I have tried searching this topic without success. I am hoping that someone could shed some light as to when the stock PCV system becomes inadaquate and/or overworked. I currently have a 1.8L LSV w/12.5 to 1 compression making just over 200whp. Is the stock PCV system w/oem PCV valve and black breather box fine for my current power level and compression? When would an upgraded system be necessary?

No one has any input?

when the oil pressure in the block pushes your dip stick out on the dyno

honestly just upgrade that **** asap....its easier to work on...and for my car it's not necessary...**** i dont even run a cat....

when i was only making 198whp i upgraded.. hell that was the first mod i did and i noticed a difference.
I pluged up the hole where the black box went with a z10 block plug, i then got 14mm allen wrench from autzone and put new plugs into the back of the block with nipples and ran those to a catch can, car runs smoother, faster, and hardly burns any oil because of less crank case pressure..
Search the archieves for catch can in search it'll come up under forced induction i think.

anyone have any diagrams on what they did/how they did it?

IntegraType-R

search it isn't hard.

just get the endyn breather setup which comes with the 2 plugs with nipples on them and a ventilated catch can

yes, just do a search and get to reading. there is probably 1500 pages of random information on this topic. i do beleive there is a 17pg post in the fabrication section right now. when your done reading go lay in bed and think about 1 of the 15 different setups you saw and their corresponding reviews, sleep on it, wake up, read it all again, repeat. after a few days of this bite the bullet and pull out the visa and give summit a call and spend a few hundred dollars on AN fittings and hoses, and seriously debate buying a T1 catch can. there are also alot of kits out there, edyne, T1, etc. how much do you want to pay for this?

jeffy

oh yeah, just search the archives for catch can

I’ve been thinking about this for a while and I would like your input on this.

With the black breather box still hooked up can’t you just TAKE OUT the pcv and run a hose from the breather box to a higher location and just vent the pressure to the atmosphere?

I don’t see a difference in the method mentioned above and the catch can method. Logically, it should work the same.
Correct me if I’m wrong but, if you’re doing the catch can method aren’t you basically running hoses from the block (or head) to another “breather box” that’s set aside somewhere else?

can u just run the fittings from the head instead of theblock?

i dont completely understand your question but if youre asking if you can vent the crank case pressure from the head, the answer is yes.

sorry, i was just asking, if you can just vent from the head instead of the block, i had my turbo car running from the block before

What about leaving the stock PCV in place and adding one valve cover vent to a catch can? I have been thinking about adding a -8AN fitting to the front of my valve cover to relieve any of the excess pressure. Would this work or do I have to block off the oem setup? Thanks for the help so far guys...

Imo, that would defeat the purpose of adding an oil catch can if you’re still going to be feeding oil vapors from the stock pcv system into the motor.

jeffy

it has been said exactly like this in another thread, 1 is better than none! def. adding any extra ventilation will help. the best setup possibe is to vent 2 from the valve cover and 2 from the block. having just the cover vented helps but you will still have alot of pressure in the block as all of it cannot be removed through the oil drainback passages in the head alone. the factory system is pulling the pressure out through the block for the best effectiveness and another backup vent on the back of the VC. best example for the amount of pressure in your engine, start the car and let it idle, now go to your engine and pull your oil filler cap off and put your hand over the opening. that pulsing strong air forcing its way out is the crank case pressure you are trying to eliminate. you can put together the back of the block setup using factory parts and a few other items from lowes/homedepot if you are creative enough. might not be the best looking/perofrming setup but itll work ok if you are on a budget. the edyne kit is pretty decent despite alot of people calling it garbage, and it only costs like 100$ for the kit, all inclusive. like i said before there are alot of ways to do it, cost effectiveness and your particular setup will play major roles in which way you should go. so many pages have been written on this topic its crazy.

i have one running off the back of the block for now....i will be adding a second can to the front of the valve cover before i hit the dyno again.

The_Head

Here is what was done to mine. It's a little overkill for an All-Motor setup I think.

dinko

similar to mine except i dont use expensive *** braided lines...i agree they do look nice!!!

old picture....its sold already bought a newer EJ6 shell, using same motor, suspension, wheels though

grjp1988

with the endyn kit do you have to remove any old stuff and also do you have to drill any new holes?

in other words do you just buy it and install with no drilling? aka bolt on?

vinuneuro

I've read in the past more than once, that the Endyn system is prone to condensation, which then ends up in the oil.

b20beast978

contrary to your beliefs, many people have had great expriences with the endyne/catch can combo to maximize crank ventilation.

dinko

hows the condensation end up back in the oil if there's no drain back into the motor? the can is there for the gases to "escape" and trap any nasty *** oil that's usually with it...you manually drain the catch can every so often (usually before a track day and after) after you run your car pretty hard, leave it running and pop the hood....go by the catch can and get a big wiff of that nasty *** oil! hah. sometimes you can even see hot *** gasses escaping form there.

*i guess if you don't want condensation...which i still dont get how there is any (please explain) just drain the catch can more often?

the only time ive ever head of people having problems is because their motor/rings are **** and during a quarter mile run the whole can would fill up and overflow.
