Intake Pipe Question

[burgO.]

Hey guys,

Just bought an intake pipe off a bloke on here and it has no entry for the bov (which is fine becuz i run no bov) but i realised there is another feed that goes intake the stock intake pipe which appears to be for oil? (i really am unsure of what its for), the intake pipe i bought also doesn't have the entry for it, just wondering whether i should get a hole welded in or whether i can just bloke that pipe up? pretty keen on an answer tonight so i'll know whether to put it all back together for work tomorrow, i've attached pics

Thanks in advance for any help

u run no BOV?.and fresh air in crank will make oil last 4 times as long that all i know.only drag racers or d1 guys would not run crankcase vent (and some tests have proven it less stress on cranks turning)(and blowbye on rings)and with no crankcase vent u will deff need to change oil every 2000kms or less

and your car look daily driven so i would vent crankcase IMO

soz for the stupid question but what does that mean lol? is the crank case the pipe that goes over the rocker cover? so i just take the pipe off and leave it open(the one goin to the intake)? is it generally the thing to do? any down sides etc?

When i say i run no bov i mean the bov is blanked off (flutter etc)

[cosworth1971]

why wud u blank the bov off for?bov makes it boost faster!

and to run without the crankcase ventalation there wud be stupid and fatal that intake is for someone who changes oil every 1000 kms do you want that and more wear?

u need that pipe to make u engine last a long time!eg 100000kms vs 300000

yes u can run without it and leave it open but thats very bodgie i think!

with my rally car and webbers i run without but thats a full race car

[burgO.]

oh so venting the crank case means actually having that pipe tee'd into the intake pipe, im with ya

[cosworth1971]

yes that pipe might be ok for someone who does under 5000kms a year and changes oil ever 3 months.like a show car. but personally id like a pipe for my crank vent( as air makes ur oil stay clean longer)

You'll just have to drill a hole in the new intake pipe and weld on a bit of pipe when the original bov vents back in, and use a bit of heater hose to connect intake pipe to bov vent pipe.

[cosworth1971]

yeah !wont hurt

I want someone elses view on this as the motor has a pvc valve near the left of that (near intake manifold/fuel reg)so maybe that enough?

so maybe u can run without?its just a question on how quick you oil get dirty as less air mean dirty quicker

Ive only had my car for 2 years but im a good old school motorsporter

you should try without?but then u may need oil catch can because oil may splash out those holes on the top of the motor?( i mean a little oil no heaps)but enough to be anoying.

i need more skyline expierence here guys

so dont drill yet mate

[burgO.]

I'm not sure what you mean BAMR33, i wont need an inlet for my bov, only the other inlet which cosworth said was to vent the crank case

Can i the crank case vent be tee'd up to an oil catch can? because that might be an easier option rather than getting a inlet welded it

[cosworth1971]

i dont know mate as mine is fairly stock but that sounds good and ideal,wait for nizmoid or someone with proven knowledge to post ere mate

[burgO.]

Yeah cool, worst comes to worst do you think it would be ok to put the new pipe on and block the venting hole up for a week until i can get a catch can or an inlet welded? i plan to do another oil change in 1000-2000kms anyways

I only read the first bit of your sentence. But for your oil breather just disconnect it at the top bit of hose and put on a small oil breather filter thing, monza makes them and they cost like $10 at supercheap, look stock too. If your car is highly modified and having oil issues a catch can is necessary until you fix it.

[cosworth1971]

what ever u do dont block it up but in older motors u can run a hose(the hose that goes to your intake)(just make it longer?) to a coke can inside ur engine bay as a temp as it will prob get some oil in it and a catch can should go straight on maybe with over the counter fittings and keep ur intake as is...but like i said im new to theses motors but not horsepower :sorcerer:

so wait mate for someone whos done it to post!

[R34NRG]

was in the same situation, made my own intake pipe but forgot about the oil hole.

bought a oil breather(which is illegal) until i could drill a hole into the intake pipe.

wat ever u do dont leave it unplugged, u dont want oil drippn onto places that are hot....trust me lol

[burgO.]

R34NRG - do you think i should plug it up then? or have something to drip it into, cause i really need my car to get to work tmoz (only about 5km) and i really dont want to take everything apart again

just get a oil breather man.....plug it up with that....and find someone who can modify ur intake, then go to autobarn and buy a long rubber hose....lead it in...bloody easy man.

it woudl seriously cost u like 25 bux.

a nice steak at la pochetta but theres always next week.

fark does anyone else love their steak? mushroom sauce baby...droolz

mmm. The way mine is set up is to have the hose run to the start of my pod filter, where there is a hole drilled in the rubber (where the pod connects to your intake pipe) and a nipple sealed in. Its alot easier than to modify your intake pipe.

although mine is running a oil catch set up, same deal applies as to where you can tap that breather too

You stock intake will have two hoses going into it, one is for the return of the stock bov and since you aren't running it you wont need that. The other is for the crankcase ventilation and thats the hoses that are running over your rocker cover. You cant block this ventilation off, you need it otherwise you'll drive down the street and your dipstick will pop out and make a nice mess.

You have a couple of options:

1. Modify your new inlet to be able to take the ventilation hose (and this has to be done BEFORE the afm)

2. Get a catch can and run the ventilation hose to that instead, but thats just another shiney can that will stand out in your engine bay and if you get pulled over will get you defected by a retard cop that doesnt know the difference between a bov and pod...

I would just do option 1, but what ever you do dont block that hose off and dont just put one of those "monza" filters on it, the ventilation hose can carry a bit of oil especially when your on full boost and the last thing you want is oil being sprayed in your engine bay, right near a nice hot exhaust manifold.

i'm still running stock intake pipe, airbox, blow off valve and crank case ventilation system.

the air flow meter bolts right up to the airbox. both the bov and the crank case are plumbed in well AFTER the air flow meter

this image sorta shows how far down the plumbed in lines are. the airflow meter is off the photo!

it makes logical sense that you want the bov air going back through the afm. but definitely not oil.

[skybarge]

I'd go for a catch can if i was you, pull out stubs where the current pipes connect to, then get two new screw in fittings, can't remember the size, maybe just over 1/2" BSP? you'll have to check, block the PCV valve off with a blanking screw and remove it from the manifold

Then mount the catch can somewhere in the engine bay and run two lines to it

That way you'll be setup for any track work and driving on the street(incase you somehow lose your oil through the breathers...

I think for track(well at least in NZ) your catch can must be equal or greater than your engine, for street I used to just use a 1L one, never had any problems

The coke bottle trick also works, but it's terrible ghetto and I'm sure a cop would defect you for it
