timing chain repair

Postby martyf250 » Tue Apr 17, 2012 9:30 am

I just made the appt at my dealer. I asked if they will use the updated parts. The service manager said yes. Is there anything I should ask or do to make sure they use the correct updated parts? Have the shoes/ tensioners been replaced and are no longer in circulation type thing

Not sure if you had a copy of the TSB, here is a link to the ClubFrontier.org website where they put a copy:

Just make sure they follow that, and make sure the PNs match.

So I've had the whining noise for about 5k miles now. Yesterday replaced belt and tensioner pully and crossed my fingers when I started her back up. Still whining. So what I'm wondering is how long can I go without taking it in for the repair because I have absolutely zero money for new tires I need first let alone $1500 for this repair. Can I perform the repair myself? Please let me know any options. Thanks

The repair is pretty involved, and you'll need a lot of tools. When I get home I'll try to find the step by step I read a while ago.

I also wouldn't push it too long. If your hearing chain noise, then the chain and the tensioner are wearing metal against metal, which means metal shavings are falling into your engine and that's never a good thing!

I recall seeing a step-by-step with pics on this forum about a year or 2 ago. Can't seem to find it now. Anyone else find it?

I guess I'm going to have to bite the bullet and get it done but will have to park it and ride my bike until I have enough cash. It gets better gas mileage anyway! Anyone know of a shop in the North Carolina Triad area that can do it cheaper than a the stealership, please let me know.

I'm in the triad area also and trying to attempt to avoid the dealer cost. I'm going to attempt to do the job myself within a couple of weeks.

Nikko7mge,

Let me know how it goes. I may end up doing it myself also if not too hard.

Just happened to catch this thread. My '05 path just started whining on acceleration about a month ago. It's continuing to do it pretty consistently - does that fit the symptoms here? What all is involved in the fix?

Sounds like it. That's the symptom mine had. The repair includes replacement of the secondary timing chains and tensioner shoes. I had mine fixed under warranty but the cost would have been over $1000 if I had to pay out of pocket. It's a fairly involved repair since so much has to be removed to get to the parts.

Damn. I guess I'll have to get it in to the stealership and have them confirm my suspicion. Then maybe I'll call around to a few local shops I've used before to see if anyone will do it for cheaper.

Wussup folks! I just registered today! I have a 2006 Pathfinder with over 114,000 miles on it and I've got the nice whining noise everyone is talking about. I've been driving on it for about 20,000 miles but I was just concerned if I continue to drive with the noise, will it slowly damage the engine? I took it to a dealer and they said $1700 out the door, parts and labor. I took to another mechanic and they said I shouldn't worry about as long as you don't hear the chain making noise. What do you guys think? Am I paying $1700 just to get rid of the whining noise or should I listen to the other mechanic. He said just to drive it as normal. I want a to get a third opinion from you guys. Has anyone ever heard of someone driving with the whining noise with no problems at all? Or am I going to regret getting this maintenance done in the long run and end up paying more? :?

I would say it's not critical that you have this fixed right away but after 20,000 miles it might be time to have it fixed. The whining noise is caused by the tensioner shoes on the secondary timing chains wearing out. My speculation is that eventually it will get to the point where it is possible that the secondary timing chain(s) will become loose and cause the exhaust valves to become out of time with the rest of the engine. Then you will have bent valvles and possible piston damage. If this happens, you will be paying much more than $1700 to fix the engine.
