This is scaring me! I need this in good shape for being my daily driver! If I were to let it sit at idle for a long period of time every few days would it keep the moisture down? Every other weekend (sometimes every weekend) I make a long trip (two hours round at the most) Do you think with the idling throughout the week plus those trips would help me? assuming my gasket is alright..

Hard to say. Are most of your trips very short? Like less than 15 minutes? That will build up a lot of moisture. (It makes for lousy fuel economy, too.) Of course, a lot depends on your climate. I'm in snow country, and it takes a good 4 miles to start to get warm on a cold day. Somebody in Arizona in the summer is obviously going to warm up a lot faster.

The two our drive is great, but if it's one hour one way, then it sits long enough to get cool, then another hour, it might not be enough. But if you do that every week, you'll sure be in better shape.

Sitting and idling isn't really good for an engine, either. If you're going to burn the fuel, you might as well go for a drive.

Yeah, my trips are litterally to work within an 8th of a mile and my wife is even closer... Call us lazy, but I just hate the cold haha. Not a Mainer in the least bit It actually started snowing pretty good out today, but it was real cold up to it. I'm not too hurt by the idea of driving more

All this is much ado about nothing.

Just run it to destruction (RTD, as they say). 1989 Jeep...what does it owe you.

That's sacreligious in the Renix world!!!!!!!!

I read about a guy in Alaska who had commutes like that. It was all good until one day the car would not start no matter what.

When the mechanics looked it over they found the engine was rusted together inside.

Not enough heat, for long enough time, to burn out the moisture.

That makes me sad! Either it dies from not getting driven enough, or it dies from driving it too much!

I CAN'T WIN! D:

i don't believe that for a minute.

what's that stuff that fills the inside of your motor... you know, the stuff you put on anything metal to prevent it from rusting... oh yeah, all the moving parts of an engine are covered in oil....

skife

why does there need to be vacuum? the only thing that system is used for is to relief the crank case pressure, crank case pressure builds when the engine gets hot (air expands when it gets warm) and there is pressure with blow by. Putting a vent on the valve cover reliefs this pressure. weather it vents into the intake manifold or vents into the atmosphere, doesn't really matter.

Of course it does, it's emissions illegal pretty much everywhere except in fourth-world countries. Also you have an unprotected entry into the crank case.

Bottom line is the 4.0L is engineered for a constant flow of air through the CCV system.

Unprotected with a breather filter on it?

nobody ever said anything about the legality of it.
can it be done? yes
will it function properly? yes

Is it against CF rules to discuss removal/modification of Federal emissions equipment? Yes.

salad

Yes. The stock configuration is protected from debris and water by the air box. A little breather filter is not.
