who's got a picture of oil drain line setup for an AAZ Vanagon

Subject says it all.  thanks, Paolo

Nothing that clearly shows it right now, I'll grab some shots tomorrow morning for you.
I'm using a braided SS extension hose that I got from Brickwerkes in the UK and a metric coupler combined with
an original Vanagon turbodiesel turbo drain from Groschi in Germany.

I had to suspend the hose with a SS zip-tie to keep it from hanging down below the oil pan height, and maintain the slight incline
from turbo to pan.

Which turbo?  It makes a big difference.

I've got the stock K03 turbo which clears the stock diesel engine mounts.  Also, does it make sense to T into the original drain in the block as well as the oil pan.  Thanks, Paolo

How bad would it be to just use the original AAZ block drain?  It's above the oil pan, and only a little oil would remain in the bottom bend.

The oil would have to flow uphill to get into the block drain, basically, and at least on my T2 the drain line interfered with the motor mount.

Paolo, here's some shots of my setup; Vanagon turbodiesel drain line, and the extension hose. Very little room to spare up between the turbo and motor mount!

Jerry, that looks like your turbo's center section is not clocked properly.  The supply and return ports of the turbo should be within 15° of vertical or bad things happen. 

[Syncroincity]

Not clocked.    Not with those pipes, anyway... I'll need a flex supply line, and something different under here as well, it's within a few mm of the mount as it is.

I've done a couple K03 Vanagon installs, but both on 1.6TDs.  On both I made a flange and a tube coming off it pointing at the port on the pan.  That allowed PERFECT clocking.  I just bent the supply to match.  I've looked for pics, but haven't found one yet.

What advantages if any does T'ing into the block drain provide?  Thanks, Paolo

provides no advantages.. the oil would have to flow up hill if you used the block drain..

its BAD to make oil flow up hill out of your turbo, it makes the oil seals leak..

The block drain is still downhill from the turbo in a vanagon when using the AAZ exhaust manifold.  Teeing into the block drain would have a benefit.  Because the vanagon turbo oil return port on the pan is at below the oil level, there is some potential risk that excess crankcase pressure could push oil from the pan up the return line and past the turbo seals.  Teeing to the block drain would remove that possibility.

ah, gotcha!!

Wouldn't crankcase pressure just push the oil back up from the block drain hole then?

[libbydiesel]

I don't really understand your question.  The block drain port is way above the oil level.  If there were any oil in the line it would fall down to the pan port.  Any crankcase pressure would be equal on either side of the oil in the drain line below the block port and there would not be any pool of oil in the upper part of the drain line.
