I have an '86 GL-10 turbo w/5sp manual and 4WD. Just gave it a third engine. This EA82 is slighlty newer... The only differences are in the manifolds.

The intake manifold doesn't have the 3 hose thermo regulator valve at the rear, nor the solenoid valve on top.
I got everything connected and it started but ran really rough while cold, and didn't hold idle well when warm either. I heard a hiss and discovered a fitting at the back of the throttle body. It looks like a perferated bolt, there is no hose barb, its possible one could have been broken off at some point, but it seems awfuly smooth for that. I put my finger over the hole in the fitting and everything smoothed right out. I popped in a threaded plug from an old manifold and it runs fine.
What is this fitting? Does it need a different fix?
I don't have the vac diagram for this manifold. I can't use the old manifold because its cracked.

A smaller concern is the connection of the vaccuum line at the air intake. The new engine has a single "L" which connects to the vaccuum line with the flow valve. The old engine had a "T" fitting coming out of the intake with an additional line running to the canister. I left the "T" connection, but I don't think it matters much, right?
I'm not getting any error codes,but I'd like to be a little more sure before I take it out for a road test.
I've pulled a ton of info off this board searching, but this one I have to ask.
Thanks, DasWaff

I still haven't found the correct vaccuum diagram, but some of the older, similar ones suggest to me that this fitting is for an automatic tranny. Does that sound correct?

Probably the vacuum fitting for the vacuum modulator, which you don't have.
