Anything look wrong with the After picture? This nipple was drilled and welded into my turbo, and had a hose from it to the oil filler neck on the driver's side of the engine. Is this a normal installation procedure?

 

venting the crankcase w/ a mild vacuum.

 

Would that cause oil to fill up in your intercooler and shoot out your BOV?

 

Yes, oil can creep up the filler neck and go through that hose to your turbo inlet. Search on this forum for oil catch can setups.

One example: http://reganrotaryracing.tripod.com/catch.htm

 

The stock Fd is engineered the exact same way.

 

Your intercooler is now an expensive oil catch can

 

sorry, can't view images

 

Indeed we have a winner

 

couldn't the vacuum source be picked up somewhere else though? i'd hate to have my new turbo drilled into just for a vacuum source. hope i dont sound too ignorant, the catch can install confuses me a bit.

 

another option is using a hightemp checkvalve and the exhaust to pull a vacume

 

If you install it safely, you can use a threaded nipple in the end of the air filter housing, along with an appropriate washer and some silicone to keep it in place. Drilling and tapping plastic is kinda weird the first time you do it

Btw, this K&N filter actually came with the threaded hole already in it, I can find the part # if you'd like

 

Off topic****
Goodfellafd3s what kind of blue heater hose is that. I need some and can't find the name of it. I've heard it's nearly indestructable lol.

 

i like that idea much better

 

Yeah, if I get the TII, I'll definitly be putting the catch can in. My previous turbo setups sucked because of the excess oil.

 

Here ya go:

ATP's website was down for a while, or at least that link was.

If you really want to get crazy, you can order the DEI fire sleeving off summit racing in the 1 inch diameter and use that to protect the blue silicone hose.

 

To continue to be off topic..

An easier way (no silicone, no tapping) to do it would be to use a rubber grommet and a barbed fitting.


Trim down one end of the barbed fitting so that only 1 or 2 barbs are left. Drill a hole in whatever you want to plug your hose into and fit your grommet into it. Now just stick the short side of the fitting in the hole and attach the hose to the other.

 

another product ATP Turbo sells is a "QuickTap" it's a vaccuum nipple that will mount to any silicone adapter seals itself up nicely and everything.

Rich: lol i was like "wow that looks like my...oh wait it is."

kevin.

 

Yo kevin,

yeah, it looks familar huh ?

the quicktap from ATP is only supposed to be used on boost sources, not on the compressor inlet. According to them anyway

 

Take the line off and put in a catch can. Under vacuum (manyly high speed deceleration) this sucks the oil right out and throws it right back into the engine. This can cause excess smoke, not to mention a mess inside your pipes. I just use a water bottle! HA, ...cause I don't have the money for fancy polished Gready catch cans! This allows the crankcase to ventlelate, and not causing any vacuum. You will notice "not alot" of oil coming out this way.
