Ahhh good to know the 2l sump works, and the servo is a bloody good idea! think i will do the only honourable thing i can here........... and copy it if it works well

If your budget is tight there are a good few using the standard zetec bottom end with .5mm skimmed from pistons, (although this was a zvh and i don't know how different the combustion chamber volumes are between a zetec head and cvh).
