All 6bs that I have ever saw was nonsleeved friend.If it has liners the engine has probably been rebuilt and fitted with machine shop sleeves.

It can be replaced or it can be only resided if it is not cracked but engine has to be dismantled, it can be replace but on a hydraulic press.

I have checked the part book and there is no sleeves (liners), does cummins sell liners or for this engine.

As far as I know, no. I have got them bored out and a dry sleeve pressed in. Usualy the machine shop/engine rebuilders supply the sleeve and finish it to specs.

I went to cummings dealer today and the guy said that they have sleeves for this engine, he even gave me a part No 3904166

How good is this guys

If they have a sleeve it will still have to be bored out to fit.Machine will still have to do this.

As ddmech says, the machine shop will need to bore the block for the sleeve, and then bore/hone the sleeve to finished size. The Cummins sleeves are way overpriced.
Can you bore block and use oversized pistons?

What is your engine serial number, or original piston number?

Sorry, I cannot find O/S piston part number for this engine, try Cummins, or maybe not available for Dong Feng JV engines.
