Valve cover vent tube...... Reply #4 – January 27, 2013, 11:05:34 AM are you sucking crud into the trottle body? as in you happen to feel the guides are gone?as to how,have you tried running with it off. on the valve cover its going to vent to atmosphere.at the TB, if i recall , i noticed it made too much noise when adding thottle so im thinking thats the area your wanting a soltuion for.i would make up a simple flex hose from the tb and aim it down to the rear of the engine so it sucks in outside air.,, thats the easiest way around it.Whats the difference anyway, its normally sucking in stuff from the valve cover and sending down your intake runners,, why not just insure its fresh air only.i would not cap off the valve cover fitting though, and if you see crank case vapor coming out, then it may be a little smokey under the hood depending on what your reason is for wanting to do this. better yet,elbow and 90deg out to your air box along the bottom. this will allow the intake to sill pull crank case vapor but the fitting up at the TB now becomes something you can cap off.i would enter the air box on the correct side of the filter so the crank case vapor would be forced through the filter. the more i think about it now, the more i like this idea. this would allow you to manage / monitor if your valve covers are letting vapors or debris out and you can easily and visually see the dirty indication on your inexpensive air filter.

Reply #5 – January 27, 2013, 11:08:53 AM Quote from: 88turbo;408132cap them off, I've been looking for that tube serously?thats easy,, especially if you have a truck stop around... its just plastic tubing.the big trucks use plastic lines for air prakes and such that come in many diameters. eventually the air lines transition to metal but there is a boat load of plastic tubing lines in a big rig. now just use a heat gun or a pretty good hand held hair dryer to heat up and shap the line.i think lowes also offers black water line tubing in a small rolled up baggie as well that i spied out one day...

Valve cover vent tube...... Reply #6 – January 27, 2013, 11:20:12 AM My car has the tube as it's supposed to be. No issues from it. I am just curious if I could eliminate than tube completely. IF I can, I'd pull the tube from the t-body, tap the hole there, and install a plug, and have no venting coming from the valve cover. Would too much pressure build up in the engine? Quote Selected
Valve cover vent tube...... Reply #7 – January 27, 2013, 11:21:26 AM I just put a vacuum cap on the TB and have been running the Coupe this way for years. When I had the stock valve covers I just put a vacuum cap on the nipple on the filler neck. Now I have the tall Motorsport valve covers so I did not have to worry about the connection of the filler tube on the stock valve covers. When I built the 331 a couple weeks back I noticed that the tube on the TB washiznitting my hood so I pulled the metal tube out of the TB, drilled it out, tapped it with a NPT taper tap, and plugged it. Now I have about 1/4" clearance and it cleaned up the overall looks.Darren Quote Selected

Valve cover vent tube...... Reply #9 – January 27, 2013, 11:24:44 AM maybe its not all that important, everyone else is happy with capping it off it seems.i thought it would be nice to have a point to monitor blow by but i suppose you'd see blow by if you take off the oil filler cap.if you still have the pcv tube in place, thats where pressure would get relieved from now on so hopefully that chimney thingy down deep isnt clogged.

Valve cover vent tube...... Reply #11 – January 27, 2013, 11:55:20 AM The PCV valve is in the rear of the lower intake so I think that covers what you are worried about. I have a vented oil filler cap on my passenger's side valve cover. You can see what I am talking about here:Darren Quote Selected

Valve cover vent tube...... Reply #13 – January 27, 2013, 12:57:32 PM Vent the valve covers leave the PCV Valve in place. Plug the other end of the removed hose and drive off in to the sunset. The closed PCV system is federal law that is the only reason it is designed that way from the factory. VENT BOTH COVERS TO ATMOSPHERE WITH AN OIL BAFFLE INSIDE THE COVER!! POLISH THE PARTS AS USUAL AND ALL IS GOOD IN THE WORLD!!! Quote Selected
Valve cover vent tube...... Reply #14 – January 27, 2013, 01:19:32 PM With my intake over the driver side valve cover, there's really not room for a vent cap. There is on the driver side easily. I need to measure everything, but I'm not thinking one will fit on the driver side., Quote Selected
