half way down the bore in place. Whenever you see a split bore it will generally be in that area. Like you say though I would be skeptical of any material you could hand drill and leaves a power residue (even if it work hardens with use). If he had drilled it and it came out like swarf like you get when drilling metal I would have more confidence in it. My personal choice (because I built one) would be to CNC machine a 16mm aluminium plate that snuggly fit in the top of the bores.
Devcon+b18 block= semi-indestructable. But its always good to do it right the first time, but hey if u already committed into building a stock sleeve nitrous or turbo motor its not bad at all. Id take devcon over a block guard anyday lol and its cheaper too. Good work on the video man! Cant wait for the B20v Nitrous!
dude you an all the other guys made me wanna build up a h22a 92-95 i believe are the yrs the obd1. i hear the obd1 h22 is closed deck an can hold better under pressure then the new open deck am i correct in this?
Like what? A 4g63?... just buy an evo! thats a great idea? Cast iron heavy piece of shit block and then he can replace transmissions and differentials all the time. Or you can spend 2500 on an aluminum 4g63... what a stupid thing to say, lol
That should work just fine. It just needs to keep the cylinders from walking around. I have worked with Devcon aluminum repair putty with some success on aluminum, however it requires you to bake it in an oven. Don't know how much of a difference it would make, but it is made for aluminum. You could also use a pastry bag if you are worried about your ziplock bag exploding all over the place, or maybe even emptying out a caulking tube, and filling it up.
Wanna know if it worked ? Click here :

Just a Tip, lay down masking tape across the head sealing surface then use a razor blade to cut out the water jacket.
The title should be saying the cheapest alternative TO A BLOCK GAURD

should probably get a shop to cnc a part that can fit on the piston sleeves, that stuff is probably going to brake apart and pug the radiator.
What's going to happen when it will go through couple heat/cooling cycles?

Haha thats awesome !
devcon for the price defiantly works used it on some v8 blocks in the past never any honda engines though good idea man.
I wonder about thermal expansion... Any risk of cracking the block?
Good video mate, might have a play around here in Australia, cheers ,

Can somebody please tell me what's going on here. He is putting chemical weld or something? around the new liners. What about the underside of the block what blocks the gap between block and liners/sleves
Yeah, more DIY's brotha💯🏎
why would there not be some cast in support for the cylinders? at least a couple tabs on either side
it sounds good but if honda would redesign the block this wouldnt be necessary, have seen engines with this mod with the side of cylinder blown out , good idea bou a temporary fix at best, if ya dont run more than 10 psi of it will hold up pretty well, any more than that and you will have problems. also the epoxy doesnt expand and contract at the same rate as the block, so eventually it will become loose and fail
how many centimeters are there between the sugar and the devcon
So from bondo Honda body panels to bondo in the engine sleeves lol.
Lol
How to give your engine diabetes and attract ants to your garage.

I see a birthday cake w devcon frosting on it in you’re future👍🏼
Same as a BlockGuard isnt it?
Whats the difference between this and a block guard? I run a block guard on my turbo d16
Nice bro, never thought about doing that. Does Devcon expand?
Not to my knowledge
Could you possibly use a fill weld to bridge the gap so that way you are actually combining the metal. Or would that warp the cylinder?
Not sure tbh.
I think it would be interesting to try, you would have to deck the head and possibly re-bore to account for any warping. You could probably minimize any warping by keeping down the heat
Why not Devcon F for aluminum?
That is one sweet job.
Lovin this build Pablo.
I mean it’s a different idea but why?? You can buy an actual block guard off of eBay for 50 bucks! If you’re trying to do a cheap build
Why not just do a block guard it holds the same area and their cheap
Why didn’t you use a 20$ block guard?
Don't forget to Put the sugar back in moms cabinet
Lol
Its all about the, solution
Good job 👍
That barefoot block build coming soon ....show off them white toes!😹😹
Lol
cool shit dude
Do this on a stock bore b16 or b18 and you have a 600hp capable block😂
Seems like a lot of stuffing around to save $125 on a block guard.

Yea I was thinking this was a new twist on the old “block filled with cement” trick you stated above.
