Coscost or not?

[djshaggeh]

Got a hold of a redtop for me nova. The guy sold it to me as a redtop with a coscast head. I bought it as it was cheap and ran but didnt check to see if it was or it wasnt.

ks heads are a little weaker, thats all. en the only crack between the coolant and oil channel if you start revving it with a cold engine.

btw, a fixed KS is stronger than a coscast.

As said, it doesn't matter and at the going rate for one, i'm not going to bother!
Even a few coscast heads have gone pourous (sp)

It doesnt REALLY matter, but I have has about 4 XE's and all the KS heads have gone 'porous'...

I am quite annoyed about this (my missus Corsa is now showing signs too) so I would much prefer a coscast, althoughI agree that the prices are a bit silly...

just do the repair and all will be fine...

Anyone ever seen H1 GTE? That has a modified oil gallery on it and has done for a long while without further problems. It has been made into an external line, using some stainless braided hose with banjo fittings at each end.
