Power loss

Good afternoon friends,
I wanted to know if you can help me, I have an Isuzu KB 92 4x4 gasoline, but it turns out that I have changed several pieces such as: cluts, gasoline pump, gasoline filter, injector cleaning and even made it overalls, and yet it is very asshole to the point that the first one is exhausted.

Hello Carlos when a car presents this type of failure, the first thing you should do is check the compressions, if you are well you can continue reviewing the rest of the components

Are you sure is the engine ???? medile the compression. And he heats the machine ??? Maybe if it is not in the engine it can be in the Embreague.

Good morning my estimates,
and the mechanic medium with compression and it is in 170, he tells me that these cars by nature are assholes, but I do not know what to think, if that will be true, as I say that the engine is 2600 and being a pic-up as it will be so asshole if they are made to load them and this even though it does not carry the march is exhausted and the worst thing is that it has just been done.

Hello partner,
you would see that the mechanic measured the understanding and was in 170, but it just overwhelmed, and the cluts changed it a for months.}
