This engine had a tear down inspection before putting it in the car. The noise is not coming from the crank, or the piece. They are saying, connecting rod is making a noise, I don't know how they can come to that conclusion, according to the mechanic, the noise has amplified, according to me, the intensity of the noise isn't constant, sometimes more and sometimes less, but no vibration or missing or anything of the sort. The mechanic advised not to run the vehicle as it may cause more damage.
What would be your thoughts if a soft overhaul is considered, using these 3 assemblies to make one fully functional one?
