Balance Shaft Seal Caution For
1990-99 Honda 1.5, 1.6, 2.2 & 2.3L Engines
The AERA Technical Company offers the following information on a balance shaft seal caution for 1990-99 Honda 1.5, 1.6, 2.2 & 2.3L engines. This caution is expressed as the oil seal used for the front of the balance shaft may become dislodged, creating engine oil loss. In severe situations, engine damage has resulted before a leak was noticed.
Apparently, the seal retention is questionable on these engines and the seal may move within its housing at an undetermined time. To resolve this situation, Honda suggests installing a retaining clip within the seal housing to prevent the seal from moving. The repair involves removing the front timing belt cover and installing the clip. As the result of these seals moving Honda published a service bulletin describing the use of a new seal installer, Part #TN 07XAF-PT00100. This installer positions the seal deeper within the timing cover to allow room for the clip.
AERA is aware of another source for components regarding a similar repair of this condition, it involves bolting on a retaining plate as shown below.
