It is not intended to be diassembled beyond the point you picture except the mesh portion should lift out of the lower oil pan. The majority of the dirt removed will be in the bottom of the pan. I don't use gasoline to clean mine, it can damage the paint and of course there is the flammability risk. I use either kerosene or charcoal lighter fluid which is much cleaner and more-or-less odorless. In either case I don't use gallons of it and soak it, rather I hold it over a waste oil container and thoroughly spray with the kerosene or lighter fluid until the rinsings come clean. This is not only neater but you also use A LOT less cleaning solvent. I don't live in dusty areas so I clean mine about every 8,000 to 10,000 miles so maybe once every 8 or 10 years. Despite an occasional chore to clean them, the oil bath filter (optional on your car) is more effective than paper elements and I encourage you to retain it.
Re-oil with SAE 50 non-detergent if you can find it, my local NAPA always has a limited amount on hand. Illustration from the Serviceman's Training Book "Know the 24th series Packard".

Thanks for the reply Owen. The problem I am having is with the mesh element. I cant seem to get it to separate from the pan. I have tried turning it, prying on it, yelling at it lol. I can't seem to get it out. Is there something I'm missing?

Not that I'm aware of. Continue applying gentle persuasion.

There is a rubber seal that may be stuck.
I know this topic has come up before, but the Packard manual only mentions cleaning the element as regards the non-oil bath unit. Some marques specifically advised against using solvents on the element unless the unit was blocked by dirt. So I would just clean and refill the reservoir. Anyhow, the way thing works is the oil is sucked up and released which cleanses the element. Thus, using a detergent oil should be beneficial. However, 50 weight detergent oil is rather hard to come by. Using a lighter grade will require in more frequent checking and refilling of the reservoir.

Ok. I guess I'll just have to be a little more agressive trying to get the sucker apart. Thanks guys!

I use odorless thinner for cleaning my oiled air cleaners. Flammability is low and the lack of smell is a big plus with me.

I just swish the filter around in a pan of Varsol or paint thinner (similar but cheaper) then let it drip dry. Do not blow air thru, you can make channels that will let unfiltered air into your motor.
You can drain off the oil from the oil bath, wipe clean with old rags or cotton waste. Refill to the line with 50 weight oil. You can use 30 in below freezing conditions but, it is important not to use thin oil, it can splash around and get sucked into the engine. As long as the reservoir is no more than half full of dirt it is ok to top up the oil and let it be. They recommended servicing at oil change time but if you drive on paved roads and don't live in the desert they will go for years. Just check at oil change and tuneup time.

The filter element normally just lifts out of the lower part that holds the oil.
Here are some photos of the assembled unit and the individual parts.

Some sources claim that solvents degrade the element which reduces the efficiency.
