Does anyone know what the part no, name etc of this part is? Needs replacing or swapping for something suitable.



It is fitted on a Golf mk1 DX engine in my camper. It is not a standard DX engine part and so must have been sourced for the engine conversion. I was thinking maybe it is from the old engine the van had (1.6 Diesel) or a bespoke part.
Any ides? It's rusted on the smaller section that is on the side.
Thanks
