hey guys, i've been noticing an obvious smell of oil from my car lately. it happens after my car is properly warmed up and tends to be more obvious when driven under harder load, more boost and warmer temperatures.
Anyway, i had what appeared to be an oil leak so i thought i had solved the problem. I cleaned it up and it still smelled but no leak. i conclued this must have been a spill from a previous time. Anyway, after a bit of "sniffing around" i noticed the smell was most definitely coming from the intake. I've read that it's common to have oil in the intake from blow by. I haven't noticed any oil consumption since my last oil change, it's been full for probably around 2000kms, but it's hard to tell, maybe it has gone down a BIT but if it has, it's not much. i'm using mobil 1 5w30 and my car has 145k KMS on it (90k miles). stage 1 tune.
could this just simply be blow by? should i use a heavier oil perhaps? maybe a catch can or AOS wouldn't be a bad idea? any advice or thoughts are appreciated.
