Volvo Repair Questions? Ask a Mechanic for Answers ASAP
is the noise related to engine speed or road speed ?
is it effected by cornering ?
Ok then this could be an issue with the clutch release bearing?
if the noise changes when you push the pedal down then this backs this up
typically a release bearing will be noisy for several thousand miles before really needing to be replaced
you'll notice it becoming harder to change gear if the bearing starts to bind up
the fix is to remove the gearbox and replace the bearing with a new part
there's a small timing chain in the cylinder head that drives the exhaust cam, so the main timing drive is by a rubber toothed belt on the front of the engine and at the other end ( gearbox end) there's a short chain in the head
if you remove the oil filler cap and listen as the engine is 'revved' up you may hear a 'tinkling' noise
if so then this would indicate a loose timing chain
if the engine oil is old then a drain/ flush and new filter with fresh 5W30 may help as its not unknown for the chain tensioner to become sticky with old oil deposits
