Well I finally fitted a dump valve today.....after all these yrs putiing it off..
Anyways, so fitted it on and when it came to put the small spacer in the re circ valve, it already had one fitted!! So in all last yrs pushing 300 odd brake and at 1.1 bar having a disabled re circ valve with no dump valve must not have done the turbo any good?
what sort of damage could it have done to it???
