Oil catch can options

[HACK BLOCK]

It will.

The path is: from the valve cover, thru the catch can, to the intake manifold and thru the throttle body, then into the combustion chamber.

that doesn't sound right cause I see the line goes from the pcv to the intake manifold which is after the throttle body

 

[HACK BLOCK]

what's the line that goes to the intake tube?

 

[wsteele]

another question I had was I see that the pcv runs to the middle of the intake manifold but the reason I picked up the catch can was to try and help out the build up I keep getting on my throttle body. is there another line that I could tap into?

There is another hose on the passengers side valve cover. That nipple is up near the filler tube, but that is the fresh air supply to the crankcase (air flowing from the induction side to the crankcase).

 

[HACK BLOCK]

I see that is attached to the intake so isn't it under vacuum? and also I'm pretty sure that's the cause for the oil on my throttle body

 

[HACK BLOCK]

oh and I broke that breather hose that goes into the intake tube. idk if I can use a T fitting and join it with the pcv going into the catch can then have it exit to the fitting after the throttle body

I didn't think the fresh air line that runs from the TB to the passenger side valve cover was under relative vacuum because it is connected outside the TB.

My understanding of how the PCV works is fresh (filtered) air is supplied through that fresh air hose (Passenger side valve cover nipple to TB), flows down into the crankcase and then back up through the PCV valve on the drivers side valve cover, to the intake manifold (top center). The intake manifold has a higher relative vacuum, so that is what crates the flow, scavenging all the nasty vapors in the crankcase, sending it back into the combustion side.

well it's connected to the intake tube before the throttle body so it's definitely under vacuum but I can feel it sucking air into the engine through that line

Your correct, it doesn't go thru the TB.

The crud your getting on the TB is dirt/dust in the atmosphere that gets by the air filter.

An air filter is a compromise. If it does too good a job of filtering the incoming air it is too restrictive and doesn't allow enogh air into the engine thus robbing it of efficiency/hp. If it doesn't do a good enough job of filtering the crud out of the incoming air, damage to the engine will result.

so how would you explain the oil then?
