alright guys,

just abit of advice, rebuilding motor going forged and all that stuff,

striped the cyl head down today and after abit of cleaning discovered these...


should i worry about these tiny little cracks at all?
there on 3 on the chambers, mostly across from valve to spark plug thread.

cheers

scrap mate, you can test it it will no show up but once its on the car-heat it will fail

 

yeah was thinking that what with expansion and all that. best look out for another one then haha down the scrappy see what i can find monday.

 

probably be better lookin in the for sal section on here

 

if you get a EFI head of another 1.6 CVH swap valve's/springs/cam over good done

 

It isnt scrap at all! It can be repaired or used as is, it's up to you!
99% of RS Turbo heads will be like this according to Ollie from NMS, and 99% of the time they will be perfectly fine to use, if it was fine before you took it off then there is a good chance it will continue to be fine.
Unfortunately the heads are 20+ years old, and so the metal is old, fatigued, and brittle
The head they suppplied me has at least one crack as above and that head cost me £700!!

But... in an ideal world it would be better to have one without any of course!
