There is a small possibility that the timing belt may have been

and replace it if it has been contaminated. See Figure 1.

2) Remove the No. 1 intake and exhaust camshaft holders and remove camshaft oil seals. See Figure 2.

3) Clean the camshaft holders and camshaft oil seal seats on the cylinder head.
