Title: 24V Tensinoner Failure
Post by: GotMojo on May 19, 2015, 11:12:45 am

I didn't record the sound this makes when the engine is running but was able to replicate it manually.  If you hear this tak-tak-tak noise, your tensioner is failing.  Change it!

Here is the difference between the failed tensioner and a new one (dry).

Thanks. I'll see what it takes to make this mod.

This is an awesome and very helpful video that you made. Really lets people compare how something should be performing -- which can be difficult when you take on a second hand van (and you don't yet realize that some noises aren't normal).

Comparative analysis!

This is for a 12 valve (http://uploads.tapatalk-cdn.com/20160507/236def69e8a1dfe1693d48a23f02e133.jpg) it is a manual tensioner.
