as title my 3 door is fitted with a group a breather system but i think its giving me to much back pressure and im losing pressure up in my head ???
i have my breather pot by my battery tray with one hose going to block under inlet one hose going round to breather tank on inner wing then i have a hose going from the bottom of the breather tank by battery tray into my sump plug hole ??? which is where im confused as although its a 3 door its got a 200 block so i am thinking this should not be there as it should be round on the drivers side of the block ??? am i right in thinking this as i have never seen this set up before and can not understand why it is like this ??? the tank on the inner wing has the vent to atmosphere on the back corner and also the drainage tap underneath can anyone comment on this setup being either right or rong ??? cheers in advance peeps.

rapidcossie

is the catch tank full up?

bailey1

iTrader: (2)

no catch tank does not seem to fill up but i havent had car that long so not to sure if it does or doesnt really but it hasnt even registered any oil in it in a month of use ???

Stavros

why do you think its giving you backpressure? and what do you mean about losing pressure in the head?

A picture tells a thousand words!

sorry guys would put some pics up if i could but dont have any at the min i will try and source some.

well the breather port on the back of the head/rocker cover is blocked off the breather port on the drivers side of the 200 block is still blocked off so the hose that would normaly go into that port is now going into where my sump plug goes ??? if that makes sense lol .

bttt

the sump bung port should be your return feed, it goes below oil level so it doesnt see crankcase pressure, which can stop the oil draining back to the engine.....

JTECH James

iTrader: (13)

you have no turbo damper either...expect broken manifold studs...

bailey1

iTrader: (2)

so you are saying the return from the breather near the battery tray is right being plumbed in to the sump plug hole ??? not the normal location for the breather return on the 200 block on the drivers side of the engine ????

JTECH James

iTrader: (13)

the normal location isnt to good as a return, because its above oil level....when your on boost this acts as a breather, not a return....returning below oil level means it returns all the time.


i have a return below oil level, and i breathe from both block ports...i dont use the rocker cover port.

the normal location is NOT the drivers side...........that is to vent crank case pressure as well. This is on 205 as well as 200 blocks by the way.
oil should be returned at below oil level and requires the sump to be modded OR as in your case if you dont want to mod the sump for this you can use the sump plug.

I believe GGR did your breather system and specify how many sides of the block to breath from depending on your stage of tune.

Also the returning oil below oil level in the sump is dependent on who you speak to

JTECH James

iTrader: (13)

yes, it deffo a can of worms,

mine works real well though

rsnissan

iTrader: (9)

infact here is the link to the GGR site and info on their systems that breath from one side (2port) and both sides (3port) it also mentions connecting to the sump drain.

cheers guys will check out the site now. my only problem with this setup is i just cant understand the theory behind returning crankcase pressure (not oil) to below oil level as there is always oil in the sump and with the hose being in the sumpplug location oil will (in theory be trying to get out while i have crank case pressure trying to go in if that makes sense lol im a ford tech and work along side to masters and both cant understand the reasoning behind it above oil level yes but below it ??? cheers anyway guys for your help

JTECH James

iTrader: (13)

you cant return oil down a pipe that has crankcase pressure coming out the other way.....


returning below oil level stops crankcase pressure coming up the return hose....so oil can drain through it into the sump

bailey1

iTrader: (2)

website checked guys i think my problem now lies elsewhere back to the drawing board .

rsnissan

iTrader: (9)

the crankcase pressure is not going below oil level........it goes to the breather where the oil is separated from the (oil) vapor and the by product (oil) is returned (below oil level) to the sump

rsnissan

iTrader: (9)

BTW you neer really qualified your statement earlier...........why do you think its giving you backpressure? and what do you mean about losing pressure in the head?

JTECH James

iTrader: (13)

what is the prob?

Nash

iTrader: (3)

What sort of price do the 3 port GGR breathers go for new does anyone know?

I sold mine and want another but theres no for sale second hand.

rsnissan

iTrader: (9)

they came with all the quip fittings and were over 500 IIRC

Paul_RS

iTrader: (4)

You can check prices on their site, doesn't list hoses though? I think RSnissan is pretty close, but i heard they are £600+?

Not cheap!

JTECH James

iTrader: (13)

prices on their website hey.....

rapidcossie

mine was almost 500 quid and it didnt come with all fittings!

bailey1

iTrader: (2)

well my problem is i have rebuilt the engine and have had the turbo rebuilt but im still getting puffs of smoke when cold on idle and when hot on idle but not under load or after boost etc so im trying to source possible backpressure or lack of oil to the head as im also getting a very slight cam rattle from what seems to be the rear of the head but only very slight the second you toch the pedal and i do mean touch it clears and if driving theres nothing.i have checked everything you can think of but the only thing that remains the same and untouched is the breather system and its the first time i have come across the setup hence trying to find out if its ok ??? the engines only running stage 3 it has good oil pressure etc etc but im still experiencing these problems they are fairly minor but i am a bit of a fussy c**t lol and likes things to be perfect lol

rsnissan

iTrader: (9)

having a quick add up on their site and NOT making my own hoses up (+ GGR tax) I can see it being closer to 700 all in.......

JTECH James

iTrader: (13)

rich map maybe?

bailey1

iTrader: (2)

mine might be for sale shortly lol mine has all braided hoses with aeroquip fittings even the rocker cover is blocked of with a aeroquipe fitting.

You need to breath from more than just one port in the block imo. also the pipe going from the seperater to the catch tank i think will be acting like a U bend in a toilet and not really allowing any air to pass through.

I also think you should breath from the rocker cover too.

bailey1

iTrader: (2)

thats next on the list a rolling road setup to see whats happening think i might upgrade to level 8 while in the process closed loop wasted spark etc then get it lived mapped but a tad extreme .what the hell 2 birds n one stone and all that

JTECH James

iTrader: (13)

all makes perfect sence!

Nash

iTrader: (3)

What pistons were used in the rebuild?

Let me know if you sell it mate

JTECH James

iTrader: (13)

nash is waiting for a wossner reply

Nash

iTrader: (3)

I hope for his sake it comes back with anything but the Wossner reply.

Although mine was quiet when first built it. Did smoke a bit at idle for the first 500miles though when cold.
