Just in case you aren't quite sure what you are looking for: The EGR CTO
should be low on the driver's side of the block, between cyl 2 and cyl
3. It looks like a brass pipe fitting with a plastic piece moulded into
it. The plastic piece should have three vacuum ports set at right
angles. Originally there should probably have been a second CTO for the
ignition vacuum system located between cyl 4 and cyl 5.

If the headers don't connect to the bottom of the intake manifold,
wouldn't that be a honkin' huge vacuum leak every time the EGR opened?

If air goes from the breather TO the valve cover here... why does oil come
back in there? maybe thats a silly question, its only a lil bit.

Was new when i bought it, it had been replaced, what else should i look for?

Im guessing its in limbo because its hooked to nothing.

Ill plate it off then.

Not really a vacum line... but the fresh air line going to the valve cover,
thats the only thing.
Heres a link to the previous pictures and some new ones i hope helps.
