I recently installed a GFB diverted valve and CPE intake to my fist and less than 500 miles down the road I’ve discovered oil in my intake (a fair amount). I have an X47R turbo installed and recently got a tune pushing around 27psi but I do not think that is the cause of the problem. After further inspection I noticed the oil was coming from the crankcase hose connected to the intake from the engine. I pulled my PCV catch can and didn’t notice anything in the oil from normal. I ordered a catch can for the crankcase side but I am a tad worried something is from with the purge line CPE provided and the new intake. Has anyone had any oil coming into their intake before?
When I was running a 2j intake I used to get a really oily smell and the filter (that sat up in the cowl) would get oily, really quick like within ~1500 miles of installing it.
I ditched the 2j intake partially because it made the cabin smell like oil all the time. Even after ditching the 2j and having the cowl with a hole in it the interior smelled kinda oily. Bought a good/clean cowl off ebay and it smelled a lot better.
When I recently removed my ITG intake I didn't find any evidence of oil in the intake, only with the 2j.
