Just been recovered to garage

Sat outside as closed and checked the fuses all are fine seem corroded
So I scraped the terminals and put back in correct sockets

Cleared codes and still no joy

ABS light now comes on dash

Also waking away noticed the right headlight not working

Done all I can now I think time to leave it to the mechanic

Will update and thanks for your time as always appreciated greatly

Hey all

Cars at garage no clue when it can even be looked at and am really struggling to get about with no wheels it’s killing me!

Is there anything I can do to the car while it’s sat on public road outside garage please?

Voltage readings on the sensor wiring maybe?

Or buy a sensor and plug it in separate?

Clutching at straws here but am desperate to get on road

If you have checked everything as previously suggested, then there's little else you can do without the aid of a workshop and comprehensive diagnostics.

It's a difficult spot to be in when you rely so heavily on a vehicle.

Just called garage out of desperation and it seems they forgot to update me that the crank has snapped Sad

Do we know what’s the best option from here please?

Is it worth getting a new engine in at this point?

Thanks

Very frustrating - just called the garage and they said they haven’t even looked at it yet so they don’t know.
5 minutes before and the owner has just told me it had been checked and is snapped but he’s away on holiday

Proper stressful!

Does anybody know if the raised oil level on the dipstick (on level ground)
indicates crank is in fact snapped or could this be normal if it’s something else?

I’m trying to figure out what’s most likely as I’m in limbo with it

Also the day before I used hill descent on a steep hill and there was a lot of grinding - does this sound like the engine or was the grinding normal? As it did sound bad

Sorry to hear that really bad news.
Start looking for the following used cars for their engines.
If nothing else you can use as a run around

Jaguar S type 2.7
Jaguar XJ6 2.7
jaguar XF


I would expect the crank to have some float at the front under the cover.

I wonder if they are guessing. You checked the starter turns the camshaft after all.
And I would expect some oil leakage?

One said it’s been diagnosed but the workshop said it hasn’t been. Pointless chasing as one’s on holiday and ones at hospital.

Spoke to another local workshop and they said try start it with brake cleaner in the air filter to ensure it’s not the fuel belt? I did check the fuel valve there was diesel coming out but it wasn’t squirting loads just like a trickle

What do you mean by those cars? Get one that’s a runaround and then swap the engine to my disco?

Just looked online can see supply and fit for 3k on eBay with 6 month warranty

What do you mean some float on the cam shaft? Like wiggle up and down if I push it through the oil cap?

Defo no oil leak. But level is raised.

It’s a mare mate as I’m in the middle of a mortgage and I can’t use any credit to get another car as it could mess the purchase up so I’m desperate at this point just searching for options. Will be a week before the garage can confirm. Other local garage said mid feb to even look at it.

I get the feeling the garage will be more interested in it being potential scrap to break down so want to be ready to ask how it can be proven as snapped crank I guess? And look to get a price to rebuild maybe instead of body off and new engine? Or would labour outweigh the value of the car?

maybe a v8 engine and auto box out in or would that be way too expensive and a silly question?

I'm surprised to hear the diagnosis of a snapped crank given you filmed the D/S cam shafts turning!

If it is snapped, your best option is a replacement engine from those Pete K suggested. You'd have to weigh up the costs though assuming you find one. (car + partial engine rebuild, new belts, oil pump, bolts, seals, etc, etc + labour!).

A recon engine is an absolute nono in my book as there are too many cowboys in that game, so don't even think about going that route!

To help confirm the crank diagnosis, you could try turning the crank pulley bolt whilst the car is in a forward gear. Put the car in third gear, then release the hand brake and turn off the ign. Using a torque wrench, turn the crank pulley clockwise, if the car moves forward the crank can't be broken?

Be careful though, and make sure the car is safely secured or can't roll away.

I’m going to go where it’s parked Thursday and spray brake cleaner in the inlet and try start it, also drain some oil from the sump plug and see if there’s any metal in. Do these sound like good ideas?

I can’t get it recovered home now to remove everything and try the crank pulley with a breaker bar. I was going to try that.

Will mention the cam is moving again when they call

Thanks

Let’s just assume for now they haven’t diagnosed it. If the car hasn’t moved from where you left it it’s a safe bet.

You could take the bottom engine cover off. But even that seams a waste of time if the fan and front belts move when starter actuated.

It won’t be the fuel belt as you have a fault code saying crank.

A petrol v8 or recon engine from eBay are a no.

I wouldn’t bother messing with the oil filter

Ok thanks

Do you mean if the fan belt moves when cranking that it indicates the crank is ok?

I was thinking drain the sump oil not the filter - in case there was any metal in there perhaps

Could do with compiling evidence that it’s not the crank where possible

Yeah.

So you know where the starter is. The gearbox end.
The drives the rear of the crank.

The front end of the crank is where the oil pump seal is. You know where that is too!

So if the starter is making everything move correctly at the front of the engine (fan, belt, cam in oil filler hole ) then the crank should be ok.

I’ll check Thursday crank it and watch the fan belt soo if it moves

I know the cam inside spun but just to make sure haha

Wont hold my breath but I’ll be relieved if the belt does move at least it’s not a new car needed
