Why Would Someone Need A Oil Catch Can

[Adz2332]

i tried searching but it only talks of installing etc...

Why would you buy a catch can? what do they do? what benifets do they hace etc etc.

Do you reali NEED one etc

Also jus so i dont post 2 stupid questions, does a bov sound the same if the engines are the same etc or do they sound different from car to car. my mate has a great sounding bov on his 33 so if i buy the same one am i garenteed the same sound as his?

Cheers

With the BOV yes wuill soudn the same, peoples driving styles,boost,FMIC, and spring tension on bov can effect the soudn the car makes however.

Catch can helps eliminate blow by oil being fed back into ur intake alowing a cleaner combustion. Also alows you to monitor if u have excessive blow by issues which is a good indicator of engine health. I think a catch can is a usefull thing IMO.

GEt one just make sur eits hooked up right or u will seal all the crankcase presuure in which is very bad.

but dont purchase those cheap oil catch cans.. They will do you more harm and will cause oil leaks!!

Isnt there more pressure build up in these cheap cans??

Yeah u neeed to make sure ur not using smaller diamter lines than stock, u dont want ot create a restriction too much or it is not good.

You can always drill the can out and use ur own fittings and lines, thats what i have done.

if you do any sort of track work you generally need to run a catch can. I believe anything over 2litre capacity is 3litre catch can.

But for someone lik me who only drives it on the road and only has 200kws at the wheels, should i get one? to be honest i was only looking at one cos of how it looks in the engine bay!!! plz dont hate me!!!; lol

check the inside of you intercooler piping just after the turbo, if it seems clean dont bother just waste ur money on other mods, but if u've got a bit of oil in the pipes put one on

you don't NEED a catch can. assuming your engine is healthy, with or without one you car will run 100% fine.

i have one. i got it for a few reasons:

- IF for some reason you engine develops blow-by, the catch can is there to catch all that oil before it goes into the intake

- having it there doesn't harm the engine in any way in the event of no blow-by (most engines)

- looks good in engine bay

i mean, its not going to stop blow-by from occuring, but it is going to be able to prevent it from making your compressor and intake oil-soaked.

for a boosted engine at higher risk of causing damage... i say why not?

oil in your intake charge can and will induce knock...more so then if it wasnt present. No oil in the intake is good....unless you have uncoated steel piping with rusty insides lol.
