The fault
How you spot it
The rocker cover gasket goes porous from 130,000 kilometres and oil leaks along the edge of the cover. Because of the V layout it happens on both sides.
The escaping oil can drip onto the hot exhaust, which gives smoke and a burnt smell, and in an extreme case a fire. The visible signs are an oil patch under the engine and an oily engine bay.

How we know
Information, not an expert opinion
We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.
- A fault on the list does not mean the car you are looking at has it.
- A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
- You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
