Burning Oil?

[Ikkesh]

Is it Normal to be adding a quart of oil a month into my VX?

No Blue Smoke, No Leaks, Where's It Going?


Ideas?

[JoFotoz]

Yes ...and No....

Depends on your mileage.....which ya dont state.



Give up some info...

128,000 miles

I baught it used, I Just wish i knew who used to own it to find out service info on it.

[ScottinMA]

The point is...how many miles do you drive before before adding a quart?

[Ikkesh]

1 quart For every 3 Fillups I think.

Not to be too much of an alarmist, but...

This particular motor (and some say 99's in particular), tends to use oil.
The oil level should be checked at every fill up & the PCV valve ($3-5.00), should be changed every other oil change.
The result of not staying on top of your oil level, is motor replacement, no if's, and's or but's...

Use the handy search function using "oil consumption" for more...

99- 118,000 miles, used to burn 1quart every 1200 miles,NOW every 500 miles I've got to get a ring job before Moab. Runs fine,I just have to really watch it.

Oh man,believe me,you're not alone with this one if that makes you feel better.

I bought mines with only 38,780 miles last year around november,my odo reads 45,869 right now & it do burns oil,i drives the average of 15 miles per day;Full syntetic is the key to an longlasting engine (mobile 1 or amsoil),don't abuse it,use 5w-30 on cold weather & 10w-30 on summer. Don't play with this one.

My mechanic who's an former isuzu engine specialist told me that isuzu engineers oversight the facts that the ducts the oil runs throughtout the engine were too big & too few of them so a considareble amount of oil goes into the combustion chamber which shouldn't be happening,specially on high RPM's situations such as be in the highway or express ways when the oil pump pumps high amounts of oil as per demanded by the engine.

Isuzu knows about this issue,but's financially high the amount of money they would had to put out here in order to have that issue solve,which in fact is that isuzu will had to redesign the whole engine or build a new one for each VX,rodeo,axiom,amigo & trooper on the streets so they best move is to ignore the issue,so clever don't they ?

This problem is found in almost all 1998 to 2001 engines my mech told me,he had more that 200 isuzu troopers,rodeos & 2001 axioms just in his shop & about 3 vehicross (included mines) which had a few sticky lifters due the lack of use.

In 2002 isuzu overcome this issue with they new engine.

If you have the meanings $$$$ & if the vehicross means a lot for you,plus the value the VX will have over there & the overall conditions of your VX you should dropped an 2002 isuzu axiom engine with the less mileage you can possible find into it if isuzu had axioms for sale there.

The 2002 engine fits perfectly without any more mods,is like a plug & play stuff.

Plus this engine is more powerfull it comes with 230 HP instead of the 215.

Rebuilt is another option,but the oil conpsumtion can be back again,problally with less amount of loss oil.

When i got aknowledge about this issue my thoughts were : DAMN I SCREW UP,but after a found that many VX's made the 100,000 & + miles i believe mines can go that far as yours.

One of my co-workers have a 2002 rodeo with more then 200,000 miles on the clock & that bastard runs like an champion.

The secret : maintainance,that's all about he says,don't abuse it,just drive as you should drive an vehicule.

I guess I must be lucky with my 99 with 102,689 miles, I drove it up to Vail Colorado from Las Vegas over 650 miles and didn't burn a drop......

[VCrossfan]

Nice info Gussie ! !

[Ikkesh]

Heh was begining to think my Vehicross was "Retarted" err... I mean "Not Normal".

knowing this makes me feel better about my pourchase.

Paid $8,500 for mine
All I use is Synthetic Mobil One

I Just hope the Previous Owner Knew Enough to top his engine oil off under these circumstances!

My Mechanic said Comression is good Mechanichally everything is sound aside from that the only things triggering the Check Engine Light was the Gas Cap and MAF Sensor (of which I cleaned) and Gas Cap Replaced..

Strange though, Check Engine Light Went Back On a Week Ago After resolving those issues!

Got an Apt For Timing Belt, And Waterpump Just waiting for OEM Belt to get here. I heard to Use the OEM Timing Belt Due to Isuzu Warrants the Vavles if Belt Fails....

we shall see.

Join the club, I've been a burner since 30k...

unless you bought your VX new from a dealer or bought from a family member who was the original owner.. your VX is out of warranty they had 10 year 120k mile warranties in 00 and 01.. which cut in half upon sale to a non-family member

as for the check engine light.. what is the code? a lot of people have issues with their EGR valve causing check engine lights but iirc the code doesnt necessarily reflect that thats the problem... also when replacing the timing belt.. look around there are a few TSBs (technical service bulletins) that correct the timing belt replacement procedure as well as the torque on the intake manifold (the intake manifold gaskets might be leaking due to a mistake in torquing the bolts.. that could cause a check engine light too)

oh and i burn about 1 quart every 3k miles using mobil 1 synthetic.. but it all happens fast.. like i will be fine for 1000-2000 miles then all of a sudden 500 miles and ill be 1/2 quart low.. i just check every gas fillup and keep a bottle of oil on hand so that i can keep it right on the full mark at all times.. if you pay close attention you can spot warning signs.. im to the point where i swear i can hear when my VX is running low on oil

I guess you do eric.

My mechanic told me the 1srt time i had the VX serviced that isuzu shall had built a specific engine for the VX,some sort of 3.7 to 4.0L,even though this 3.5L engine is a high tech he said that the weight-acceleration-speed-HP is just not completly right.
For his weight the VX should be propelled by at least 250 HP with a 280 PSI torque force which will make the VX way more powerfull & faster.

Isuzu probes that they are capable to build excelents SUV's,the fact that the VX won the paris-to-dakar rally twice over more powerfull SUV's with the 3.5L engine is an indication that isuzu knows they stuff.

But again,isuzu didn't had intentions to mass produce the VX so they figure out they'll not invest much of money building a exclusive engine,like how the jeep did with the grand cherokee SRT-8 with the 6.1L plus they were already in financial "recesion" so even though they wanted too they wouldn't be able to afford it

And i believe what he said because you can see right now powerfull SUV's such as the acura MDX with the same weight & propelled by an 280 HP engine,the jeep liberty with an 3.7L & 260 HP & the infiniti FX 35 with 300 HP

What makes the difference with our VX's is the 230 PSI torque at 3000 RPM he add.

If isuzu did dropped in an 3.7 or 4.0 L the VX will the most powerfull two-doors SUV on the planet

+1 on your oil burning issue - very common. I would suggest to stop using synthetic oil if you are burning it at that rate - the synthetic is great if the engine doesn't burn it, but it's doing you no good to put super-expensive synthetic if it's going to go up in smoke (so to speak) before it needs replacing.

If you have a K&N style oiled air filter, that might be the cause of your CE light. The oil fouls the MAF, so you either have to keep cleaning it or go back to the OEM filter (which a team of engineers decided was perfectly adequate).

Good luck!
