Dump Valve stuck jammed

Looks like my blitz DV is stuck in the closed position.

Will driving off boost cause any issues ? I was worried about any back pressure occurring and blowing something.

Just need to make a 40 mile trip to get it sorted as the bolts have rounded off and I can't get it off .

are you sure its not a vac pipe for boost reference ?

that being said in answer to your question there is lots of bebait about if running no bov has any negitive affect so im sure you will be fine even in boost, as some run no bov with a large single turbo

if you are still running stock bov as well there is no issue at all , if you have no bov at all there is no real issue either , the only sight issue you would have is if you have a maf sensor but still no real issue at all just may run rich slightly when bov should be active
