I have to change my results on doing what Joecar did. I still have oil being sucked into the intake. I pulled the line off the intake and oil was dripping off. Then I unscrewed the oil cap and oil was dripping off the cap. When summer comes around I might have to delete the pcv to avoid lot of pinging.

 

What would be the advantage of removing the pvc system, pluging it, and adding a breather over just adding a catch can? Which is better and could either cause problems? Thanks

 

well ive sense added a craftsman catch can and its working well no diffrence in the ay the car runs but it sran fine before but wow is it catching a ton of oil. so im happy its just not in the intake. i may still try breathers this summer i dunno i dont see how it would build up and not vent pressure with an open hole basically only restricted by a light filter(breather) it can only let off as much pressure as it builds i supose

 

I drove my car to Virgina a few weeks ago, about 1000 miles, and I used an entire quart of oil (.33 each fill up). I usually drive my car about 1000 miles a month, so the oil consumption was not so evident. I looked for a quick fix to at least get me back to FL without going through another quart so quickly, and I tried this:

My consumption dropped to less than .25 of a quart on the drive back to FL. I was impressed, plus it was cheap and easy!

 

another vote for the write up

 

so for those of you that have taken off your PCV and just added a breather filter to the passenger side, have you had any problems at all with it? Im really thinking about doing this, but seems that everyone has a different opinion. Id like to hear more from people that have done it.

 

I'm trying a higher weight oil now with the Joecar mod. I just changed my oil with 4.5 quarts 0w40 and 1 15w50. So far when checking the oil cap it's dry. Only time will tell because every other thing I tried to stop oil vapor would work for a couple hundred miles and then not work.

 

I should have mentioned (but I wasn't sure if it had any influence) that I run 15w50 and 10w30 mixed 2:4 or 3:3 or if it's a hot summer 6:0.

If you can find a way to put a baffle on the underside of the oil cap and get it to stay attached without dropping onto the head, then let me know; I think that may be the next step in the "PCV valve in oil cap" mod (i.e. cap with baffle so path to PCV valve is not direct).

 

Man, Ive read through all 6 pages of this & there is defiantly some good info in here. So anohter vote for a sticky.

Now, Ive noticed that the same question is still being asked/debated over & over again. "Anyone try a sigle breather & caping the rest?" Maybe not word for word but you get the idea. I had this setup on my stock motor for about 10,000mi without any problem. After I spun a bearing & installed the 408ci I switched back to the stock PCV system mainly because I thought maybe that the oil consumption I had prior to the new motor was from my stocker being worn out. But it wasnt.

Basically what I did was remove the PCV lines from the back of the drivers/pass side head & intake. I capped off the intake where the PCV line connected just behind/below the TB & the pass side valve cover on the rear where the line also connected. You can buy little rubber caps from advance auto parts.

On the drivers side rear well I took a rubber insert used on test tubes & just plugged up the hole. ( sorry I work at a Lab)

I left the line that goes from the front of the pass side valve cover to the TB, mainly for fresh air.

Now on the oil filler neck, at a local speed shot they had K&N one way breathers. $14 They would allow air out, but not back in. Make sense? Any breather want work, the car will not idle it you stick a just any breather on the oil filler neck. (accidently grabbed the wrong one first)

Thats all I had done. No problems, no oil in the intake runners.

Let me know if anythinks this isnt correct or will cause problems.

 

I have a stock motor just lid and catback and im thinking about deleting the pcv and just running a breather, i have a small hole in the hose that connects to the intake anyway. Will this have any negative effects on my motor in the long run, or should i just go with the LS6 PCV.

 

Sorry to threadjack, but does anyone have the rubber PCV hose theyre willing to let go of? I lost mine, and I want to try a homegrown LS6 PCV mod. Thanks...

 

Ls6 Conversoin Is Easy And Proper Fix

 

Mabye You Should Add Tat To Your List It Is The Proper Way To Fix The Issue
Definately Dont Remove The System Your Oil Life Will Turn To **** **as Has Been Proven On This Forum In The Past**

 

Any breather will work. If your having idling issues then you don't have everything caped

 

No No No No !!!!!

In This Same Discussion A While Back A Few Very Smart People Finally Were Found That Let Us All Know That Removing The Pcv System Will Not Allow For Your Engine To Be Proper Ventlated And Your Oil Will Start Asorbing Motisture

The Pcv Delete Is Only Ment For Race Cars But If You Don't Wanna Change Your Oil Every 1000 Miles Don't Do It

Again I Suggest The Ls6 Pcv Conversion It Aint That Hard And Its Not Really Expensive And For The Best Part It Works 100% No More Goofy Catch Cans Or Breathers

HERES THE SAME DISCUSSION BUT LAST WEEK READ BOTTOM OF PAGE ONE AND PAGE 2

 

So breathers on the rocker covers will allow for unmetered air into the system? Would seem like with a breather, LS6 valley cover and catch can this would allow for the best combo to keep the intake dry and crank case pressure controlled.

 

you wont need a catch can if you have a ls6 valley cover

 

Breathers on the rocker covers will NOT let unmetered air into the system if everything is plugged up right. **** is flowing OUT of the breathers, not in.


Fixed!

The catchcan PCV stuff is all fine and dandy as long as it can keep up. My 120k mile heap had so much blowby it was shooting oil out of the PCV and the fresh air tube even WITH a catchcan.

I have a breather now and no PCV system and it seems to run 10x better than before. I revamped the whole PCV system before the FAST 90 went on and it still got coated in oil, so I said to hell with it.

After the new motor goes in (soon), I'll probably change the oil every 1k miles anyway and it will be retired from it's daily driver duties.

 

The Whole Pcv Delete Is A Bad Idea Besides Its Not That Hard To Just Swap The Valley Cover And Do It Properly Do Quit Rigging It And Just Do It Right And Move On..
