it's the common E3 mani problem, i grounded mine out, and welded it shut, no more crack. that's the cheap fix atleast !!

Unless it has a substantial leak(noisy) it ain't going to make much difference...

True, at least it isn't supposed to...

I've seen the E6 crack as well... Didn't really seem to hurt it...

take it off, grind the crack a little deeper then weld it.  Cast iron needs cast iron rods.

if it aint broke, dont fix it, the motor should stay put if it runs fine.
Your best advice so far was given to you already,,,,, read up and learn about this car and how it works.  You just stumbled into a gold mine of a web site, we all love these cars.

When someone replies to you about your turbo coupe,, i can assure you ALL of them know their stuff.

wait wait wait ......except me, i'm kinda a guessing guy,

true cast iron needs cast iron rods, but, that's for things that have to hold up a house, there's no excsive force on this thing, so it shouldn't matter, ( were still assuming that it's a full leak and not a crack,

I would like to see a manual vac/boost gauge reading, on this thing, for 1 or 2 trips to 60 MPH at WOT, see if it really is boosting,

The hissing, is it coming from inside or outside ? (was thinking brake booster, seen them make loss of boost )

outside, intake seals, turbo charge piping, yatta yatta

87-88 TC's dont use a vaspoogee booster. Its a hydraulic setup using electric pumps.
It's Gumby's fault.

I don't have a shop, so I think I will just grab a "new" manifold off of something @ pull a part.

The "hissing" noise, although gone, seems to still blow through the vets inside the car when the turbo is boosting...

How long will/should manifold replacement take?  I'm pretty experienced with fords (I have a '67 302 mustang) as is my g/fs father, who will be helping me; he owns a bronco.  But I have to admit this is my first non carbed car, is there anything I should know?

Look under your dash, or pull the cluster.  The rubber hose that goes to your boost gauge probably came off.  If I remember it right, the hose has a red stripe on it.

The crack is what I am going to deal with for now, I've bought a manual and I'm looking for a manifold at junkyards in my area.
