Cracked vacuum caps? Boost leaks? Vac leaks?

[BigTDogg (MA)]

So this is your problem? I have your solution:



Cracked vac caps from autoparts stores cause vacuum and boost leaks. Since many Z owners have deleted or re-routed many, umm, unnecessary systems, we have a need for vacuum caps in multiple locations.

Problem is simple rubber ones crack from heat and age. Here’s your solution:



With these:




I’m putting together a kit of EPDM rubber caps, 4mm and 6mm with constant tension zip ties. These caps are rated to 475°F and will not dry out and crack. They are also chemical resistant, so any splashes in the bay won’t affect them. EPDM is a very common material used in boosted car engine systems, for various components.


Comments, suggestions welcome.

Working on a new source. My initial sources won't hold boost pressure, only good for NAs.
