OST-050 - a VERY special build

[oldeskewltoy]

Been a while....

part of this build is a complete restoration of the engine back to the condition(appearance) it was 32 years ago. And in that vain I've notice that the block[s] I've worked never looked like they carried paint originally.... and apparently they DIDN'T!

From 2 very reliable sources I've found out that Toyota didn't paint their engine blocks back then, but had the blocks phosphate dipped, that is how Toyota treated the blocks. So in that vain, this block is getting a very similar treatment, the coating on this block will mimic the original, but be a bit harder, longer lasting.

Along with the blocks restoration, the head, including the entire intake, right down to the T/B, has been sent out to be soda-blasted. Once the head is back I'll begin the port work.

before....


Soda blasting is similar to other surface cleaning(sand blasting, bead blasting) but is completely harmless and water soluble - cleans up with water. I'll have an after pic in about a week.


I did clean and test the AAV (warm-up valve under T/B)... it appears to work...



with the block prepped for a new coating, and the head and intake off getting soda blasted... the internals wait on a familiar shop cart...




More to come....
