SOURCE: rattling noise during engine start up.. 2005 mitz galant 2.4l

Probably a heat shield. Often time the screws that hold the shields in place rust away causing the shield to rattle. After the exhaust heats up, the pipes and shield expand causing the shield to stop rattling until it cools down again later when the car has been sitting for a while. Usually you'll find shields under or around the catalytic converter and around the exhaust pipe nearest to the engine. Most folks would probably recommend you remove the shield and be done with it. That's your call. Just remember though, the shields are there for a reason. In particular, the shield under the catalytic converter is there to prevent the possibility of starting tall grass on fire in the event you had to pull off the road for example to fix a flat tire or something along those lines. It might be unlikely, but its definitely been known to happen. Let us know how it goes. Thanks.

Try checking the heat shield on your exhaust system. You should have one over the manifold and one over your cat converter under the car.

It sounds like the hydraulic lifters are bleeding down after sitting for a while... there are ball checks which are supposed to prevent this... Try using a good engine flush (a product that frees sticky lifters) and replace the oil with a good synthetic... Hope this helps...;-)

SOURCE: rattle noise from engine at start up for a few

The oil pump is not getting oil into the top of the engine quick enough on start up

I have a similar problem with a Mazda

Got over it by adding a can of STP Oil treatment to the engine

That coats the surfaces better than the standard oils and cuts down on the noise and the wear factor

I have a grinding noise in rear end of my nissan navara. When I put foot on clutch pedal noise goes away.


Your throwout bearing in your clutch is going out. More of a rattling grind.
Replace it ASAP before you end up replacing the whole clutch.
Hope this helps Mike

Sounds like something with bad bearings. Check in the area of air conditioner compressor or power steering and yes water pump.even the belt tightener will do that.

1991 Nissan 2400 pick-up, rattling sound in moter with loss of power. Oil light came on but is full of oil. what could it be?


the oil light comes on from loss of oil pressure, this can be from two things 1. your oil pump is bad abd 2. your bearings around the crankshaft are bad. If the noise is coming from the bottom of the engine, Then the bearings are bad. If the noise is at the top then this could be the distributor. the distributor drives the oil pump, there is a shaft or a pin/tongue on the bottom of the distributor. See if it is broke. Also look down the hole and see if the pump is broke. It's hard to see but you can with a good light and mirror. Just a note, If your truck has had a knock for a while(like when you start it in the morningand it goes away in a few minutes or seconds) Then the bearings are bad. It's time to rebuild or replace.
