hi guys im new too the ford world so am still learning lol. ive got a 89 s2 and the amel valve is clicking away when warm. questions i have:-
what doe the valve do?
can i disconnect the electrical connector and what effect will it have.
should i replace it?
is there a known wiring fault with the system.

ive done searchs and the general result seems to be you just disconnect them. is this correct?

any help appreciated

thanks

The Amal valve is the boost control solenoid - the ECU uses it to try to control the boost - cut it if inlet temps get too high, and to limit boost to a limit specified in the chip, and to bring it in as hard or as progressivley as the chip's author desires.

You should hear it click a little when you turn the ignition on, but it shouldn't be clicking its nuts off while idling. If it's clicking that's a good sign that it's working - clean the contacts in the connector and on the valve - might just be intermittent contact.

Disconnect it and you'll have limited boost which will be determined by the preload on the actuator, and the ECU will have no boost control either.

Some people swap it for a bleed valve, which predates caveman technology, but if set to low boost really isn't much of a problem. There's still no ECU control, but you can have the boost set as high or as low as you want, just by adjusting the bleed valve.

 

my mate had an s2 that did that... cant remember what it was doing it but his car was a piece of junk lol think he swapped it for a bleed screw...

 

may be the tps isnt set right that cam cause this

i think i will go with manual bleed valve and jut to away with the amal valve. will it cause any long term problems leaving this unplugged?

It will cause no problems leaving it unplugged, but do not fit a bleed vavle yourself!! Take it to a tuner and have them fit it and set it up or you will just destroy your engine mate!
