While having some preventative maintenance on our 8V92TA, this rust was discovered in the engine , passenger side. This is the first time the valve cover has been removed in the past 7 years and 38 thousand miles. WE have had several oil analysis done during this time, with zero water or coolant found in the oil. Would a Detroit Diesel repair shop have left this rust , and not removed it during the rebuild process? Am I not bringing the engine up to full operating temperature often enough (every 30 days ) during extended storage? Any thoughts?
