I’m getting oil in the air filter box so thought I would clean out the tower. Held on by 4 studs. I failed to remove it. Wiggled and tapped it but could not get it free. Does it just pull off. In that the van is off on its travels for 2 weeks I sprayed everything in WD40 and will have a second attempt when it comes back from the surfing beaches.
My concern is that one stud came out and the shaft is quite rusted and thin and I don’t want to snap them. Where can I get the studs part number and where would I buy them. My VW dealer rarely seems to have any parts for my van.

Many thanks
