Just the guide is probably making the noise. So either a new guide or a new chain. I would start with guide first, unless chain looks loose or cruddy

SOURCE: mechanic replaced timing chain but rattling noise

Replacing the timing chain is done around 100,000 miles, but can last as long as 200,000.
Sounds like something may be on its way out, and a rattle does indicate a chain. Not all oil pumps use chains...many use gears to spin the oil.
Most people know when it needs replacement when they are calling for a tow truck.
It could be your water pump as well. It is hard to tell where the sound comes from sometimes. A stethescope may help pin-point the sound to the part.
Good Luck!

The Oil Pump is behind the Crankshaft Sprocket which does involve the Timing Chain.
You will have to remove the: Timing Chain Cover, Timing Chain and Crankshaft Sprocket to gain access.

Let me know if this helped...

The warranty company is wrong, the oil pump is in the bottom of the engine, inside the oil pan. The timing chain is behind a cover on the front of the engine. An extra hour to r&r the timng chain is reasonable. My question would be, "why in the world does my 4 year old $40,000 truck need a new oil pump and timing chain already.

There is sound in the chain and the oil is not going to the tintioner when engine is hot


What year?? If 2003 or earlier, then you need to replace the timing chain guides/tensioners. BUT you said of no oil going there (do you have oil pressure light on in your dashboard??? If so, then you have oil pressure issue, meaning likely oil pump failure), that usually a bad sign of engine failure soon.

Many 2.0 TDI engines show excess chain noise and wear anywhere from 50,000-100,000+ miles. Cars have broken the chains/tensioner as low as 65,000 miles. This is just a range of cars that have been reported, diagnosed, and repaired. The actual statistics on dealer repairs or failures is unknown and I've heard cars over 100,000 miles that, in my opinion as a non mechanic (most mechanics wouldn't recognize this sound and problem either), aren't noisy. From what has been reported, noticeable noise/chain-tensioner wear/greater risk of breaking is around 60,000-150,000 miles. Your case may vary. The most obvious symptom is a rattling loose noise from the oil pan. Unless you listen to a Passat TDI with a tight chain and one with a loose chain, it's hard to describe the difference other than rattling chain noise.
The reason the gear drive oil pump modification was started is because a few mechanics who specialize in TDI have seen many worn oil pump chains/sprockets/tensioners. There will always be a few defective parts that come off the assembly line and all mechanical components like chains wear out sooner or later, but in my opinion, the failure rate is abnormal considering the number of Passat TDI sold versus the number of reported oil pump failures. This does not necessarily mean that every or even most Passat TDI will have this problem, just that the reported failure rate is high enough to consider this part a design failure. Nobody, not even VW-Audi knows the average time between failure for these parts and the percentage of cars that will have this problem, but they changed this design and if you want to not have this specific failure, the only sure way is to swap to the geared module.

Can you tell me how to replace timing chain on a 1966 impala


The best way is to pull the motor out. The timing chain cover needs to come off of the front of the motor (behind the water pump) and this can be done with the motor in the car. The problem comes when you try to put the cover back on. There is a seal that fits in a groove on the bottom of the timing cover. The seal will not let the cover go back into place without damaging the seal. The oil pan needs to be dropped down and then the timing cover goes into place. The oil pan goes on after the timing cover is in place. Any other way will result in premature failure of the timing cover to oil pan seal. If you have enough room under the car and can remove the oil pan, that will work also. I hope this helps.

Does a 2003 cavalier have timing belt or chain?


Most overhead valve engines have a belt. You need to get your engine size, make, model and year and call your local parts house and they can tell you this for sure.
