99' EM1-oil burning smell
So Im kinda stumped on this one.
99' civic SI
115k mi
no mods
28 mpg avg= normal
Here is everything I looked over and confirmed.
Oil burning smell *
-only at idle- smell through air vents when set on outside air(of course)
-only at operating temp. no smell when cold (of course)
-no fluids burning on exhaust pipe-anywhere
-engine does not have any oil leaks anywhere. (since I have owned the car I have put a rear main seal/lower pan gasket.)
-No other leaks of any other fluids-coolant/brake fluid/pwr steering.
-*engine is not burning oil- I change the oil every 3000mi- dip stick shows full when I hit 3000miles for the past 6 oil changes.
- **NO smoke out of the tail pipe at all. In any conditions- idle/cold start/operating temp/WOT
- no DTC's at all.
-Engine is completely bone stock.
- I know the previous owner and he did every maintenance at Honda(per service book-older guy in his 50's)
-Only thing I can think of and have not checked yet is PCV valve sticking.The PCV has never been change to my knowledge and rubber seals(on PCV/baffle box) are hard as a rock.
(@ idle in theory = highest vacuum- sucking oil fumes<--oil smell? I know PCV goes into the IM and fumes cant escape into atmosphere. But IDK what else to check out.
RonJ@HT any suggestions?? anyone? thanks

A new PCV is cheap, and it wouldn't hurt you to replace it anyway. I would also closely inspect the length of your exhaust for any signs of cracks or damage.
