air breather filters

[and1chewy]

what do we think of weapon r air breather filters? i was looking at andyautosport.com today and they have weapon r air breather filters for like $10 and free shipping. was thinking about picking one up for my valve cover outlet tube. also what have people used done to plug the hole in the intake tube after deleting the connecting hose? kinda generic but i was contomplating cutting off the end of a golf tee painting it black and plugging up the hole like that. any input?

You should probably get a catch can so it isn't leaking oil all over. But other than that, they work fine.

Ditto on the catch can, our cars tend to have blowby and tha can would capture all the oil instead of the engine bay.

 

[and1chewy]

So its like the filters a good idea but it should be incased? ###### a stupid question but how does the oil get returned or is it minimal oil that would actually go into the can?

If your car is still using a MAS, you should use a sealed/metered breather system. Open air vent filters will eventually introduce unmetered air into the intake, fuel trims will change fueling and you'll run richer than you should in closed loop cruise, or leaner than you should at idle and under light deceleration, depending of course on the amount the PCV valve is opening in each situation. It seems about as popular as venting your BOV anymore. It won't kill your car anytime soon, but it's just poor form.

The catch can would be placed between the hose coming out of the valve cover and the hose returning to the intake. When the gasses flow from the valve cover to the intake, depending on the condition of your engine it may contain a lot of oil (blowby) and this oil would get burned with the combustion mix if no can is present.
If you install a catch can the oil gets trapped in the bottom of the can which you.. in turn would empty out by opening the valve in the bottom of the can whenever needed. It doesn't get returned to the engine

i see i was interested because i was reading the tech guides and it was one of the first stage things to do to free up horsepower.

The filter alone works fine, but like said before=poor form. Also, ive been running a breather filter and it is impossible to keep the engine bay clean, oil everywhere. I would highly suggest getting or building an oil catch can. they look cool and are 100% functional. double win

 

[and1chewy]

i was actually leary of the whole setup when i read it since there is oil flowing through the valve cover an all. unless i read wrong which is alway a possiblity.

 

[Paching]

There's no oil pressure flowing through that hose, just gasses with some residual oil from blowby.

 

[and1chewy]

yea but still leaky and can cause a mess as ive read i few times over.

 

[Paching]

That's why we recommended the installation of a catch can and not a breather

Catch cans are way bettter for sure rather than an air breather!!

 

[ilco187]

The proper way. http://www.dsmtuners.com/forums/articles-engine-fuel/366890-4g63t-pcv-system.html

I really doubt you will notice any difference regarding horsepower or anything.

You will have to switch it back how it was every time you get the car inspected, which can be a real pain. At least here in Virginia, it's instant fail.

To answer the question "how do you plug the hole in the air snorkel". Do not paint something and stick it in there like you imagined. You don't want paint in your engine. However, if you can tightly plug it with something you know is weatherproof and can't be pulled in, then by all means.

But you can buy plugs for that.

It's hollowed out inside, and it fits tightly on the end of a vacuum nipple. Don't get cheap ones with the seam around the top, because the tip will then be a weak point - after some time, it can give way and get sucked into your turbo - especially if it was a tight fit and you were really wrangling it on there, creating a flaw (EDIT: It would probably just fall off, creating an unfiltered and unmetered hole - a path of least resistance).

Silicone plugs would be best. You could put a bit of some kind of moisture on the nipple to help put on these kind of connections, but just use a trace.

In my opinion, it's a good idea to buy a pack which includes various sizes if you plan on working with a turbo vehicle. There are plenty of vacuum connections in our cars.

yea i think i decided against the filter a while ago after a few posts like i said i seen it in the build guides and was interested.

No problem, I like to be thorough because other people are bound to be interested. For clarification, here is a better example of the plugs with seams around the top.

You must be logged in to view this image or video.

Avoid these, I've had the top come off of one before (right at the seam). Who knows how long I just had an open hole in my intake system. One day I simply noticed it was like that.

i understand. i read the article that nasty dream posted and like alot of things on our dsms unless you plan on major modding (which i dont) you should try to keep things as close to the stock system as possible i.e. the pcv system isnt atmosphericly vented and shouldnt be switched to such a system. Like the age old question of BOVs.

EH? You must have me confused ...with myself? Well, I didn't post any article.

 

[and1chewy]

your right it was ilco187. i apologize. didnt look back far enough.

To be honest, I don't know anything about air filters and I have really dumb question to prove it. Let me start out by saying that I am a girl and I know nothing about cars. For the past month my husband has been talking about how his car needs a new air filter and I'm going to surprise him by buying one and installing it in his truck! Step one was to start searching for where to buy them. I looked online and found this website that sells honeywell filters filters. I have no idea if these filters are the same kind of filters that go in vehicles. Can someone tell me if there is a difference between house air filters and car air filters? Does that place have the car kind? My second question is how to install them into the truck? Seriously, thank you so much for any help! Try to hurry with your answers, I want to have this done by this weekend!

Go to Advance Auto. They'll pull it and install it for you if you bring the truck to them and bat your eyes at one of the neanderthals behind the counter.

 

[ljacobs13]

Ok! I will give that a try!

I removed your link. I smell spammer.

Don't put it back up.
