c20xe snapped crank

[lukehamlyn]

would this do any damage to the rest of the engine.....i dont no if it has snapped but i think it has as there is no movement when trying to start the car....:confused:

[bazil]

check the starter first, then, ringear?

[Andy]

what makes you think the crank has snapped? You would do very well to snap a crank!

[AlexW]

Rock it in gear, if the cambelt moves, its fine, if not, then it might be snapped.

IF it has snapped, then it might have bent a few valves.

Has it not sheared the woodruff key on the belt side that the lower main pulley slides onto?

[burgo]

i will gladly put money on it that you have not snapped the crank, more likely stripped teeth off the belt or sheered the woodruff key

[bazil]

But he's saying there is no movement when trying to start, even if the belt had snapped the crank would still turn.

[bazil]

Em if the starter has gone fook all will move, personaly I'd remove the flywheel cover plate and check it's actually turning as the op has not said what's not moving, he doesn't say if the starter has been checked, missing teeth on the starter, chewed ring gear I'll sugest these but at no point suggested a snapped crack as I've never seen one or heard of one snapping.

the battery is probably flat lmfao

" click " lol

I'm looking at the starter not " popping " out and thus just giving a whirring noise and no movement, very much doubt a ring gear problem but it can happen ( brothers 2.9 4x4 sierra )


EDIT
more details here from the op's last thread

well...... it could be anything...

take plugs out , remove the timing cover & stick it in top gear & with the handbrake off, rock it back & forwards... if it all turns properly, then it can't be mechanical.

now.... if a battery is low, the starter can cause the engine to turn to a position where is doesn't normally rest, this can cause the starter gear to not engage with the ring gear, so it just goes thud. rocking back & forth will help with that. if the battery needs a proper charge, get it done.

check timing, then bump start it.

[lukehamlyn]

sorry people for this i just been told what i could off done....my cams do move...i have tried bump starting it and it doesnt work.... :S....im going to take my rocker cover off 2moz to see if i have snapped the exhaust cam as i have been told to check that too.....i no it may sound silly but im just doing what i have been told to check.....i was only doing 120 when the car cut out and it was at 2000 revs....the revs died first then it cut out...:S

[blue_peg_16v]

120 at 2000revs you must have some special gearbox

[pikey1986]

dials over-reading FTL

probably only doing 70mph lol

[General Baxter]

he could have a diesel box lol

i have seen plenty of snapped cranks especially on the hgv's. i have all so no ford ka 1L run with snapped cranks for month's. as my neighbour fixed plenty as the only run 3 main bearings

[mayhem]

c20xe's dont snap cranks or cams.

how about checking sensors...

[mowgli]

a euro (the coin we use to get shopping trolleys) says its the timing belt

[andy_mk3]

Compression test?

[Jon_nova1]

oil?
