2013 Equinox died, Timing chain?

Hello all, first post to this forum.
My daughter bought a 2013 Equinox in May, used from a Subaru dealer when we bought a used subbie. (I got into subbies a while ago and really like them. Have also been a chevy guy my whole life.)
This equinox was her first car she bought on her own. Currently has 102000 miles on it 2.4l motor. It was very nice, clean, good options, and more car than the money could buy else where, so I thought it a good deal, ran perfect. No leaks no nothing. She had the oil changed a couple times and I did the break rotors recently. All was well, until last Friday 12-23-16. Coming back from shopping it lost power and she pulled to a side street and it died never to start again... She said there was no CEL, and no any warning lights except a constant low tire pressure for the same tire that we aired and it would not go out... So..... several hours later with the help of a friend and his car trailer we got it home to my garage. I looked at it yesterday. I did a code ck and it did throw the following codes, which I looked up and know basically what they mean : p0366 x2, p0106, p0011. p0341. I did a compression test and all four cylinders were ZERO, which I suspected from the sound of the car cranking it would be. So my question is what next? I have read that there are oil consumption issues, and this car was two quarts low. Not good but not enough I dont think to trash the motor, am I wrong? Also I have read about the timing chain issues.... so this is an interference engine I am thinking, right? So if the chain did break, or skipped a couple teeth, that is about all that is needed to smack the valves into the pistons and then thats all she wrote.... Is this about right? I Looked and could not find any real timing chain kits that I was sure would fit this motor,(places I shop, Advance and rarely auto zone) and never looked into valves, but with all that and any other head work that needs done... got to be around 800 bucks or so... have seen motors on Ebay for less than that delivered to my door, free... Any one ever done this? Any threads that show how it is done? (replace this motor) Can you pull the motor out the top or is it bottom only? (Also any hope of GM picking up the cost of any of this? I mean the think is basically 4 years old... lots of miles I know but...I have a '99 Suburban with 250k on it... used it to pull this car home, its still running strong... )

Thanks for any help you can give. Trying to Help my kid out here

Circuit/System Description
The camshaft position sensors each have 3 circuits consisting of an engine control module (ECM) supplied 5 V reference circuit, low reference circuit, and an output signal circuit. The camshaft position sensor is an internally magnetic biased digital output integrated circuit sensing device. The sensor detects magnetic flux changes of the teeth and slots of a 4-tooth reluctor wheel attached to the camshaft. As each reluctor wheel tooth rotates past the camshaft position sensor, the resulting change in the magnetic field is used by the sensor electronics to produce a digital output pulse. The sensor returns a digital ON/OFF DC voltage pulse of varying frequency with 4 varying width output pulses per camshaft revolution that represent an image of the camshaft reluctor wheel. The frequency of the camshaft position sensor output depends on the velocity of the camshaft. The ECM decodes the narrow and wide tooth pattern to identify camshaft position. This information is then used to determine the optimum ignition and injection points of the engine. The ECM uses the cylinder 1 exhaust camshaft position sensor to determine injector and ignition system synchronization. The intake and exhaust camshaft position sensors are also used to determine camshaft to crankshaft relationship. The ECM also uses camshaft position sensor output information to determine the camshaft relative position to the crankshaft to control camshaft phasing and limp-home operation.

* Internal ECM or sensor damage may occur if the circuit is shorted to B+.


Circuit/System Description
The manifold absolute pressure (MAP) sensor measures the pressure inside the intake manifold. Pressure in the intake manifold is affected by engine speed, throttle opening, air temperature, barometric pressure (BARO) and if equipped, turbocharger output. A diaphragm within the MAP sensor is displaced by the pressure changes that occur from the varying load and operating conditions of the engine. The sensor translates this action into electrical resistance.

The MAP sensor wiring includes 3 circuits. The engine control module (ECM) supplies a regulated 5 volts to the sensor on a 5 V reference circuit. The ECM supplies a ground on a low reference circuit. The MAP sensor provides a signal voltage to the ECM, relative to the pressure changes, on the MAP sensor signal circuit. The ECM converts the signal voltage input to a pressure value.

