Porsche: No concerns over LMP1 engine despite Le Mans test issue

The oil leak that forced an engine change during the day of the Le Mans test on the #2 Porsche 919 Hybrid has been described as a "one-off" by the German manufacturer's LMP1 team principal, Andreas Seidl.

"It was a quality issue with one of the components in the test engine," he told Autosport.

"We have now understood more and it is something that doesn't worry us for race week - it was a one-off failure that we have never seen before."

Seidl would not elaborate on the nature of the failure.

The V4 petrol engine was replaced on the Porsche shared by Timo Bernhard, Brendon Hartley and Earl Bamber after the opening, four-hour session of the test.

The change cost the #1 car approximately 90 minutes of track time in the afternoon session.

Seidl explained that Porsche expects to take a step forward on its performance at the test, during which it trailed Toyota by more than three seconds in outright pace.

"We think that we will make gains from the pre-test purely from analysis of the data, but I'm sure Toyota will too," he said.
