Timing covers and gaskets

How you know it is this

• An oil leak from the front of the engine
• Oil on the belt or the underside of the car

Worth knowing before you buy

• A front cover leak is often mistaken for the crankshaft seal. Both need the same access, so they are usually done together.
• Many covers are sealed with a liquid gasket rather than a paper one, so the surface preparation matters more than the part.

Rest of the timing

• Timing chains
• Timing chain tensioners
• Timing chain guides and rails
• Timing belts and kits
• Camshaft adjusters (phase variators)
• Camshaft adjuster magnets / solenoids
