i was installing boost bolt and noticed that there was a bolt missing on the intake manifold heres is a picture i found online of the location of the hole.

5.9L Cummins Turbo Diesel OHV 24V Inline 6 Cylinder Engine for the 2007 Dodge Ram 2500 #38462809 | GTCarLot.com

in the picture it is the hole on the raised up circle. there are threads but no bolt wondering if there should be a bolt there? thanks

That's for the ground bolt on the grid heater. Yes there should be a bolt you're loosing boost out it.

are you sure he'd be losing boost? there usually are no bolts going into manifolds like that without being sealed somehow with an o ring of thread tape or something like that

There's no bolt there, yes it was for a ground for the grid heater. But since cummins uses a graphite gasket there's no need for it. Graphite conducts electricity.

i'm talking about a gasket or o ring to stop air leaks if its actually plumbed into the manifold. which i seriously doubt.

No there shouldn't be a bolt there and no not losing boost out of it, hole doesn't go through intake plate.
