Clio 172
Strange one. So my brothers got a 197. He bought it from a dealer without me taking a look witg him, he's kind of a spare of the moment guy.
The deal was they done a cambelt and water pump, I know it's been done as the parts are in the boot.
Any way it makes this noise once warm if not driven hard. The noise I initially suspected was a tight belt, I had him take it back to the garage to check as I was reluctant to start digging holes in someone else's work and they came back all good.
He lost faith and asked me to take a look, stripped it down and timing is bang on and the tension of the belt is perfect both with the tensioner and a digital belt tension meter.
I reset all the parameters from cold in the ecu and boom, the noise starts, even louder, didn't even need to drive it. Pick the revs up as it gets quieter.
If you rev it to the red line the noise disappears almost completely.
With a stethoscope I've traced the noise to the depahsher area but after inspection reluctant to think it's failed as it's not the normal noise you'd expect.
My only other thoughts are lack of oil pressure through the vvt solenoid gauze or wrong oil.
I just wanted to know if anyone has had a similar noise or if its a characteristic of these engines before I go ahead and waste time diagnosing any further.
Cheers for any help in advance
