Juke timing chain issue

I think they will figure it out. I just think it is the length and lack of "support" for the chain. Ford Mod motors do pretty good with them.

I know some GM's had the stretching issue, but what others have had issues? I commend Nissan for trying to make it right, better than being stuck with a problem. Having said that, has Nissan's quality been slipping lately? or is it just me?

Has Nissan quality ever been great? From what the limited cars that I've seen, their cars do not age as well, have normal wear parts that don't last as long as some of its competitors, etc.

When was the last time that Nissan did the right thing for its customers? Pre-cat issues with the 2.5L, Altima butterfly screw, 4L V6 timing chains, compression rod bushings on the G35s, etc.

At least Toyota/Honda have stepped up the plate and have generally extended voluntary service/replacement campaigns for the high failure parts.
 
Timing chain ain't real timing chain unless its a cam-in-block pushrod engine. A belt might be suited for some of these apps.

For anyone out there with a Juke.

Cheers


Some of us Juke owners have been aware for awhile. Good to know and to inform others though too. We been discussing the timing chain issue over here:

I had mine replaced the other week. No issues before with it but since it was under the 'campaign' I did it just in case.

I don't even know what this means. If it's a chain and it connects to the crankshaft and the camshaft, it's a timing chain No matter where the camshaft is.
 
Timing chain issues are not unprecedented at Nissan. It's KA-series engines had timing chain issues...or at least timing chain tensioner issues. My '95 Hardbody, with nearly 200k miles on the engine, would rattle like a diesel for the first few seconds after a cold start. I must say, though, it never quit, and the rest of the truck was screwed together very tight.

Looks like VW group junk.
 
That's why I personally, against the grain, prefer belts. You don't have to break any seals to replace them and the cost per mile is very low. I currently have a Nissan truck that needs a new timing chain, I had a chain tensioner break on our '04 Audi. Two of my cars have three chains each, one of which drives the water pump.

Many cars have timing chain issues, it is not like the OHV engines of the past where the chain lasts for hundreds of thousands of miles.

The current chains are like lifetime fluids...

I used to avoid belts like the plague, following the oft-parroted advice that they're too expensive, not durable, whatever. But after experiencing just how much of a non-issue they are to replace, and how access to them is designed-in (unlike with a typical chain), my avoidance of belts has almost turned around. I'm not sure I'd say that I prefer them, but I certainly don't avoid them anymore.
 
I have read about timing chain problems on the Mitsubishi Evo and Ralliart. Although they didn't completely solve the problem, they have a sensor that determines how far out the chain tensioner is. This could prevent catastrophic failure, but I have heard that when the chain and hardware need replacement, some people have to pay $1200 for repair.

Recently I have read of direct injection engines suffering timing problems. I guess fuel dilution leads to chanin wear more quickly than other factors. Since many Evo owners push the cars to the limit, they may be running pig rich fuel mixtures and cause dilution what way.

mini cooper "rattle of death"


Not sure if it's common, but the timing chain in the 2.9L Colorado I drove at my last job was rattling like crazy. Sounded like an old diesel.

Yeah timing chain stretch can be detected by VVT phase sensors, when the values go too out of range from teh crankshaft position sensor

So, how much of an issue are timing chains on these same vehicles in other markets where other grades of oil are recommended?

Then you are guaranteed to have it break unless you spend $1000 every 5 years on changing a belt.

Which is stupid easy to avoid.

I mean, it's not like, you know, come 90k/100k/105k/120k/whatever that it's NOT coming up--you knew that at mile zero. When the magical milage comes around, you start shopping for a shop. Or getting ready to do it yourself.

Or I can buy a vehicle that doesn't require me to spend asinine amounts of money on something that should be lifetime.

I have very strong feelings on timing belts.
