R56 Cooper S timing tensioner how to
Discussion
Morning all. Replacing the tensioner on my partners N18 late 2010 Cooper S tomorrow.
I have had the car health checked and while there is no chain stretch, it always sounds like a diesel and on occasion sounds like a bag of bolts. The new tensioner was revised in 2013, so it has an older revision in, and was only £16 from the dealer. That I was amazed at, but I bet they sell a few!
So, I am taking off the cam cover to check for uppper guide wear. I am not removing the sump to check for broken guides as you have to remove the exhaust and reseal with sealant. I will be changing the oil and filter.
So I know how to change the tensioner, but do you have any hints or tips. Air box and IC pipes will be removed. But do you have to prime the tensioner? Or just spin the car over a few times with the coil off?

Thought the n18 tensioner didn't have any issues or revisions as it was a far superior chain set compare to the previous n14, but when I replaced my n14 tensioner, I removed the pipework around the area of the tensioner for access, slackened off and removed the old, and popped the new one in, was tight as I recall due to the position the engine was stopped at, would have been easier at tdc I guess, but wasn't bothered at the time.
So, that was nice and easy. Air box, and IC pipes off. Tensioner out, new one in. Different part numbers. The old one was 8mm shorter!
It has made the engine sound better, but you can still hear the chain up to 3k. Took the head off and all guides are present. We will see how it goes but for peace of mind it may still get all chains and guides done. Lohen only charge £600 and it may be worth it for peace of mind.
The car is still on the Mini TLC and went in 2 months ago for a full service. The air box was full of leaves and dirt and the filter was a filthy no name affair. Not happy about that.
