Febi OM642 timing chain tensioner defective? Part 1

[@jaguar7051]

The old type of tensioner can suck oil when you do as on video For that reason gets improved with the ball valve with spring. The old type tensioner has a ball valve without the spring that can work two ways.

Hi, what is your opinion on a tensioner manufacturer? Genuine MB is made in Romania, worth $172. INA and Febi are two alternatives, both made in Germany, $70 and $90, respectively. Is there a knowledge by chance who is the OE supplier? Thanks.

Bonjour, et merci pour la vidéo. Avec le nouveau tendeur. Vous avez résolu le problème?est-ce bon la chaîne fait du bruit quand vous démarrez?

Hello yesturday just for a little my engine will die I wanted to replace a tensioner cause sometemis it makes noise at cold atart, when I changed it it startes really high rattles, i removed again and it looks like the new tensioner its not stertched its the same as is came, my question is why the new tensioner its not streched do I need to do something before install?

[@glasser2819]

of course junk tensioner! They had to engineer a way to wear out additional items such as... camshaft journals phaser lock pin and timing chain itself by lack of pressure caused by tensioner leaking any remaining pressure on the passenger side of v6/v8 engines. It's amazing how quickly parts that used to last forever turn into junk these days... too many stupid repairs help recycle recent cars early 🤗

You have to change the oil .....sometimes.

Have always had issues with Febi tensioners.

thanks for the video after removing the old tensioner when you hold it next to the new one is the length the same or is the old one longer?

[@skantha75]

Old and new both were same size in length.

New improved tensioner not filled with oil for easy insert and screwing in.

Exactly

I have same issue. I purchased brand new chain tensioner, preventative..... Car was worse than before. Everyone say I need new chain...... 1week later I take out new tensioner to check operation........... No hold pressure!!!!!! Now I know why clatter clatter clatter. Replaced with old tensioner. Now smoother but I think my chain is now stretched because eof driving with faulty tensioner

[@bryant2919]

What brand tensioner was the replacement?

[@launchbenz2242]

The design of the tensioner isn't to suck oil by itself. A constant oil pressure will feed the tensioner while it's on the engine. The tensioner will not act like a pump,my friend. The other it's already charged with oil. It may be defective but that's not the way how tenisioner works. The real oil pressure pushed into tensioner it's quite high when engine is running.

I agreed thats why I created part 2 of this video. Pressure build up when I did the test submerged in oil.
