Description:
The four-valve technology is one of the sensitive parts of these otherwise robust engines: A regular replacement of the chain and its sliding elements is essential to avoid major damage. Combined with the sealing kit for the valve cover, you will receive all the parts you need to carry out the repair professionally.
Note:
For many vehicles over the years for cost reasons, only the upper shoe and the chain was changed. But even the lower shoe enters and becomes porous. Therefore, better anticipate the risk and take a look under the valve cover.
