OST-032: Skippy gets a head
Some of you know I've purchased a daily-able FX16 so I don't have to use Surreptitious(AE71) all the time...

I named the FX "Skippy", and knew upon purchase that it didn't run.



This is what was found when the head was pulled... something broke, and eventually got embedded - see arrow

So.... OST-032 is Skippy's new head!

stripped and ready for cleaning........

Can anyone tell me why one chamber is already clean????



More to come..... Hurray!

normally these would be a great guesses....



But in reality this was a VERY loaded question - apologies Wink This chamber was the chamber used to make the chamber casting....

can't win sometimes.... nature of carnival games Wink



So Skippy's head is back from cleaning and pressure checking. The chamber depths and the seat depth all look VERY good. There is some excess material that was left behind after the head was machined @ Toyota, that will all get cleaned up :thumbsup:

It measures just about what an uncut head is suppose to measure - easily within the .001" tolerance of this caliper

Work begins on chamber/bowls of #4 cylinder

Now that the casting has been massaged... It'll go off to the shop on Monday to get its 3 angle, and have the head surfaced.

More to come.... Hurray!
