How effective is the Provent mod.? How hard is it to install? Wife is complaining some about the "smoke" from the EHM.

I have a Provent, and while it took a little plumbing ingenuity, it fits. And solves the oil-in-the-intake problem.

I also have a problem with what is called the EHM.

Besides being illegal, do you not understand that the single modification consisting of routing the blow-by back into the intake removed about 80% of the pollution pre-1967 vehicles made, and that by performing an EHM, you turn your vehicle into a pollution machine?

Please, please, please, do it right: put on a Provent or some similar system. Don't just dump your fumes into my air.

Would you mind elaborating a bit on what you have done with your EHM by routing the gasses into the airbox.

Surely the oily vapours will clog your air filter in no time although you say you wrap something around, confused but interested as i'm just
running a hose out the back at the moment but i don't like it as it is.

I think you may also run the risk of clogging up your MAF sensor if you do what you've done.

I had photos, but ended up deleting them.

But, basically, I took the EHM and ran it into the airbox. I used a proper fitting on the side of the airbox. Inside the airbox, I zip-tied a marine piece that is commonly refered to as a "Bilge-Diaper", made of virgin cotton around the fitting. The bilge diaper catches the oil in suspension. I secured additional bilge diaper material to the bottom of the airbox to catch any oil drippings. The remainder of the gases are then pulled, sans oil, into the intake side of the filter. Nice clean air for my CRD, without any of the nastiness that was building up. I check the filter monthly, and so far, it is doing well.

Right.

Or, you could just re-plumb it to go into your airbox, and add a wrap around it to catch the oil. The fumes are pulled into the engine still, but the crap is filtered out. On shutdown, you smell it a little, and when idleing, but that aside, it is preventing the crap build-up on the intake side of the engine and the oil ingestion. I just have to change my airfilter at oil changes.

That's how the first PCV systems worked as mentioned in the above link I posted

You have to have at least 1k posts before you can start reminding people of stuff.
