I think the problem is deleting the DPF

Yes, it's one problem. When the engine rev higher the black smoke is massive. I've never seen that on my old 1999 5L Hiace. What about the kdh200 model with 2500cc engine that doesn't come with a DPF.

I have the same kind of problem with mazda bongo, black smoke & oil level drop<br />

sorry I don't know how to check the intake manifold in kdh<br />

please check the turbo? & did you replace the injector seals during the injector cleaning process?</p></blockquote>

Finally got rid of the problem. Just reved hard while driving in the morning(becouse theres not much vehicles on the road.). Saw a massive black smoke comming out. After got back to home, put the van in idle (neutral) and rev hard few more times. Black smoke reduced gradually. now it's just alil bit of smoke. Thanks guyz.

As i think the problem couse by driving the vehicle under speed for a long time(in months). Carbon get diposite inside the exhaust(becouse of the low exhaust temprature, carbon deposites won't get burn).

Anyway thanks everyone....!!! :D :D
