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.

SOURCE: oil consumption, rattle, engine noise

Check under the hood and inspect the valve cover gasket. If it's bad it would explain why you don't see any leaks on the ground because it's probably burning off on the manifold. This ticking you're hearing is a lack of lubrication to the rocker arms. Apart from the valve cover gasket, you should get under the car and inspect the oil pan and oil filter for seepage. Best of luck on your problem.

My Audi A4 2009 makes a rattling noise on cold starts which resolves in less than 30 seconds. Dealer says its an air pump. This doesn't seem correct. The noise comes from the front of the care. Does not...


READ THIS (happy ending so far...):
audi a4 2L turbo quattro, manual transmission with 98,000 KM. Perfect conditions, no oil leaks whatsoever.

Left the car off for two weeks in very cold weather (-10C down to -25C). When I restarted, it started immediately but with heavy rattling noise due to camshaft adjuster not getting enough oil pressure. After 3 minutes of warming up (outside temp.: -12C) at very low rpm (below 2,000rpm), I start moving the car. Still hearing heavy rattle noise. As soon as I pass 2,000 rpm, I get a scary red warning, low oil pressure. Turn off the engine immediately. In 1 minute, I re-start the car and the engine lights check ok, so I drive in first gear super slow (1,200rpm) hearing the same rattling noise. After another minute, finally the noise all the sudden disappears and the car starts running just fine.

Called Audi dealer and they told me that in extreme weather conditions, I should warm the engine for 10-15 minutes if necessary before start moving.
Take away: luckily, I didn't screw up the engine since I was using it at extremely low rpm (easy to do with clutch and manual transmission) until the oil reached full pressure. I am pretty sure now that the problem was leaving the car off for such a long time in freezing weather. All the oil flows back to the bottom, and when I restarted it, the cold oil with high viscosity took a long time to reach all the parts of the engine, specially the camshaft adjusters that are actuated by using oil pressure. Next day, the car started at -9C perfectly without making any noise (as usual). Basically, the longer you leave your audi in cold weather, the longer you might hear the rattling noise until the oil reach full pressure inside the engine. My car took 6 minutes to fix it after couple of weeks in cold weather. This makes sense to me; in fact, in the past I only heard the rattling noise after leaving the car off for a couple of days in the winter.
So far, this has had an happy ending....

The 2.2 or 2200 four cylinder engine is bad for lifter rattle after the mileage gets up there, timing gears are also noisy in them.. I have had good luck using full synthetic oil, I would buy an engine oil flush kit with the next oil change and then use synthetic, If this noise isnt consistant with engine speed, then i would look at pumps and pulleys on the fron of the motor, sometimes AC pump clutches get squeeky and often rattle when disingaged, try turning the AC or defroster on and of to test for a change in the noise.

4.0l's are notorious for valve rattle on cold start-up. There is really nothing you can do to make it go away short of completely replacing the valve train in the top end, and that isn't a permanent fix. It's is an top end oiling issue from the factory. Just don't race your engine on cold start-up until the rattle stops.

The rattle in the transmission sounds to me to be more of a loose dust shield/heat shield around the transmission or exhaust than a mechanical issue.

04 Endeavor rattling noise


I had the same problem! I crawled underneath the car and discovered that a heat shield on the exhaust header pipe was corroded and rattling against the exhaust pipe. (Before the muffler)
I removed the portion and clamps and solved the problem. Give it a try.
