Banjo Bolt for sump plug

[duncan]

Cheers Logan - on the case with them already but will probably ask someone that knows what they are doing to order from them so as to ensure I dont miss anything.

have you tried http://www.pirtek.co.uk they are a hydraulic specialist, i used to work for them years ago. im sure they would beable to sort you out a banjo. i went to them to get my hoses made up for my oil cooler.

and they have a depot in cambridge cant remember where it is, its been a long time since i have been there.

SCA in Norwich, they have Aeroquip on the shelf...or is it Goodridge... or as suggested above, Pirtek.

Guys, this is a proper solution to the oil throw issue that i have.

No datalogging purposes
No sensors
No G loading

Problem:

This has been an ongoing issue with my car (actually probably the only ongoing issue) and goes like this....

When experiencing sustained G right hand corners on track such as Coram or Luffield, The baffled region in the block is fed from a pipe that goes under the oil level in the sump, I guess the idea is that oil caught by the baffle returns to the sump. However, on hard launches or sustained cornering the outgoing blowby gas can take with it a drainpipe load of oil with it.

This oil is gulped out to my catch can rather than into the intake manifold as in the std arrangement (which is what I wanted). However, If I do more laps than the capacity of the catch can, it fills up and starts blowing oil straight out of the breather pipe under the car and onto the track.... not ideal for me as it caused me to spin on it at Snetterton or could/would do the same for others

Solution:

A different and a lot bigger catch can is needed with 4 inputs and a drain hole at the bottom.

The drain hole will feed the collected oil back to the sump where is is free to re-circulate via an aeroquip hose fed to a banjo fitting on the sump plug.

I have found out the fittings required for the drain pipe/bolt:
1x BA7-M20-10 Banjo adaptor M20 Bore x -10JIC
1x BBA2-105 M20x1.5 Alloy Banjo Bolt
1x FBS1600 1" ID Firesleave (optional depending on routing of hose)
1x -10 braided hose to length
2x dowty seal washers for the Banjo Bolt

Any of our suppliers get this gear?

This will be fed by a Roger Clark Motorsport 2.6 Litre Catch can with 3 inputs, 1 large bore breather and drain plug mounted to the left hand chassis rail.

This will once and for all sort the problem as it is annoying me now.

Just thinking about the variations in pressure around the sytem, would the sump be at the same pressure as the catch can? could the oil be forced from the sump back up into the catch can under some circumstances, what about fitting a check valve?

JC - the breathers going into the tank will keep it pressure neutral in the most part and from the range and experience of impreza tuners (RCM, Zen, Bob Rawle, John Felstead, etc etc) that have this exact arrangement, I am comfortable that it will not be an issue.

All parts have been priced up and will be ordered & fitted soon (ish)

There is nothing essentially wrong with my current catch can arrangement in how it works as it is separating oil vapour from the inlet to prevent it causing det.... its just the can fills up quickly on sustained high g corners (and that is only going to get worse with sticky tyres and suspension mods)

[JC]

Sounds like a good plan then, another place is Lowestoft Hydraulics or Parker Hydraulics in Norwich.

Thanks - should have said ... BigPower supporting supplier chosen too - full info and photos will be in the project thread when done 8)

It constantly amazes me the range of suppliers and members skills we have here .... love it

[duncan]

I have sorted it already Alyn - thanks for the offer.

Just need to find a way to get some discount out of Roger Clark Motorsport now
