Hello,


First sorry for my bad english :D

I am from Europ and last year buy Packard 1936 - 120 in USA.

Can you help me with engine repair? Is it possible to get some manual instructions for this model?
We try to nurture the engine but dont know details how to make it work properly.

Pleas info if someone sell spare parts for Packard (in general) or is the best finde special part whene is needed? Ask for the future.

Send picture from car and info about model.

Welcome! Looks like a lovely Packard.

All the various manuals are available as reprints, you should consider buying the owner's manual, shop manual, and parts list. These are all offered for sale in the Shopping Cart section back on the main front web page. And while I wouldn't say parts are plentiful, you should be able to find all the important parts to keep your Packard running well. The two large national Packard parts suppliers are a good place to start, Max Merrit and Kanter Auto Products (whose advertisement and phone# appears at the top of this page).

When your questions and parts needs are more specific, we'll be here to help.

Based on the stampings of the information, your patent plate (vehicle number plate) appears to be an original. But if you are interested in authenticity and correctness, it should be attached with regular slotted head screws, not Philips head screws.

- adjusting the valve
- adjusting the ignition angle

This should help until you get your books.

Valve clearances are set with the engine hot (normal running temperature) and preferably running at idle.
Intake clearance, 0.007 inch
Exhaust clearance, 0.009 inch but revised the following year to 0.010 inch.

Dwell angle as a specification was not used as early as 1936. You set the points to a 0.020 inch gap which should correspond roughly to a dwell angle of about 33 degrees.

Firing order is 1 6 2 5 8 3 7 4

Compression depends of compression ratio and altitude, see chart. Most important is that the values fall within 5% or at most for a worn engine about 10% of each other.
Compression versus altitide.jpg
Normal compression ratio for your car was probably 6.5/1.
