Needing a bit of help here guys, Doing a pre MOT check as well as an oil change, i fond this sitting in the bottom of the engine tray when i took it off. Its a snapped shouldered stud with a nut on the end of it with a torx head.

I cant see where it has come from, however i have noticed the Freelander sounding a bit rattly a bit like when the air con compressor was making a strange noise due to low refrigerant.

Any ideas?

Thermostat bolt?

That's an exhaust manifold to head stud. There is also a tubular spacer that goes with it.
It's broken off, so presumably it has been over tightened during work on the vehicle. Hyundai Ioniq 5 Ultimate. The family car.

ok thankyou , as long as know which area to start looking at ill see if i can retrieve the rest of the stud.

Ive just also had the same happen with my Discovery TD5, one of the studs to the manifold snapped off

ahh 6K046 studs and 9A432 tube

Don't wait too long, probably just a bolt-up job but if there's exhaust leaking and it etches the head you might need to replace that, or pull it for machine work.

Used to be an all too common issue on Td5 Discovery and presumably Defenders which were known to warp their exhaust manifolds and shear studs especially if they were tuned. Mine needed 2 manifolds replacing and was cured with an uprated bolt and spacer kit.
They made a high pitched screech on heavy acceleration sounding like a slipping belt. Has yours started making any unusual noises recently? Landrover - turning owners into mechanics since 1948

No the Discovery hasnt started making any noises as of yet, , i wish i had a garage where i could get it in and strip the head off, but winters coming up so will have to wait until after winter if i can
