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

mid June 23 350kms east of Balladonia WA had almost same symptoms. 2013 Disco4 TDV6 regularly serviced and well maintained and less than 150K. Ended up getting trucked back home (about$12,000.00 after RAA subsidy). Landrover mechanic lifting body off chassis this week, he thinks maybe crankshaft but wants to investigate further.
I've read previously that JLR have acknowledged problem with crankshaft failure due to assembly problems? Has anyone had any support from JLR in getting their broken crankshaft issue sorted?

needs a class action for the 3.0 and some of the 2.7s as well. The number of them is well above what could be expected.

So I guess the lesson for the rest of us is, if you don’t know what grade bolt has been fitted remove the timing belt cover and check.

If in doubt, change it out!

(Preferably with a genuine bolt).

So todays findings so far

Battled 2 stuck injectors which finally came out... thats a whole other thread
Pulled passenger side inlet manifold and found 2 broken roller rockers but also 5 broken bolts that hold the cam caps on and all bar the fuel pump end cap was loose... guess with broken bolts they will be loose.
Also found the cam chain has jumped on the teeth as the cams didnt line up with the 2 diffent colour links on the chain.
Valves that i have measured are all the same height as each other and also the other side so make of that what you will..

Will give it a clean and look for more damage /broken bits and continue on ..

Oh the joy ... cheers Bulletman

Do a leak down test through the glow plug holes. That'll tell you if the internals survived

Ok i will need to look that 1 up.. i havent removed the glow plugs but ive come this far so worth looking into..

It's basically a compression test in reverse, you add air to the cylinder and it'll tell you how much it can hold. Easier to go through glow plug then injector as there is usually an adaptor for that in the kit

I have an injector leak down test kit you can borrow if needed. The check through the glow plug holes will tell you if all valves are seated correctly
