I've been following the write up at rotary resurrection on how to do delete the emissions on my S5 TII engine.

Everything is clear to me except on what to do with this water connection to the throttle body.

I couldn't see in the pictures too well if it was something I was suppose to block off or not.

I blocked the one on the back of the water pump and the one sticking up from the rear iron.

Should I block this off? Fill it with RTV and vacuum cap with clamp?




oooo realized I spelled emissions wrong in title Z.Z

 

Will you be keeping the thermowax or not? sounds like no if you've removed and pouched the coolant line in the back of the motor that I think connects to that port

 

I haven't sealed any of the three holes yet.

I don't want to do the throttle body mod yet seeing as it's a freshly rebuilt motor and I'm just trying to get the thing running.

I'm running a Haltech Sprint.

So that coolant spot I pointed out in the picture is routed to the top of the rear iron?

 

My memory is a bit vague on it, but I'm fairly sure the rear iron coolant line goes to the uim/Tb area for your thermowax and bac. I would keep it for now since if you're wanting to get itrunning first, I would go for reliability first and shoot for removing lines later on.

 

I'm running the Sprint RE and had no connection for the bac valve on the side of the UIM so I blocked it off.

I just remembered that I replaced that line once on my old TII and I recall the rear iron connection going to the water pump connection.. I think..

That car also had the emissions deleted when I bought it so it may have just been rerouted. But that still leaves me unsure if I am going to need the one on the back of the TB.

 

I cut a nipple off the Tb and cleaned it up to "bare bones' when I had the S5 TII in the car.
I can't recall if that part is held on with the philips screws or not,but it can come off since you won't use it.
It recieved coolant so it won't have any vacuum leak to be concerned about.

 

And the other two just block off? (water pump and rear iron)

 

You can block those off with rtv and a cap.

 

I used an N/A waterpump as it has no Nipple for the Turbo.Since I was not running a stock turbo I just changed the waterpump when I built up the engine.The other outlet and the rear iron,Yes,I just ran some hose and a Cap on each,then clamped it.
