HELP. Turbo leak!
 

Ok so i have a b20VTEC in my integra with a junk yard peiced toghter "home made" kit.

I have been burning oil like crazy brand new motor 1,450 miles on it everything internal was machined or new

my breather hose that goes from the valve cover to the intake its not hooked up to anything yet and its just steaming out i noticed just a few days ago white smoke is shooting thru at idle and even more when i give it throttle. I did have bad valve cover gaskets but I just replaced them today. Anyways I noticed everytime I would put my finger on the end of the breather hose oil would just start spilling to the ground from the top of the oil return.

any suggestions? do you guys think its leaking because the crankcase pressure isnt being released? what should I do?

heres a pic to more clarify what im talking about

Re: HELP. Turbo leak!
 

when you say its conected to your "intake" do you mean your intake tract or intake manifold, or your intake (pre-turbo).

Re: HELP. Turbo leak!
 

the hose that I have that noramlly goes from valve cover to THE intake. not intake manifold its not connected to anything because i was in a later time going to re route a pcv system that goes from the cover to the induction side of the turbo.

basically in short im shooting white smoke out of my valve cover and when i plug it up oil starts squirting from the oil return. (its siliconed theres no gasket) that CAN be a problem..

A: Go with a Greddy kit next time. Home Made setups are stupid.

P.S. There is no gasket for the valve cover? You're putting in too much wrench time.

lol did you really just say that there isnt a gasket for valve cover? rofl!

Re: HELP. Turbo leak!
 

Still don't make any sense and I read it like 5 times.

Re: HELP. Turbo leak!
 

its very simple. do you know what a B series valve cover looks like for a honda?

if you do, theres a opening on the valve cover for the pcv. on a stock honda theres a hose that goes from there to intake (to relieve the pressure build up in the motor)

ok I have white smoke coming from that opening in the valve cover and when i plug it up oil starts dripping more and more as pressure builds up.

the area in red iin the pic is wheres its coming from. the top side of the hose where the oil returns to the pan

Never mind, I see now. You blew your JDM motah.


Next time you find your way into a bulletproof ZC from Topgun Motoring out of Palmdale, Ca.

Re: HELP. Turbo leak!
 

First thing do you understand what a turbo does? You are connecting a boost line to you valve cover! thats putting a positive pressure on your motor How much boost where you running into it. I wanna see you launch your dipstick like a ------- rocket. Block that line off and put a breather on the valve cover

Re: HELP. Turbo leak!
 

you've got broken ringlands and so you're pressurizing your crankcase. When you plug the vent for the crankcase (hose coming off your valve cover) the only way your pressure can escape is making an exit at your drain line return. It takes a little oil with it hence the oil leak.

Edit: just read that you have a new engine. Looks like something is not so great with that nwe engine if you have a ton of white smoke blowby coming out the breather

Re: HELP. Turbo leak!
 

omg LOL at the I blew my motor i think you have no brain, leave thread

and NO im not putting positive pressure into my valve cover I very much understand how a turbo works.



I think my problem is im nto releasing enough pressure I need to get more air sucked out of the valce cover

Re: HELP. Turbo leak!
 

Good idea. It should be acting like a rotary with blown seals pretty soon. Let me contact Tom. One of those blocks is like 6-7 gees. I will get one reserved for you today.

Re: HELP. Turbo leak!
 

Highly doubting this one, brand new OEM rings only 1k on the motor and I have not yet put a fuel pump so my motor has not seen any major boost. Its only seen about 2-3 psi.

Re: HELP. Turbo leak!
 

Just keep reving it. It may just clear it self out.

Re: HELP. Turbo leak!
 

Who built this engine, did they know anything about assembling engines? Or did you buy it 'freshly rebuilt'?

Re: HELP. Turbo leak!
 

b20's are only good for 5psi max. Your boost gauge at certain altitudes measures pressure incorrectly sometimes.

Re: HELP. Turbo leak!
 

Its getting better cuz my motor was so clogged up wirh oil.


and this rebuilt engine was rebuilt by me and a honda/acura tech ONLY with 20 years expirence. a good friend of mine also

Re: HELP. Turbo leak!
 

no Im making less then 2-3 psi i have leaks all over the place and ---- and by the shitty way it pulls i can easily tell its not over 3 psi. it CANT be the rings.

ill bet my balls it cant.. rings with 1k on them and only 3 psi of boost OEM rings..

Re: HELP. Turbo leak!
 

Ton of blowby, ton of oil consumption. hmmm?


I'd bet a compression and leakdown test will make someone frown

WTF? are you serious you need to get that ---- outta there. It will ---- everything up having oil in your engine

Re: HELP. Turbo leak!
 

you guys arnt reading.... If i had a shitload of smoke coming out of my exhaust I would shut the ---- up and go rebuild again. but this is odd its coming through my valve cover.

Re: HELP. Turbo leak!
 

