 Though the Zephyr V-12 no more resembled previous Lincoln engines than the ubiquitous V-8 (despite sharing the latter's stroke), it was more like a "12-cylinder Ford" than a classic multi-cylinder powerplant in character.And it was not without problems.The main ones were inadequate crankcase ventilation that caused rapid sludge buildup in sustained low-rpm running, aggravated by poor oil flow, plus too-small water passages that led to overheating, bore warpage, and ring wear.
