Alfa romeo 147 engine knocking help!
Hi, i am new here. So i bought alfa romeo 147 2003/1 1.9JTD 103kw, So there knocking sound coming. So, there was old oil, i changed (dirty ). Also in service i just checked crankshaft, there smalls scratches u can fill with finger nail, so i buyed new bearing (i dont know in english how that means) putted everything. Also checked top of engine there everything was shine. Also the oil system cleaned and the belt changed (i find there a problem that was jumped 1 teeth
) and there now smaller knocking sound, but still knocking when it warms little bit u can hear that, when press throttle it knock faster with engine speed, when release throttle on small revs it start knock louder. Also find some metal pins in the oil of the bot ( i think people who had car, the belt maybe dropped and damaged lifter bearings, becouse they like new when checked). So what to do more i cant find the problem, i just putted ceramic oil thretment but need to ride first 1000km to start work that. The knocking sound coming from bottom of engine..
