ticking noise and low idle fluctuation...

[Sinful7m]

not sure what it could be but there is a ticking noise coming from around the radiator not necessarily loud but im a stickler when it comes to these things and i cant put my finger on it,also an idle fluctuation to about 600 rpms that doesnt raise or drop already checked for vaccum leaks...any help would be appreciated

your fan (if the noise is near your rad)? I'm thinking its your valve shims.. causing the noise AND the idle flunctuation.. have you check if they are in spec?

thanks havent checked to see if they were in spec ill check tonight if it isnt too cold its a subtle ticking near the radiator just picked this car up about a month ago to use as a daily due to me not wanting to drive my other supra everyday its a basicly stock 89 turbo with an mbc and a full 3 inch exhaust i was also thinking it may be the waterpump
