Oil Catch Cans// Worth it??

[impulsive]

Was wandering through Supercrap today and noticed a special on Oil Catch Cans, thought it would look nice in the engine bay however is there any benefit to it, is it worth the show?

I have been led to believe it aids in keeping the manifold cleaner..

"Oil in a manifold or cylinder will reduce octane and in extreme cases cause detonation. By filtering this airflow, you reduce the oil into the manifold and improve performance (or rather reduce the chance of reduced performance)"

[wortus]

WOFTAM = waste of f***ing time and money. If the engine is in good order there is not much chance of oil getting in via the PCV system.

[impulsive]

Motor is good, so there in no benefit?

[wikky]

I'm not sure if the 6's would benefit like the 8's (I can't see why not though, to whatever extent). Impulsive, what you quoted in your first post is very true.

[MattMarkey]

yeah i've been looking into getting one too. small thing, keep the manifold clean, nice little piece in ur engine bay. even if it doesnt make a difference performance wise, it would still keep it clean.
go for it i reckon..! =)

$69 at Supercheap is the cheapest i can find.. Anyone know how to hook one up?

[Surfwagon]

As wikky said you answered your own question.
BTW for the benefit of wortus the pcv system is designed to work efficiently when the engine is new and driven normally but as soon as you start pushing high revs the PCV system cannot handle the load and some of the blow by is pushed back through the pcv breather inlet hose and into the intake.
I have never pulled down a brand new intake system but when ever I have removed an intake from any car with a few kays on it for modifications the inside is always coated in some form of oil.

My vz only has 60k on it and there is plenty of oil in the intake so going to get one any ideas which pipes to tap into?

[hsv453]

Every car is different even with the same motor. how its treated and been serviced etc
I done some research on here and on us sites and the ls2's do have blow by problems and a catch can does help them.. found little bit of oil in mine on the weekend, thinking of a catch can shortly..

[wattles]

when i pulled my manifold apart to put manifold insulators in the manifold had abit of oil in it, is that bad?

[soop]

I wouldnt be using a catch can from Supercheap. Most of them don't do much aside from divert the oily air for a brief period.

but you could add some steel wool inside it, extend the infeed line below the steel wool and then it works as well as $200 brand name catch can

instead of always been negative soop, why not try been a positive person and have something nice to say

[soop]

Why, when you can by a catch can that does all that from the get go for roughly the same as what you will pay at supercheap???

[immortality]

then by all means, why don't you google a link for us for said catch can

[coasty]

theyre all crap they store a little bit of air pressure and a bit of oil drips in as well. unless your motor is just about stuffed from being flogged you wont see the oil burn. anyway supercheap has 20% off this saturday

have you seen the oil vapour at 6,000rpm in an engine? there are a few youtube vids worth watching.

20% of sat, sounds good

For a healthy street car they are a waste of money. If you do track days and the like there may be some benefit but for the most part it's a wank.

I'll be running one but that's because the Walky throttle bodies don't have an inlet for breathers from rocker covers to hook up to! I have had screw fittings fitted to rocker covers and will run braided lines to catch can. However I will then vent into air box. To keep it legal. As ones with filters on the top are not technically legal. I am trying to look like u give a shit if it's legal lol.

[immortality]

and yet, look at the intake manifold of any high mileage engine and what is full off? how many threads do you see on this forum where the first response is clean the TB and IAC? a basic catch can setup within a legal PCV system eliminates this problem. car/engine manufacturers don't give a damn because these issues occur long after your 100,000km/3year warranty has run out.

I agree. How many threads for cleaning throttle bodies and intake manifiolds are out there; heaps, google it for any commodore and you will find them. They are always talking about how oil vapour in the inlet reduces the effective octane of you fuel.

with a Holden engine you are better running the breather from the valley to help with the windage issues they have. Walky manifolds already have a breather in the valley so i'd use that.

[wattles]

so i should clean the oil out of my manifold? lol
