Got the Al parts back from bead blasting....

scott, when you bead blast (which i assume is the same as sand blasting, did you cover the holes on the intake manifold, or just blow them out with compressed air when you finished, also just out of curosity, how much dose a bare m30 block weigh?

sand blasting material is silica particles with sharp edges and it is used for harder metals. it can actually remove material, especially on softer metals

glass beads in bead blasting are round pieces of glass that hit the material and shatter. This destroys less of the material and helps clean the surface.

Yes...I used forced air for a long time on the intake manifold, valve cover (with plate on the inside removed), and oil pan for a long time to make sure no blasting material was leftover

I will weigh the block when I get it back

Damn those are some clean engine parts. Even better looking than when they were straight out of the factory! Can't wait to see it all put back together.

Everything looks GREAT.

Very inspirational. After seeing your pics, I went out to the garage and wiped off my oil filler cap

Buit seriously, with my engine removed, I'm doing a mini clean up. I may even clean, treat and paint the 'new' block I'm dropping in.

Thanks for the pics,

just used this kitchen steel wool sponge, which one uses for cleaning frying pans etc.
But the problem is, that probably over the time the light color will change to darker one and all dirt can penetrate. Therefore I want to give it a protection coat. No color.

On my Highline I have the intakes out as I do a lot of other things on the engine room. So that is much easier to do something.
But if engine is in, just try a bit the kitchen steel sponge. You will be surprised.
