HI guys. I was curious, where is the hose from oil filler neck going to? and what is it doing?

Smitter

which one? there are 2.
one goes to the uim and has the pcv in it.
the other goes to the primary turbo inlet pipe.

unless his car is a 95, i think they capped the nipple that goes to the turbo in the 95 so there would only be one hose, to the pvc...

thanks. my car is 95 and it has only 1 nipple. what is the purpose of this and is it possible to disable it. any side effects?

Yes your car will explode and be covered in oil.

The nipple allows any pressure built up in oil to be vented. If you block it off it'll end up blowing out your dipstick or something else causing a oily mess. The line runs from the neck to the plastic primary turbo inlet. Just keep it.

mine runs nowhere. the hose is just pointed down and vents inot atmosphere. its not capped but it does not get vacuum either. will it cause any engine damadge?

Smitter

are u running a single turbo?
you gotta vent the crankcase or your turbo return line will not drain efficiently. the turbos will then leak and blow smoke out the exhaust. u cannot cap the line, why would u want to anyway?

It won't cause any damage. However, if you have any oil creep up the oil filler neck, it will make a nasty mess in your engine bay.

my car smokes blueish on startup. afetr its warm, it stops smoking. can it be because of this line not going to primary turbo inlet?

Possibly. The easiest way to test is to take the oil cap off, and then start the car. If you don't have the same smoke, then it's a crankcase ventilation issue.
