Oil leaking from several locations

03 honda accord 224k miles. was adding a quart a month, now, after taking to a disreputable shop, is leaking from several places, according to another shop. 2 questions, how clean up to verify where its leaking and how much? and what should I do about it if true? I have to hang onto this car.

To clean up, place a catch pan below the engine and spray the engine down with brake parts cleaner.

Has anyone checked if the PCV system is restricted?

After cleaning engine as best you can, there is a dye at parts stores you can add to your oil. Drive it and in a day or two take a black light and follow the trail of oil to its source.

thanks v much
