What's up guys. Last year when i went 12.1 I noticed on one run the dipstick came up a little bit. I'm getting ready to put the car on e85 and a 2.6 and before i do that I'd like to do a breather setup to relieve some crank case pressure. I'm going to do a catch can but seen a lot of turbo lsjs with the cap vented and such. I did a quick search but didn't come up with much. Any ideas or links to buy these parts from? Thanks in advance I would like to do this before running 11s on the 25th

 

I think a lot of guys such as Area47 & Wicked used a vented oil fill cap breather setup (at one time or another) to alleviate additional crank case pressure.

 

Yea that's what ill go with for now and a better setup later on. Guess ill just tap the cap and grab a cheap filter at autozone or something

 

I think either summit or jeggs sells the exact one show in the photo above.

Check them out to.

 

Yea I will thanks I also have a spare cap as well from the shop that came off a motor job i did

 

You could use one of these:

Valve Cover Adapter, AN Valve Cover Adapters: Metco Motorsports

Screws in where your oil cap goes. Attach a line to it and T it into the crankcase recirc line found on the back of the engine. After that is in place you should add a catch can into the mix to keep things clean.

FYI a breather filter will just get oil soaked after a while, but its not bad as a temp solution.

 

Exhaust EVAC, have it on my car and it works great. Despite what people say about it not working, the hose would suction to my hand just at idle.

Plus crankcase vaccuum nets a bit more power.

Just a thought.

 

I just made one of those instead with a barb fitting jb welded into a 7 dollar autozone oil cap. It did something but not a ton. If you really want to get the pressure out this thread has a lot of good info, Additional PCV Ventilation

 

Interesting I have mine vented to air and it gets dirty quick

 

i did notice that when I switch from vented to air to having it tied into my catch can system that it did make my idle better, but I had attributed that to the fact that having the filter on it gave me a huge vac leak and If I closed off my catch can to vac port line that my idle got better as well.

 

Yea this is more of a temp solution for now when I'm running on the strip. I don't run around on 24lbs of boost all the time

 

I have my cap vented with a K&N mini filter on it. It's been like that for about a year now, haven't had to clean the filter since it's still pink and no more dipstick popping out.

 

be very careful hooking the crankcase to full time vacuum, the oil fog is easily sucked out which hurts internal lubrication and will drain the crankcase fairly quickly. had a friend with a civic who ran a vac line from his valve cover to behind the tb, he was going through a half quart of oil a day and eventually span a bearing.

 

I seem to go through less oil with the valve cover port and the oil cap port going to constant vac than I did with a filter in one. There seems to be the same amount in my catch can but much less disappears though other places.

 

I'm just gona put the vented cap on while running at the strip

 

Out of all the runs I've done its only happened once and barely came up.

 

I have one of ^^^ but have been looking into this idea.

Moroso 97800 Check Valve
Moroso 97800 - Moroso Replacement Check Valves - Overview - SummitRacing.com

Moroso 97810 Weld in fitting.
Moroso 97810 - Moroso Replacement Weld-In Nipple Fittings - Overview - SummitRacing.com

But I want to run it in the extra O2 bung installed in my ZZP cat-d dp.

It would be the bung after the cat.



Do you think i would be able to produce enough vacuum to pull the valve cover gases out without using the weld in fitting?

 

 

need to do that but i am lazy

 

more then likley he dident use the baffled portion of the valve cover if you use the baffeled portion that wont happen

 

you should plug the pcv port in the head if you are running an atmosphere vent so your not pulling outside air and creating a lean condition and crank windage can pop the distick also

 

no you wont get the moroso kit it also has the 1 way check valve you need so you wont get exhaust gasses in the engine

 

With the ZZP intake spacer iirc its already blocked off

 

 

nope the hole is there for it alteast on mine it was
