Yes, I have researched all the threads, I love my 2011 L322 5.0sc but the noise is eating me from the inside.. 112k miles.The noise is noticeable at idle/ going through a drive thru.

So far I have replaced..

Timing chain guides and all ancillary equipment.

Supercharger coupler.

High pressure fuel pumps and lifters.

It definitely isn’t a/c related.

How loud would a bad injector be? I can’t find any video/sound clips.The motor is strong and pulls hard no codes. Any of my esteemed fellow owners have any unique experience in this? I greatly appreciate your input.

You said....

Timing chain guides and all ancillary equipment.

Probably a silly question but did you change the chain...??

Faulty injectors can be pretty noisy....

Needs some diagnostics with a decent tool....  Pete

Thanks for the quick reply, the chains were replaced too. I’m at my wits end!

A good diagnostics and you should be able to tell if the injectors are poorly using live values...

You need a mechanic who knows his way around the engine...

Land Rover or Jaguar will do, the engine is a Ford unit....  Pete
