Technical Louder When Hot .......

[Galilio_Mad]

hello everyone

i have a small problem, just wanna someone to help

the thing is, when i first start the car from cold it sounds excellent
as the engine worms up, the noise starts to get louder and louder
when the car reaches normal operating temp which is 80-90
the engine noise starts to seem like grinding noise with a discreet whistle sometimes

what could this be ?

thanx in advance

anyone ?

Well it sounds like a bearing, something that is revolving, maybe on the timing belt side side.

Thanx JONTI
i was starting to lose hope that anyone would reply
also i think you`re right, i know for sure that it`s not the timing belt tensioner bearing as it`s new, also my water pump is like 2 months old
i`ll check the alternator, PAS pump and the alternator tensioner bearing ...

thanx again
