Problem with bearings of the engine 2.0 16V GT

Hello to all,
I have a one special question about FEDOHC 1st Gen 626 GT 1988 2.0 16V.
My friend has this car like me but longer time.
He has little bit problem with bearing of his engine.
In a some idle speed the car starts twitch. But It can be recognized only after longer driving I mean more km.
He told me that he saw when some guy drive to some garage that when it start twitch it also shows black cloud from exhaust.
So logically that means that engine didn't burn up a fuel.
He tried to give the car to Mazda just for fun but they told him like always it is ok only whole engine is in the shi...
But this is their normal bearings they will switch whole engine for a lot of money and it will do the same stuff like before...
So we decided for the easier solution to try switch some parts from my car to his car and after week we will see what it will be doing...
When we thought about it we decided that we will try switch igniters, cables and distributer and on the end injectors...

I just asking you If someone from you also had this problem...?
All answers are really apprecciated.

Thanks a lot.

strange issue. or strange description.

i have a hard time believing the main bearings are cooked.

if the rod bearings were cooked, it would make a loud knock as the pistons hit the head.

you are right about black smoke = fuel. this can be because one cylinder isnt firing at all. perhaps low compression on one? or some other uneven problem. this could also cause some feelings in the car.
