    I helped my dad put one of those 215's (in this case an Olds) into a Volvo 240 wagon. We are in the process now of moving it into a better body and converting it to a manual gearbox

    So, should we solve the carbon build-up problem in the MCS by putting in a V8? :lol:
    In the late 1960's I recall autoshop talk about someone in Los Angeles who put a V8 in the back of a classic Mini. Never saw it, so it could have been urban legend.

    Why yes I think so and a little water treatment.

    Hey Matt (Dr Obnxs) has already engaged conversation to do such a project? So who knows ya might see a thread "How to V-B your MCS" by him in the future? :lol:

    So, this would inject Vitamin-B in my MCS? You think that would help? :confused: :lol:

    The mini is just stressed out a bit and has some plaque buildup.

    Doctor recommends some fresh mountain switchback air mixed with heavy on the throttle action.

    it seems to be a common problem on DI motors
    Audi has this problem also if you do a bit of hunting
    the 3.2L motor they build is the worst offender.
    I know Crevier has multipule Prince motors on hand simply because of this problem

    So......My question to this carbon problem ,will there or can there be a solution to "fix" .Come on now ,we are a tech savvy nation and by this point has'nt someone come up with a solution.I think if this is solved it would undo the" bad rap" our MINI's (gen 2)are getting in it's reliability/reviews report.:confused5:

    Until they can change the a/f on the r56, it is an ECU safety valve. Wanna stop carbon build up, and help save the engine?? Add a water/methanol system.

    Just me............................

    Just curious, other than saving $10 on a bottle of Seafoam, is there any advantage (or disadvantage) of using water instead of Seafoam, as Nitromini originally recommended for the R56 engine?

    LOL... we used to call the water induction a " Calif Tune Up", way back in the day!!
    It worked then and still does today!!

    If you decide to use water... then look into an water/methanol systems.. there are some at a good price for proven systems.

    Just me...........................
