Maintenance issues were already obvious, but the fact that even the rubber seal on the oil filler cap had never been replaced<\/strong> really says it all.<\/p>\n\n\n\n

When the rubber seal on the oil cap is used for too long, it hardens and no longer seals properly. That\u2019s exactly what happened on the T5<\/strong>, with the predictable result: oil escaping where it shouldn\u2019t.<\/p>\n\n\n\n

After thoroughly cleaning the engine block<\/strong> and replacing the oil filler cap seal<\/strong>, the oil now stays exactly where it belongs.<\/p>\n\n\n\n

The spark plugs were replaced<\/strong> as well as part of this service.<\/p>\n\n\n\n

When replacing the tailgate<\/strong>, I didn\u2019t swap the lock at the same time. That has now been taken care of too, finishing off another small but important job.<\/p>\n\n\n
