B_CRUZ!

I looked through 3 dozen thread and most of them with dead pictures/links.

I want to make a DIY with a coke bottle and I just want to catch the oil. NOT drain it back to the block.

Can I just route the pcv hose to a coke bottle and leave it at that?

I want to see other peoples coke bottle/oil bottle/ATE super blue botlle set up.

thanks in advance.

your ghetto.

you can at least attempt to use something from home depot that is stainless steal like a chrome oversized liquid hand soap holder. anyway, good luck with your DIY. make sure to post pictures.

Yeah I'll figure out the actual can out later. I am trying to figure out whether or not I should leave the pcv intact since it won't be connected to the intake manifold. No suction equals no open valve right?

So should I take remove the valve and just route it to a vented can?

lol, i haven't the slightest idea. i was just giving an idea of using something less "ghetto". my buddy used a chrome hand soap container for his radiator overflow tank so i was just passin' on the idea.

just go to home depot and buy a $25 air compressor filter and be done with it.



i added the green dish scrubber for more filtration.

If you don't remove the PCV valve, most blowby will exit out of the valve cover because that's the route with the least resistance.

okay but what I am asking is :


would the line from the pcv valve connected to a vented can work?


plug up the intake manifold and be done with it or is there something else I should do?

I don't want that oil going back into the block.

heres a writeup of my catch can installation. i also modified the intake and removed the charcoal canister. ive since crashed and given away that car, but i did note 3-4 extra mpg improvement with this setup on the last few tankfuls i got.

you can see how i plugged the intake. thats just a bolt with a button hex head.

thank you very much sir. that was EXACTLY what I was looking for.

if i were u i'd just go buy those E bay stuff..

saves your time and pain in the *** trying to figure **** out.

how do you figure? I don't want to recirculate the oil back into the motor. I don't see how buying a generic ebay catch can would help me figure it out better.

hadehatch

a catch can wont recirculate the oil back into the block... thats the whole point.

A friend of mine used an external oil filter from home depot.. You have to connect one side of it to the intake and the other side to the valve cover...

The vacuum will suck the vapors and oil out, the oil will get stuck in the can, and thats why they call it a catch can.

Hope that helps..

Tyson

if you still hooked it back up from the catch can to the intake, where is the air that enters the intake manifold coming from? a chamber (the catch can) full of oil vapor and condensed oil ! now how the hell can you say theres no more oil going into the intake manifold? less, yes. but its not eliminated. so whats the point?

Ok well if you have a filter element it would trap all the oil.. thats what my buddy did anyway.

The external oil filter had a cotton element in it..

Try it, i dont think it could hurt, and the amount of vapors getting through to the engine will be almost zero.

That is what I did. But it's not only oil vapor what is coming out of the engine block. It's exhaust gas (blowby from combustion chamber) that is coming out and going in the intake. You don't want that either.

hadehatch

The only way i can think of to avoid the blowby going back into the engine is to not use the engine vacuum to pull this stuff out of the block.

It would get a bit complicated but you would have to use a seperate vacuum source, such as a electric pump or something like that, to suck out all the crap out of the block.

I didn't know you were concerned with the minimal blowby that enters the chamber, I could see how this could be a problem if you had bad rings, but on an engine that runs well it shouldn't make a noticable difference.

DutchITR1689

I don't need a vacuum source. I just let it vent to outside the engine.

Sounds logical, but isn't the idea to catch the oil and not filter it to the track?

You can catch it, but you don't have to. Oil is not dripping out of those hoses, it's oil vapor, so it's almost invisible.

Utilitarian

Ok. I read that they were to keep the track clean, but I guess that's with older cars.

The block is circulating because of the pistons moving up and down. This creates pressure inside the block. This pressure is relieved by the use of a pcv system. this uses the intake manifolds vaccum to draw the pressure out through the one way pcv valve, while fresh air enters the valve cover from your intake tube. The main problem is that this pressurized air contains oil vapor which is normaly collects on the back your intake valves. The catch can is supposed to cause the oil vapor to condense and collect in the bottom of the can before entering the manifold. If you don't have it venting into the intake manifold, there is no suction to draw out the large amount of pressure, and you need to add bigger/multiple lines like this...


It is also necisarry to add sufficent amounts of incoming air from your intake tube to help make the whole system work better at high rpms. This can be accomplished by the addition of a slash cut tube that extends into your intake tube where your valve cover connects to the intake like this...


I hope this helps

You don't need the intake to suck it out. It will come out of the engine block itself if the pressure is greater than the outside air pressure.

And I don't need extra holes in the valve cover, because with my setup the blowby is coming out though the stock breather (black box below intake)) AND the stock valve cover hole. That's more than enough. The PCV valve is removed so that it doesn't act like a resistance for the blowby gasses in the engine block.

Tyson

wow i pity you and your ignorance that has left you with a mutilated valvecover. what you did to route your "catch" is totally ******* senseless. how does opening TWO extra passages circulate anything with your setup? do you even understand positive and negative pressure flow?


how do you get from this: (which is correct)

totally ******* opposite in explanation. if you actually understood the **** that comes out of your mouth, youd realize youre totally contradicting yourself.

ppl like you who post dumb pictures and bad sketches are the reason everyones confused about a simple catch can.
