I've just brought an oil catch tank of my 98 classic uk turbo,thinking there will be instructions on how to fit, but NO so any help would be greatful breather pipes from and too please

 

I'm in the same boat ^^

Help us please!!

 

We can't give you specific instructions, because we don't know what type of tank you bought and what sort of connections it has on it. You're probably going to have to use an element of your own initiative.

You can find the breather pipes easily enough - there are two leading from the black plastic covers at the upper rear of the cylinder heads, and the third one is at the back of the cylinder block next to the turbo. They'll be linked together by pipes under the inlet manifold.

You then have to deal with the PCV valve and connection to the carbon canister, along with possible return to the sump.

Have you checked the FAQs to see if there's anything that applies to your chosen can and car?

 

What can you bought?

i have a japspeed and heres what i did as its 2 port

2 x rocker breathers = VTA These cost me £6 from ebay its self explanitory where they go - on the 2 rocker breathers. You now need to plug the hole that go back to your inlet hose where the hose from these went (two into one, so only one needs blocking)



Your crankcase breathers the main offender of chucking oil back into your inlet tract/manifold via the pcv valve just below the TB - stick your 15mm tube on to this and vent it to your can. I did this to my can to 'catch' the oily vapour. just a bit of spong and a piece of hose to the bottom of the can. the can, can now VTA or re-circ whichever you you choose





If you do a seach, theres diagrams etc on how to do it which are useful, aboves how i did mine but everyones different.

 

I have a can like that. Where did you mount yours?

 

one of the bolts on the ABS pump. although that may change

 

I found this write up about a Newage Impreza very helpful... its basically the same as the classic. However when I do it I wont be returning the pipes from the can back to the intake the cans will vent to atmos via a breather.

mine is like yours wrighty 2 ports brought from scooby world, so could i have the crank breather going in the the catch tank and back in one of the rockers and the other rocker breathing in to the air like you have?

 

dont understand what you mean mate

each breather, breathes oily vapour back into your inlet tract, so not sure why youd put the one off your crank into the can then back into one of the rockers

Both my rockers are those two little filters and are VTA
the crankcase now goes to the can, and is also VTA

 

had i look at another scoobs set up today and both rockers are linked and the crank only goes to the tank which then goes to air

 

This is what I used when I fitted mine. Both rocker breathers and crankcase all into 1 pipe - then the outlet on a small breather. Ideally located away from the engine bay so not to get smell of oil in the car...



Hope this helps

 

Thanks tucker82 i think i under stand that, where/what pipe did you use? does your system work ok? where have you mounted your tank?
Thanks for the info

 

I've not got any pics yet, as it was only in 2 weeks before I took my engine out!

I mounted on the drivers side inner wing where the airbox would be (FMIC). Used a blue silicone lined 15mm hose with a couple of T pieces. In the pic it shows that the two rocker covers are joined with an existing metal pipe. Mine had a plastic pipe that split and went into the turbo inlet pipe. I took all that out, replaced the inlet pipe with a samco 90degree elbow and resonator delete pipe.

I now have from passenger rocker - Tee from Crancase breather - Tee from drivers Rocker cover - into catch can. Outlet on the catch can with hose and small oil breather. I am yet to relocate the breather as it does kick up a bit when driving!

this is going to sound stupid what is an oil catch can why would i need to fit it and how much some1 pm me.

 

Oil Catch can is to catch the oil vapours that come from diffrent points on your engine. Your oil breather pipes will direct the vapours into your turbo inlet hose - then its dispersed from there. There is no performance gained in fitting a catch can - it just keeps your engine bay cleaner and is a nice bit of "bling" too. Maybe somebody has some pictures?

I got a 2 port Japspeed tank on a GB on here but there are many types about. Prices start @ £30 + (mine on a GB was £48 IIRC)

You also have the cost of hoses and T peices, oil breather filter & the time to fit/ cost of getting one fitted

Oil vapour in the inlet tract obviously will end up mixing with the air/fuel mix and unfortunately lowers the octane rating of the fuel and therefore the A/F mixture's resistance to detonation. So running a catch can/oil breather system is very much a good thing.

 

Has any one else got the catch tank? just getting an idea of how every one has theres and where they have mounted it but thank every one for the input

 

I got mine from here:ebay clicky


Good quality tank but wasn't intending on using the mickey mouse tube or the flimsy bracket.

Made my own bracket




Mounted it down by the carbon cannister.




Have bought some blue hose ready to pipe it in. Going to join the rocker breathers to the crankcase breather and take them to one port on the tank then vent the tank to atmosphere either through the inner wing or down the transmission tunnel.

I've chose to keep the PCV in place under the throttle body as I use the car daily and most of the time it's off boost.

 

What are the good and bad points in keeping the PVC or bypassing it? you said when it's off boost.

 

Taken from Andy Forrests web site as it would take too long for me to explain

Quick intro:
Off boost:
On boost:
Or just have a look here: andy forrest performance

 

ok now what do i do? keep it or bin it? the car is only in use at week ends but i do like to have a play with her on full boost but not all the time and it's not every weekend, so i think i might just keep the PCV as the car does stand around abit in the garage

 

no harm blocking it off imo

 

Depends on what you want to do. I'm only interested in keeping the oil out of my intake pipes and FMIC so chose to keep the pcv.

 

If you are worried about it, you could always give the intake pipes from the air filter to the turbo a good blast with carb/brake cleaner once a week, to remove any vapours.
