Note: Given that special tools are required to remove and inspect the head, it is recommended that you purchase a new or reconditioned component from an engine rebuilder. This may ultimately be cheaper than rebuilding the head yourself.
Warning! On F7R engines, the exhaust valves contain sodium to improve heat transfer. These valves CANNOT BE DISPOSED with their contents. It is better to cut them in half and soak them in water (4 valves will require 10 liters). Observe the necessary safety precautions.
Petrol engines
1. Remove the rocker shaft (1.4 and 1.6 l engines), camshafts and tappets.
Diesel engines
1. Remove the brake vacuum pump (refer to Chapter Brake system), fuel injectors and fuel pump if removed with the cylinder head and camshaft and tappets.
All engines
