ok on my civic i have cold air intake and the breather hose for the oil that comes from the intake seems to be working backwards. the hose is transparent blue so i can see that oil has been going through it into my intake and i think this is wrong but i would like a second 3rd, or maybe forth opinion on it. i had to take off the intake to work on something and when i looked inside the intake tubing there was oil.....wtf? what is causing this and is it suppose to suck oil into the intake?

thanks

No, its not supposed to be in there...not really anyway.
Just go to autoshits or pepboys, whatever, and pick up a tiny ricer filter for the valve cover. That will solve your problem and stop the blowby

 

yep. they don't call it a crankcase breather hose for nothin'. The stock intake does the same thing, it's just black so you can't see it.

 

should i put one on the air intake also? how much oil could this be causing me to burn?

 

Some boosted ppl run catch cans because boost increases crankcase pressure... and thus, increases the blow-by. If you have worn out rings or bad valve stem seals, it can get out of hand.

 

On a healthy car, it's negligible. On a sick car, it still won't really hurt you. Your car was designed to burn off oil vapors for emissions reasons.

 

all good to know info.....thanks

 

If oil is dripping out of the intake or your breather hose when you remove it... then there IS a problem.

 

its not dripping and there isnt alot(maybe 2-4 times more than you pull out on your dipstick if even that) of oil in the intake tubing when i removed it but ive had the car since september 04 and the intake and hoses were new but now that hose is black. i have put on about 10-15,000 miles on it and the hose is already black. the reason it bothered me was if there is that small amount when the car isnt running then how much is running through when im driving at 75mph or even 90

 

not as much as I thought, clearly
