Anyways for you 3.0 Neo diesel owners this is important stuff for you to know, It can mean the difference in driving or having dead turbo or blown engine.
The Neodiesels are prone to turbo failure mainly caused by having a bad MAF sensor that causes it to overfuel and overboost then the high exhaust gas temperatures frag the turbo.
The turbo is a Garrett 705954-8 some of the big diesel shops might be able to help you our or someplace like Speedlab might know a place to send it for rebuild if this has already happened to you.
This is a common problem with the ZD30DDTi engine. I suggest before you need to get it repaired or already need to invest in a exhaust gas temperature gauge and boost gauge for your van. I would also have the MAF sensor cleaned or replaced.
The engine crankcase breather is connected to the air induction system on the intake side of the air flow meter. This means the meter gets fouled by fumes from the crankcase. The computer gets incorrect readings from the airflow meter and adjusts fuel and boost levels to the incorrect readings. Thus the boost goes astronomical. A simple manual boost controller can help keep this from ever happening.
Some of the symptoms are things such as intercooler pipes sliding off, engine running rough, and higher than standard boost pressures.
Installing a oil catch can with filter media in it a DIY oil catch can works better in this application.
Helpful pdf for you 3.0 guys.

This is the reason I went with the 3.2. But the if properly taken care of the Neodiesel should be fine. Get that MAF cleaned or replaced and a filtered oil catch can ASAP! You can make your own catch can from a air water separator for a air compressor. A green scrub pad works great for a filter on the inside.
