If the cam timing is out, the engine will definately run rough.
Get it checked ASAP. You don’t want the chains to skip a tooth, to be honest, I’d stop using the car in the meantime. Whilst the replacement of the guides is not a cheap job, it’s considerably cheaper than a new engine.

Thanks, I'll give the garage a call about it now. Any experience on how much it costs for guides?

Cheers

Not sure about costs, there are a few snippets of info on the internet that a search will bring up for you with some stories of other owners that have had the work done.

Thanks. I've contacted the garage, hopefully will get it in soon. Surprised it doesn't raise any faults.

My Jag sometimes sounds like a bag of nails on idle. (pinking).

I disconnect the air meter, turn the ignition on for 5 seconds. Turn it off. Reconnect air meter lead.

Once restarted it sounds perfect (as the fuel trim has been reset)

Which engine has your Jag got Andy? Seems chain guides are a known issue on the 5.0 and can be f-series expensive to fix. Usually throws up faults though. Garage can't look at the car until late next week, so I'm stranded for now as I really don't want the engine to croak.

An old 4.0 Supercharged V8

Timing Chains, Google Land Rover LTB00474 should find some info.

NAS but should be same I would think, not very good copy I'm afraid. PM me an e-mail address and can send better copy if you want it.

Nice one Col. Looks like this might be the issue after some more googling. Been an interesting 3 months of ownership so far. Hopefully once I get this nailed it'll behave. I'll chase the garage tomorrow and mention the TSB.

Thanks for the help!

Have a look at this, will give a insight to engine takes a couple of mins. to download.

My VIN starts with 'SA' according to the IID tool so I suppose that TSB doesn't apply to me. Symptoms seem similar tho. Noise + misfires. Nothing back from garage yet, might try another one.

They all start SA I think, the bit you need is the two letters preceding the last Six digits i.e. AA215623 - CA759577. If you go into the on-board menu to service where you check oil level, you can also display Vin. No.

Ah - in that case my VIN is in that range. I've forwarded the TSB to the garage as well. Thanks again Col - you are a fountain of knowledge.

No I'm just a sad sod with nothing better to do.

Booked in for the end of the month. Had a warning that it could be super-expensive, not looking forward to the bill. Not much else I can do with it though, so I'll just look forward to having it healthy again!

Cheers for all the input.
