Postby novaman » Wed Apr 20, 2011 9:11 am

hey guys I have been noticing more and more when I start up my pathfinder there is a lot of engine noise it high pitched and kinda loud..like a whine....you can here it most of all in the cab..when you push the gas it gets louder.

Take it to the dealer, you have timing chain/tensioner issue. Free fix that will be about a day and it'll cost Nissan $1500+ to fix.

I had the same issue but they said that wasnt it. They just replaced some of the belts because it was time for new ones anyway and sprayed some oil and the noise went away.

I just had a similar noise on my 06 SE. Turned out it was the aftermarket oil filter which didn't have a check value.

Mine has been making the same whining noise at startup but then goes away after a few miles and will not happen again until engine gets cold started again. Still not sure if tensioner or timing chain

My 08 Pathfinder has started making this noise LOUDLY lately. Time to take it in, I guess. I hope it's NOT the timing chain issue as it has just under 90k miles on it and is no longer under warranty :(

Damn you people & your warranties. 110k on my 06 path

I'm sure everything will start going wrong now :cry:

I hear you webmastir! Since rolling past 85k there's been more clicking, rattling and now whining than ever :( May be time to unload the truck...

Indeed it was. I thought it would be the timing chain, but the dealer said Nissan oil filters have a check valve that opens when the pressure gets too high. I had gotten my oil changed at a quick-lube type place and I suppose the filter they used didn't have this and was making the noise.

I have never seen this before on any cars after oil changes at this place, including my wife's '08 Altima.

I just got booked in tomorrow for the same issue... $1350 at Sunnyvale Nissan. The way they described it made it sound like a design flaw to me...

So is this a common problem? Was the timing chain just loose?

My repair ended up costing me just under $1400....$390 for parts, $1k for labor - OUCH. :cry:

Things like this should NOT be failing on this vehicle - even at 90k miles. VERY frustrating.

And yes, seems like a known issue/possible design flaw.
