Vapor Blasting

Post by 528i-1981 » Sun Jul 07, 2019 7:47 pm

Gents: Brought a replacement valve cover (hat tip PatinaBeforePolish) and six 320is valve runners to New England Blastworx in Hinsdale NH for vapor blasting.

10 micron glass beads and water at high pressure. The result is a creamy smooth surface with the pores in the metal peened closed so that they can be wiped clean. Still waiting for the frame welding to be done before I can mount these ...

Looks amazing Eric. I am looking for two more 320i intakes to have enough to do that modification as well. What did the glass beading cost?

All six tubes plus the VC for $150.

Yes, I can't find any flaws except one small stain where oil had leaked through one of the intake runners from the inside. These parts look better than new. Turnaround was under a week.

Agreed that looks great, I was thinking about painting some of my old parts but getting them as clean as that is a better result.
