Today before I resumed installing rocker arms on the 4,5,6 bank, I installed the distributor.
I rotated the crankshaft to "Z1" for cylinder #1.
Before removing the distributor during engine tear down, I made a paint mark on the outside of the distributor body corresponding to the rotor orientation and another set of marks on the timing adjustment slot where the stud from crankcase goes thru indicating the position of the distributor. Then when I installed the distributor I just lined up the marks and drove in the distributor, the sealing o-ring requires a tap of a hammer to the distributor shaft (with a wood block in between) to set the distributor in place.
Then I installed and torqued down the flywheel using red Loctite on the flywheel bolts.
Finally, I got busy installing the rocker arms for the rest of the 4,5,6 bank and setting the valve lash. Then I installed the valve covers.
Next, I installed the oil cooler. I coated the thick rubber sealing rings with clean motor oil, installed then on the crankcase, then positioned the oil cooler onto its 4 mounting studs and tightened / torqued down the mounting nuts using new spring steel washers.
Once I get the replacement timing chain tensioner and the o-rings for the tensioners, I can close up the timing chain boxes.
