Change of oil and found metallic spring etc inside - need your advise.

[andronikos916]

Now after reading this I have 1-2 more things to mention:

I bought this car 4weks ago - around 670miles , 2 days after the slave cylinder died (previous owner never bleed the fluids).
I replaced the slave cylinder... I was driving the car for 2 weeks and I decided to change oil/sparks etc so I have peace of mind - and I found these pieces on my oil...

So now I am around 900miles still breaking the engine. (actually I am not driving it anymore).

Before the oil change this is my story: - driving between 2000 - 4000rpm. But there where some times that I tried to push couple of gears and I noticed that:

1) When I press full throttle, after 4000rpm was not operating well, like the carburetors are not well tuned (not sure how you say that in English -hope you understand what I mean). If I press 3/4 of throttle then it goes well (of course not using all the power but at least smooth) up-to 5200rpm. I have past experience with 2-stroke motrcycle engines so I thought that maybe I need to push it more so it "cleans". I do not want to do that since I am still "trying" to break in the engine.

2) So I feel that it is impossible to accelerate fast and all the way up to 6000rpm. (even if I do not care about the "break in" - simply the engine does not allow me)

At the beginning I though it was spark plugs so I change them. Then I thought that the previous owner was using wrong oil. I change that as well. Yesterday I convinced myself that it is just a carburetor that needs to be tuned.

Now I really do not know what it is...If this pressure oil and the tiny parts I found on my oil filter are connected with the acceleration issues etc...If something serious is happening...

Thanx - Andronikos,
