I have it 2 years new belt and LR Oil Pump fitted 60,000 km ago 2007 315000kms.
Really love the car but don't want to risk this again.
Called three breakers so far and no engines available (not even sure I want to fix /install one)
At the moment I would like to know the cause an likely damage.
Thanks

I would suspect cam stopped, due to perhaps chain issues, or seized cam, which then broke the pulley.
I would take the cam cover/inlet manifold off & investigate.
My guess is it's terminal.

This seems to be a common problem i have seen lots of simular photos.
I havent investigated any to find the cause but i know you are going to have a least a number of bent valves, you would have to remove the heads to see if any pistons are damaged if they are ok you may get away with fitting a couple of second hand heads.Andrew

Seen a few of these now. Cams weren't seized
Almost like metal fatigue of the pulley. But then that doesn't explain why some have done 300k miles without issueMy D3 Build Thread

As my engine is stripped down Ihave just replaced both of my wheels. I did wonder if historically POs might have relied on the timing pin tools to lock the engine when removing the bottom crank front bolt and this could of affected them? Either way for what new ones cost I didn't think long about that change decision. I hope you get sorted out soon👍D3, D2 and RRS owner 😱

Thanks
Just spotted the fatigue on two of the pulley legs
Anyone know if I can take the head off without removing engine?

I think you may have hit it on the head there people just relying on the pin to undo the crank , it takes a bit of grunt to undo the crank pulley .

Hi
I've the cam cover off, some cam bolts sheared.
can I remove the cam shafts without removing the vacuum pump.

Hi, same thing happened to our 2010 RRS, damaged valves etc, currently reviewing options and gathering info on historical camshaft pulley metal fatigue failures.

No, the pump is cam driven so has to be removed first. It might be worth considering head removal?
These sprockets seem to be weakening with age or perhaps incorrect belt tension. Had one like this last year, same sprocket.yµ (idµ - eAµ) ψ=mψ

Would have to be some kind of moron to do that, the majority use the flywheel locking pin or at the least a tool that holds the crank pulley before undoing that bolt.
The bolts on the pulleys arent that high a torque so i'd just put it down to fatigue.
