Sandblasting an engine

[rmchrgr]

Read an ad for an engine for sale where someone said "Sandblasting exposed some pitting in the cylinders"

Is sandblasting the bores a common practice? This seems to go against the idea that you don't want abrasion in the bores, other than the cross-hatch pattern of a cylinder hone. I can see doing the outside of a particularly dirty block, but the bores?

Anyone have any experience with this method of cleaning?

thats Krazy. Fiberglass bead blasting maybe but not sand.

My thoughts exactly.

hi, don't sand blast a block, take it to a shop, that has a steelbrator. this will clean it of rust and carbon, make block look like new.sand is very hard to get out of castings. it will stay in it, cause you grief. a steel brator uses steel shot,

Sand + motor = bad!!! I had a bone stock 360 hot tanked and worked over and when I got the block home and started to clean it a bunch of casting sand came out of the freezplug holes. My dad had a 350 chevy that did the same thing.

I'm not doing it myself, just pointing out how someone stated in an ad that they had done it already.
