Just started my d16y8 build and i recently got a cheap ebay blow of valve so i can just get it out the floor and hook everything up, it will be upgraded as soon as i get money in a week or two so no worries about the reliability of this ebay one. Anyways i received it yesterday and i realized there was a little nozzle sitting around in the package and a hole in the back where it look like it could screw into, my guesses are that it snapped off but my knowledge about this is not much thats why i rely to you guys. below are pictures attached help is greatly appreciated. thank you guys

 

It would be helpful to see the "little nozzle" that was in the package as well. It looks like something was threaded there that came out. That little hole shouldn't be there.

 

I dont know if i confused you with the term "nozzle" since maybe it has a different name, but its the thibg that i am holding on my left hand.

 

Nipple be the name! Anywho.. Where it is is where it belongs. The other hole is a mystery so far.

 

Return it ! that looks like a POS! you should only have 1 vacuum source! Should of at least got a TIAL replica. Just return it saying it looks damaged! and buy a real TIAL Q BOV or CHINA TIAL Q if your gonna buy a replica of any kind.

 

If everyone stops buying cheap Chinese copies of genuine quality products, those scummy companies would wither and die. Get the real deal... buy once and cry once.
