Hello Scotty, i've recently learn about your youtube channel and boy..was i too late, wish i knew about it earlier, i've learned a ton about vehicles!!

I have recently bought a second hand Jeep Cherokee 2014, 3.2 v6 with around 140k miles on it, my naïve self got too excited about it without really knowing anything about cars, i've trusted the wrong person for sure!..(lesson learned!)

Cut long story short, the car gave me an engine light literally right when i got it, it was a cylinder misfire detected, the dealer did not fix it finding some excuses (never again there..), so went myself and the mechanic changed the spark plugs and the coils, given had quite a few miles on it and for about 200miles after that, i had no problems.

Passed the 200miles, the engine light came back on, this time the error was "p0390/u1424", camshaft position sensor ,with an implausible engine torque signal received, the car when driven in fully automatic mode would not go full power, as if the engine would not go on a higher rate and the gear would not shift correctly, luckily i could drive it back home.

To note, when i go in sequential mode, it seems like the car actually shifts ok and the engine as well works , so it seems that this issue is only in the timing of automatic-shifting (i have no other way of describing this sorry), and when in that mode, the car has very little power.

So again went to the mechanic (a different one this time) and they diagnosed the camshaft sensors in need of a change, as well they did a compression test and found that 1 of the cylinder was at 95psi (a lower compression then 100psi which is the normal psi) , they also performed a cylinder leak down test and found there is an Air leak from the intake from one of the cylinders.

they basically told me that i have to spend quite a lot of money to replace the Bank2 cylinder head, Rock arms and Lifters, as well as the camshafts.

At some point, speaking to them, they told me , might as well replace the entire Engine.. ?!

Also, they did not mention anything about the intake?.. would that even be fixed?..not sure.

So for now, I took the car out from there (after spending quite a bit of money too..and fixed nothing), since I'm looking for another opinion on this, overall is quite a lot of money, I'm not even sure if is a plausible cause of what's happening, and if is even worth it..

Any advice is very much appreciated.
