Reviving an engine that has sat for 2 years
The factory 304 V8 in my 74 CJ6 ran when I parked it for a frame off teardown. It has been in the chassis and wrapped in a tarp to keep the elements out. I am sure some moisture and salt air have found its way in through the exhaust and carb. I was told that I should remove the plugs and squirt marvel mystery oil or another heavy penetrating oil in the cylinders and let it sit for a day before turning it over. Is that the best way or can I do something better? The block had a freeze plug pulled before storage so it has nothing but oil in it.
