Hi everyone- My 2001 3.5 Pathfinder has a ticking noise that i've been trying to figure out. After closer inspection, it sounds like the noise is coming from my gauges...specifically my tachometer. Does anyone know what fuse to pull to kill the gauges? I promise I am not trying to defraud someone with false mileage reports, etc... Thanks!!

If it were valve noise wouldn't I hear it all the time and not just under load? If I pop the hood and give 'er some throttle (in neutral obviously) I hear absolutely nothing out of the ordinary. Could I be hearing lifters?

Bump...with update. I changed oil to Mobil 1, changed oil filter, and cleaned and oiled K&N filter...no change at all to the ticking noise. So switching to premium fuel and synthetic oil did basically nothing. Does anybody have any ideas for me?! Though the Pathfinder seems to fun pretty well, the noise is driving me up a freakin' tree :furious: Thanks....

Thanks for the response. I want to answer your questions and also revise/clarify a few things: The noise happens most noticably between 1800 and 3400 rpm and absolutely only under a load (acceleration). At 3400, it pretty much stops. It almost sounds like somebody is in the dash with a plastic stick beating on the plastic dash. On the drive to work this morning (30 min or so), the ticking happened almost from the get go, but about 3 minutes from the office, it suddenly stopped. It seems very random, and not related to engine temperature that I can tell. Oil...right now it is running dino 5w30, but I am a huge believer in synthetics (don't want to start the dreaded oil debate, but personal experience...) and am switching the Pathy to Mobil1 5w30 or 10w30 at the next interval (Pathy is relatively new to me). I change dino oil every 3k miles and synthetic every 5-7500. If anybody wants to chime in on the 5w30 vs 10w30 vs 10w40 debate I'd love some advice. I live in Denver where we have a couple of weeks (total) below freezing and very few days, if any, below 0F. The Pathy is garage-kept. Thanks to anyone who can shed some light on the noise and/or the oil...

Hi... I used to have a '94 SE Manual, and now I have a 2001 SE Manual. I had the exhaust manifold tick on my '94, which always went away when the engine warmed up. I have a very similar noise (but not exactly the same) on my '01, and I cannot figure it out. The noise is somewhat inconsistant...it seems to do it more when the engine is warm. It only ticks under accelaration and most noticably between 2200 and 3000 rpm. It doesn't seem to tick in neutral, so only when the engine is under load. I don't think it's pre-detonation because I'm running premium fuel. I have also tried a fuel treatment/injector cleaner that was recommended by a trusted mechanic. SO....am I looking at a lifter noise? If so, what are the implications of that? The motor has 69k miles on it and runs great...pulls hard etc. I just 1) don't want to cause engine damage by not getting this fixed, and 2) need to eliminate this noise that is DRIVING ME CRAZY!! Thanks in advance for the help...

Thanks for the quick response. Great to know that they will fit! Thanks. I'm not too worried about the speedo reading a little low...according to my GPS, the Pathfinder's speedo reads about 2-3mph high as it is now...so by going to the 265/70/16s, it should read about right!

Hi guys... first a disclaimer. I found this board today and have been reading for about the last 4 hours (with a dinner break). I have searched and read everything I could find on the issue. Now...my history. I used to have a 1994 Pathfinder SE 5-spd, and now, after a diversion into a few European sport sedans, I now find myself back with a 2001 Pathfinder SE 5-spd. It needs tires. I need an absolute answer on this: The stock tires are 255/65R16's. Will 265/70R16's fit for sure? Is anybody running them? Do they rub? I need tires soon, and I would really like to put some ~31" tires on there. Thanks for all the help and info on this board. I've gained a ton of knowledge on the R50 simply by reading. BTW: Attached is a pic of the Pathfinder on a 12,500 ridge (near Glaciar Pass in Colorado) and my 8-month pregnant wife

Hi- I had the same problem. The roof needs to be reset. What I did was yank the sunroof fuse. You could also disconnet the battery. This worked perfectly for me when I had the identical problem. Good luck!
