hi i have noticed my car a xr3i running esc rs turbo engine has no amal valve is this dodgy.what does a amal valve do?
the car drives,boosts fine .70bar is this to much?
any ideas


also it takes 15-20mins in traffic to warm up and then when on motorway the temp goes back down to very bottom of temp gauge,but the heaters works fine and i have tryed earthing out temp sender and temp gauge goes red hot so does this mean my temp senders broke or a dodgy thermostat
