Two problems related to engine belts and pulleys have been reported for the 1996 Honda Odyssey. The most recently reported issues are listed below.
Complained about a small oil leak when at dlr for oil change at 90000 mi. Was told that cam shaft seal was leaking. Oil leak had saturated time belt. Dlr recommended replacing timing belt due to possible failure due to oil saturation. Original owner, timing belt had already been replaced at 60000 mi as part of regular maintenance. Replaced camshaft seal, balancer shaft seal, gear set, timing belt, and water pump at cost of $866. Noted other complaints on site of balancer shaft seal problems.
Counter balance shaft seal popped out. Oil was pumped out of engine rapidly. We discovered by finding pool of oil under left front tire. Dealer repair was prompt. Honda paid for seal and new timing belt. I had to pay for cam seal, crankshaft seal, water pump, and coolant. Honda's customer relations at 1-800-999-1009 was unresponsive. Their attitude was "not our fault" . I asked what they would do if engine had blown. Their response was "to probably deny claim since the engine would have to be driven with the engine light on.
