hey guys i have a question about the breather box n the back of my d15b7.Can i just delete that thing entirely?whats that open hole go to?the problem is the civic is smoking badly and idk if its rings bc i haven't done a comp test.at any rate i replaced my pcv calve and it didn't help my smoking problem so i wa like i wonder if all that emission crap is majorly clogged.theirfore delete it since we don't have emissions in my state.can i delete the box on the back below the intake or do i need to replace with an oil catch can and do the same for the car coal canister because i heard thats for the gas tank to vent to yet i have a fuel smell in my car.thanks for all the help and insight as always guys.

 

Describe the problem in detail. What car? What color smoke? When does it smoke?

 

blue smoke,itll smoke when i leave stop lights sometimes when i shift and when i stop itll catch up to me.if i get down on it itll leave a trail i promise.i know this wont fix the problem but after my rebuild id like to have eliminated some stuff from the bay

 

d15b7 eg sedan

 

Sounds like your valve seals maybe bad.

 

check the seals and do a comp test first, as far as emmisions just google, i pops right up how to properly delete it

 

you can remove the black box, that is part of the stock factory airbox

 

He's talking about the crankcase breather box not the air filter.

You should keep the pcv (positive crankcase ventilation) system in place or sludge will build up and eventually clog your oil galleys/lubrication system, cause crud to build up, oil seal leaks etc. The 'hole' comes from the crankcase/oil pan area and draws air/blow-by through the box/pcv valve to the intake to be burned. Fresh filtered air is drawn into the valve cover/engine through that little hole/hose in the corner.

Your engine smokes because it is worn (valve guides/seals/piston rings/injectors), poorly tuned (running rich/needs a tune up) or improperly configured.

If you remove the pcv system (not recommended) use synthetic oil and change it often. But really we don't want to breathe your crank fumes.
