90 4runner making ticking noise

Hi all,

I have a 90 4runner 22re making a ticking noise. It sounds to me like a fuel injector but as I am not really a mechnic this is only a guess. vehcicle seems to run fine, but that ticking sure is getting on my nerves.
Last I checked the fuel milage it was 18.6. Its a 5 spped. Does have this weird idle thing going on though. I set it at 950 warm, when its cold it hits 1500-2000. Then sometimes when it warms it will go down to 500rpm. this is not constant though. It actually idles smooth. Any ideas would be greatly appriciated.

Thanks ahead of time.

u have to be more specific about that noise; when does this happens?, when u drive it?

Hi, thanks for the reply.

The noise is happening all the time, its a constant tick, tick, tick. It is only noticeable when I am out of the truck or if its very quiet at a redlight. I am almost positive it is not coming from the valve cover. thanks again.

egr valve?

From expereince and from a Toyota master technicoan mouth, if the 22re is making a small, repetitve, "ticking" you are are fine. It' s a good sound, from a healthy 22re motor. 22re motors are famous for this soft repetitive ticking.
