If your CAI uses an oiled filter that is the likely culprit.
I do not have a catch can. I have seen a small number of posts that showed small amounts of oil caught. Most reports have indicated that nothing was collected.Has anyone had experience with catch cans actually catching fluids?
All I’ve ever read about was how they’re installed... but no one has been able to retrieve unwanted fluids.
I’m used to oil separators from my pre-ecotec days and it’s my understanding that since our PCV‘s are locked inside the intake manifold, that there will always be oil seepage.
Anyone have more (and/or positive) experience with this?
Catch can experience on a V8 is not going to translate to an EcoTec 4.I have CCan on my Trans Am and yes it certainly does trap oil. I don't have one on Sky V8 (yet) but will very soon. There are a lot of models out there. Some are better than others, and any decent one is better than none (but make sure it has some kind of filtering element).
I also have run a K&N filter on my TA since nearly the day I bought it and never ever had I seen oil from the filter on my MAF (over 50k miles). If you do, you put way too much oil on the filter to start.
