The problem with modern diesels

What is the legal issue with catch cans? I wouldn't of thought they would be an emission issue?

Who said there's legal issue with that?!! You simply collect the blow-by oil. You simply leave the PCV system as it is.

Another article by Allan Whiting, I didn't read it through this time but there is info there about catch cans for your reading pleasure.

Interesting, even though just about every diesel mechanic I've spoken to, read an article from, or have been interviewed, has said that can-cans are a critical piece of gear for all modern diesels fitted with the current pollution controls.
I honestly believe that governments and 4wd manufactures don't care about the longevity or reliability of current diesel vehicles. They just care about ensuring their vehicles meet the ever-changing emissions requirements to be able to continue selling vehicles.

The only way this will end or improve is if falling sales impact the economy.

You are right on the money I reckon. Gov's hold these companies to ransom to please the green lobby.

What is the carbon foot print to scrap, rebuild or make a replacement vehicle after a short service life. That doesn't seem to be on the agenda.

I would not like to be making or selling large caravans in near future as there will be no suitable vehicle to tow them any reasonable distance. Same for off road campers etc.
As electric vehicles take over, petrol and diesel will be more expensive as volumes decrease, especially in the cities.

Imo were a long way off from diverting to a different fuel sorce..
What I can't understand is why manufacturers aren't looking into combining fuel sorces..
Imagine a td42 turbo with a nitrogen injection?
That'll solve power and emissions problems..
And it's water..............

Personally I think solar is an awesome tech.
We just need to refine the efficiency and reliability..
An electronic 4x4 car would love the aus outback. No shortage of sun light.
But the capacity would be the killer.. 300k a day would make for a slow trek but very relaxing holiday..

"Many 4WD owners are tempted to blank off EGR valves and fit catch cans to trap crankcase oil mist before it can coke up turbos and inlet manifolds, but we’ve covered the illegality and perils of that route in our story: ‘Leave your common rail diesel engine alone’."

I think, if you leave the PCV system alone and simply fit a well designed catch can to reduce the amount of oil getting sucked into the intake, that should be ok. The idea is to collect the oil mist without affecting the fine tuned PCV system. I guess with a simple old school 4wd like mine(RB30 carby), catch can isn't a bad idea.
