Bypass filtration means that the oil goes through the engine then to the filter, and only a small percentage is filtered. Full flow filtration means that the oil goes from the pickup tube to the filter, then to the pump, then to the engine. You can obviously see why full flow is better.

Have never seen that kind of filter but wonder why more cars didn't use or make it available as option instead of the bypass system most had. Was it also bypass? It appears to come off a fairly high pressure area and must have had some merit if used in chemical industry. Maybe too expensive? Only aftermarket setup I remember having any visibility in 50's was the TP thing which resurfaced again a decade or so later.

Yes, you've triggered my memory and I'm certain you're correct. The name was Cuno, we also used them in the chemical processing industry. Thanks for the memory jog.

Think the thing with a handle attached to oil pump is oil filter remember seeing a Cono or Kumo not sure of spelling used on older cars oil passed thru set of thin steel discs to clean oil you turned the T handles which turned plates which were wiped by similar set inside the housing this type of filter was used on oil systems on late 30 early 40 cars remember seeing picture of same in old motors manual that my fatheer had also he had one of those filters on a Studebaker he had after WW2 can't remember the spelling but do remember helping take filter apart and cleaningn Normal cleaning only required a few turns of the T handle on top of filter. Will look for manual and pictures later

The difference in length might be due to the Russian's use of the Metric system maybe? I'm not sure if they used the Metric system, but it's a thought.

Good point about silver soldering it in place given the temperatures needed for silver solder. Perhaps an alternative would be to turn a small brass or copper plug of the correct OD and sweat-solder in place using regular soft solder.

Randy, Glad I could help. Although not an exact replacement, I found that my local Ace Hardware had rubber fender washers. They were about 1.75" in diameter but easily sealed the cowl hole with the flat washer.

I have not removed my antennas but took a couple pics for you this afternoon. It looks like there is rubber protruding from both the outside and inside from the original grommet. Hope this helps.

Regards,
Robert.

I find it interesting how round that hole appears to be--like it was placed there. Can't see that much detail but surely it would be more jagged or you'd have noticed if you had done it accidentally with the phillips.

Went back and checked but there appears to be only one end piece for both years so should be the same. Hydraulic charts also show no escape or bleed path through there. Can't imagine why it would be done on purpose though because it opens a fluid path that would have surely caused some major disruption & shift issues in transmission.

At any rate, agree with Owen about the solder--just not sure how you'd do it without removing the retainer again to thoroughly clean and solder outside the diecast. Since the melting points are so close, wouldn't even think of attempting in place.

I went to the Greenwich (CT) Concours d'Elegance yesterday and saw something that really piqued my curiousity. The car in question was a just lovely 1933 Twelve convertible roadster (1005-639) and the thing that got my curiousity was the use of green cloisonne' on the hubcaps. Now I know that plain cloisonne' (without the "Packard Twelve" lettering) was available though I don't know if it's listed in the parts or accessories listings but I never have read or heard anything about different cloisonne' colors being available, yet the owner seemed insistent that it was bona-fide. Anyone have any supporting data or observations?

BTW, while not quite in the class of Pebble, Amelia Island or Meadowbrook, Greenwich is a terrific event and if you're within driving distance and don't go, you're really missing something.

I didn't look at Steels piece but isn't there quite a different setup for rear antennas on regular cars vs the Caribbean with the chrome piece. Maybe that is the seal you refer to.
