b18c block question with pic- do you think this is safe?
i bought this block of a guy that had these beads installed into the block pictured.... he claimed that its good for high rpm, but im worried that it might cause trouble... what do all you people think....

anyone?

Beads? What the? Or are they Posts? Not that I claim to know a lot about engine building, but I think that is bad news. Just imagine the engine warming up. The sleave expands with heat but those Posts are holding it in place at cirtain spots and may warp the sleaves so to speak. Its just comon sense to me that it is trouble.

Nothing, its an open deck.

so its a bad move.... i should get them removed?

doesn't water flow through there to cool the cylinders?, this would restrict the flow which is bad for overheating?? I was thinking that they may have been a form of a sleave guard. True the block would heat up and expand causing these to push against the cylinder walls and could warp them. Not too sure but very interesting

I am not one to say, probably best to speak to somone with more experience in engine building. Posting is "supposed to" strengthen the cylinders, but I have heard and read they cause more harm then good. It will restrict water flow and may cause warping. The cylinders in stock form are pretty dam strong, especially for NA applications.

umm it doesnt look like ur average block gaurd.. hmmm no idea. its bad if it was done wrong!

looks like he was trying to 'sleev' it.

That block looks posted. Have a look at the side of the block and you should see filled up wholes where the 'pegs' were put through. Hopefully they used the same material as the actual block itself so it will expand at the same rate.
