Ebay headers...updates?

[turbo mc kwek]

I've been working on it all day, and I'm pretty sure my NEW AOS is broken...

I didn't check it right away because I thought that it could not be te source of the problem since it was a new part and only about 500 miles old...

The hose to the intake manifold and the pipe on the AOS had zo much oil in it that it started to drip once the hose was disconnected...

Now my question: was I so unlucky to get a broken new part, or did it break because of something else?

Is it possible you overfilled at the last oil change? My first inclination was toward a bad AOS...

Well, I'm pretty precise on those things, so I would say no

I already ordered a new AOS @ pelicanparts (somehow it's much cheaper for me to order parts in the US, even with Germany being our neighbour country, and some parts are up to 50% cheaper in the US)

In the pelicanparts forum was something very interesting; There's a PCV valve in the driver side valvecover and one of the two vacuum hoses to the AOS comes from that PCV valve. If this valve gets clogged with oil residu or something, the vacuum on the AOS will rise and result in AOS failure..

There seem to be people that replaced the AOS four or five times in just a few hundred miles before looking any further...

Problem solved!!

I saw someone else on this forum who posted a movie with the very same problem as my car had!

Maybe this is helpfull for him to:

The problem was the oil filler hose... When this gets older the plastic gets hard... My guess is that, when I replaced the AOS, the tube broke when I removed it from the oil filler tube on the engine..

There's a ribbed part in the hpse where it bends... there was a crack in between the ribs.. When the engine was at idle, the tear was closed and the vacuum under the oil filler cap was good, but when the car accellerates the engine somewhat tilts over and opened up the crack. With this, the vacuum dropped and the AOS stopped working, resulting in huge clouds of smoke.

I'm happy I found the problem and the repair only costed 30 euros!

I strongly suggest having a shop to it. You will break manifold bolts and that's not a problem you want to deal with. I broke two bolts and ha to send the car to theachome shop for a week. Other than that I love the headers. One more thing, don't use their hardware, order our own gaskets etc.
