A question only experts can answer

[Ted]

Dear All,

I challenge you if there is somebody who can answer to my question. Autolanka make a very good servide but I am highly doubtful whether I have got a clear answer to my question which I have been submitting weeks ago. My question is what is the damage if a small ( 3mm width, 5mm length and 4mm depth) was one of my pistons of my car and I had run with it around 30 kms?  Visible damages were 5 small scars on piston with around 2mm depths. Ever after removal there is a little noise coming from the engine. No visible and tangible worn signs of the cylinder.

 

1) Has my piston damaged?

2) Has my crankshaft damaged?

3) or any other ?

 

Only experts can answer this. I hope such an expert is in Sri Lanka.

My Dear Friends,

 

I did notice recently in this forum is that ppl are giving comments not to the point. Earlier this trend was not in the forum. If you cannot give a comment to the point and write stories here it is a waste of time. Please I still did not find satisfactory answer..
