That's not negligible !! 1 psi is 8 bhp

AlanG

So you've been lying all along then Andy?

1.7 bar x 8bhp = 199.92BHP ??!!

Absolute pressure M8 add 1 bar (talking about your engine too )

@Alan G

How does one get an engine as clean as that? dont tell me it was all elbow grease and hard work. do you actually run this engine?

have to say real nice m8

cheers

My offside strut tower is cleaner though

The car's almost four years old!!

It was a daily driver for the first three years, but all i've ever done is give it a quick wipe over with WD40 when i'm finished working on it. (honest!)


Alan

AlanG

and so it should be you're car is 2 years younger than mine!!

You know what i'm gonna do now though....since you've pointed it out....

fao john trying to look at the routing for catch tank.
there are 2 pipes on the intake pipe.
1.has 2 pipes running from cam covers to middle of car to t pce under the inlet manifold then single outlet to inlet pipe.
2.is small pipe that runs from the block to the inlet pipe about 4in long near the turbo.
which one did u use for the breather system and how.photos of connections on ur new digi camera wld be great as i am not too technical..thks paul

AlanG

John used the one from the crankcase breather.

On the crankcase there is a very short piece of pipe which attaches to a three way connector. One part of it goes to the inlet manifold, the other returns to inlet pipe. It is the return line to the inlet pipe which is now going to the catch can.

Alan

AlanG

This should give you an idea.




Alan

thks alan what have u done with the hole where that breather went back into the intake i see ur new pipe runs to the catch can but what about the other pipe on the can..thks

john banks

NINJA - you can see the bolt blocking off my inlet pipe on one of my fotos. Whilst there is nothing in my catch tank, the intercooler pipework IS staying clean unlike previously. Maybe the oil mist if just going straight through and not depositing. I am puzzled, but somehow the thing isn't clogging with oil, so I am in no particular rush to lift the inlet manifold to do the cam covers properly.

Has anyone had heat related problems over time with the cruddy looking (water?!) hose Cusco supply?

Thanks

NINJA

john i am guessing that u are venting to atmo with ur catch can.did u consider running the return pipe back to the intake(green mode for emissions etc)my rocker breather shows no oil anyway it is only the crank that has a bit so guess this is the big offender.i was considering running rocker breather in catch can as well and returning both to their orig postn on the inlet.
theory being any oil drops into catch can(by gravity)then fumes go back to inlet pipe clean????

john banks

At high boost as Andy says it is more a mist, and I don't have anything in my tank, but my inlet has dried up, so not convinced recircing them works. It is the only green method though.

You're kidding yourself about the 'green' stuff The breather gasses are only the same as your exhaust. In the absence of a cat, you are causing no more polution with VTA than vent to intake.
As long as it's not dribbling oil on the drive then I'd VTA, It will give you 'slightly' more power

As an aside (which I hope will never be of value !!)
VTA will also mean that you can 'smell' if your engine is starting to develop a problem. I caught my piston in the early stages before it caused any damage, if I had VTI then the oil would have been consumed, probably caused det and may have broke things in a more dramatic fashion !!

Andy

NINJA

on a vta system what have u used to block the hole in the intake

Andy.F

Originally, I crudely stuck a bolt up the pipe !
Later, when I had the manifold off, I plugged the hole with a capscrew.

AlanG

NINJA

On my car i made up a new inlet pipe which doesn't have any other pipes coming off it.

So... the rocker cover breathers go to a 'T' piece, then to the top of the catch tank.
The crankcase goes to the side of the catch tank and both pipes vent to the floor area of the bulkhead.

The re-circ dump valve then became a VTA.

Where's 'la-la-land' ?

Just added a catch can.. well bottles actually.. a bit Heath Robinson but there you go.

Was getting a fair amount of oil in my intercooler and pipework..

Question is.. have I added the pipe to the correct one? done the cam covers no problem.. but assuming the pipe with the square angle connector on it in this picture is the crank case breather??



Noticed the AFR has increase.. and seems to shoot up quicker.. which hopefully is a good thing or I have goofed and connected the wrong pipe!

Top pipe in the pick is the cam covers (the one disconnected in the pic) and the one below it I believe is the crank case.. please tell me that is correct?

did anyone draw a diagram like how bob has it?

This old one again..

Andy what did you do with the valve in your inlet manifold.. get rid???

Yup. That's the crankcase breather connection

Alan

Blank plug it

Cheers.. was thinking it couldn't really be anything else..

Was then thinking.. hold on it's not the vacum for the brakes is it :OMG: but then it is sucking slightly at tickover so decided it couldn't be.

On the original air filter system there is this black plastic box like a resonator which is after the MAF and just before where there two breathers connect in. It had two extra pipes into it.. one goes to the boost controller and another is a fairly large pipe up again from under the inlet.. any one tell me what that one is??

I have piped off the two that had oil in.. just wait and see if I catch anything now..

Cheers

For a laff my Heath Robinson attempt! feel free to laugh..

The oil I wanted to eliminate


Dribbles! more like runs..
sorry you have to place your left ear on the desk to get the picture up the correct way


Lefthand catch bottle... crank case and lefthand cam cover, plus overflow / release of fumes etc..


Righthand catch bottle, right hand cam cover, plus over flow..
or is it that my engine is on coke.. cherry coke..


one amusing engine bay, tiny intercooler and coke bottles LOL..


It was intended as a temp fix to see if the oil was still coming out the breathers or if it was from previous overfilling and still weeping etc.. done about 40miles so far and not a drop in the bottles..
and the AFR is quicker to go to rich.. but not peaking higher..
car is pulling harder.. I was expecting no extra power so it is not in my head.. my theory being that my engine is blowing past the pistons and putting a fair amount of air through the crank case which was going into the air intake after the MAF... car has done fair few miles etc..
Could be complete bollox but sounds good to me and I am happy..
might actually buy a proper catch can now... but then again..
Tempted to get small filters for the overflow pipes though as the crank case for sure sucks in air on tickover.

Thanks for the help from this thread

Amusingly I just refitted mine this evening as the oil has returned!

The bottles remained empty the first time they were on so after a month or so I took them off..

Managed it all with one bottle this time.
