I know this has probably been asked before but i can't be bothered to search tbh, but i finally got a standard one (froma classic but newer than my '92), anyway it looks huge compared to the pipes currently coming out of inlet pipe etc.i'm sure i can sort this, but which pipe will go to which bit of the valve? i know the one from the manifold goes to the top, but the currently blocked of hole on the inlet, does it go on the side or bottom bit of the dump valve?

 

In that case I can't be bothered to answer your question tbh

 

it was only a matter of time before i got my first troll post reply! well done fudgepacker you are the first!
its a simple question, and i have done a search since, but can't really find a definitive answer, can anyone post a pic of an engine bay of an old classic with a standard d/v fitted please?

 

sti?

 

sorry perhaps its the beer but i don't quite get that one lol!
I have a wrx, but surely all early engine bays look the same
anyways if you have a pic please post one
cheers

 

thought i had but dont.....

 

The std dump valve has an arrow embossed on it showing the direction of airflow I believe

 

yes as elmer says there are arrows on the valve itself indictating airflow direction.

 

any help?

 

cheers for the help guys, but looking at the d/v it doesn't have any marks on it showing direction,

 

If yours is the same as mine then the bottom port is the inlet from the intercooler and the side port the outlet back to the intake tract.
