A customer’s 1991 BMW 850i V12 rolled into The Car Edition garage with a host of problems — burning oil, misfiring, and leaving a trail of blue smoke in its wake. With just 88,000 miles on the clock, this 5-litre, 300 bhp grand tourer clearly deserves a proper second life — and that’s exactly what it’s about to get.

In the first part of the BMW 850i V12 heads rebuild series, Car Edition mechanic Gytis kicks things off by removing the entire engine from this legendary coupe.

The rebuild plan includes:
1. Full engine removal
2. Cylinder head rebuild with new valve stem seals and guides
3. Inspection of pistons, cylinders, and gaskets

This video marks the start of a multi-part series that takes a step-by-step look at the process of restoring this iconic machine. From diagnosing oil consumption and misfires to breathing new life into the engine, we’re showing it all.

If you’re a fan of classic BMWs, V12 powerplants, or just appreciate precision mechanical work done by hand, this is one series you won’t want to miss.
