Hmm... that's strange. You guys seem to have a ton of problems with D-4D Innovas.

We have a Manual J Diesel Innova. So far, at 19000kms, there seems to be no problems whatsoever with the engine. No hard starting, no stalling, no choking and the like. We sent it to the dealer once for maintenance checkup.
The fuel used is Caltex Power Diesel located at Imelda Avenue near Makro.
Fuel mileage of our Innova ranges from 9km/L in stop and go traffic, to a max of 15km/L in NLEX (night constantly at 80km/h).

Even though ours have no problem, I'm still concerned about this issue.
Also, I observed this when I was in school. I'm 3rd year HS this June.
I noticed that many of the Innova D-4Ds, particularly the G model (maybe because most Innovas are G), has a strange wind-like noise. The same goes for a few Hyundai Starex CRDi, as well as some D-4D Toyota Fortuners and Toyota Hiluxes.
I wonder what that strange noise is... and it's not the auxilliary fan.

The other ancient distributor diesels, like the ones in the 2.8 Pajero and Crosswind, sounds normal- annoying, noisy and clattery. No strange noises on those vehicles.

Either that or I'm just a plain crazy student.
