Hissing Diesel Engine

Fiberglass insulation shouldn't burn. If the engine is cold, many things would work, even just a folded up piece of cotton, perhaps.

Good idea. That should tell you something, one way or the other. Diesel exhaust does not get near as hot as gas does. Less unburned fuel getting away I think.

Just be ready for a mess if the exhaust bolt/studs break.....right Chris?

Those aren't too bad usually. Once that thing is off it is wise to take a grinder and face off the manifold so the new gasket will seal. Often times the old gasket combined with carbon become "one" with the manifold. I have seen people just slap gaskets on and still have a leak.

You can usually tell if you are through the old gasket because the grinder will make sparks, no sparks=carbon/gasket.

I've been warned that this may be the case. We're spraying all nearby bolts with liquid wrench daily so it gets to soak for a WEEK prior to working on it. Fingers crossed.

Pblaster may be better...I have used it a lot in past:

Zep had a good penetrating oil. I usually look at what's on the shelf and pick the most expensive one, from an honest distributor of course.
