SOURCE: engine noise at cold start-up.

Sounds like your oil pump inside the engine is not pumping oil fast enough when you start your vehicle its common problem for mitsubishi motors my car does the same thing.

good luck

SOURCE: Rattling Coming from Engine At low RPM (stopped) and when accl.

If this sounds like a tin can rattle it is likely a loose heat shield on top of the catalytic converter. They come loose after time and corrosion take their toll.

SOURCE: Noisy engine idle and stutter at low or high speed

I had the same problem (X-type 2.0d 2004). The stutter was cured on mine by getting the ECU fashed with the latest firmware. This is a known problem and the update does cure it (£28), I didn't bother with all the tests the garage wanted to.
The noisey engine at idle is the alternator belt. It resonates at idle and causes the noise, There is a modified bottom pulley, tensioner and belt kit, but it is rather expensive ~£200 plus fitting (around 4 hours labour). Mondeo's have the same problem but that kit doesn't fit the Jag.
Hope this helps

SOURCE: 98 Ford Explorer engine/exhaust noise

When catalytic converters go bad, the porcelain matrix inside comes loose and is noisy.
But you can just unbolt it, break up the loose chunks, pour out the pieces, and it will run better than ever.
If you don't pass the next emissions test, then replace it.

But it could just be the heat shield rattling instead.
Take the shield off first, to see if it goes away.

I would check exhaust system for loose heat shields or bracket.

The oil pressure is low at idle and rises with higher engine revs. Oil levels are ok, new oil approx 2000kms ago. Was a slight noise at one stage in the engine but went away after engine's revs in


It sounds as if the clearance that the bearings normally run in have been surpassed and need to be replaced. Higher engine revs will supply extra oil which will overcome any small discrepencies but constant running at this stage will result in faster degradation of all engine components concerned resulting in a more expensive repair. Shes basically worn out.

Growling engine noise only at idle. Cam area


Take all of the belts off for a short run at idle. If the sound goes away it is pulley related, spin each pulley and listen for bearing noise, also check for play at this time.

If the noise does not go away when the motor is driving no accessories you have a more serious problem.

If the rattling changes with the revs of the engine, it might be that the valve compensators are either worn or not getting enough lubrication. 20V engines have quite small oil passages travelling to the head. They tend to clog up with gunk if the oil change is not frequent enough.

Sounds like the viscosity of your oil is not high enough for the mileage. My van has a loud valve rattle when it is low on oil or is in need of an oil change. I use I higher viscosity oil and a bottle of lucas oil stablelizer and it quites right up. This may not be the case for you. You need to isolate the noise. By isolating the noise it will give you a better idea of whats making the noise. Try using a mechanics stethoscope and find where the noise is coming from. It might just be time for your mechanic to overhaul your engine.
