Fernando Alonso was forced back into the McLaren garage after just a single installation lap this morning, with Honda diagnosing an issue with the engine's oil system.

The problem is apparently located at the front of the V6 hybrid power unit which would require a proper dismantling of the engine in order to further investigate the issue.

"We have an oil systems issue which requires a full investigation," said a Honda spokesperson.

"We plan to run again today, but due to the difficult access location it will take several hours to resolve."

Red Bull's RB13, with Daniel Ricciardo behind the wheel, also had a troublesome debut with the car stopping out on the track after a handful a laps, halted by a benign sensor issue, and bringing the red flag.

Red Bull is expected to rejoin the session shortly however.

Phillip van Osten

Motor racing was a backdrop from the outset in Phillip van Osten's life. Born in Southern California, Phillip grew up with the sights and sounds of fast cars thanks to his father, Dick van Osten, an editor and writer for Auto Speed and Sport and Motor Trend. Phillip's passion for racing grew even more when his family moved to Europe and he became acquainted with the extraordinary world of Grand Prix racing. He was an early contributor to the monthly French F1i Magazine, often providing a historic or business perspective on Formula 1's affairs. In 2012, he co-authored along with fellow journalist Pierre Van Vliet the English-language adaptation of a limited edition book devoted to the great Belgian driver Jacky Ickx. He also authored "The American Legacy in Formula 1", a book which recounts the trials and tribulations of American drivers in Grand Prix racing. Phillip is also a commentator for Belgian broadcaster Be.TV for the US Indycar series.
