How to repair or replace intake valve?

The part should be replaced if it is broken down. Replacement process comes down to demounting the cylinder head, removal of a defective valve and installation of a new component. If there is such necessity, the sleeve and new valve oil seals are installed together with installation of a new valve.

These works should be performed at a service station. If an error is made during installation, it will lead to the valve and the cylinder head itself breakdown, and this, in its turn, will lead to expensive repair. Moreover, you need to take into account, that quite often, defectiveness of the valve leads to breakdown of other car units, and only qualified specialist can define and remove true cause of defectiveness. If this is not performed, component replacement in the car will provide short-term effect only.
