Timing problem bent valve, tensioner?

Hi, I have a July 2005 Mini Cooper with a timing problem which is baffling me.

Something has broke or fallen off on the timing side, hit or catched the chain causing a small hole in the rocker cover and has knocked the timing out bending an inlet valve on no. 2. I've checked the rest of the valves and they're all fine although there are slight marks on the other pistons.

Does anyone have an idea what it could be? Could the crank bolt come lose?

Thanks

sounds like you'll need to visit an independent MINI specialist garage - plenty advertise here & on other forums - try calling a few nearest to you

Hi ya

Bit confused here, you have posted in the 2006 to present ( gen 2) but your car is a gen 1 r50 (2005)

with out looking it's hard to say but it sounds like one of the guide has fallen to bits
Causing lose of tension on the chain causing it to jump a tooth or two or more

It would be possible if the bolt was not tight or a incorrect crank pulley was fitted, But on the gen 1 the timing gear on the crank has a dowel pin and the timing gear during fitting is heated and crank cooled to provide a slight interference Fit once temps have stabilised. So it would have to shear that pin first
It is also possible for the camshaft timing gear to move if the bolt has lost torque and sheared the alignment pin.
Soon as you get it striped you will see
