Cali smog kit removal

[BS9ider]

Hi All,

Is there a technique to removing the air injection rail? The space is very tight and I'm struggling to get a spanner on the nuts without it slipping due to the angle.

Many thanks,

Stu

Only way I was able to get the injection rail off in my 77 was by removing one of the cam towers

Thanks Odoyle, that's not good news.

Success! I cut the pipe of with a Dremel which enabled getting a socket over the nut to remove.

Related to this topic - what are you all using to plug the holes? Looks like an M12/1.25pitch bolt?
Would love to hear the options.

Thanks!

Autoricambi has a set of plugs you can buy. They're a little pricey, but look much better than random bolts.

Thanks! I see them now. I've also located some bolts that will work but need some cutting:

Yep, I fitted the hex plugs which I purchased from Vicks.
