Removing
1. Remove the camshaft pulley (see "Crankshaft toothed pulley - removal, installation, replacement").
2. If the key was not removed after removing the pulley, remove it from the seat.
Warning. When performing the following operation, do not scratch the working surface of the camshaft.
3. Prying off the camshaft oil seal with thin curved pliers, remove it from the seat.
Installation
1. We apply clean engine oil to the working edge of the new camshaft oil seal and press it in with a hammer with a plastic striker (or through a piece of pipe of suitable diameter) so that the outer edge of the camshaft oil seal is flush with the edge of its seat.
2. Similarly, we replace the seal of the second camshaft.
3. We install on the car all the removed parts in the reverse order of removal.
