Air Cleaner Thread#83

Already know this is placing myself in front of the guru firing line..but am through with the stock air intake system.
Mostly with the fact on how the oil separator functions dumping blowby back into the turbo/intake manifold.

Cleaned the intake after the EGR modification two summers ago, and am amazed at how much crap is back in there with <15K.
Some oil 'mist' might be good to lubricate the turbo, but definitely not the cake that is present.

Aside from the 'hot air intake', increased flow of particulates, and defeat of the highly engineered german system..
what OTHER significant obstacles are present?? Have an external oil separator worked out, on paper.

Think am willing to sacrifice the bads, for the potential upsides..quicker turbo spooling alone.

Want to sell all your stock stuff?

How much do you want for all the STOCK air filter/oil separator and turbo tube stuff? Shipped to 19454.

I'm trying to collect everything I need to convert a CA setup to a FED setup.

So far I have a manifold on the way.

You won't get any quicker spooling, only more noise which makes people think its spooling quicker.

If you don't like the oil mist then either vent it to the atmosphere (road draft) or use your own separator and block off the stock one.

If you take a steel wool pad, stretch it apart and stuff it in the oil separator, it'll prevent the oil from going into the intake. You do have to find some way to seal the top of it though, I haven't gotten to that yet.

You are not of the belief that without the complex route of incoming air that a T3 will spool any faster?
Am positively anti road draft for obvious reasons, but what do you think of the mist..does the turbo really care?

At low speeds there is no airflow restriction. As I said, the increased noise makes people think there is a change. Put the car on a dyno with and without any air filter system at all and there is no significant change in the torque/power curve or an increase in power.

Reasons being what? Almost every semi on the road, all 95 million of them and their 10L+ engines, use road draft tubes. Better go do something about them. There is nothing wrong at all with road draft tubes.

It does. Mist is little droplets of fluid hitting the blades. It will cause more wear than if the turbo only got pure air.

If you don't like the mist get an Enviroguard CCV filter.

Spool time has nothing with power/torque output AFAIK.
Agree that there would be no change on a dyno, but rather the overall everyday driveability might be improved.

Hopefully their diesels have less blowby than ours, to say the least.

Great point, all the more reason to get that s**t out of there.

Thats a contradiction. If there is no significant change in output then there will be no change in normal driving either.

An engine is an engine, they all have blowby. Ours only appear worse because of the visible oil mist. Thats the kind of thinking that got particulate filters put on modern Diesels, "If it looks cleaner it must be cleaner."

The only problem is finding prices. I have a feeling that despite their simplicity they aren't cheap.

Hey forced, which one are you running the 08 or 09? Cost?
The perfect CCV oil separator?

None yet. I don't know their cost.

well, let the hazing begin.. after a poor compression test on my #5=11-12psi, the decision was easy.
do not even have to start on the size of the filter, another is on order even though it is rated>110hp
