On no, if you ask TDI POWER the VR6 chains NEVER fail. :rolleyes:

Yeah, I know exactly what you mean. When those things start making noise they slap and rattle all over the place and beat the crap out of the covers. I do not think the BHW can ever get that bad and still run. :p

O - TDI POWER, believe me chain can fail! On my VR6 it happened at around 240K which is quite a lot for a car anyways. I agree not many people keep their cars that long or drive them that much. I'd love to change my car every year, but unfortunately this isn't in line with finances :). I consider myself lucky with the VR6 btw. What happened is tensioner failed and chain slipped couple of teeth on the cam of bank 1 (front). Problem happened at startup - obviously - tensioner had no enough strenght to push on the chain due to chain rail COMPLETELY worn off! Result was 3 bent exhaust valves (thanks God, they didn't fall inside the cylinders!) It took alot of work to fix, but nothing major was broken (especially cylinder head and engine block).

Chain is definitely not a life time item, at least not for people who tend to drive cars more than the waranteed kilometres, which describes many of us.

Sorry for the offtopic thing but I wanted to shout it out!

So the real root cause question: does VW have a chain problem, or a tensioner problem? :D

I guess it doesn't matter, the result is the same, and curable by gears.

But I do wonder because timing belts also have tensioners.

Timing belts do not have a series of endless metal links being drug across a plastic surface. It is common sense that chains' tensioners simply have a finite service life. It is just that the BHW's setup is shortened due to the fact that it is spinning at double crank speed and has a very small build for the task at hand.

And it simply does not matter how much, how often, what type of oil used, etc. They will still eventually wear down the plastic parts and get so much slack they either get noisy or simply no longer hold enough tension and jump.

You should see some of the deep grooves we find in all kinds of chain guides and tensioner shoes on all types of cars. Shoot some of the Nissans will wear them so thin they shatter and wedge in between the cam sprockets. Some of the Toyotas will wear so bad that the chain starts wearing through the aluminum timing cover into the coolant passages that go between the engine block and water pump! :eek:

I bought a pair of Tannoy Eyris DC1 speakers in Toronto last Christmas, to complete my 5-channel streo system. I shipped by Canada Post, and got it here in 2 weeks. No custom and brokerage charge etc.

All the best

Depends on how Canada Post (CP) is feeling that day..... they are supposed to process taxes and duties on behalf of Canada Customs, so do not be surprised if Duty is charged. Now the big savings is that CP charges a brokerage processing fee of only $5.00 on a package, as opposed to the shocking variable amount that UPS, FedEx and other Couriers charge...

You Tube Videos of a before and after BS to gear conversion
 
Here is a trio of you tubes I have created to document my Passat's Oil Pump Chain Noise. Engine was warm after a 20 mile trip. Same Camera, same fps, etc. We now have three videos. One at 44k, one at 56k and one post-op at 57k.

This was taken with 44,444 on the clock:

This is a post-op recording June 2009 at 57,000 of my Passat after Oilhammer

Wow! Such an improvement. That wee chain musta been flapping around pretty loose for that amount of noise...

Route 66 June 21st, 2009 20:44

Soumds like a new engine.

PlaneCrazy June 22nd, 2009 07:55

Mine definitely sounds like the second of the three youtubes, at 111,000 miles.

I am wondering why does the plastic cover look like vobbling like that (slowly). I guess it is video camera effect due to the FPS count and the normal vibration of the engine. Looks funny though! :)

Leica, do you mind doing similar recordings with the lid closed, near the cetre lower area of the nose? This is where I can clearly hear my chain gliding (grinding) over the chain guides. I know it is too late to take the "pre-surgery" recording, but the post surgery would be nice.

leobg June 23rd, 2009 06:01

On a second/third hearing, I can clearly notice the same chain noise on pre-upgrade video as mine does, yours is lauder though! This sound is definitely missing on post-upgrade - wow!

I had the camera on the lowest quality setting to not make the file monster sized. I too noticed the wobling effect, but after I closely looked full screen at the others, they too do this. So I am not too annoyed with it.
