Question Unsticking a Stuck Lifter?

I am a newbie.

According to some older more experienced friends that know about old cars, the noise coming from my engine is a stuck lifter.

I have a 54 packard clipper, the engine in an inline 8.

How do I go about unsticking my lifter? Is there something I can throw in the engine (solvent) or do I need to take it apart to fix. DO I need to take the engine out of the car to get at the problem?

Any sugestions/help would be appreciated

Try (but NOT at the same time), Automatic trans fluid, 1 qt. Or Marvel mystery Oil, 1 pint. If using multi wt oil, change to 30wt after a few miles of the treatment. You want to get the added oil pressure of a cool heavy weight oil to force the lifter piston to move (pump up).

JOgo, I'm not real familiar with flatheads, but if I'm not mistaken, there should be a cover on the side of the block for accessing the valve train.
If you can get in there you should be able to squirt some penetrating oil into and around the lifters. Then let it sit for a while. Then disconnect the coil wire and crank the engine. Repeat a couple times, it might free up without disassembly.
But you need to get a book on your engine and go from there.
The best penetrating oil I've found is called Kroil. Comes in an orange colored can. And after you squirt penetrating oil all over it you'll want to change your oil.

I agree with Ted655 Marvel Mystery Oil, I use this oil in all my motors, keeps everything clean and works as a upper end lub. Add to gas to help 4oz to 10gal. gas.
Luv the smell of NITRO in the morning.
