i built my own cai about 3 months ago and since about mid august my car has been sitting in my driveway while i've been away at school, well i went home last week and took my cai off just because i had a feeling about it and when i checked the inside it had a gooish-greasy-almostlardish substance inside it, not real thick just a thin layer on the inside.i checked the pipe to make sure it was clean before i first put it in so i know that it wasn't always there.my question is has anyone every had this happen before? if so do u know what it is from?

 

I'm gonna hafta say that is . Could ya get picks? couldn't tell ya wat it is if my life depended on it.

 

i can't get pics cause i'm at school and probably won't go back till thanksgiving the best way i can describe it is like bacon grease only darker, i don't think pics would really help because it would just look like engine grease on a towel.

 

dude! i had that in the bottom of the Y right before the TB!
but mine was Thick! looked like smelt like super think used oil to me, I took it all out.. (the size of a quarter) it never happen again, but.. i have no cule what that was from. really really weird

 

too much oil on the filter?

how many miles?

normally that happens after or at the throttle body, but not before.

 

changed the PCV valve recently?

 

hmmm here is 1 hose connected to the cai that can get oil in it....there are 2 connections of hoses onto the intake....one goes to a metal bar across the top of the engine...clean that out really good and make sure the hose on that, that connects to the cai has a wire brush in it

 

i sprayed some TB cleaner into it about 3 months ago.. after that it sounded good.. but that last time it was changed was..... almost 2 years ago?
