Norman Scearce: Can you fix it, once it's broken completely, or will I need to replace the engine? I have an i35.
Safiloo1: I did this job on my Maxima 05, and its one hell of a job, took me 4 days and i did it alone, changed the 3 chains, main tensioner, water pump and all the guides, belts, spark plugs, valve cover gaskets, o-rings. Not to hard, just time comsuming.
Vinh Nguyen: OH man... I think I'm in the same boat :(
rothdan: To Mike s:
The primary chain tensioner wasn't providing pressure anymore, so the chain starting slapping and making and sound. Luckily I caught it early so it didn't cause any damage. We ended up replacing all the tensioners and the chain, just because you have to open the entire thing anyway to get at everything (which is why the labour costs so much). The actual parts don't cost much at all though.
mike s: which tensioner failed? the main chain or the secondary chain tensioners? mine just started making the same sounds. I replaced the main chain guides and tensioner about a year ago.
rothdan: I believe the chain on the 350 and murano is the same, but the g35 has a different part number. Same size engines, but different configuration I believe.
Raul Romero: should the tensioner of a murano and 350z, g35 be the same? i
Avason1: Stay away from nissan? That is an ignorant comment. 97 with 235,000 miles. just replaced the water pump because it was leaking a little bit. Mechanic didn't want to replace the timing chain...yes chain (not belt) because it looked great. Infinities are awesome cars dude.
Daniel Young - The Loan Doc: I just replaced the tensioner on my 2005 nissan maxima and it cured that rattle sound. the tensioner was broke and it will do it in all models of their 3.5 engines including infiniti it seems
Don17p: hey where is the timing chain located on the g's????im buying one this weekend an 06 is there anything i need to look out for???
Dalana Morse: Thanks for the fast response! :)
rothdan: I forget the exact cost, but it was well over $1000 because of the labour involved. The problem was just the tensioners (like $80 for the parts only), but since you have to take apart so much of the engine to get at it, we also replaced the timing chain just in case.
Dalana Morse: curious to know how much this repair cost you? Mine has started making the same noise. Seems to only do it when the car is cold though, but it is so loud and embarrasing!
oke1konbe: stay away from nissan huh?type in acura tl timing noise plenty of videos
CampinBush: My year is 2005 G35 Sedan. Should I start saving up for the replacement of the tensioner?
rothdan: It's got a little over 150k now. The actual tensioners were the problem that created this in the first place, not the actual chain or anything else inside. I just replaced the chain because it was already going to be open. I did notice that the new tensioners from Nissan had an updated design, so they must have found the problem and fixed it at some point. Depending on your year, you may have these in your car already.
rothdan: yeah, because no other brands have problems, oh wait...lol
CampinBush: What is the mileage on the G? Mines is 114k and I'm expecting my timing belt will need to be serviced as well.
jdmcivic817: haha... good joke... american cars suck.... import the best!!
Solumic: This is why you stay away from Nissan...
KillerZero259: whats the mileage on the G?
