"What are the common issues with the 850CSi's V12 engine?"

Question

Accepted Answer

The 850CSi's V12 engine is generally robust, but after 30 years there are a few well-known areas to watch. Based on what I've learned from Road & Track and owner forums, the main issues tend to be:

**Cooling System**: The V12 runs hot and cooling neglect is common. Radiator, water pump, and all those little rubber hoses need attention every few years.

**Throttle Bodies**: Each intake manifold has its own throttle body, and when they fail (which they do), they're expensive to replace. Rough idle or hesitation is the tell-tale sign.

**Timing Chain Tensioners**: They can leak or loosen over time. Not a frequent failure, but when they go, it's serious.

**Electrical Gremlins**: With all the modules and connectors in these cars, electrical issues are probably the #1 headache owners report.

**Fuel System**: If the car sits (common with collector cars), the twin fuel pumps and bracket inside the tank can fail. Parts are getting scarce.

**General Age-Related Stuff**: Valve cover gaskets weep, vacuum lines crack, and all those 30-year-old rubber seals eventually leak.

The good news? This particular car only has 15k miles, so many wear items may still be fresh. The bad news? The listing doesn't mention recent engine service, so you'll want to verify what's been addressed.
