in the morning when i warm up the car, after stepping on the gas pedal and let go, i heard some rattling noise from the engine somewhere
it only happens in the morning first start, or when the engine's cold, after driving for awhile, the noise is not noticable
i took it one shop and the mechanic said the noise's from the tension bearings, he noticed that i had new drive belt, he asked if i recently changed the timing belt, i said yes and tension bearings as well, he suggested me to go back to the shop who changed the tension bearings for me
i did that, but didn't tell the mechanic what i was told, i just told him that i heard noise, and he told me that it's the pump which's already old that doesn't pump enough oil up, that's why it only happens when the engine's first start or when engine's cold
who should i listen to?
