Hi. New here so i don’t know if i can paste a link to a fb post. Really frustrated after 8 months of trouble with my 2015 Hyundai.
All cars leak some oil in the intake through PCV. In time it creates all sorts of problems, from burning on valves’ stems and making them move harder and create lifter noises and lifters work harder and foaming oil to trapping dust and turning into a sludge to interfering with swirl flaps like in my case.
Pulling oil from the intake with a modified mat pump seem to alleviate the problem, instantly. I recently installed a catch can that will probably take care of it in the future. In the mean time i don’t know how to remove all oil from intake so i can get rid of the faintest noise still present. https://www.facebook.com/george.ion.7505/posts/1088471284689053
