What is this????
OK, I'm attempting to replace a leaking intake gasket on an 87 base vert. Most of my motor head experience is pretty old. The car is from the 80s but my experience is from the 50s and 60s. A lot has changed so who will help me here?
I believe the item wrapped in the aluminum looking blanket pictured in the first pic is the EGR pipe and the second pic is an EGR temperture sensor.
Is that correct? How do they come off? The pipe appears to be part of the exhaust manifold, I have the FSM but it just says remove them.
And finally, can they be eliminated? No emissions test to worry about and while I was gonna keep this car very stock I'm starting to have a change of heart as I see all the crap attached to the engine.

Yes, you have identified those parts correctly.
The pipe has a two bolt flange on either end.
You can not remove these parts w/o possibly setting a Check engine light, unless you have the ability to tune out the EGR function in your ECM.
Here is a pic of the intake flange for that tube:
And here is the flange on the tube, itself...

OK guys, thanks. They are torx heads. I can't see the bottom bolts yet but I'll try feeling my way. As to asbestos, I probably changed 100 pairs of asbestos brake shoes as a teenager. We thought asbestos was a wonderful thing back in the 50s. I LMAO every time I see those guys in space suits removing asbestos shingles. Again, thanks for the help. I'll probably be back.

Interesting......
On my 1987, the EGR tube attaches to the intake with two bolts just like the pictures above, but the lower end attaches to the exhaust manifold with a crimped ring clamp. Also, mine does not have the heat blanket around it. It's an early 87, maybe it was a design change part way through the year?????

A replacement has velcro to secure the cover which quickly burns off.
I found some fibre-glas fabric with a aluminum cover to fab my own.
Secured with safety wire.

One way of solving the problem of the aftermarket heat shield with the Velcro that burns up (step one -- header wrap):
Step two: Put the aftermarket heat shield on top of the header wrap. It helps to make a new hole for the EGR temperature switch in the opposite corner to the existing hole to hide the seam. This reverses the way the heat shield mounts so the seam is not as visible.

Even if it was asbestos, you wouldnt know you had an issue for 20 years. And the little it would put out wouldnt be an issue. It takes long term constant exposure to cause problems.

It's fiberglass.

Again i want to thank y'all for the help. It's been a while since I took on anything this complex and I may be in over my head. The good news is I have plenty of time.
Also, I have to say that I believe somewhere around 1980 there were a bunch of engineers sitting at lunch laughing and laughing about how some poor sucker would one day have to take one of these engines apart in the car.

The bottom ring is an Oetiker clamp:
I got mine off by hammering a screwdriver into the ear to spread it apart. Crimping the new one on is a fun task thanks to the tight area. I used one of these:
