My catch can just arrived yesterday, I know most of you are thinking why didn't I get one earlier, right? Well I ask myself that very same question. Anyway, before installing it, took the jeep to a friends ****** asked them to take off the intake manifold and have have it cleaned (with petrol and air blowing everything away ). First the intake was soaked with oil, so if anyone who hasn't put a catch can and was wondering if he should clean up the intake manifold before doing that, YES you should.
Noticeable change in drivability, much smoother now. I think I'm going to do this every few months regardless.
I'm sorry I couldn't take pics of the dirty intake, but I'm sure you could imagine how it would look like having 33000 kilos (20505 miles) of abuse on it.
