squealing recirc valve

[Richie-LCR]

Hi

just picked up my new lcr this morning and have found that when you let off the throttle rather than have the normal woosh of the recirc valve i get a squeal like an old bed spring lol

what would be causing this? would i be needing a new spring or a rebuild kit? would like to keep the cost down just now as i've got a rolling road day to go to next weekend so idealy want to buy one or the other not both if possible

cheers
Richie

EDIT; its a forge 007p valve btw

Just get a service kit from Forge, comes with new piston, all new seals and new grease. There either FOC or only a few ££

you probably need to swap the dv around, i.e. swap the 2 larger pipes around and this'll silence it

If this is a forge DV then the top might not be screwed down properly.
This happened to my one when it was fitted.

cheers i'll try the two quick fixes today and see what happens if not i'll order a rebuild kit

all sorted now, turned the valve round and the squeal is gone only thing i noticed was that the spring in the valve is silver and not any colour off the forge website so i think i will invest in a yellow spring

depends on the power your running. the colour of the spring determines the strength, not sure which is which. worth asking forge.

Green - 5-15 PSI
Yellow - 15-23 PSI
Blue - 23-30 PSI
Red - 30 + PSI

Richie-FR what power you running??

Those are'nt boost pressure's though.....

 

[Richie-LCR]

unsure of the power figures but the boost spikes to over 20psi on my gauge(gauge only goes to 20psi then drops off to 17ish so im assuming its remapped and the fact that i left my mates 230-240bhp saab for dead on my private road confirms this

 

[jordyboy004]

so is green softest and red hardest or the other way round. to me it makes sense that the more boost you got the harder the spring so green being soft. just want to confirm tho. only i have too silver springs, one soft and one hard. my boost gauge reads around 11 psi so out of the 2 springs i need the soft one.....right?

Green is standard...soft
