Thread: Thought i had joined the broken crank club but NO!

Sorry to hear this.

Even though you note unlikely to be the oil pump, if the timing belt tensioner mount bolt has been reused, or is not genuine, they are known to snap the bolt after the oil pump has been replaced.

I have also seen pictures of a failed TDV6 where bizarrely one of the timing belt pulleys actually failed - snapped all the spokes on the main pulley on one of the heads.

Do hope it is a simpler problem.

I did the oil pump and the timing belt myself and a new bolt was used.. i ordered it as a full kit so i can only assume it was the correct bolt.. but in todays world anything is possible i guess..

I got a new hpfp fitted and belt done by the indy in Darwin as i was working away when i started to have the dreaded fuel faulting so im assuming he replaced the belt using good quality parts..

So just some advanced warning - I won’t say much more as I truly hope it is not one of the factors in this situation.

The supplier who sells those full OEM kits does not include genuine timing belt pulley bolts. They would need to be sourced from LR.

Of course this is all just speculation at this point. Let’s see what you find.

By the way - I believe you can inspect the timing belt from a hole viewed from underneath.

If it has failed, the belt would be loose on the bottom drive pulley so you may be able to see this without removing the timing belt cover.

Yep more likely to be oil pump if not updated or cam chain, run your hand down the timing cover on the drivers side and see if you can feel a crack.

In the original post he states it had a new updated oil pump.

Doesn't mean the tensioner or bolt hasnt failed.

This bolt fail theory is nasty as it’s a 10.9 strength bolt done up to a ridiculously low 26Nm so you’d be unlucky.
