Under Compression Engines In Kia/ Hyundai Dieasel Models

[arjunal]

most of the hyundai/kia diesel SUVS ,(2007,2008models) need engine overhaul even though they haven't done 100000km yet.Is there any special reson for this?

Bullsh*t.

Sad to see that you haven't changed that shortsighted mentality of yours even after all these years.

Once a blinkered idiot, always a blinkered idiot I guess.

To The OP, Most modern diesel engines are completely differrent beasts than old lumps like the Toyota C, L engines and the Nissan QD's etc. Stuff like common rail injection, Variable geometry turbos and so on all lead to an engine that has much higher stresses put upon it than the diesels of old. That is partly why modern diesels are very powerful and even more economical than ever before. All in all, this means that durability is reduced somewhat compared to the older lumps that could take 200-250,000 Km between rebuilds.

This is not a problem common to the koreans either, even modern Toyota common Rails like the D4D's found in the Prados, hiluxes and so on can do maybe 150,000 Km before they too need to be redone. So contrary to what the so called "engineer" who replied first tells you, this is a problem common to most modern diesel engines, simply because of the stresses put on them.

Another factor (In SL at least) is the quality of our Diesel. Most modern engines need clean diesel with a very low Sulfur content. Even our Super diesel is not quite good enough compared to what you get in other countries but it is certainly WAY better than the normal diesel. This is why all agents who sell modern diesels generally say very clearly to only use super diesel. Unfortunately, because the Korean SUV's are pretty reasonably priced, most of the time our donkeys (like the "engineer" up there) decide that they know better than the agent and the manufacturer, and pump normal diesel. Which of course leads to the engine getting buggered early on.

Members,

my opinion they had not maintained properly with regular service.

If any one has service records oil filter changed at what kilometers then it will be helpful to other members in future.

Its not the bad built quality, its about the cheapness. Korean car's engine block and crankcase built with different raw materials with deferent percentage.

yes, that is the meaning of quality is low.

although mine is mechanical injection and runs fine on normal diesel, used to pump super whenever it was available until the recent price hike!

Now pumping super diesel is like pumping petrol

To be quite honest machan for old mechanical pump motors (or even EFI diesels that dont have turbos/common rail etc) I think normal diesel works just fine. The Hilux has always run on it and its still doing well (knock on wood lol)

suppose we aint getting answers from "Flash_Bang"

Have either of you owned Korean vehicles? Stop talking out of your asses without backing up your claims. This kind of insular mindset is prevalent among the majority of car owners in this country because pissants like yourselves do nothing except expedite the perpetuation of retarded notions like those quoted above.

So, it is ridiculous to pay a s#itload of tax money to the government and buy a Diesel Korean SUV that needs expensive super diesel....

Instead, it is better to pay less tax and buy a petrol Korean SUV....

Please tell your opinion.

Its not only Korean SUv's genius, EVERY modern diesel engine needs super diesel. Even the hiace KDH200's ideally SHOULD be run on super.

Plus, the reason people buy the diesels is because of the permit prices.
