RE: OST-050 - a VERY special build
Well... some good news, and some not so good news......

The not so good news first... The soda blasting was nearly a total waste of time, money, and energy. The manifold, t/b, and TVIS plates will all need to be glass beaded. Crying

Glass beading means that the T/B, and the TVIS plates need to be completely disassembled prior to blasting to avoid the glass beads remaining and damaging the rotaional surfaces of these pieces. The AAV can not be fully disassembled, so I've been working with aluminum jelly to get the surface as "bright" as I can. Once the T/B come back, I'll see how close the two are to each other and "adjust" as needed.


I've recently found out that Toyota did not paint their blocks, but had them dipped into a black phosphate solution. This information comes from 2 highly reliable sources - one worked for TRD back in the early 1990s, the other is VERY well known to the Toyota, and 4AGE community.

So I spent a few days calling machine shops in and around the greater Portland area, and found no one doing phosphate dipping of engine blocks. There were a few smaller shops that did offer a black phosphate dip for hardware, but they couldn't physically dip, or coat the block. So with a phosphate dip out of the question, I found another solution...... Love it!

This isn't flat paint, nor is it semi flat paint, in fact this isn't paint at all, it is far thinner then paint (.25-1.5 mils thick, vs 1.0-3.5 for most spray paints)


The only downside to this coating is its total curing time of 3 weeks!! Angry



more to come....... Hurray!
