One of the main systems determining the performance of your Ford Focus is the valvetrain, and keeping it in good, well-tuned condition is crucial for optimal engine operation. Besides, much depends on the valves themselves, their seals, springs, and guides. Each valve is designed to provide good tightness of the combustion chamber when closed, and its stem moves inside a special guide, while the valve seal doesn't let excessive oil into the cylinder. But over time, the seal loses flexibility, deforms, and fails to trap oil that leaks along the valve stem.
It's generally one of the main reasons why the engine with significant mileage starts to consume more motor oil. In most cases, it's enough to replace the seals; many engines allow doing it even without removing a cylinder head. But when it comes to more serious engine rebuild, it often makes sense to replace valve guides as well, as worn-out guides develop a play making new valve seals serve much less than they should. All these and lots of other products you might need for the repair job are available in our Ford Focus valves & valvetrain parts collection.
