Bought a 1950 Packard barn find, just got it running and the blue smoke is pretty bad when shifting. Rings? Also when shifting it grinds into gear. Clutch? Any help is greatly appreciated. 288 straight 8 with 3 on the tree with od.

G'day streetrodder49,
to PackardInfo and for including your '50 Deluxe Eight Club Sedan in the Packard Owner's Registry. And what's that in the shed, a Caddy?

Will leave it to the more mechanically knowledgeable to comment on your questions.

Hey, Street (cool nickname for Streetrodder49),

As a barn find, did you do all the precautionary and preparatory things before driving?

Here's an article on the causes of blue and other smoke. Excess oil is one cause. What's your level.

https://www.cjponyparts.com/resources/exhaust-smoke-color

QUESTION Is the tranny and overdrive full? Low gear oil causes grinding.
Also not following the H when shifting, like cutting across diagonally from 1st to 2nd, can lock up the linkage.

With OD sitting a long time, you can get grinding at startup. Pull out the overdrive knob, be sure you can shift into Reverse before you start it, then put it in neutral and start it.

Someone here may have better ideas and ask better questions like "Shifting grinds between which gears?" But you're off.

At high miles engines of that era will smoke like a loaded freight train. High meaning anything over 80K depending on how it was used and cared for. A set of rings will do wonders and can be done on that engine in long afternoon. Run it a while and see if it doesn't get a bit better as things limber up. Could also try blocking the pipe from the vacuum section of the fuel pump to manifold. A breached diaphragm will let a lot of oil into the intake.

If it grinds going into gear at a stop it is the clutch. If it grinds while shifting it is the synchronizers in the trans. Change the trans oil and be sure to use a GL-1 rated 90 weight oil. GL-4 oils that are right for the rear axle have too many friction modifiers and the synchros can't grab properly.
