How is your EGR VALVE fastened? DOHC 2nd gen 97 SC2
 

Mine looks like a bolt on the front side and a stud w a puny bolt on it on the back side. Whoever reattached my egr to the rebuilt engine in there looks like they used the most worn out half rounded off bolts and nuts. Nice n rusty too.

After removal and cleaning, I'd like to reinstall it the way it should be.
Just a habit of mine
