    So after taking my intercooler off and the plastic tube that goes from the throttle housing to the super charger I was amazed how oily it was. The throttle body took forever to clean as did the rest of the components. I know lots of people think a catch can is not needed but I am no longer convinced.

    Has any here used a catch can long term and been able to see if it does help keep everything clean?

    As a side note I replaced my bypass valve.the one that was on the car was very easy to open. The DT one is nice and tight. This should help on early boost.

    Make sure to buy an Alta Lee. :smilewinkgrin: I'm not convinced one is needed.

    It was double edged sword for my 2nd gen pos.

    Do you want higher crankcase pressure with increased oil consumption or do you want an oily intake with dirty valves?

    I've had a oil catch can on my series two MINI since it was new, it loses a pint of oil between 5000 mile oil changes.

    If your series two MINI S uses oil with an oil catch can and doesn't without an oil catch can, then your head cover/PCV is defective.

    An R53 doesn't get dirty valves like the N14 & N18 engines do. It is port injected not direct injected & that's why. I have seen zero proof that a catch can on the newer MINI makes any difference. Use them if you want.

    The Intercooler boots had oil sitting in them. But it has been 2 years sense I have it off. The inter cooler is dirty but not to bad. I will clean it before it goes back on. It would be nice to keep some oil out of the system. It makes me long for the days you just stuck the crank case vent hose in an oil can and were done with it.

    Perhaps I am being too picky.

    I had the same issue Saturday, pulled the old IC boots for their replacements and found oil, not a whole lot but it made me wonder a little.

    After I first took off my inter cooler and boots on my gen 1 and saw MCS02 saw I added a $5 catch can (water/air separator from Harbor Freight). The last time I had it off it was much cleaner. It was worth the $5.

    A little oil in the IC boots is normal. Every time I take mine off I see a little and clean it out but, It's no big deal.

    No oil catch can needed on an R53.

    After I had my intake valves cleaned I purchased one. Can't say yet whether or not it will keep them clean(er). The can itself didn't do/catch much at first, it's a pos M7 carbon can with nothing inside it. No baffles, nothing.. And the out/in are right next to each other with nothing separating them. I crammed it full of stainless mesh and I check it every oil change and so far it's real dirty inside and the mesh is oil covered but it hasn't separated out enough oil to even register on that clear side hose thing since the Dragon. I did notice that the pre turbo tubes are oil free now.

    We are only talking about Lee's 1st Gen R53.

    We all know the later version Turdblow cars have many issues. :lol:

    How much $ can a catch can catch if a catch can could catch earl....

    I'm thinking they are just engine jewerly....

    Something to stand around and talk about with the bonnet up and a beer in your hand.... Then they would be worth it...

    If Greene Performance comes out with one then they must be beneficial and I would edit my post....:Thumbsup:

    Drill a hole in the bottom of those boots so the oil can leak out. :ihih:

    I've had one on my car.....ebay special.......for better than 10 yrs now and it gets about 4-5 oz of oil each year or so. As long as you connect the can to the connection with the hard plastic line under the IC you will never have a problem