You can buy this thing called a compression tester at most automotive stores. They are about 30 Dollars, check one out and holla back nigga whoop whoop.

Re: HELP. Turbo leak!
 

this was froma bad valve cover gasket got oil all all in my cylinders (lots of it, like lots lots lots) and i think some oil still might be burning off

my plugs were comppletly soaked in oil. when i took the plugs out oil was about a quarter way filling up in the head. the valve cover gaskets were completly ---- theres even oil in the plug wires...

Re: HELP. Turbo leak!
 

i wont bother to check compression ill do a leak down test when i get to the shop

Re: HELP. Turbo leak!
 

ok you cover up the hose off of the valve cover.. we get that...

where does the oil come out at exactly???

they are telling you ringlands because of the excessive blow-by that you are describing... we need to know, where the oil comes out of when you cover up the breather hole

Re: HELP. Turbo leak!
 

ok.. i just read it again and he said that oil is coming out of the turbo oil return, i think thats correct.... what was the ring gap??? thats blow-by. you are pressurising the oil system.... either busted ringlands or a really fucked up piston ring gap. i really hope that you installed the rings right and clocked each one

Re: HELP. Turbo leak!
 

it looks like its dripping out of the oil return.

BUT it wouldnt take much for it to drip out of there because its a shitty old silicone seal that i have going out there.. there isnt any kinda gasket

Re: HELP. Turbo leak!
 

you're not reading, how are you going to get pressure and white smoke in your crankcase at idle? (if you hook a vac line up wrong during boost you can pressurize your crankcase also but I doubt you're sticking your finger over a hose under your hood while driving)

You've left with nothing but combustion escaping the cylinder via means it should not be doing, via headgasket or more likely through the piston or rings etc. headgasket would hit the water jacket first and cause overheating issues before it reaches the crankcase.

So get off the internet if you know what's wrong with your car and fix it, stop asking what's wrong if you know everything. Or go and do a compression test and leakdown test and see how you're getting pressure in wrong parts of your 'new' engine.

You're engine should not be getting a ton of blowby unless maybe it was built with huge tolerances for huge power, or something is not right. I'm not schooled on how a huge power build behaves, but none of my honda engines had excessive smoke from the breather until I cracked a ringland or outright broke a piston.

Re: HELP. Turbo leak!
 

But you said it gets worse when you plug the breather. All that oil and ---- on your plugs and in your cylinders and around your plug wires will still not affect the smoke coming out of your breather. It will cause smoke out your exhaust etc.

Re: HELP. Turbo leak!
 

well then id probably believe that i got a bent vallve maybe

Re: HELP. Turbo leak!
 

well there you go. a pressurized oil system... damn did you install 75mm pistons in a B series on a quest for 1000HP

Re: HELP. Turbo leak!
 

Well its kinda obvious why im leaking out the oil return just leaks down from gravity. it seals it when its normal but when it become pressurized it leaks (that would be normal for me) consider the fact that its just shittly siiconed on there

Re: HELP. Turbo leak!
 

should of bought a stealthmode oil line kit.....

Re: HELP. Turbo leak!
 

too many tickets and bills. I always make it work out in the end after a lil bit of struggle.

I payed 200 bucks for the main parts for the kit and created fittings and hoses etc..

its all working out just watned to see what you guys had to say. thanks for your thoughts everyone i appreciate it!

Re: HELP. Turbo leak!
 

Jesus I'm done here, I guess I must not have a brain.

Re: HELP. Turbo leak!
 

You prolly do but how the ---- can smoke get passed the valves unless its bent or something?

dur

Re: HELP. Turbo leak!
 

problem solved.

exactly what i was thinking

What you need is a oil catch can. Found a quote from an old thread for ya:

"On a boosted Honda, the PCV Valve system is pointless when there is no vacuum in the manifold or positive pressure.

1. The valve cover breather filter is harmful in a boosted Honda because all that pressure in the crankcase is trying to force itself out of the little hole in the valve cover. This may cause cam seals or such to blow out quick. The best way to overcome this is to drill two more holes in the front of the valve cover and add fittings/hoses to let this pressure escape faster. Or on the back of the block, there are two plugs that you can undo and put in a brass barbed fitting and run hoses to a catchcan. (Either run it open or close loop)

2. The stock PCV system allows for both reliability (less wear on the seals) and serves as an emissions purposes (Lets the blow by gases flow back into the system so the air doesn't get polluted). As for performance, at WOT the stock PCV doesn't do anything put spit out blow by gases" - member Ri5e








you guys lose talking all this ---- about the builder and going off n saying this n that

Re: HELP. Turbo leak!
 

you shouldnt be boosting cars..

what management are you running?
what injectors?
what turbo?


i really hope you blow your ---- noob.....

should of did research before boosting your car....

dont be hating on my ------..... most of us on here can put your little honda technician that dont know ---- down the drain and curl up in the fetal position and cry...

lmao yeah. good insult bud!
