SERVICE INFORMATION

In some cases, oil leakage may reoccur after replacement of the camshaft front oil seal (Figure 1).
To prevent this, always inspect the seal seating area on the camshaft when the seal is being replaced. If any signs of roughness are detected on the indicated area (Figure 1), the camshaft should be replaced along with the seal.
