Tappet ticking
So I was topping my wash water up today and left the engine running and noticed what sounded like noisey tappets, not overly loud but definitely louder than the actual sound of the lower guts of the engine turning, both sides of the rocker covers too.
Checked oil level and its fine and only 2000miles old 5w40 castrol, Then I found this info which has confused me even more Audi 4.2 V8 TDI Engine Problems and Reliability 1. The V8 4.2 TDI diesel engines are excellent concerning reliability. However, some of them had problems with the intake manifold and throttle. 2. All bearing of axes, rods, and levers inside were made of plastic until 2009, which wear out very quickly (40-50,000 miles). As a result, reduced power and torque because of different gaps and skews. New ones replaced this weak parts later, and problems with them never happened again. Modifications BNV - 326 hp and 479 lb-ft version Audi D3 A8 4.2 TDI Quattro from July 2005. BTR - 326 hp and 561 lb-ft engine for Audi Q7 4.2 TDI. CEM - 349 hp and 590 lb-ft engine for Volkswagen Marine TDI 350-8. Any one know anything about the above or had similar issues? |
