I think Bill R recommends getting a BMW gasket from the dealer - logical as a small premium for a superior product perhaps means longer life.Originally Posted by Blitzkrieg Bob
When I did my head gasket (twice due to not using washers on hex bolts the first time - not because the gasket failed) my first gasket was a Reinz and the second a genuine one from BMW because I couldn't wait for another one from BMA - they were chalk and cheese - the BMW appeared far superior.
Still OK after 30,000 km (touch wood).
