Sump oil return - big wing
Where have others positioned their fitting for the oil return on a big wing sump
Mine is away being modded now and need to know where is the best place to put the fitting so it doesn't foul anything
The separator on mine sit's behind the turbo so is on the exhaust side wing and would ideally like it in one of the sides at the bottom below the oil level
Cheers
Pics would be great

The only problem i have with the inlet side is the separator isn't on that side
I have decided it's going in the wing on the exhaust side as i think it will miss the steering linkage and the hose will slot through and come up past the downpipe to the base of the separator
This is the separator that sit's behind the turbo

why have you had that fitting welded there ,now if you put the bottom pipe to the big wing sump you will have problems like i did , it will fill the header tank with oil and keep pumping it out till you got none left in the sump and you dont want that the spec-r breather you have there is NOT desined to work like that iv been there and done it give me abell if you want

hi dave i dont understand what you getting at there?
brammer has a oil seperator as well as the catch tank.
the seperator will seperate the oil and air and brammer will have only air and crap going into the catch tank, no oil at all.
the fitting he has welded on is'nt in a good place because there's a plate inside the catch tank to seperate the crap from the air.
it should have been fitting to the same side as the other fitting.

Just to say my Catch Tank has a drain Tap right at the bottom, ive opened it a couple of times...only a very small amount of clear water comes out.... told recently by specialist in these Engines that the water is Condensation that builds up...normal. OAP Pete
thats what i don't understand what dave is saying, the tank will fill with oil?
surely then if the catch tank is to collect vapour and water - it doesnt want a return into the block ?
wont the standard breather return on the block suffice for oil return from breather ,
then simply drain the c-t as and when

brammers catch tank does'nt return to the block his seperator does

I'm plumbing it to the block for now and not the sump - although i have had the fitting welding into the big wing sump just in case.
I just can't get my head around it so i'm fitting this way for now.

Just today if any help looked carefully at mine...the very lower Pipe from Chrome collector, just seen in my Picture of Car, goes to a brazed in adapter on top of the right hand Wing of sump [looking from front]. All fitted by Engine Tuner "Harvey Gibbs" Peter.

I know Tony replied on another of my threads regarding this setup i'll find the quote.

Tony's input from the other thread
the crankcase pressure you refer to is equal no matter where you stick your fittings
The engine is merely an odd complex shaped container. Try to picture your engine as a simple container.
If you have pressure in your crankcase your engine is either fooked or your breather is crap and cannot flow sufficient gases.
your crankcase pressure should be no more than 1 atmosphere or to the layman 0
ideally some negative pressure is preferable which is what a new standard cosworth had with it's breather design on engine decel

a simple fix to the ggr and spec r systems is to convert your catch tank into a separator. This is quite simple you need to modify the catch tank by fitting a -10 fitting and pipe to the lower most point of the tank ie convert the drain tap /drain blank.throw the tap /blank in the bin.
Pipe this new -10 fitting back to the convenient crankcase fitting on the block by the block coolant drain plug. you will need to heat wrap the pipe and also make sure it has constant fall and is routed clear of the exhaust and manifold
If you are already using this point on the block you will need to T into it making sure the priority flow is from the catch tank.
IF using a ggr catch tank you will need to add a second -10 min fitting on the upper most corner of the tank to atmosphere.
The spec r catch tank does not require this as it has huge atmospheric flow just pore crankcase flow.
By carrying out the above modification you have also increased the crankcase flow.
I hope the above is easy to understand
you have now converted your breather system to the Turbo systems design of the 80's era

Managed to get Pic...i see now there is an angle [L] in the Pipe...difficult to see from above. by the way the sensor in front of it is for Oil Temp Guage... Hope OK Pete.
