Donny Butt Posted May 29, 2020 Share Posted May 29, 2020 I am replacing the PCV valve on my 1zz-fe only to find out that there are two different parts! One has metric threads I believe! Which one am I looking for? Engine code is r3 if that helpsĀ Quote Link to comment Share on other sites More sharing options...
silvermatrix Posted May 31, 2020 Share Posted May 31, 2020 Hello Your best approach would be to remove the old and go to the auto parts store and compare the threads with the new one Quote Link to comment Share on other sites More sharing options...
XR2003 Posted July 10, 2020 Share Posted July 10, 2020 Unfortunately, yes there are 2 different threads for the pcv. Take the old part and use it to find the correct one. Quote Link to comment Share on other sites More sharing options...
