From 9/28/20
I did get the rocker shaft assembly and inside of the block cleaned up awhile back...
That was tedious and time consuming but I got it done! Each rocker arm has two oil weep passages. One long one to the outlet above the valve stem and one up top to a tough that feeds the oil to the top of the solid push rods. They were all plugged completely up. Guitar strings and a drill helped a lot but it was still slow going.
I cleaned all the baked on oil from the timing chain area.
Cleaned up the head and lifter valley area...
Before...
After...
I started scraping the gasket off the oil pump last night but couldn't find my parts brush(until a few minutes ago) to give it a good through cleaning. OK, I pull out the distributor and start looking at it closely. Besides being filthy, do you notice anything out of the ordinary?
There are three O rings, two large ones(stacked) that ride on the shaft and one small one(just above the other two) that fits in a groove. The Service manual calls for one...
I think the manual is wrong. There's a bevel in the block that appears to be for the large O ring to sit in. You can see how the bevel shaped the lower O ring in the photo. The small one seals the opening the distributor shaft slides into. The extra large O ring shouldn't be there...
There's some vertical slop in the distributor shaft...
I'm thinking someone added that second O ring to counter the slop in the shaft. To be continued...
