Hose ID

[Phil Rose]

Ok, then maybe it's a "dealer DIY". Whoever did it appears to have
"customized" to the extent that they've adapted a part that Audi
specifies for a different engine/model (the parts shown by Kneale are
for the ABY engine) . I'm rather surprised that a dealer would use a
"wrong" part (i,e, non-standard for the '91 200q/3B), although heck,
if it functions perfectly and has a longer service life, then I
guess--why not. Where is the crankcase pressure regulator valve
located--down near the lower end of the tube--or on the other end
where the hose joins the "pipe" on the passenger side?
