as above I always put a oil catch tank on my cars but where abouts does it go on a 1999uk 2000

Pretty much anywhere it fits.

The crank and Cam breather systems run at different pressures. May need two cans to avoid forcing pressure back up one system. The crank systems also uses a pcv which can be bypassed. All gets a bit technical and confusing from there for me.@stants recently did a set up on the crank system.

You got any pictures of what pipes go where
