Hi guys... I was hoping someone could assist in my problem solving.
I have a 2009 Jeep Patriot 2.0crd. I recently snapped my timing belt which caused all my valves and rocker arms to bend.
While I was getting this damaged repaired, I decided to take the turbo in to get reconditioned as I have been hearing that dreaded 'turbo siren' for quite some time and was told that the turbo was unbalanced. They ended up replacing the core as well.
After some time at the mechanics, I got my Jeep back and noticed a big loss in power and boost.
After numerous complains to the mechanic I decided to take it back to the place that installed a uni-chip a few years back so they could remap the chip.
They were unable to remap it and had to disconnect the chip as the turbo boost was not to the factory standard (as when I originally took it there).
The original specs were 105.7KW and 305Nm with the turbo boosting at around 2000rpm.
The new spec readings are 98KW and 298Nm with turbo boosting at 3000rpm.
They told me that it was definitely something to do with the turbo.
I took it back to the turbo specialists and they told me that it was the rod setting that was set a fraction off resulting in the veins ending up to close together. I got the turbo removed and took back to them yesterday to reset the rod ( I think its the actuator rod).
I picked my car up from the mechanic today and it doesnt
seems like there is much difference (boosting at around 2800rpm now).

I do not know what else could be wrong. Could it be anything to do with the replacement of the valves and rocker arms or even the machined head? I asked if he had done compression test after repairing the head but he told me that there was no need for that unless the pistons had to be replaced as well.
I don't know much about mechanics and by the looks of it no one wants to take the blame.
When I rev the car under no load, it seems like the air is restricted compared to a few years ago.. I am also getting almost no boost in 1st gear.

If anyone has any ideas as to what the problem could be, I would really appreciate any advice.

Hi, thanks for the reply .. all the con rods were bent so he replaced those as well. He keeps telling me that there is only a need for compression tests if the engine is overhauled. Sounds like he is trying to get away with a sloppy job.
I also chatted to the guy at the turbo place and asked him if he is sure that the core is the correct one. He replied by telling me that only one core fits in a certain turbo so it is definitely the correct one.
Im not sure who is telling the truth or lying between the two of them.
So a certain core may fit on the turbo but it may not be the correct one?

The damage that is caused to these engines when a cambelt goes REQUIRES a rebuild. Your mechanic is blowing smoke up your a s s. You need a new guy

As for the turbo, there are several Garrett turbos in exactly the same housing and the cartridges are interchangeable.
