In appear to have two alloy pipes on my WUR I know the vaccum pipe from the ISV goes to one but this leaves one spare! What am I missing? The alloy pipe from the WUR that points towards the grill appears to be dripping oil?
This doesn't have anything going to it. It should have a black cap over it, this allows air in so don't push a plug over it, either leave it open or use the proper cap. There is no reason why this should have oil running out of it.
