i have a hks blow ssq off valve on my 98 impreza which has suddenly stopped working this morning. Apart from the valve maybe being faulty is there anything else that could have affected it? If the valve is faulty doeS anyone know of any problems that this model encounters and is an easy fix?
Car is boosting fine

thnx

 

If the car is still boosting fine then it may well be the Valve. Try taking the Valve off, take it to pieces, grease the moving parts, and retry.
