The 1949/1959 MPC FINAL ISSUE shows a slinger used on the 1956/ Y (B6A 6310-B). Most likely the earlier slinger was dropped from cataloging at some point. I cannot see how you could get away without it, especially on the earlier oil return on the timing chain area.
The FE did have a slinger.
Mark, your illustrations. Can you ID them for me by sequence? Also, one has an ILL NO. Do the others?
The SM was updated quarterly, so there may be variances there.
