Cams going bad is a common problem. It is why I lost interest in furthering the 3.6L platform.
Forget about oils, hardness of metals, or proper lubrication. The part that is frustrating to me is the lack of diagnostics and fail safe operations, from chrysler on the VVT and VVL.
1. The VVL...
if you look up under there, there are Square plastic pieces that look like they should have LEDs going to them and a 3 wire connector. Two of those wires actually have power of the dimmer switch.
The biggest let down I have seen on all tube doors, is the latches. If you can incorporate a true automotive style latching system on that door, I think it would be a huge selling point.
Dang Security bypass module. The jeep is fun, and capable, but there are some machines that just make life easier on a daily basis.
I had to make this call, and it is a tough one, especially when you have put your hands on most the parts, and whispered to it, to motivate it to do great things...
The shops putting LS's in the jeeps actually utilize thw JEEP ECM to run the LS with a couple sensor swaps on the engine. The goup of ECMs on your jeep have a pretty intricate security protocol. If one goes missing, It becomes pretty difficult to start and run. This is what makes putting an...
If you take the 2018-2023 from the top you can avoid cracking open the AC and transmission lines. Both of these systems is filled with stuff that is hard to get and requires a software service tool
Just for refrence, the security is not the issue. Peolple have cracked the security, the problem is it can only be flashed a hand full of times and it goes corrupt.
if it is truly knocking chances are the cams have worn flast and that metal has reN through your engine making tolerances bigger. Your oil was changed often, uou may be ok and the intake cams and high lift solenoids need changed out. I have a thread on here about it. Super easy to spot when u...
With good tuning a supercharger would make that engine a much better work horse.
Jeep all but makes this virtually impossible. I am working on a 22 at the moment, and they have made yet another roubd of foundational changes to the operating system. I am getting it figured out, bit it is so...
I would be willing to bet the pan was off due to an earlier cam failure. I would also be willing to bet the engine died due to the fact the cam or cams were not where they were suppose to be, and the cylinder pressure exploded the piston. Jeep needs to add a mass airflow sensor and a couple more...
There is a guy that posted just recently saying he replaced a bunch of stuff and still had issues, so it was directed at him.
Another thing I noticed with many of the calibrations I have looked at, they are using or copying a cam calibration position, that is generic and that could present...
If you replaced the camshaft it is good to do a cam relearn or resync. Chances are if the other cam had a problem or was worn the ECM adjust cam positioning to compensate, and now the new cam will be off
A pressure sensor on the downstream side of the VVLs would give loads of insight as to the function of this feature and if it is going south.
Diagnostics for camshaft out of range would be good also, but I imagine this is not done as it would instigate a million questions from an emissions...
No need to get riled up here. I will state what I know and some added opinion.
To clarify I have helped over 180 different people, including independent shops and dealers diagnose and fix cam failure.
I have a data trace overlay, that has been right except for two times. Both of this ended up...
