Hi Guys,there is a brand new GTT 'Oil Catch Tank' for the MCS coming soon. It has 'left the drawing board' and production commences this week. Initial batch should be ready by the end of March. It incorporates many unique features which should put it way above current offerings. Rest assured it will not consist of a short length of silicon pipe with an alloy cap 'jubilee clipped on' at each end.
I will put up the spec later on (no pics, as not made yet)

Firstly though ,why do we need one?
As standard the oily mist from the crankcase passes through a one way valve (PCV valve)
positioned on the rocker cover via a part rubber & part plastic tube to a connection
just upstream of the SC rotors. Inevitably not only are fumes & air passed through but
oil; this is bad news for two reasons.
Firstly it lines the intercooler and rubber bellows with oil reducing efficiency of the intercooler,which can make the bellows more prone to slipping off.
Secondly ( and less widely known), most of this oil actually passes THROUGH the S/C and Intercooler ,into the engine & burns! This is far more detrimental to performance as the oil mixing with the fuel during combustion LOWERS THE OCTANE OF THE FUEL. This at best means ignition timing will be retarded to stop it knocking /pinking,(lowering power output in the process,)
OR worse still,will induce knocking/pinking with possible long term engine damage .
If you check your spark plugs (doing a proper plug chop),they should be a light to medium grey colour. If they are more 'biscuit' or tan brown colour,with 'deposits' ,this indicates burning oil.
If the Intercooler has oil in it ,you can bet the oil originated from the breather system.
Enter the GTT ' Oil Catch Tank'.......

Will be awaiting this anxiously just to see it.
I say more innovation.

Roland, I live in the US but would be very interested in a well engineered catch can. Two questions, will I be able to buy one of these to ship to the US, and could you PM me with more details? Thanks and good luck.

[roland2003]

yes,'Innovation With Imagination' is our phrase.
We can ship anything to the US, will post up spec tommorow at the latest.

GTT OIL CATCH TANK -SPEC.
The unit consists of an aluminium body,of taller than usual dimensions to reduce emptying frequency. Rather than the usual 'sight glass' (sight plastic) which can both collapse & leak at the unions with the vacuum,we have incorporated a neat screw in level dipstick . It also has a drain plug positioned near the base. The top section bolts to the tank body & incorporates an O ring seal. Inside a supported baffle plate is positioned part way down with an aluminium delivery tube delivering all the oil BELOW the baffle,a stainless gauze is also used below the baffle to further assist with skimming off the oil.The exit pipe is flush with the top making it almost impossible for any oil mist to get out.The top,baffle and tube all come out as one,enabling easy cleaning plus the option of using stainless steel gauze below the baffle.
The unit is positioned in the engine bay,and bolted to the chassis with an integral
bracket. The OE earth lead is repositioned slightly.The unit has no visable welds and is hand mirror polished.All fixings and pipework is included. We believe no other design will remove (catch) the oil more effectivly nor be more user friendly/reliable. The GTT build & finish speaks for itself. Price TBA

Sounds like another quality product Roland - keep up the good work

[roland2003]

After some final thought ,we have decided not to use a plastic 'sight glass' (as on other makes) to monitor oil level. This is due to reports on others of the sight tube sucking in /discolouring/ or leaking 'sight glass' unions; caused by the negative pressures inside the catch tank.
Instead it will feature a Screw-In Dipstick to check the oil level - How Cool Is That!! Regards Roland Gt Tuning

Its actually cute
could you make me a tiny intercooler aswell.. lol

If this is occurring and/or has already happened in our MCSs, does installing the oil catch can reverse this, as well as prevent it from occurring? It sounds like only those with the newest cars would benefit the most from this, because they have not reached the stage mentioned above.

It will not reverse the buildup.
It is not hard to remove the buildup and then install the catch can.

[roland2003]

Whilst fitting the Catch Tank it would be worth removing the Intercooler and bellows where the oil collects to clean the oil away using say brake cleaner & an airline. Once done hopefully no more (or at least considerably less) oil will get through.

Will we see pics soon?

[TallAndy]

Any updates on the catch can roland?

Is it similar to the alta solution?http://www.altaminiperformance.com/p.../CATCHCAN.html

[roland2003]

Hi Guys, no pics but are in production. Its about as far removed from the Alta design as you can get. ( a good thing )

Hi,

I certainly hope it is not similar to the alta

Cheers

how do you fit an oil catch tank??
how much will this cost??
sounds great
can the collected oil be put back into the engine or is it disposed?

Cannot be and shouldn't be put back

[Cooper S Ire]

hi any further info on this like price and where and when
we can buy this

[stu(pid)]

Any update, Roland?

[roland2003]

Hi Guys, yes sorry for the delay on this one,we are cutting metal as we speak so wont be too long now . Price is £85+vat. They will be available direct from GTTuning
