Timing chain replacement

[mojo]

Hi.

As you now I own 2010 journey 2.4l.  and I have done alot of maintenance procedures to it, new oil pan, transmission pan and filter, new injectors, new ignition coils, new VVT, new spark plugs, vavle gasket, intake gasket, cam sensors, crank sensors, flushed power steering fluid, front and rear control arms and pushing and suspension, new throttle body, new map sensor. 

Had a major issue of cylinder one miss fire for more than a month, it was reaolved finally by erasing adaptive settings and doing a transmission relearn. Was a big headache at the time. Three years later i add 40000 km to odometer, now reaching 330000km. The car gives a cam/ cranksensor error even with new sensors. The Car when driving from a stop some times just cant shift easlynfrom 1st to 2nd unless I ease the gas pedel/ throttle. 

I believe the timing chaing is loose/ off even though it feels stiff and not stretched. But it is the main culprit l.

 

As the car value is not that much, and the cost of timing chain replacement at a shop might exceed its value, how hard it can be to replace the timing chain by my self (i uave no issue fixing anything as most of the car repairs were done by me). Do I need to replace the cam gears and the crank gear. 

 

One thing we noticed two years ago,  the Drive Belt came off/ snapped, went to the autopart shop and got an exact replacement, but it didn't fit. No matter how much i stretched the tensioner it was small and short. Went back with both the old and new one to the dealers and they gave the exact one and told me i was doing it wrong. It didn't fit. Called a mechanic he came and reied both for 2 hours and couldn't get it on.  I towed the car to a shop, they tried the OEM ones and none fit, they told.me they had to get a one inch bigger belt to fit and they dont understand whtas going on with car. 

 

I dont want to pay a lot of money to fix the car as its not worth that much except for me. I want to fix it and use for a couple of month the pass it for free to someone who wants a car and cant afford it.

 

Thanx

What codes are coming up. If the chain is stretched and worn it will set codes. Get it scanned first.

 

If the drive belt (it's actually called a surpentine belt) was a challenge; don't go near a timing chain replacement. Much more difficult, several hours work for trained mechanic with the proper tools.

 

Cam and crank sensors usually have a relearn procedure. Not necessarily plug and play, especially if not oem factory parts.

Hi.

The cide is "P0017 Crankshaft/Camshaft Timing Misalignment - Bank 1 Sensor 2"

 

All sensors are OEM. and i have an obd bidirectional scanner, and in special functions i couldn't find the relearn procedure. Is there a special way.

 

The belt was a challenge when it was tight, not now. And i dont  realy want to do the timing chain, i have had enough unless there is no other option.

 

Thanks.

I did the relearn, i remembered i did that long time ago. Followed the instructions and that didn't help. The car shuts off at an intersection. Then if i press the pedal hard it will trigure limb mode.

 

I went through my reset. And found that the crank sensor is the only one not OEM Mopar, its NAPA. Could it be causing issues, or the time chain.

Was it running properly for a few months with the new napa crank sensor ? The cam sensors also have a relearn procedure that matters. The vvt solenoids have mesh on them that can get plugged up; another potential problem. Especially exhaust vvt solenoid.

Hi.

I think the napa one worked for a couple of weeks 1 or 2 then the car just went crazy abut cam sensor bank 1, replaced with mopar and went away. The VVT solenoid were replaced 3 years ago, but I'll take them out and clean them. 

The relearn procedure is it the same. The scan tool says I need to drive fro 10km to 60km the coast to 10km and. Repeat. 

 

Thanks.
