Could be from faulty injectors tips. timing out, gudgeon pin bush wear, and bearing failure. Start with the injector timing and injectors as that is the cheapest way .

Isuzu 4x4 3lt diesel orange engine light light on wont rev up idles roughly and stops smells horrible, has been sitting before 3 weeks before, with couple starts during that time with no problems


what is this?
"Isuzu 4x4 3lt " (my guess now the 3.0L diesel
D-MAX the truck not sold in USA but in what country????? why is this so hard,
that lamp (check engine lamp) means what?
get it serviced, or scan it. (pick one?)
what year. ?2009, ok now we have the year,
thanks.

like pulling teeth,,, now country, ?????
country, country country......

this is USA Forum and you ask for facts on a truck not sold here. (why?)
and fail to say where you are. why?


so then i said scan it.
but guess what?, our Scan tools may not fit your non USA CAR, but what is the point ,after all i cant just mail you a USA scan tool.(bad idea)
nor can you find one in say Thailand.(pointless )
so why ask us?
lacking COUNTRY>

ours are OBD2,(obd2 is a USA invention)
others might copy it, sure. but it's OURS.
but that is a USA spec, tool,
in say Europe this IS and EOBD. tool
In Japan its JOBD.
Only your dealer of your truck can answer
this, what tools works in your truck, that country.

see?
why in the world do 1million posts here
and only like 4 show,country.
sorry cars are not the same world wide
nor are
brakes
EFI systems
smog parts.
lighting
safety parts.
scan tools
and and endless list.... ILL STOP HERE.


now my wild and useless guesses on TDI diesels.
1: get is serviced yet>?
2: filters>?
3: bad fuel (diesel, or contaminated) (checks)
4: scan it? using the tool that matches what ISUSU used in YOUR COUNTRY?
5: there are lots more tests, , the book at the dealer covers all this , called a Service manual,, and test to do...

Hi there I am thinking about replacing my 2001 3lt diesel trooper motor with a 87 3.3lt isuzu diesel motor what changer would need doing can I use the 3lt gearbox and the 3.1lt gearbox and engine mounts


The main problem that you will encounter is the mounting of the engine. You might end up having to customize the mounting brackets and reorder some components of the engine compartment in order for the replacement engine to mount correctly. You would have to balance the engine as well and pair up it's output with the capacity of the differentials. I think you can use the present gearbox but results are not guaranteed and it's not an easy fix.

check egr too, Lee

98 Ford Explorer engine/exhaust noise


When catalytic converters go bad, the porcelain matrix inside comes loose and is noisy.
But you can just unbolt it, break up the loose chunks, pour out the pieces, and it will run better than ever.
If you don't pass the next emissions test, then replace it.

But it could just be the heat shield rattling instead.
Take the shield off first, to see if it goes away.

Loud rattling / buzzing noise from engine when cold not seconday air pump or air valve as already replaced.Timing belt,water pump and aux pullies all checked and ok.The colder the weather the louder the...


If the rattling changes with the revs of the engine, it might be that the valve compensators are either worn or not getting enough lubrication. 20V engines have quite small oil passages travelling to the head. They tend to clog up with gunk if the oil change is not frequent enough.
