Technical cam chain problem ?

Jun 9, 2010
I have recently fitted a new chain kit to my 2012 Fiorino 1.3 Multijet, I used the cam and crank locking tools.

The engine is now back together but when I attempt to turn it over with a socket it will only turn a quarter of a turn before I meet resistance, when the locking tools are in place all pistons are half up/half down, is the the correct position ?, I feel that its not timed correctly.

This is the second kit that I have fitted to this type of engine and the first one seemed very straightforward, any suggestions would be appreciated
