Hi all,

I just bought a 2007 model Range Rover L322 TDV8 3.6 Vogue with 240,000 km on the clock. According to the seller, the only issue was a minor battery drain... that turned out to be a lie.

After 100km, I’ve started hearing a very strange noise — it sounds like a bird chirping or twittering. It only happens when the car is under load going uphill or when I’m hard on the throttle.

I'm not sure what it is — my guess is a boost leak or, more likely, an exhaust manifold/header leak. I’ve recorded a short video of the sound https://youtube.com/shorts/8tPW3vFjnP8?feature=share. Has anyone here experienced the same issue or can point me in the right direction?

Thanks in advance!

For anyone getting the same noise, this turned out to be a warped exhaust manifold on bank A (warped 0.5 mm cylinder 1-3 seems straight, leaking mainly on cylinder 4 and maybe a little on 1 but there was also a leaking injector return pipe just above, so the discoloration may be from that). No broken strut bolts. The repair isn’t that hard—just really cramped. Without a lift, it’s probably not a fun job to do. Parts are relatively cheap (I got a new manifold for €130, plus €50–70 for gaskets, new bolts/nuts, etc.).
