I built a 1.4 16v ftp engine In...
Mk1 electronics and all engine parts
We had to make the mk1 intake fit
The camhouse also mk1 with catcams 264
And the ftp hydrolic cam Followers
And now he spits some oil out of the Carter ventilation
What could be wrong?

Did you check compression levels? Also, is that the one with the oil cooler hooked up to the oil pump housing? (Guess not)

Prolly has to do with those awesome piston rings they used, ring gaps not allingned correctly, it's funny tho, I tought u were the expert on CCH and here you are ?
