    Hey everyone this afternoon I felt like checking out my intake valves for carbon and soot buildup as I hand scrubbed them 10,000 miles ago at 50k (you can find these images on page 2). I was pretty surprised to see a moderate amount of carbon build up on the right most valves and quite a bit of...

    Hallo, I've got a 2.0 and I want to install a oil catch can to prevent the carbon build up. Do I also need to block off EGR or not ? Which hose do I need for the PCV system ? 3/8 , AN-6 or something else ? Did someone of you this mod ? Regards, Felix

    Having done a decent amount of research it makes alot of sense to install a catch can IMO.

    Being direct injection engines, SkyActiv's are inherently at risk to carbon deposits on the intake valves. Has anybody installed an oil catch canister, and if so, how much oil has it collected? What are your thoughts on whether it's worth installing? They're cheap so it's more of a time...

    So, I have heard all of these things about carbon build up on direct injection engines, there have been some write ups at Miata.net specifically on the 2.0L. So, I have just less than 2000 miles on a 2016 Mazda3 2.5L and decided that I was going to put one in. James Baroner racing.com sold me...
