  1. My model of MX-5 is: __MK3.75
  2. I’m based near: __Swadlincote
  3. I’m looking for technical help or recommendations on: __ Purge Evap Valve

Got a little issue my purge evap valve solenoid starts clicking at idle after around 20mins of driving it stops if i unplug it, the clicking stops or if i turn the engine off then on again it goes away.

Not overly worried but when you first hear it you think its the rods doing a knock knock joke.

I did swap it out for a second hand unit but still doing the same thing.

Any Ideas?

What’s the question? Should the purge valve operate or should it be noisy?

Should it be noisy there is an audible ticking in the cabin

Purge valve dose tick in operation , normally the ticking is damped as the valve is mount on the intake rubber elbow nc1 maybe and later like you have on some other rubber mount so can’t really be heard , have you changed its mounting at all ?
