850 SL 2 Exhaust leak from manifold bolt

[Applachian]

There is an exhaust puffing out of the holes that hold the muffler support on the right side of the Cummins motor. One seems to have a broken bolt and the other is missing. Do yall have 2 bolt heads on that muffler stand?

Welcome to HEF @Applachian
We would love to help you out, but your description makes it difficult to know exactly how.
Would it be possible for you to post a picture of what you are trying to explain?

Got it. Thanks. This is the bolt (6). It was straight up gone and I wasn’t sure what was supposed to be there. Hole straight into manifold.

I really need a service book… maybe online?

The bolt should be M10 x 1.5 x 30mm
Those bolts usually have a habit of breaking from vibration - & are usually a blind hole - not through into the manifold. - perhaps someone got a bit carried away with a drill during a broken bolt extraction in the past?
Anyhow, you maybe lucky & simply screw a new bolt in there.
I always use antisieze.

Lost of vibration. Idle was set just under 800. Super L manual says I need to get it adjust to 900-1100. It is smooth 900 onward but real Lopey at the current 800 idle

Sorry to take the thread on a tangent but this is it. Desirable spec right? Average leaks and issues for age.

Looks nice, excessive vibration=motor mounts.

Thanks for mentioning, I’ll pay extra attention to that. Motor mounts= weight on hydraulic pump shaft if it gets bad (I hear).
