First sorry for my bad english

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.
