Hoping someone can help me identify what type of sleeves this block has- I picked it up on CL and could use a hand identifying.

SORRY for the terrible pictures- camera was at my house borrowed a buddies that cannot take macro shots.

The block has an inlinePRO block guard, and what looks like a different material inner sleeve. the outside water jacket side sleeve is sunk down slightly versus the inner bore sleeve.
















Thanks!

 

Doesn't look like a sleeve or CSS at all. looks like a block guard.

It Looks like a block guard. And u may not need to sleeve it anyway because gsr can hold a good bit of power.

 

Stock sleeves with block guard.

 

Why does it look like the inner sleeve is sunk compared to the water jacket?

 

They definitely are different than stock, as I have a stock GSR block sitting right next to it. I will get you guys some quality pictures ASAP for better identification.

 

Looks like dry sleeves to me.

 

That is unneeded. That is just a decked block with a block guard. The metal may be sticking up slightly because the aluminum has "shrunk". Typically there is a reason why somebody is getting rid of what they are selling. If you look at the cylinder liners (steel) they are uneven thicknesses all the way around on every single cylinder. IF they were aftermarket Dry Sleeves, they would be even. That is a factory setup bud (aside from the pointless block guard that is).

 

The innerpiece of material is consistently .090" lower than the outside sleeve. I highly doubt that the inner material "shrunk" .090" all the way around every bore- think about what you said and ask if that makes sense.

Here are some better pictures-











Now could there be a chance someone went through and milled the inner sleeve down on each bore? Why on earth would they do that? I honestly am pretty confident something has happened with this block involving the sleeves-

 

You don't have much head gasket sealing surface between cylinders.

 

OP - If YOU actually read what YOU posted in the very first post you would see why I came to the assumption I did. You said the outside was lower than the iron sleeve... The original pictures were horrid and everything looked factory. Seeing the new pictures they could very well be improperly installed Darton 200 sleeves or the likes. That block was ran for a short time as it sits from the looks of the tops of the SLEEVES (cylinder walls). In its current condition that block is unusable. A .090" milling would be unacceptable.

I would just start from scratch with some stand alone replacement sleeves like some Darton Mids. There are a handful of manufactures that make sleeves that will completely replace the sleeves and aluminum support structure.

 

Hope I can be of service, what you have isn't a sleeved block, its stock sleeves with new liners. These liners tend to have problems sinking. Now brand wise, I can never tell with liners.

Not sleeved, its an insert put that that thing away for some real sleeves (RS, GE, Bensons), nothing but sealing issues to come. there used to be a place in LA that used to insert half sleeves as they call them nothing but complaints and over heating motors pushing combustion in the coolant system
