C63 combination valve replacement

Guys need some advice please...

How easy is it to change the part circled. It’s the combination/air valve...

This is just a stock picture. My engine has everything in situ.





Many thanks 🙏🏽

It was pretty simple to remove and toss in the bin when I deleted that system. The hard part is removing the metal tube from the block on the (driver) left side but you don't need to do that.

I’m more interested in the steps to delete it haha. Saves me time figuring it out. What did you use for block off plates?

I’ve got a couple of valves here that work if you want one cheap.

Just did it last week to finish off the smog pump removal from a year or two ago. Removing them isn’t difficult. Just move the power steering reservoir and unbolt them really. The problem is the drivers side pipe that goes to the head exhaust side. It WILL NOT come out unless you move the power steering pump. So that’s what I’m working on now and it’s not very straightforward. When I figure it out I’ll post up any tricks, but the bolts on the backside are a ***** to get at.

You can get blockoff plates from VRP if you don’t mind dealing with them. You can also just make a couple out of sheet aluminum or fill the hole with JBWeld like Jasonoff did.

Cut the pipe an inch from the base and pinch fold it a few times then compressed the high temp JBWeld in the back side of the tube to make sure it's sealed.