Under normal operation the greatest pressure that can exist in the intake manifold is at ignition ON, engine OFF, which is equal to the BARO. If equipped, a turbocharger can increase the pressure above BARO, when the vehicle is operated at wide-open throttle (WOT). The lowest manifold pressure occurs when the vehicle is idling or decelerating. The ECM monitors the MAP sensor signal for pressure outside of the normal range.

Conditions for Running the DTC
•DTCs P0107, P0108, P0111, P0112, P0113, P0114, P0116, P0117, P0118, P0119, P0128, P0335, P0336 are not set.
•The engine speed is between 575–6600 RPM.
•The engine coolant temperature (ECT) sensor is between −7 to +125°C (19.4–257°F).
•The intake air temperature (IAT) sensor is between −20 to +125°C (−4 to +257°F).
•This DTC runs continuously when the above conditions are met.
Conditions for Setting the DTC
The ECM detects that the MAP Sensor pressure is not within range of the calculated pressure that is derived from the system of models for more than 0.5 s.

Action Taken When the DTC Sets
DTC P0106 is a Type B DTC.

Conditions for Clearing the DTC
DTC P0106 is a Type B DTC.

Circuit/System Description
The camshaft position actuator system enables the engine control module (ECM) to change the timing of the camshafts while the engine is operating. The camshaft position actuator solenoid signal from the ECM is pulse width modulated (PWM). The ECM controls the camshaft position actuator solenoid duty cycle by controlling the amount of solenoid On time. The camshaft position actuator solenoid controls the advance or the retard of each camshaft.

Diagnostic Aids
•The engine oil condition has a major impact on the camshaft actuator system.
•A low oil level condition may set this DTC. The engine may require an oil change. Inquire with the customer when the last oil change was performed. You may also monitor the scan tool Engine Oil Life Remaining parameter. Advise the customer an oil change may be required.
•Inspect the engine for any recent engine mechanical repairs. An incorrectly installed camshaft, camshaft actuator, or timing chain can cause this DTC to set.

Re: 2013 Equinox died, Timing chain?

hi ,

GM # 12680750 is the fourth change up( most currant # ) timing chain kit for this engine.

GM # 12635427 is currant # for balancer shaft/ water pump chain.

GM # 12649233 is currant # for the above tensioner.

GM # 90537369 is currant # for above guide.

Engine drops out the bottom with unattaching the engine cradle and obvious connections .

Re: 2013 Equinox died, Timing chain?

GM has had problems with the 2.4L timing chains and other issues.
They extended the warranty for certain years to 10/120,000 for certain issues, I would start there.
Contact your dealer AND GM Customer Service, number is listed in below link, reply #7.

If no warranty coverage, you will need to find out exactly what parts need to be replaced.
If you plan to do the work yourself start by removing the front timing cover.
At some point someone, either the dealer or independent shop, will need to do this to give you an estimate.

Good Luck

If you have to do it yourself, there is a very good Youtube video describing the procedure if full depth.

Re: 2013 Equinox died, Timing chain?

If GM doesn't pick up the cost I would seriously consider a used motor. It might be more cost effective depending on how much damage has been done to your engine when the valves smacked the pistons.

I did a quick search and found used engines for less than $1,000 delivered. Here is an example

http://www.ebay.com/itm/2012-Chevrol...xYXss~&vxp=mtr

You should keep in mind however that an engine that was in a wrecked vehicle, while less costly, may still have issues of it's own. However, if you get a late model motor it SHOULD be OK.

Oh, also the engine and transmission come out as a unit from the bottom. Never have done it, but the sub frame gets disconnected and the body lifts off.

Lot's of luck

Re: 2013 Equinox died, Timing chain?

There are a few threads on here that discuss the oil consumption, and warranty coverage of the repair which invokes new pistons and rings.but I have not seen anything to indicate extended warranty coverage of this repair.

It doesn't appear that the special coverage for the balance chain would apply, but maybe.

http://www.gandrudpartscenter.com/20...nce-chain.html

Create and account on my.chevrolet.com with the VIN and see if there are any special warranty coverages. The trouble you will have though is documenting oil changes.
