UV Dye Leak Test — The Right Approach
A small amount of oil seepage on valve cover gaskets or camshaft seals is common on higher-mileage A7 engines and often stabilises. A true oil leak — visible drips on the ground, burning oil smell, rapid oil level drop — needs immediate attention. In Malaysia's heat, oil on hot exhaust or turbo surfaces burns and creates smoke that owners often mistake for a cooling fault. At 4M Car Care we perform a UV dye leak test to pinpoint the exact source before recommending any gasket or seal replacement. A7 cam cover gaskets cost RM 180–350 including labour.
