P3rks 11 Posted September 8, 2013 I'm just doing some work to my VR6 and I've just noticed a valve inside the thin water pipe which goes to the throttle body. I've never noticed it before. Is this normal and what is it for? Quote Share this post Link to post Share on other sites
Jim Bowen 1 Posted September 8, 2013 Apparently its a one way valve. I lost mine and now got a massive one I had to buy and connect the pipes to. Quote Share this post Link to post Share on other sites
P3rks 11 Posted September 8, 2013 Oh right. Bizarre that I've never noticed it before. At least it's normal. Thanks Quote Share this post Link to post Share on other sites
