"Re-eking" is not a commonly used term in English language and therefore does not have many synonyms. However, if we break down the word "re-eking," we can see it has two parts - 're' meaning to do something again, and 'eking' meaning to emit an unpleasnt odour. So we could use synonyms like "emit an odor again," "stink again," "smell again," or "scent again." It is important to note, that context is key when choosing synonyms as they may not always fit the situation if not used correctly.
