I have come accross yet another LS block... *yawn* and am considering keeping it as a pet. This is the problem:
When I look at the cylinders, there is a small amount of material (I guess you could say small chunks) missing from the outer-most edges of the cylinder walls. The chunks are only missing from the top outer edge of the rim. (Picture where a block guard would sit) I have heard this could be caused by some type of corrosion and would not affect the reliability/strength of the block.

Sorry, but I don't have a cam/pics. Does this sound familiar to anyone ? Is it safe to boost this (with a blockguard ?)

 

i wouldnt trust it. send it out and get it built.

 

Sleeve it.

Ahh, sounds overheated to me! heh.

jeremy and I took apart a B18A like that, here are some pics of how it looked... and proper treatment procedures for such a block:

Well, these sleeves didn't look anything close to the pics you posted. None of the 'chunks' even made it half way thru the sleeve and only go about 1/4 inch down or less.

Anything on that ?

 

Some of the damage we caused when we learned the block was toast.

aka the hammer work,etc

 

Holy crap, Dustin...what happened to that block?!

were you grinding off the serial/ vin number off the block in the last photo?

 

I heard they buried it or something?
