Re: 1990 EGR removal (TRWSD90)
You'll have to losen up your runners on the bottm,
and remove the bolts on the top to the plenum.
This way you can remove the plenum and get to the EGR valve underneath...

You can remove the plenum without loosening the lower runners but may need to smack it with a rubber mallet to jar it loose.
You will need a good quality 10mm box/open end wrench to remove the EGR valve.

When you get the plenum out of the way a wrench with a "S" bend will help you out immensely on the rear bolt. The rear bolt on the EGR valve is a bear to get to :yesnod:

Yep, the rear bolt is a tough one. I shortened (sacrificed) a box end wrench with a hacksaw so the it would fit down in there.
When you put it all back together, spray the new plenum/runner gaskets with Pam (the cooking spray). It will make getting things apart much easier the next time around and your gaskets will be re-usable, as in you won't tear them up taking things apart.
