To replace the crankshaft front oil seal, first remove the crankshaft pulley and, for models from 2001 to 2006, take off the timing belts and crankshaft sprocket. Take note of the seal's installation depth and orientation, then carefully pry it out using a seal puller or a large screwdriver, ensuring not to damage the crankshaft or distort the cover; wrapping electrician's tape around the screwdriver tip can help prevent damage. Apply clean engine oil or multi-purpose grease to the outer edge of the new seal and install it with the lip facing inward, using a seal driver or a large socket and hammer to ensure it is squarely positioned at the correct depth. Lubricate the pulley hub with clean engine oil and reinstall the crankshaft pulley, tightening the retaining bolt to the specified torque. The installation process is the reverse of removal. For camshaft oil seals on models from 2001 to 2006, remove the timing belt and camshaft sprockets, then note the installation depth of the seals before prying them out with a tape-wrapped screwdriver, taking care not to scratch the bore or camshaft. Clean the bores and coat the outer edge of the new seals with oil or grease, applying grease to the lips as well. Use a seal driver or a socket slightly smaller than the seal's outer edge to carefully drive the new seals into place, ensuring they are squarely installed to the same depth as the originals. Reinstall all removed components, ensuring correct alignment of the belt and sprockets, and clean the areas around the seals to detect any future leaks. After operating the vehicle for a few days, check for leaks.

Lubricate the outside diameter of the seal and install it over the end of the crankshaft, ensuring the lip of the seal points toward the engine.

The first step is to remove the timing belt and crankshaft sprocket.

Reinstall the rear timing belt cover and tighten the bolts, then reinstall the camshaft sprocket(s) and timing belt, verifying that all timing marks are aligned to prevent major engine damage. Finally, run the engine and check for oil leaks at the camshaft seal.

Clean the seal bore in the block thoroughly with a shop towel, ensuring all traces of oil and dirt are removed.

Install the retaining bolt and tighten it to the specified torque.

A 2 to 3 mm wide bead of RTV sealant should be applied to the retainer flange.

Reinstall the crankshaft sprocket and timing belt, then run the engine to check for oil leaks at the front seal.

Lubricate the crankshaft journal and the lip of the new seal with engine oil and tap the new seal into place, being cautious as the seal lip is stiff and can be easily damaged during installation.

Carefully pry the seal out using a screwdriver or seal removal tool, ensuring not to scratch the housing bore or damage the crankshaft.
