Crankcase hose modding...
<center><img src="http://pictureposter.audiworld.com/4612/mch_2.jpg"></center><p>
Since Steve J. recently mentioned how problematic old crankcase hoses can be, I thought I'd post some info I've found about improving the crankcase system...
Even with a new CC hose, it a poor design.
Here's a couple ideas of what people are doing on thier type 44's.
Here's some pics:
Pic#1 "OEM VAG oil seperator catch can (Part # 052 103 495) installed on MC-2 engine. This seems to be a vast improvement to the crankcase breather system.Hose fittings are both 3/4"."

"Modified crankcase ventillation: a wire loom is fitted inside the large main hose coming from the engine. The loom works pretty well as an oil seperator and prevents the hose from collapsing under heavy vacuum. Some "T" & "L" fittings from GARDENA garden tools (www.gardena.de) where used in addition, in order to prevent from oil entering the intake system."

That metal replacement pipe is for the naturally aspirated...
engines...
The MC and MC2 engine use a different sized hose than the NF, etc. Won't fit.

does this mean no isv ?
I wanted out with my ISV ... but I had to make sure there was a hose going from the crankcase to the intake and back again .. or something ?? All I know is that I had to get it just right till the car started. But no ISV as of now for me.
