Is water needed for X20XEV throttle body

[Nemesis]

I only had a brief look but it looks as if the throttle body has a water feed and return. Can these be blanked off?

Isnt it to keep the EGR valve part cool where the exhaust gasses flow through the TB

On a few x14-x16xe's ive took them off the TB and joined them together, not blocked anything, and theyve all been fine, no difference

Pretty much every car in the world has water through the TB to stop it icing in winter and sticking open.

I'm blanking the EGR as well as I have a Lexmaul manifold to go on it

Might as well try it blanked and if I get issues then reconnect it

Few of my customers cars who have Vauxallshave had this pipe bypassed by me.

No reported issues.

Reason of bypassing? Outlets of throttle body breaking.

Yeah im not surprised, it's a **** design.

I reckon I can use an XE main water pipe to lose the outlet on the engine, and just leave the TB outlet open.

It's one less pipe in the way, and one less thing to burst!
