Ah, the "Y-hose". It looks torn. Is that true? I look forward to seeing the inside of it.
Ah, the answer to "What happens to riceboys when they grow up?" They become ricemen.
Hey JAG, it is the Y hose and yes, it cracked.
Here is a picture of the inside:
Actually, there were no deposits or sludge inside the hose. There was certainly some oil in there, but nothing blocking the pathway in any way. The connection on the cylinder head had brown varnish inside that wiped right off.
It looked exactly like the varnish that you spoke about that can be seen through the oil fill hole.
The rubber was really brittle and dried out. I guess that is what happens to rubber when hot oil fumes go through it.
I wonder if this is going to have any effect on my UOA which I will be sending in in a couple of months.
The rubber looked like cracked earth. What I mean by this is what you see in deserts or salt flats, where the heat and cold cycles cause rips and tears in the ground. I dont know of a better way of describing it.
I really wonder if this could have caused my higher copper levels, which Terry said could be related to the PCV system.

Thanks Stoic Dude. It's so clean so the PCV valve and suction jet pump is probably clean and fine. I doubt replacing the hose will affect your UOA. Likely you'd have to allow dirt to get the engine for that to happen. I can't remember, what's the engine's typical OCI, oil choices, driving habits, and total miles that's kept your PCV system so clean?
Simple Gifts, that was hilarious!

Veedub,
I assume you've frequented the VW/Audi forums and these engines do use oil as any engine can.
I've got a 99' 1.8T and it's used about a half quart every 5,000 miles or so and gradually went up to about a quart in the same interval. Have 145,000 miles on it and have only used Valvoline Synpower 5W 40 since 15,000 miles. First 100,000 miles went between 8-9,000 miles per my UOA's.
Cosmic,
That's really interesting. Did your engine start using oil from day 1 or did it start at some point?
Yeah, I do spend time on vortex and I haven't heard about too many folks having consumption in their 1.8Ts. But that doesn't mean they aren't out there.
BTW, kudos on running synpower in 8-9k drains. That's gutsy and the fact that your engine is still going strong at 145K says a lot about this oil.

it is very normal for that rubber to crack like that. Pretty much every 1.8T has most of these rubber parts replaced several times.
It is also normal for them to use oil. Most of the oil is from the turbo. Open up the lower hose on the intercooler and watch up to a half quart of oil come out!
