My inlaw's 1997 E350 motor home has 2 broken manifold studs on the passenger side. The rearmost top and bottom. They are broken off flush with the outside of the manifold.

Should I try to just get those 2 out without pulling the entire manifold if that is even possible or should I just pull the whole thing and not screw around?

Anybody else been here?

 

I know this is no answer for you, but I've had the manifold bolts busted on passenger sidiefor a long as I can remember. Because of the size of the vehicle (over 9000 lbs), it's not subject to emissions so it passes inspection without having to be looked at. I've never worried about them.

 

Are they causing a problem other then being broken?

 

No problem other than a little soot but not really any exhaust leak that can be smelled. Are the exhaust valves in danger if getting burned?

 

A/F ratio would be the best way to see the burn condition along with checking the plugs.
