Timing Chain?! Help....

Ive had my Cooper s for about 6ish weeks now, i replaced my older R50 with this mainly because all i had was major problem after problem so decided enouh was enough and wanted a newer faster more reliable model... WELL..

After a few days i noticed it sounded like a diesel starting up? the would disapear after a few minutes & when driving it felt like it was loosing power in short bouts when i put my foot down (juddering), was quite scary when on the motorway, thought it was going to die on the outside lane!

Ive done abit of research on here and MiniTorque and it all points to the timing chain so im panicking my garage is going to do diagnostics on tuesday but does this sound familiar to anyone? I'm hoping to find out the damage before i have to fork out for it.

I'm a bit peeved as i was hoping the unreliablity was over My partner told me not to get another mini but i didnt listen

I'm sorry it's the timing chain or timing chain guides to be precise.
there is a chain tensioner that is meant to keep up the slack in the chain, it stops holding as much tension, the chain starts vibrating and bouncing around in the engine next to these plastic rails that guide the chain and apply the tension. these guides start to crack and in some cases break apart.
the best thing to do is have the cam cover removed, have the chain and guides inspected from the top for cracking or damage and if the guides are ok, fit a new chain tensioner and hope that they aren't too damaged, otherwise all the chain, guides and a few other parts need replacing.
I'd definately try the chain tensioner first, maybe even without removing the cam cover. replace it and if the noise goes you can maybe get away with it

If you or your Partner are handy with tools, have a look at the tensioner as it may be stuck.

Have a look on YouTube for "Replace MINI Cooper Timing Chain Tensioner - Gen 1 R50-R52-R53 2002 2006" by Mod Mini !

Its a simple process and if you haven't done further damage you could save yourself some labour costs.
