I started to use brass fittings that went inside the hose to attach but then thought if I used copper and could get it to go over really tight with some glue in the middle id get better flow and less of a chance of it clogging up at the bends

Oh and the parts all came from FCP But that one hose that I mentioned before just came in the box loose. Im callin FCP to ask

Is that hose going inside the copper union? If so, that's not good. Are those 1/2" or 3/4" unions? what is between the union & the hose if the hose is stretched over? What do you mean by 'some glue"? Copper pipe fittings need to be soldered if you are using pipe into the elbow unions for the hose to go over.

Those are 3/4 unions with 5/8s hose pushed very very firmly inside the copper unions. I used "Goop" adhesive that is supposed to hold up against gas and oil. They dont move at all after I put the Goop on the rubber hose

.I just think it will flow better since the piping doesnt get smaller around the bends, which one would think thats the most likely spot To clog

Just got an email back from Burger Tuning. They want only $129 plus shipping for just the can. I plan on getting this can and adding a provision to run a vacuum source to it with a check valve in place. I also plan on adding a brass filter to the inside of the can on the outlet side.

I plan on adding another vent to the rear of the cam cover and I will purchase another can at that time.

So im wondering if having the hose shoved into the unions like that will make it clog up around where oil hits the beginning of the hose. Think that will be a problem? They sure as hell aren't going to move now using that goop inside it though!

Don't count on them not separating. Oil condensate and heat will definitely impact the longevity of that bond of the coupling. The hose and the copper have differing expansion rates. I wouldn't trust it. Let us know down the road.

Use larger hose that fits over the unions and use some worm clamps. I wouldn't put then in the unions and use glue, it will leak I promise. Larger hose would be better too...have you looked at brass barb fittings?

Also noticed the zipties, that's not gonna work..

ummmh yeah...i would NOT do that....here is your fix...solder fittings into those copper elbows and push the hose over and clam them.

Good points guys. Thanks. I guess ill stay on the safe side and take it back apart before i finish up and use the 90 degree unions that go inside the hose instead, i thought zip ties were fine, but no reason to risk it

Been using 1 small one for years (technically 2 including stock). Routed like Dougy's, without the brass fittings. Just jb'd a plastic elbow to the top port. Atmospheric dump. No cam vent as it looses too much oil without baffles, and there is no room for baffles (cat cams). Many dyno runs, track days and highway pulls. I pound the fck outta my car, never have a problem with crankcase pressure.

There is all this talk about opening up the line set to allow more flow from the block to the catch then sending it back to the intake....through what, the PTC??? If you are using the stock PTC as your return you have defeated the entire purpose. The return hole is super small and restrictive. The only benefit you would get going through all this trouble is being able to see how much crap your engine spits into the catch can. There is no better flow, eventually its going to hit that small PTC hole and the super flowing vent system has just hit a wall. Unless you are venting to atmosphere it seems a waste. My 2 penny's.

Since there is high vacuum at the PTC, the reduction is not so much an issue on stockish setups. I wouldn't run it to the PTC. Better off using a larger ID fitting & add a idle vacuum closer to the box, as the 99- setup uses. Even the 99- PTC is significantly larger flow through, but has no vacuum nipple as mentioned.

Really depends what your goals are. VTA off the CC via a large filter makes the most sense, if you don t mind the stank
