How about some details on exactly how you did the compression test. For example, were all 8 plugs removed, were both the throttle and choke valves held wide open, did you repeat the test after adding a small amount of oil to each cylinder, did you run at least 3 compression cycles before recording the final compression value?

For an engine that has sat for many years, the compression may (or may not) improve with more running time, so don't jump too quickly to disassembly. The comparison between dry and after adding oil will help indicate if the compression loses are due to rings or valves.

momo, I would suggest finding and joining a local old car club to help get you started. There are so many little things to over look, that someone that knows old cars can just look and listen and tell you what and how to do it.
On a side note if they suggest doing an engine swap, I would find someone else due to the Packard engine is an excellent engine.
A plus is good friendship with people of like interest.
Wes

good afternoon sir yes i took compression with 8 plugs removed by the way all 8 are black but not wet i opened the choke and hold the throttle open took the compression with 5 cycles even 9 cycles on some but it reads 25psi on 2 cyl. after that i put about 3 teaspoon of o?l with a vacuum hose inserted in plug hole to get access to the piston i got 35 psi. on other cylinders i have 30-35-35-45-45-45 with o?l i mean the add of o?l increased compression by 10 psi i know my gauge is accurate i removed the side covers i wanted to check if the lifters were moving freely they are in this area everything is clean and oily when i crank the engine it turns like free and i feel that i could start it by hand with a crank sorry for my English i am a french quebecois regards Maurice

Maurice, the fact that your compression did not increase dramatically with oil added suggests to me that your loss in compression is primarily thru the valves.

OD is of course correct, but with the general condition of
the car, if it were mine, (I wish it was) I would give it some time, sticking valves could be causing this problem,
it should improve by running at a reasonably high RPM for
a few minutes then idle a while then repeat,you should know if it's helping if your idle starts smoothing out.

"i removed the side covers i wanted to check if the lifters were moving freely they are in this area everything is clean and oily when i crank the engine it turns like free "


Thinking that if it runs for an hour, even with the very low compression, and you've checked that the lifters are working then the valves aren't stuck. Although it may be advisable to specifically check to see if the valves stick while running rather than just by turning the engine over. If they aren't sticking, would probably point to the valves and valve seats needing grinding/resurfacing and lapping.
