Hi, my friend has a 2003 4.4 Petrol Range Rover L322 (M62) BMW Engine.

I received a call the night before last to say he heard a loud bang and then steam coming from under the bonnet.

Upon investigating, we found a 3mm wide (roughly) crack down the back left corner from under the lip down to the bottom.
Any ideas what would have caused this please? My 02 V8's went in February this year, but I didn't get a loud bang and you still couldn't see the split in mine after it went.

Cheers.

I believe its quite common on the V8`s as the pressure is quite high. Use a TD6 cap which is 140kpa. The V8 is 200kpa 2007 TDV8 VSE
2003 TD6 gone.
2002 P38a gone
1999 P38a gone
1997 p38a gone
1993 VSE gone
1992 VSE gone
1966 Series 2a with V8 conversion gone

Cheers, was just worried that there may have been another reason to the severity of this break. I will be on changing this tonight.
