To flush or not to flush

Hey all.

Purchased a 1986 Wagoneer with the original 360. She has been sitting for 5 years. Still runs (burns a little rich) and is in need of a full tune-up.

With it sitting for so long, the oil, I can only imagine, is more the consistency of old chewing gum than motor oil. I have been considering doing an engine flush to clean out whatever I can. I want to avoid a rebuild at this time (the engine has 215K miles on it). I have read pros and cons of engine flushes.

Any thoughts, opinions, and/or experience in revitalizing an old motor without doing a complete rebuild?

We have a 79 CJ-7 with an AMC 304 engine. She was rough when we got her and we flushed her with sea foam. Works wonders. If you google sea foam engine flush you’ll see lots of examples and instructions. Good luck!
