Hi everyone,
I have a 2008 Mini Cooper S, R56, N14. The car idles rough and there is the tell tale rattle.

i not being a mechanic in any way, shape or form have had to spend a small fortune on tools as I did not even have the basics such as trolley or socket set.

I have bought an FAI FCK118VVT timing chain kit which includes everything including the can shaft sprockets but oddly not a replacement crank shaft bolt which is a must replace.

any way, to the point of my post. Is the any way and if so how can I ensure timing chain preload when torquing both camshaft bolts without the timing chain preload tool and required low torque wrench.

massive thanks to you all.

 

Procedures for changing and checking chain are located here --- https://www.newtis.info/tisv2/a/en/

I highly recommend you either spend another small fortune or beg, borrow, steal the proper tools for timing.

As a last resort, and not recommended, use the actual tensioner instead of the tool. You can always verify the adjustment by removing all tools, manually rotate the engine (CW) a few rotations, reinstall tools and measure tool-head clearance with a feeler gauge, as described in the newtis procedures. You might want to have more than one set of TTY bolts on hand if not using proper tools.

 

Actually I gave it some consideration after posting my question and came to the conclusion I have spent so much on tools and so much on parts that it didn't make sense to cut the last corner so I ordered a Laser Pre-Tensioning Tool and a 0.05-5nm Torque Driver.

 

Worst case, you can always post the tools for sale when you are done. Helps a little bit. Good luck!

 

i've bought them now so i'll keep them.
can't afford the oil pump chain or the water pump and belt so i'm sure they'll come in handy a few more times.

loads of thanks for you reply

 

BMW AG closed the newtis.info ...any chance you direct me to available procedures for check and changing the timing chain? 2010 R56
Thanks!!!

 

I have a DVD with all the TIS info up to about 2010 model year Mini's, and definitely N12 / N14 engines. Unfortunately it requires a Windows XP or 2000 PC to access it. PM me for more info.

 

I too am interested in the timing chain info. I have a 2009 MC base model with 104xxx and I believe a N12. I worry about having problems with the timing.
