Blow-off valve question..
 

I had a blow off valve installed on my truck, actually the pipe from the intercooler to the horn/intake.. I was told it had an 11lbs spring.. My problem is i cant get it to blow off for anything, all i hear is the turbo barking..

Is it in the wrong location, am i doing something wrong, should there be a boost line pluged into it??

UGH!!


Thanks Guys..

what type of valve kit did you purchase? The BD kit I have uses the TPS to activate the valve.

All i know is its a Tail from what i remember.. I need to llook at it again, its in the shop at the moment..

It looks just like the BD one minus the chip looking thingy in the pic ha..

Also mines an auto and everything BD lists is for 5spds

the one you have will not work, if you want one that will work get a BD bov, but i hear they are a pain to get working right

great haha

If the one that you have is a normal style BOV for a car it will not work. Those use a vacuum "signal" line from the manifold to actuate. A Cummins doesn't make any vacuum in the manifold due to it not having a throttle body or anything to apply restriction in the intake tract.

I have the BD and it is a pain to dial in but once you get it dialed it works. Once you understand how to set it's easy. The BD works off off the TPS and boost.
