re. Cracked manifold, or broken bolt?

[Iain Mannix]

On my 87 5k, I could see the cracks in the manifold if I lay down
behind the p-side front wheel, jammed my head under the car and
looked up to the manifold - IIRC, the cracks were near 2 & 3,
easily visible from the bottom - once your head was aligned
with the comparatively small hole to look through.

That was the only place I could see the cracks.  Pside motormount
was shot, and the downpipe was cracked at the turbo/near
the O2 sensor.  Kinda hard to see them, but once I got
lined up & the light situated, there they were.....
