timing Chain

Oh holy BS I'm sorry buddy I wouldn't think that would be the case in the Gen too

 

The timing chain on the 1NZ engine can go for $500,000 mi or it can fail the first week out on the road but that's not likely The one NZ is a very proven engine no kidding You're on the right track maybe the spark plugs Make sure your coils are good and you have good fire for the ignition.

 

how many km on her?

 

12v, tyres, belt, water pump, wheel bearings, cv joints, bulbs, discs and pads, wiper blades, combo meter, brake actuator, battery modules...

 

Until the motor blows up for some other reason? I would expect the rings to lock up and oil usage to go through the roof long before the timing chain fails. Assuming of course that the car never runs low on oil. Heck, even then it would probably throw a rod before the chain went.

It's a CHAIN, not a BELT. Timing belts (rubber) do need to be replaced (at least on interference engines), timing chains (steel), not so much.

 

IF the engine is maintained correctly, then the timing chain lasts "the life of the engine". You shouldn't need to replace it unless there is abnormal wear. (my 2006 has almost 200k miles and no indication that there are any mechanical problems).

Typical routine maintenance items are: oil & all filters, engine and inverter coolant, transmission fluid, brake fluid, spark plugs and pcv valve, clean throttle body. Inspect water pump belt and idler, brakes, suspension, test the 12V battery, cooling system parts, exhaust system, tires, lights, etc.

The OE inverter coolant pump lasts around 100k.
I don't know if the fuel filter is serviceable (North American spec Gen2 is not)

at 240k miles my 2006 Prius throw a code for timing correlation which means the timing chain is stretched. It is perhaps the easiest and cheapest timing chain replacement I ever did.

You only change it when it throws a code or making a noise (tensioner maybe)

If you're doing proper maintenance such as oil change often this shouldn't be an issue and it could last a lifetime.

You say it was "easy and cheap" to replace the timing chain, but I was just given an estimate of $3K to do that on my 2004 Prius. Am I being scammed?

 

Do you have codes for this or something Why are you needing a timing chain someone's telling you there's a tick or??

 

And you're up here in Southeast USA yeah that's extremely high oh my god you could have a whole replacement engine for less than that so something isn't making good sense If you're willing to spend that just change out the engine there are a lot of low mile engines around in this model to get by low mile I mean like 150,000 that's just barely broke in unless it's been seriously abused usually the oil condition and the smell will give you some idea just overall look but I would be surprised if you're Southern cars leading a timing chain but it's possible.

 

yes you are being scammed big time. The timing kit costs less than $100 (cloyes) in RockAuto, but then the shop could add the gaskets and labor for $2500+ is absurd.
if you have a code P0016 then a timing chain is needed otherwise correct diagnosis is needed (it's not a common issue in gen2) This is the easiest timing chain replacement job on the planet requiring no special tools.

 

Yes, the code is P0016, and they say that the cam shaft and crank shaft position sensors are fine.

 

My car has 172K miles so not much more than those low-mileage engines you speak of. There is no smell.

 

I didn't take it to the shop that quoted me $3K, since they couldn't look at it for more than a week.

The problem I'm having is it dying when stopped at red lights, then is difficult to turn off (takes maybe 45 sec to turn it off) but when I turn it on again I can drive fairly normally, until I have to stop again.

I cleared the codes so the mechanic that has it now is going to drive it tomorrow to see what codes are generated. Apparently you have to drive it to generate codes.

I don't think the timing chain is causing the stalling.

 

the timing chain could stretch if oil changes are not done properly. How was this maintained? when you say "dying" you mean the dashboard just blacks out? or the car just turns off. You need a proper scan tool to scan for codes, majority of the obd scanner only scans the ECM, you need the one that scans all the computers (Autel maxi AP2000)

 

definitely they are working since you won't that get code if they aren't.

 

No, the dashboard didn't black out, but I press on the gas and the car doesn't move. Maybe loss of power is more accurate than "stall." I admit I haven't been very diligent with oil changes.
