Has anyone successfuly used silicone blanking caps before or know of something better to use?
Deleted the IACV from underneath the RB26 inlet plenum so have some decent size (10mm OD?) air ports that need blanking. Ideally i would have crimped them shut and then run a bead of weld across them to keep them 100% sealed but the manifold is already on now so looking for an easier solution. Thinking basically a silicone blanking cap with a little sealant inside and then either a worm drive hose clamp or a spring hose clamp. Will be running up to 30psi so they will have a fair bit of pressure to be holding back.
Thanks for your help
