R53 Engine Question

Hello all. Been trying to search the inter-webs for this information and seems to come back as a mixed consensus so bringing it to the experts here. Is the W11 engine in the R53 interference or non-interference?

it absolutely is a interference engine, but it has a 4 tooth skip clearance with stock internals so it's rare to see bent valves
