What is This?? I took off my Intake today to clean it after i washed out my engine bay. I noticed that inside my intake there was some sludgey dirty stuff in one spot only and it was where this blue tube connects to the intake. it connects the at the Valve cover and to the intake. The Intake was attached to the vehicle before i bought it.

so if someone could enlighten me on what this is and What it Does i'd apprecitate it. thank you!

 

That blue line (also the grey line in the back ground) are crankcase/valve cover ventilation. It's normal to see oil deposits, very slight carbon deposit build up there (thus the need for a catch tank so all that crap is not recirculated back into your engine).

Looks like you have OBD2 F22B1 right?

 

A clamp on each end might help keep it clean

 

If you are seeing oil in the intake tube before the throttle body that is only normal if something isn't working properly. Your Positive Crankcase Ventilation Valve is clogged and/or you have excessive blow by and the pcv system is unable to handle it. That would cause oil to back up the valve cover intake hose (blue hose) and into the intake tube.

The blue line is the fresh air intake feed into the valve cover & the grey line is for the crank case gasses to be sucked into the intake manifold. that is the way the PCV is supposed to work. On older engines it doesn't always work that way though. clean/replace your PCV valve and hoses and see if that makes any difference.

A catch can works to stop oil from entering the intake manifold. It could help clear up some back pressure issues with your current PCV system. Allowing your intake to suck more crank case gasses with less restriction. Therefore allowing the fresh air port to bring in air rather than push out dirty oil.

 

lol yes it is a F22B1 but OBD2....im not sure. i heard obd2 has 2 oxygen Sensors but for some reason i only have 1 oxygen sensor and its around the cat. so im wondering if i am obd 1 or 2.

 

so am i goign to have to replace alot of hoses? ot are you saying to replace the grey hose in the background of my picture?

 

"Replace the two hoses with oil/gunk on them and clean/replace the PCV"

You're not replacing a lot of hoses - just the two troublesome ones.
