All cars have blow by. Some more than others. I wanted to get the JLT catch can when I bought my car because I had a consumption problem I had a Mini. Was probably the amount of boost wearing down the rings but I know for a fact a lot was coming through the pcv system. Raptinator has gone through this several times so do a search on catch can vs. breather. I immediately installed breather filters on mine after my boss manifold install and saw a huge puddle of oil in the original manifold. Breather route works best in my opinion and it's cheaper. No more issues after 5k miles. currently have 16k.
