Ex-Wheeler Dealers presenter Edd China once lost his cool restoring a classic Sunbeam Alpine engine.

The former star of the popular classic car restoration show was left frustrated after spending hours upgrading the engine as part of a build on the TV series. 

Edd struggled with the engine bay and described the work as one of the ”most frustrating jobs in recent memory”. 

He quickly lost his temper and started swearing as he worked after spending hours on repairs. 

The issue developed as the Wheeler Dealers crew restored a historic 1963 Sunbeam Alpine in an episode which first aired back in 2016.

Edd said: "The porting job on the Sunbeam engine was one of the most rewarding and most frustrating jobs in recent memory. 

"A partial upgrade had taken place at some point but without taking the time to do this job, we’d never have realised the full potential of that engine. 

"The first stage really involved quite a coarse fur or set of furs really just to remove a lot of metal reasonably quickly. 

"The idea is to get rid of any lumps and bumps and any inconsistencies but also to get rid of any sharp angles, particularly on the tightest curves. That way the air is definitely going to flow through but then we need to think of other obvious instructions.

"Now we are going to start using a little sanding tool, it's a little bit less aggressive and I can kind of work away at things like the flashing which is basically just excess metal left over from the casting process.

"I've now done all the coarse grinding and the sanding so now I've got a really lovely shape there."

However, Edd had spent four hours on just one cylinder, with several more to complete before the work could be completed. 

The pressure eventually took its toll on Edd who quickly lost his temper at the engine block as he erupted into fury.
