D3 S8 V10 - Cheap to Buy, Expensive to Own (Major Engine Repair)

In this episode, I dive into the chaos of owning a legendary yet temperamental Audi D3 S8 with the Lamborghini-derived V10 under the hood. What started as a mild misfire turned into uncovering a massive oil leak — the kind that makes you question every life decision leading up to buying one of these beasts. I walk you through the diagnostic process, the parts I replaced, and the real-world pain (and satisfaction) of wrenching on a car that was never meant to be cheap or easy to maintain. From valve cover gaskets to coil packs and plugs, it’s all here.
