well, I found a small slit on the one on my turbo car.
Anyway to use regular heater/vacum hose to redo it? It looks alot different than the one on my N/A 5000.
Would this cause much of a vacum leak? I'd think so, but not much of one...

The following is from a response to me regarding pictures and problems that I posted only a few below yours. (It's entitled "Pics of Problems. Let's do it!")
Hope it helps!
I was able to persuade a 3" length of 3/4" heater hose to fit...

on the crank case fitting and the breather pipe with little difficulty. Audi just loves to change diameters like that. I didn't even think to try and check on the availability of the specific Audi part, which if available, I would have had to mail order! An easy $10.00 for the part and shipping.
Other spots where I found a small length of 3/4" heater hose can replace a more expensive Audi hose with 2 different (but close diameters) is the small hose on the heater return pipe to the thermostat housing, and the small hose from the rear of the block to the heater valve. Another place where it may work (haven't tried yet) is from the bottom of the expansion tank to the radiator.

I think the only downside is that the regular heater hose may not hold up to oil quite as well but the original one didn't either so what the hey! It may also be that NAPA or another who have bulk specialty hoses may have something better yet for heat and oil resistance. I didn't think a 3/4" would fit the bottom Audi crank case connection but Tom S. did it. I am going to check tomorrow. I am all for replacing expensive for less when it does the job.

(especially myself) certain turbo applications always seem to be a bit different than the NA counterparts, even when there should be no difference. I suppose that's by design.
But I have heard and read that any crankcase air leaks will cause the turbo's to not run "just right", even if the oil dipstick is not in tight, or the valve cover gasket is leaking!
I usually change these little hoses ev. 3-4 years, they seem to hold up that long, haven't gone longer so I'm not sure of long term, can't be much worse than the OEM ones.

I am positive that mine is OEM and the bottom connection is about a 1" cast nipple. I didn't ever measure it but just ordered a new OEM hose after I seen the odd size there.

and there is a difference then in this case too, mine is a simple pressed steel dome fitted into the block with probably no more than a 20mm hose fitting. Not a casting.

that's why I was wondering if anyone had done it on the 5kt...
I might just bite the bullet and get an OEM hose at the dealer...
