Frequently asked questions

What is the LLH500100 crankcase breather hose for?
The LLH500100 connects the rocker cover breather outlet to the intake manifold plenum on V8 EFI petrol engines. It carries blow-by gases from the rocker cover back into the intake to be re-burned, helping keep crankcase pressure correctly regulated.
Which vehicles does this V8 breather hose fit?
It fits the 4.0L V8 EFI Defender (1987-2006), Discovery 1 (1989-1998, North American NAS spec only), Range Rover Classic and Range Rover P38 (4.0L and 4.6L V8 EFI). Confirm your engine and market spec against the fitment notes before ordering.
Why does the crankcase breather hose fail?
V8 breather hoses harden, split or collapse with age, heat and constant oil exposure. A failed hose can cause a rough idle, oil leaks or a whistling vacuum leak. Replacing it restores correct closed crankcase ventilation.
