Packard Forum Index » Pre-War (1899-1942)

I have a box of NOS Packard Valve guides, however there are no markings - can someone please advise what the dimension are to identify. I am reasonably certain they are pre-war. Please dip into your pre-war archives and advise.

First objective is to ID a set for Ken Packard for his 115c.

Thank You!

From McQuay-Norris catalog
Exhaust G342 Hole .343 length 3 1/4"
Intake G343 Hole .343 length 3"

35-39-115, 1600,1700,120, 1601, 1701

Confirmed with my removed valve guides. Not sure about the hole dimension, both of mine measure 0.625" OD.

OK, got'em sorted....
I have 80 intake guides, right at 3" long. That should take care of Ken !!
As for the longer (exhaust), I have 15 that are 3.15 long and ONE! that is 3.25 long. Can anyone explain that?

I also have a couple that are longer, like 3.35" - no idea on those...yet, maybe 356?

Also, the machining is not totally consistent on the depth for insertion into the block, pretty much the same, but certainly a couple made on a friday... apparently not a critical dimension? comments?
