Vanagon AAZ runaway

You'd be wise to take libby's advice 100%

Good luch Chris

lol yes, already have used the "libby bong" method for filling my rad

The turbo seals are not positive seals.  They are like piston rings and will never seal 100%.  In order to avoid leakage past the turbo seals, you need to allow proper drainage.  The oil drains just from gravity and so if anything impedes its progress, it will leak past the shaft seals similar to the way an ice dam on a roof will cause the water to back up into the shingles and leak into the house.  In other words, if you did plug the oil return and then fill the cartridge or pressurize it, it would leak profusely even if the seals were working properly. 

It would likely be possible to weld the wastegate hole shut and add an external wastegate, but modifying the drain in the way I described would be easier.   I actually just did this to another K14 a couple weeks ago and so the process is very fresh in my mind.  The details I gave should allow you to accomplish it easily.

If your pan looks like this

(Ignore the welded plug and the three holes) - I was told later that the bolt that looks like a drain plug is for the turbo drain line - so use that for the lowest possible connection of the hose. Also, the hose needs to be good to 500F but does not have to be wire braid as there is zero pressure.
I used hose from the local parts store. It was made by Gates and has a 5/8" ID - possibly overkill size wise.
Here is a link to a good fitting site

IMO, any turbo you choose, clocking the drain line will still be required and they will all present a challenge of some sort. May as well solve this one.

i thought all vanagon diesels were NA only. my pan does not have that oil return port. my buddy is offering me a VNT turbo, which would solve the wastegate/oil return problem, but then there is the whole control issue.

The ones we got in the US were NA, but the rest of the world had the option for turbo-diesels, that's where that pan is from. Quality German in Cali has them in stock.

Here's a modifed pan for sale;

I'm fighting the same battle, hopefully I'll get some wide-bore drain hose on it this weekend.
