Cylinder Head and rocker assembly rebuild
lay in the cylinder head bolts.jpg
Lay the cylinder head bolts in position and twist them in by hand to ensure there is no cross threading. It is recommended that you replace cylinder head bolts. There are 2 sizes for the L3E engine and I bought a couple of each as spares. They have to be torqued up gradually in a specific order which is in the workshop manual. PM me if you need this information.
NEVER EVER over tighten these bolts as they become tighter as the engine is heated up to operating temperature and could easily break
I used my old bolts because Ebenezer Scrooge is a close family member........
Re-insert cleaned glow plugs.jpg
The glow plugs could be replaced at this stage but mine were working fine on the bench test so I just cleaned them up and reused them.
re-insert the pushrods in the same sleeve they came from originally.jpg
Reinsert the pushrods in the same sleeve as they came from. Check them at each end for burring and roll them on a flat surface to test for straightness - as if you were testing out drum sticks .......[what??]
reinstall the rocker arm.jpg
Lay the rocker arm assembly in position and ensure the pushrods are snugly fitted underneath the rockers.
insert the 3 rocker arm bolts.jpg
There are 2 bolts on either end of the rocker assembly that have extended studs to receive the rocker cover bolts [next photo]. The middle one is a regular bolt.
torque up the rocker arm bolts.jpg
Torque up the rocker assembly bolts to spec.
refit rocker cover.jpg
Refit or replace the rocker cover gasket. This is your chance to paint it fluorescent green.....
rocker cover fixing nuts.jpg
There are two nuts for the rocker cover.
Job's a memory.
