Well done another 2000km and just inspected catch can. I got 18ml from catch can. But also had oil in the outlet of the catch can and all the way down the outlet hose. I cleaned all oil from the outlet and outlet hose last inspection 2000km ago.
Just inspected our Rangers intake after 120,000kms of the Provent 200 being fitted. Thought I would run a can of Liqui Moly Decarb through it whilst Im there. Intake all the way up to the EGR was spotless and dry. Minimal soot build up around the EGR and the intake below. Minimal disassembly and just one can through it since I already bought it. Very happy with the Provent as its the first time I have inspected after fitting and it is doing what it should do.
