Intake Mods

[R.O.R-2.0]

I dunno about that, they were vented back to the intake(like they are on almost all cars for a very long time) because it is cleaner, and there is nothing for the stupid owner to clean/empty.

the valve guides are self lubricating bronze, no need for oil to lube them.

no, someone else has told me this too.. i really hope someone else chimes in with where they found that info.. im not smoking crack, ive heard about the VW CCV system lubing the valves before..

[truckinwagen]

its a common misconception, propagated mostly by the G60 folks.

im not talking about CCV systems in general..

im talking about the CCV system on a VW IDI Diesel.. ive heard from many reliable people that the oil mist in the blow by is to help lube the valves..

About intake
I like it,but I always think that wire must be inside tube if it`s rubber,for vacum

shop vac hose works great.. its the right size, and its made for vacuum..

I used aircraft tubing; It is supported with wire on the inside.

I have heard from 2 different VOA mechanics and Dakotakid on this forum that VW designed the oil in the intake for an upper cylinder lube.
There you go ROR.

I think it actually says that in the 1.5L SAE paper.  Yes, the CC vapours are vented to the intake to save planet earth, but a happy benefit (according to VW's engineers) is that it provides lubrication to the intake valves and upper cylinder walls.

[rabbitman]

So the exhaust valves don't need lube but the intakes do?

The upper cylinder thing makes perfect sense.

why even modify it? does it need to be deleted for your particular style of intake to work? the breather was vented into the intake manifold so the blow by gasses could lubricate the intake valves..

Now you're just making things up...

i hope your being sarcastic? lol.

Thats an ancient old wives tale invented by techs to get complaining car owners off their back about oil in the intake tract. Lube the valves... thats rich.

Getting back to original concept here.  I used metal dryer vent hose, 3 inch from the front of the air box on mine.  I have the other not so great, NA 1.6 set up.  The metal pipe is able to be formed into an oval that gently returns to a full 3 inch circle as it snakes over the alternator.  At that point it attaches to a 4 inch to 3 inch reducer that I custom cut and filed in place on the left side of the radiator.  That gives me 4 inch surface just behind the grill to a 2.5 inch oval at the box.  Looking for that ram air pressure.

All .5 lbs of it. 

Pipe held on with plastic pull ties.  Looks good. but louder than dense plastic weenie tube.  Thinking of a sound wrap on it, Maybe, between speaker box effect of intake box and megaphone style inlet it is a weird noise at idle.  After leaving a light it is back to standard diesel buzz.
