Thought i had joined the broken crank club but NO!

So bit of an update ... no pics but im going to call it as the wrong bolt supplied.. there is no markings on the bolt at all.. it has done 63400ks and 7.5 yrs on that bolt..

So today managed to drop sump and found the cam chain and a few other small metal bits, so that was a relief..
Timed the crank which done my head in as there are several holes in the flywheel and doing it on my own was a pain but only 1 of the holes does line up with the locking tool the rest are about 1/2 hole out..

Had no joy trying to get the broken bolt out , so will just fit new oil pump cause knowing my luck its proberly been damaged by the bolt breaking.

Not sure how much it really means, but all the valves measure the same height from the collett to the top of the valve stem..
Next job is to pull the other manifold and check for damage.. and try and find all the 8mm and 10mm sockets i have dropped and havent managed to find..

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..

Cheers Bulletman

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

Ok thanks Eric.. i could proberly do 1 side at the moment as it has no cams in it but the othere side is a bit trickier as it has the fuel pump sprocket on the other end and its looking like a mission to try and remove that cam... thankfully I havent found any broken roller rockers under that cam .. but should be able to rotate enough to close those valves
