plenum chamber leak?

[ROR350]

how is the chamber sealed, is it a gasket or hylomar, is there any that could prove tricky, it looks straight foward, but i have been down that road many times!!

No gasket or sealant - just a good mechanical fit. You can check for leaks by spraying wd40.

Most use a sealant, silicone is OK, they did come out of the factory without, but advisable to apply some as you get about 27 inches of vacuum in there ( which is not far of complete vacuum)
