For the last few weeks I think the car has really been dodgy when idling! Sometimes it will tickover high, sometimes it will want to cut out.

Could a dodgy dump valve cause this?

It sticks all the time and I think is shagged

 

Yep if the dump valve is fucked it will make an air leak

 

Ahh, I will bust out my mums broom handle later then

 

What dump valve have you got on there?? you need a bailey twin piston dump valve as they are ment to be the best one's to use.

 

It is some shitty one!

Top gear or something? I cant remember the name...I got it with the car!

How much am I looking at for one of those do you think?

 

This guy's got one for sale

Thanks for your help fella

 

Sorry to interupt but an air leak will make the engine cut out or idle lumpy...........

 

Thats what I said

I might not have explained it well

I will try it with no dv tonight and have a setup in the morning at Jamsport so will see what they say

 

Ah right i missed the high idle bit. Theres not a lot you can do to make a RST tick over too high, have you checked the throttle cable is all adjusted up right?

 

I am gonna take the DV off and play about with it tonight

then Jamsport tommorow so hopefully they will be able to sort it if i cant

 

The dump valve shouldnt really make it play up if its a twin piston. You would be surprised what can effect the running of an RST........

 

I dontthink it is a twin piston! It is some shit one!

 

There are twin piston ones around that don't carry a name badge.

Another thing i thought of? Do you have a vacuum gauge? And can you see the pistons through the holes in the DV?

 

safechav you spaceboy,read the thread rite,he already said its a top gear one or summit,and not a double baileys (with ice),

just get rid of the dumpy alltogether.

maybe your air leak is brake servo related ,(120quid), mine was,and im letting everyone know.
