kefferjoe Posted April 18, 2015 Share Posted April 18, 2015 (edited) Hello, I just bought a 01 Pathfinder. Found it on Craigslist for $2100, it's an 01 with 145000 actual miles. It is the 3.5. However the guy was getting rid of it because it has a noise coming from the passenger side valve cover it sounds like a pen tapping against a metal trash can lid, and it speeds up with rpms. I assume this is a bad lifter. However I know the 3.5s have shims. I tried some various auto parts shop remedies and nothing really worked so I am going to take the valve cover off and look at replacing the lifters or something. Does anyone know of a how to guide or any tips before I get started? Also where is the best place to buy replacement lifters, and how long should this job take me?

kefferjoe Posted April 18, 2015 Author Share Posted April 18, 2015 Also had codes P1110 and P1145 which is RH and LH Intake valve timing control sensor Link to comment Share on other sites More sharing options...
bushnut Posted April 19, 2015 Share Posted April 19, 2015 I'd replace the sensor first and see where that gets you. Link to comment Share on other sites More sharing options...
Precise1 Posted April 19, 2015 Share Posted April 19, 2015 ^Exactly. Download the FSM from the pinned thread in the Garage section, follow the trouble shooting details in the EC section and then replace if necessary before you start digging in.

kefferjoe Posted April 19, 2015 Author Share Posted April 19, 2015 Could faulty sensors be causing the clicking noise? Link to comment Share on other sites More sharing options...
kefferjoe Posted April 19, 2015 Author Share Posted April 19, 2015 Also I erased the codes and they haven't come back since Link to comment Share on other sites More sharing options...
CNAM Posted April 21, 2015 Share Posted April 21, 2015 Could be timing chain or chain tensioner related. Link to comment Share on other sites More sharing options...
fixinto Posted May 21, 2015 Share Posted May 21, 2015 not sure about the VQ but on the VG passenger lifter replacement wouldnt take long at all. after you pull the valve cover you have a few bolts holding the rocker rail on and after those come out there is the lifter guide plate, lifters will pop right out. Be sure the cam is on the flat side when you torque the rocker rail back to spec. or bad joo joo may ensue hehe. as in breaking a bolt off trying to torque it to 16ft lbs, seen a guy do it. he was not happy at all. pat Link to comment Share on other sites More sharing options...
starbai Posted May 20, 2016 Share Posted May 20, 2016 Not to thread jack, but OP I juts bought an 02 Pathfinder as well and Its clicking/ticking like crazy. Here is a video I took of it, is this what yours sounded like? What did you end up doing to fix it? did you do the lifters? Sounds like a damn rattlesnake and its very loud for me.
