I liked the video that showed guys driving sleves into a block without cooling. They only broke a couple of the sleves. Placing the sleeves into a insulated box and chilling with a CO2 fire extinguisher also works.
Why install dry sleeve instead of just boring and honing for a new piston. If you have to hone the block anyway after installing the sleeves. Is installing sleeves needed when the bore is damaged and cannot be honed out?
so you slightly shrink the sleeve and slightly expand the block to more easily insert the sleeve, and to have it better locked it in place when they are the same temperature later during operation?
The video does not explain what the process is here. I have used dry ice many times but I immerse the parts, i.e. sleeve, in acetone that I place the dry ice in. This does two things mostly. One is it prevents ice crystals from forming because the dry iced acetone "coating"won't boil off in ambient temps and prevents moisture to accumulate on any surface while still wet with acetone. It will of course boil off (evaporate) in a short time. And two is there is no need to heat the mating parts making it even easier to install the frozen coated part. Sealer will not be washed off due to the boil off rate. Of course if parts are not properly tolerance'd before hand it will fail no matter what method is used.
Standard -18c freezer and heat gun will work just perfect. Did 100's this way... Keep the cost down, no need for gimmicks. Don't try to change what works perfect
They took the plate off to deck the block. Common practice is deck, bore chamfer and then hone. Decking and chamfer aint gonna happen with a plate on. After machining it goes to honing and the plate goes back on. Seeing as they did not show the honing steps you guys are only assuming they did not use one which is weird 'cause they clearly have the plate.
We need more videos like this.
Great Job.
No he doint

That is the theory of it.

I use dry ice and e85 brings the temp down to about -70 degree. Cheaper than acetone
Hi. There's any video showing this method?

Don't try to change what works perfect
Does that mean we should keep the block at 250°for 30 minutes ??is it same for a small single cyl al alloy block
Hi do they do a liner for a Porsche 997 ? are they alloy sleeves ? Kindest regards dave
Can we put finish honed sleeve the same way..and just deck the sleeve after that..will that do??
@@debbiekonkin5768 thanks for reply
It is Benson's shop ?
You need to be using a deck plate when home the block.
Why does it never work this easy with me 😂
Why take the torque plate off and then bore/hone it?
idiots.
Cronus577 exactly

Nitrogen ? Dry ice ? Why hammer ? 🤷🏼♂️
