This gasket fits like a genuine gasket,
I thought gsf would be the place to buy from, as never had an issue prior to this.
Not sure if it’s all the BGA rocker gaskets that don’t fit but the t4/t5 crafter 2.5tdi isn’t anywhere even close to fitting. This one is bang on.
Elring one supplies may as well be genuine but at a fraction of the cost.
