Hi mini gurus, recently rebuilt a n14b16 r55 with bad piston on 4. Reluctantly replaced timing components with factory timing chain , tensioner, and casette guides. Now less than 500 miles rattle is back, i checked if the chain stretched even though it had only less than 500 on it, it did not. I next logical part to blame is the tensioner. Its logical to change the tensioner only correct? Im planning to install an aftermarket longer tensioner. What do you guys think?
Here is a good video put out by Promini... At the end it gives you some dimensions of the new tensioner vs. the old tensioner... [ame=http://youtu.be/u6E_BBV_REs]Mini Cooper "S" Engine Noise - Rattle - YouTube[/ame]
