Our mirror image oil breather / oil separator tank for the Escort and Sierra Cosworth.
This tank simply bolts to the left hand strut tower as a mirror image of the water header tank.
It's purpose is to extract the oil from the air/oil vapour which high powered cosworths are renowned for creating. The oil is returned to the sump, whilst the clean air breathes to atmosphere.
Not only does this save on oil consumption but also keeps the engine bay free from messy oil vapour
This configuration is particularly good for left hand drive Cosworths.
