I have a Nissan Safari 1985 model with a SD33 Turbo Diesel Engine. Serial No. 021386T
The service manual states that the minimum of the cylinder is 89.7mm i.e. the maximum it can be ground to.
What i need to know is what is the hight of the cylinder head when new.
(i.e. what is the max amount of material that can be ground off the lower surface of the cylinder head)

Thanks

Colin Davies
