I saw somebody with a mountain dew bottle as a catch can, an I really wanted to do it... I think it is awesome. So I went searching through the forums trying to find the proper way to set up the catch can, but I cannot seem to find what I am looking for which is: an explanation of WHAT lines I need to run TO WHERE, and FROM WHERE if I want to use a mountain dew bottle.

Where does the line from the left side of the valve cover go?

Where does the line from the PCV go?

What do I do with the nipple on the intake manifold that used to go to the PCV? Block it off?

Where can I get a vacuum source to run to the bottle? How can I make sure it doesn't leak? Will the bottle collapse? Thanks.
 
Im not exactly doing the Dew,
but I used a power aid bottle...
It sits snug against the fire wall under the tb zip tied to the fuel lines, or fuel filter or something.

Most will eek at my pcv set up, I know it has its pros and cons, but thats a different story.. But to answer your question, my pcv valve was taken out, and a straight thru fitting with a hose that drops down level with the subframe aimed at the ground is the pcv, and my valve cover breather line goes into the power aid bottle ( thru the top of the closed cap with a hole drilled just big enough to fit the v.c hose ) while another hose goes out the side of the bottle into the intake arm...

I also made sure the bottle was still vented slightly with a second hole on top of the cap so it doesnt build up pressure in the bottle...

My set up doesnt get good crank ventallation at idle due to not having vacuum coming from my intake mani which is blocked off. But a good thing about my set up is that it doesnt blow boost into the valve cover and pressurized the crank case due to a weak leaky factory pcv valve, which at the 20psi I run will leak everytime reguardless of it being new or old... Id rather not pressurize my crankcase.... A properly set up pcv set up with a check valve that does it job on idle, and doesnt leak under boost would be better than my set up.
 
what is this mountain dew catch can theory? im assuming its used to catch fluids dripping from your engine or tranny but where would you put the MD bottle? obviously not under you engine, i dont think...
 
Just buy a catch can stop giving our cars a bad rep...

This has nothing to do with giving out cars a bad rep... Especially if you dont pop the hood at ricer car meets.
Bad rep comes from many other things and certainly not from asking how to do a cheap quick catch can set up for whatever reason need be.
 
A few months back my factory coolant bottle came loose and flew off in some canyon. When I got home and popped my hood I just took a Gatorade bottle (the mouth of a gatorade bottle is the same size as the factory coolant bottle) wrote "Haterade" on the coolant bottle's cap and hose clamped it in place... It actually sturdier than the factory bottle :D
 
You can make a husky catch can by going to Home Depot, get the "Husky" brand Air compressor filter, buy 2 of the copper fittings and either cut your vacuum line or go pick up a couple lengths of vacuum hose. You should be able to find more instructions if you Google Husky catch can.

And to answer gunny11218's question normally oil will come out and go into your intake, the catch can catches the oil that's coming out and keeps it out of your intake system.

LOL are you kidding me.
 
ooh ok, so its oil from the turbo then. gotcha thanks

No, if oil from the turbo is leaking you have much bigger problems. This is for catching atomized oil coming out of the valve cover. It's the little line coming from the passenger's side of the cover that runs into your intake.

I used to have a 20oz Coke bottle as my catch can. It got some laughs but it was pretty trashy. I've since switched to a $3 inline fuel filter and recirculating the air back into my intake.

i used a poweraid bottle for a while then i put a set of total seal rings and havent had a problem with crankpresser yet.
 
I used a white fuel filter for the valve cover. I just installed a Iron Force air compressor filter yesterday through my PCV. I cut removed the vac line from the PCV, put it on one end of the catch can, cut some spare vac line I had lying around and route it on the other end to the PCV. I had enough line to fit it snugly between my throttle body and fuel rail without much bending the line till it cuts off. I'm going to go check it later today to make sure everything is still working.
 
Well, I am still confused as to the setup. So I made this slighty overly detailed picture. If someone would be so kind as to draw in where the lines are supposed to go, I would appreciate it. Or if you could even just tell me.

Excuse my crude drawing.

I believe this is suppose to be the right way to do it. It's a dual catch can system. This is the system I have running in my car except I'm not using a Dew bottle and I didn't put in a check valve.
 
Haha! Don't use the Mnt. Dew bottle for a catch can, use the Husky filter. It's cheap, looks good, and works well. I would only recommend the Gatorade/Dew bottle for a coolant reservoir and even then, just as temporary solution. Autozone sells cheap ass reserviors. A 16-20oz bottle is major overkill for a catch can. I've had my Husky filter in place for about 2,000 miles and there is still not one drop of oil in it. The filter inside is just barely starting to show some black on it.
 
Where you route your catch can to? Valve or PCV? I have something like a Husky's which I installed yesterday. Driving to New York and and then to school got me a bottle cap of oil already.
 
You can see the filter off the side of the valve cover between it and the air intake in my pic above. I just wanted to keep any oil out of the intake pipe, turbo, FMIC. I didn't bother putting one on the PCV, not yet anyhow.
 
Here is the correct way that the catch cans should be set up (you could also figure this out by reading the PCV thread posted earlier here). I have this setup, only I have the Husky filters as catch cans. I have a brass check valve that has NPT fittings on the end and is screwed directly into the Husky filter. I would suggest going with the plastic one mentioned in the PCV thread as the brass one is big, bulky, and heavy. I'm not sure what people's reasons are for going with the Mt. Dew bottle (other than being really cheap).

THAT'S PERFECT... now for anyone else that is reading this, please don't use a pop bottle (although technically, if it's sealed, it'll work). A Husky air compresser filter is like $10 from Home Depot.

Have some class.:cool:
