I have a 2005 Nissan Pathfinder with the 4.0 liter engine. Upon hearing a growling noise coming from the engine, I took it in to Nissan and they quoted me $1750 to replace the timing chain because the plastic gizmo the chain rides on was worn out.
Is this a recall item and what warranty will I have if I have it fixed? Do the same plastic parts go back in?

Re: timing chain wear
That is correct. If your engine is whinning at about 2000 rpm's and its a high pitch whine, you need upper timing chains and chain tensioners. aka plastic gizmo as you called it. The timing chains ride off the plastic portion of the tensioner causing the noise, basically the chain is riding on steal stub from within the tensioner, that's where the noise is coming from. Waranree on this is 5years or 60000 miles which ever comes first. And the new tensioners are updated parts.

close to 1900.00.sorry.contact nissan.im assuming your hearing a loud whining noise from engine?nissan is aware of this situation and issued atech. service bulletin to address it.from what ive heard the reason for the premature tensioner guide wearthrough and subsequent noise is because the offending secondary chains wrer made to "rough"when manufactured.the replacements are much smoother.like i said nissan is aware of "defect" they may help you out.1-800-nissan1
If you put that description into your search engine,I believe you find a lot about your vehicle,you may not want to know.
I was thinking about a low milage 2008 or 2009 frontier,so I have been checking
I believe you have timing chain issues
2005 on, are 2nd Generation, and have that,so maybe your smaller engine, does as well
timing chain life span varies, it depends on what type of driving u do, for instance heavy on the throttle wears ythem out faster from the streaching this causes, but at 160,000 miles the noise u are hearing is likely a loose timing chain, replace it before it comes apart and damages the engine. This job is not for the home mechanic, it requires special tools and a high degree of skill and a factory service manual is a must.
I just had the same issue with the same mileage as yours. Mine is the sending/sensing unit and it causes the range, distance to empty, etc. to be incorrect. The dealer is replacing for just under...$500. Another problem has been a whining sound under the hood, which they diagnosed as worn timing chain guides...cost to replace the guides is about $1,400. Not replacing results in the chain running on metal and chain wear, not to mention that whine. The service advisor said these two issues are the most common problems with Pathfinders. Good luck with your problems.
The timing chaing noise is very common on almost all v6 nissan engines. There is a significant difference for the maxima's though.
Timing chain noise is very common and it is the result of the secondary timing chain tensioners. They often stick and put too much tension on the chain and the plastic guides for the tensioner wear down to metal and that is the noise you hear.
At Nissan, I have performed this replacement many times and I suggest you take it to the dealership to have it fixed.
timing belts and chains are 2 very diff things, belts are rubber and wear out in about 80,000, chains are well chains and made of very strong steel they will last the life of the engine in most cars and trucks but not all cases. there is no recommended change mileage by any manufacturer, if the engine is torn down for an overhaul then yes it is wise to replace the chain, but only then, otherwise it is a very expensive waste of money.
same thing, get a used engine, ill sell u mine with 135K miles..
first it was my transmission at 87K, the whining came at 60K miles, but it costs 2K to install, just dump it or bring back for trade in, those dicks..
I am going to take a guess and say, that you check engine light is a EVAP leak and you will need new VENT CONTROL VALVE and a WATER SEPARATOR KIT, but that's just a guess. prettycommon problem on your vehicle. As far as the whoorling sound goes, those have upper timing chain problems. You are going to hear more of a whinning noise at about 2000 rpm's. Those chains are waranteed 5years or 60000 miles.
