Rb26 Tick Noise That Comes And Goes? Pcv Valve Anyone Had This?

[BLITZ-26]

ok so my RB26 developed at random this tick noise it sounds somewhat like pre det, i was concerned it would happen at low rpm if acc pedal was applyed or jabed etc.

however if you gently apply it, it will rev high into the rpm with nothing no noise and sometimes be gone totally ?

so i have a look around everywhere today looking for gasket leaks etc stethoscope every where as i thought it might be valve train or something nothing motor was quiet as a mouse, but it was still there

pulled the pipe off the breather and put my thumb on the pcv valve on and off and the loud tick came and went sounds exactly like it sprayed some carby cleaner into it and noise was gone then returned after a few minutes.

where do i get a PCV valve to check if this is the issue? and has anyone every had anything like this before? what as the solution ?

sorry to revive an old post, however did you ever resolve this?

My bnr34 seems to make a sound i believe is similar to yours, except it will only do it when throttle is jabed hard and engine is on full boost high in the rev range. pretty much anything engine related, tune, something loose possibly, has being elimnated so i am really lost! the noise can only be heard from inside, not outside the car.

when you had the sound, did it sound like it was coming from the middle of the firewall area/from engine bay?
