Hello everyone, I'm Steve from Ireland . I'm new to forums so be gentle

I have a 2007 Rangerover sport 2.7 diesel.

I was towing a caravan and the engine just stalled on me as I was exited some traffic lights.

I cranked it a couple times but no start. And hasn't started since.

On the diagnostics it came up with a P0341 camshaft sensor fault.

I've replaced the camshaft sensor (pain of a job

) but no joy.

Diagnostics still stating the same code referring to (camshaft segment period is too short)

I'm not a mechanic, but I am able to work out most issues. Unfortunately my limited knowledge has stalled with this one

I'd appreciate any pointers anyone can offer as this is my only vehicle and budget is low....

Thank you in advance.

Steve

While cranking the engine, can you see the camshaft turning through the oil filler cap?
Does the crank pulley turn?
Hopefully you are aware of this engines failure points..

Hi Mark, thanks a million for replying.
Yes camshaft and crankshaft turn.

I am aware that these engines are known for the crankshaft failing/braking.

Is it possible there is damage even though all are turning?

The next step and there are two options.
The first is a hack, you can spray a little break cleaner Into the air I take and see if the motor starts. If the motor turns it's not a skipped timing belt and could be something else. If it doesn't fire up it could point to a jumped belt which means there could already be damage.
The second is to remove the timing cover and check to see if the engine will line up with the timing marks. If not it's jumped a tooth or so. Possible damage depending on how many teeth it's missed.

I checked the timing and it had slipped, I replaced the timing belt and re-timed the engine. It's turning over way better now with no bad noises from the engine.
However it will not start, it's trying to but not. There is black smoke coming from both exhausts as I crank it is this a sign of anything?

All engine fault codes are now clear with no new ones....

Any help would be appreciated, I really need my car

How had the timing slipped? tensioner/belt etc.
How did you lock/tome the crankshaft?

Interference engine so anything less than perfect could be bad news.

Black smoke suggests it's getting fuel. Personally, I would do a compression test because if the timing slipped, there may be valve damage. You could try a squirt of Easy Start to see if it will fire.

Hi, not sure why the timing slipped. The belt had slight damage on the edge but no teeth missing. Tensioner was at the correct position.

I have the correct timing tools, I took out the starter and locked the crank with the crank tool and I positioned the cams at 5 and 7 o'clock with the pins.

Just locking it at the crank is not enough for this engine I suggest you look at LRTIME on the tube for more info about correct timing on this engine.
The main concern is how and why the timing jumped. I'm afraid that sort of failure usually ends in terminal engine failure. Scrap car.

Are you sure the tensioner mount was okay and not cracked? this was a big failure point a few years ago, and the oil pump casting has been superseded a few times to strengthen it.
Damage on the edge of the cambelt would suggest to me that the belt is being run off the edge of the pullies.

Sadly LRs of this age with engine faults are pretty much scrap value.
