Discovery 5 - crank shaft failure on Si6?

[The Stiglet]

Hi guys, is the crankshaft failure only an issue on the diesel motors or is the Si6 petrol also impacted?

The Si6 is a totally different engine from the crank snapping 3.0 PSA V6.

thanks bakerstreet. Are there any problems specific to that engine or could it be the safer option?
