Oil carry over on even the original Vanagon Diesels is a problem. I remember
the crankcase breather at one point being recalled to address this problem.
Overfilling will definitely make things worse. A number of things could have
happened here.
Since you knew the dipstick may not have been accurate, did you pass that
information to the shop? Does your conversion have an inter-cooler on it?
That will have to be cleaned. It is even possible the failure was the turbo
itself and it was coincidental.
Since the Diesel is a compression ignition engine, once engine oil gets a
path into the air/turbo inlet the engine can run away. The only way to stop
it is place it in gear and stall it out. Many Diesels get destroyed from
this. It is probably why the truck and industrial engines usually run open
crankcase breathers. The 2007 and later machines that don't use an oil
vapor/liquid separator. Crankcase vapors also mess up the insides of
intercoolers. On modified vehicle one has to be careful to design the intake
track so oil cannot collect and puddle and then get sucked into the engine.

Subject: Diesel - too much oil saga
I've read the threads about too much oil with great interest as I took my
westy in for its first oil change here in Toronto. She has a 1.9 turbo
diesel from a 94 jetta, and the dipstick isn't "normal" in that a proper
level of oil is below the low mark. The shop put over 6 liters of oil in
her, topping it up to the full mark, and when I drove her it wasn't long
before she blew oil out, then promptly sucked it back in thru the turbo and
ran wild for a full minute (even with the ignition shut off). Max revs,
first a blue cloud and then a black one, and then she finally stopped.
Now she's very hard to start, appears to be pumping oil into the cylinders
and when she does fire up it's with a big blue cloud. Once the engine is
warm, it runs fine and will start fine. However she is on a steady diet of
oil (at least 1 liter every few hundred miles). She's in the shop now,
thought I'd ask here what people suspect might have blown... Mike said he
will start with a compression test.
I suspect the glow plugs are fouled, and some piston ring damage.
As a side question, anyone know where i can get a longer dipstick? Or
confirm what the correct one is so I can avoid this in the future?
