Noise coming from the engine, Knocking sound or Piston slap? Help, idk Options

[naxxal]

Hello everyone,

I have purchased 2 weeks ago a used 1995 St manual with 167,000 miles for $900.00 from my buddy, the condition of the car is great, except because friend of mine wasnt very cautious and carefull of his car, slacking on little problems causign others, anyways, my problem is this.

At idling i hear knocking sound coming from the engine, listening closer i would think something sounds like there is a little problem.

1. Valve knocking
2. Piston slaping
3. Engine mount
4. Or i do not know

a. Did some research, id there and engine knock than it needs to get adjusted, HOW?

b. If there is a piston slap, check which one by disconnecting a spark plus wire from each cylinder at a time untill knocking stops to get the right one, if so, Than WHAT?

c. Could it be an engine mount? Is so, than if i fill it with polytherine, from experience it will eliminate wheel hop but make higher vibrations, but will it mount better? sounds silly when someone may fill in broken engine mount to fix it, is it not?

If it something else let me know, please, i am slowelly repairing and tuning it up, so let me know, cause i want it to work well, thanks.
