$30 Oil Catch Can, DIY

[Ogredude]

who needs a Cusco, keep your intake clean with an air compressor filter / air dryer,
parts needed:
$26 - 3/8" Husky filter (crappy tire / walmart)
$4 - 3/8" hose fitting connectors
and some teflon tape

after only 500km it has about a teaspoon of oil caught already, crazy eh?

here is a corvette owner who has also done this:

1. Take off engine cover - 4x10mm nuts
2. You have to cut the PCV hose, the one that goes from the back of the vavle cover into the intake manifold near the front. Cut the hose about 4" down from the back, and re-install it the opposite way, now there is room for the compressor filter away from the motor.
3. Install the Hose fitting connectors into each side of the compressor filter, with the teflon tape,
4. install filter. Make sure it is facing the right direction, the air flows down from the valve cover and gets sucked into the intake so the arrows on the compressor filter should be the same direction.
5. The valve cover Intake hose will have to be removed for the install, and be re-installed over top of the exit hose.
Hope you can understand that Jumble, these pics should help a lot.

great work, thanks for the pics on this DIY.

newbie question: what does this help improve?

Edit. Question answered

Weird. This is always an issue on both my supercharged Fords, never thought it would be as bad on this lil 4 banger.

Toyota has had many issues with sludge ..
Google "Toyota sludge" ... select images, you'll see a wide variety of damage caused by sludge.
Go to this link and read about it http://yotarepair.com/Sludge_Zone.html
Now I'm not saying that Toyota hasn't solved the problem, but I agree with OgreDude's solution, better safe then sorry.
The oil that is now captured was destined to go into the intake and burned off, so worst case now is that we save a bit of pollution from occurring.

[uncleyaris]

sludge can lead to other probs. I have heard that the burn off causes emission ; pcv, sensors to wear faster.

Here is the one I made. Total cost $17.44.

any oil that escapes pass the pcv will make it into the intake manifold. the catch can is there to clean the oil off of the airwaves and keep your intake manifold clean.

definitely an easy/good thing to do to your engine.

So it keeps oil from the intake manifold...so what? How is this good? The oil simply gets burned, right? How is this so bad? Sorry if I sounds ignorant, but perhaps someone can enlighten me?

Nice DIY, seems very easy

Pavel....I'll try to answer this, the intake manifolds purpose is to flow air as efficiently as possible, with excess oil getting in the intake it will slowly get an oily/sludgy buildup. Since the manufacturer isn't too concerned, it will probably not be a problem for 99.9% of car owners.....just a matter of how concerned a person is. (Could be more to it but think this is the main idea.)

[Jerkratt]

but wouldn't putting this there decrease the air flow??? cause of the shrinking of the airway?

[churp]

Cars never used to have this until EPA got into things. The crankcase air used to be vented to the open air...and your intake only sucked clean air thru the air cleaner. These filters are low restriction and shouldn't hamper performance or the environment.

[Ogredude]

airflow? aint really an issue, the filter is not restrictive, you can easily breath through it if thats what your wondering

No.

[Mr.Yaris]

If this was really a problem, you'd see Toyota do something about it. It's not a Toyota, but when I pulled off my Camaro's intake manifold to port match the intake ports to my new high-flow cylinder heads, the engine had 120k miles on it, and it was about 9 or 10 years old when I pulled it off. There was very little, if any oil buildup, and no "sludge" to be found. Cylinder walls and piston tops looked like new (pays to regularly clean your fuel system with every oil change...)

Point is, I didn't have it on that car, and I'm sure it isn't as "clean" of a running motor as the Yaris is. Just my 2 cents, do whatever makes you feel better about your car. As for me, I'm not gonna sweat it...

Ogredude,

Thank you for the DIY! It gave me the confidence to do this for myself.

I got all the parts at Home Depot, and more of them than you listed due to the lower valve of the Husky filters not closing worth a crap, but I came in at just under $20.

1) Small Husky fuel filter: $12
2) 2 3/8" pipe fittings: $4
3) Drip sprinkler: $1.50
4) Sprinkler goof plugs: $2

Total: $19.50

The drip sprinkler was the cheapest way to get a few millimeters of the 150 PSI drip hose that would fit the nipple on the bottom of the filter, and a goof plug caps it off. Other than that my install was identical to yours.
