However i use the word lifters to explain my self somehow & the mechanic just brief me about the oil compsumtion & the experience he had in the past & what can be the possible reasons the engine's burning oil.

My warranty covered all the cost,i just went & drove off out the shop.

Yes,it's normal to have some sort of oil loss between oil changes,we all agree in this one.

I believe that if the PCV wasn't necessary for all modern engines then why is there for ? probally i'll follow you on the PCV issue & get rid off it so i may be able to loss less oil as you do.But my VX doesn't burn as much as 1 Qt every 2000 miles

The noise i had in my engine was the tipical ticking noise,right at the top of the engine,my mech solve the problem & the engine runs as quiet as you can imagine the work is covered with 50.000 miles or 5 years.

I regret not to step by at the shop & had a look at the open engine so i can gain more knowledge about how the isuzu 3.5L engine works.

Plus your input was refered in your personal experience agains my mechanic.Your believe the problem was solve by getting rid of the PCV,my problem can be the rings or otherwise,who knows.

What the mech meant afterall is that isuzu fail to support its customers by ignoring the issue,they turn their back on you,me & all the rest of us whom purchased their products.

I not sure,but i think the engine you are talking about is the 2004 3.5L with the direct injection system that came with the axioms which really needs the ECU software upgrade & the wiring harness replaced if you want it in the VX

If i had the opportunity i'll deffinetly drop a 2004 engine into the VX.
The PCV (Positive Crankcase Ventilation) valve, came about sometime in the sixties IIRC, it was a measure taken in an effort to reduce air pollution.
Before that, excess crankcase pressure was vented into the atmosphere through "breathers", either on the valve covers, or sometimes through the oil fill cap...

This has been a presentation of "Your internal combustion engine & you, the early years"...
