Re: 1947 356 Oil Tappet Regulator

Both of my assumptions were false:
1. tappet oil regulator only used on 46 and 47 356's
2. only 1 part number

From SC Vol 20 No. 1, I read the following with respect to the tappet oil regulator piston on the 18, 19, 20 21 series:

Part No. 324579 18th and 19th Super 8s
Part No. 351780 20th and 21st Super 8s
"These parts are not interchangeable"

So I think the mystery is that 18/19 series regulator pistons are now installed in my block. These were replaced in the 20 and 21st series because they didn't work well.

Oh well. This packard documentation is so helpful. Thank you for pointing me in that direction.
