Hi guys- going to adjust the inlet cam tomorrow to bring my torsion value down a bit from its current -2.9 as its always had a slight 'judder' at idle when warm.

Which is the exhaust cam and which is the inlet?
Obviously our engines are mounted long ways so its a bit for confusing for my little brain



Car drives fine- loads of low down power with a fuel consumption figure of 0.4 l/h- averages 43 mpg @ 36 mph average speed. But has always had this judder at idle.
Not planning on adjusting the exhaust cam. so is the inlet cam the one to the right or left as you look from the front of the car?
