Your car is equipped with hydraulic lifters or in this case followers you have one or more of these that have failed causing to much clearance between the camshaft lobe and the valve and this causes the noise, you will need to replace the lifters...good luck

Rattling noise sportage 2008

Sorry for the late reply but, no, it is not related to a loose heat shield. It is a louder rattling sound more like a loose bearing vibrating inside either the transmission or the clutch assembly. Only between 1600 and 1900 rpm. and it is not present under ou over these rpm. The rattle desappear when I lock the 4X4. Dealer is out of solution!!

My Holden Barina (2001) makes a rattling noise emitting from the right hand side of the engine. It gets louder when I accelerate. Yesterday I lost all power after only driving it for 1km. The oil level is...

Check all of your belts and pullies. Sometimes it helps to remove the belts and turn the pullies by hand. Also run the engine without the belts for a few seconds. If the noise is still there, then it is most likely timing components rattling.

Rattle noise when I let go of the accelerator. The faster I go and then slow down, the louder the rattle noise

Have a look at the shrouds around your exhaust system, they are prone to shaking loose and rattle on over run.
Try giving your exhaust a bang ( with your hand when it is cold) and see if it causes the noise . Follow the noise.
Sometimes the baffles fall off inside the muffler and rattle around inside too.
Happy hunting!!

Engine rattling noise when reving above 2599 RPM's

sounds like crank noise....very serious...

but less serious to fix then to fix after it goes.


if could also be the vanos, variable valve timing. but at 2500 i'd say crank, especially if it has that rattle tone. that sound is a wearing connecting rod bearing. when it goes, the engine basically blows up and the insides try to escape through the engine wall...that destroys the bottom end, when that happens, stuff sometimes also goes up into the head, that destroys the top end.

then you would need a long block.

BTW: stop revying it above 2500. you need an engine job....seriously maybe cheaper to get a replacement engine from the junk yard.

Screeching sound at the back of engine at the top of head

Check all the bolts and fastenings for the heat shrouds around the exhaust manifold to make sure they are there (and firm). If you can undo them without snapping them, take the shrouds off to check for gravel trapped in that area. It could also be a failing cat converter, but a lot less likely. My next step would be to remove the rocker cover and have a look......
