    If the Cooper is not DI, then do I need to use Seafoam at all?? Thanks for the info about the codes.

    Yes and no

    the downfall of the DI engine with respect to carbon build-up is that the gas doesn't clean the back of the valves. But it also seems that the early Prince engines had crappy phase separation out the valve cover, so they are dumping way too much oil into the PCV lines anyway. On the Tritec, carbon build-up is a problem, but a much slower one than the DI Prince.

    Doc, I saw the vedio about seafoam here and it was being put in a justa, but I guess it was a 1st generation. I have a 2009 justa, so do I not have to be concerned about the carbon since it is not DI??? I'm unclear on this.

    The DI carbon/sludge/Oil deposit problem has been an issue for quite a while. There are companies like BG that make their own chemical treatment and have their own solutions to this problem. I have seen the Audi/VW treatment but these services are basically sold to the customer as an optional procedure. I have been promised a BMW treatment but it looks more like somewhere around December until anything I see anything new.

    I know the treatments do not remove the build up from the back of the valves. Since its not all carbon build up the deposits are actually not that hard and they can actually flake off with the proper cleaning tools. I know dealers are sending the heads out to be cleaned, decked and all the valves checked etc... Removing the head everytime this problem occurs is excessive. To be honest I don t know what the ultimate solution will be. It is a serious problem. The good thing about R56 Cooper S is the intake manifold can be removed pretty quickly and about 90% of the carbon can be removed without removing the cylinder head.... with the proper tools. Obviously if anything new happens I will post

    That was an interesting read. The Justa develops 103 ft pounds of torque at 2K where the "S" gets 177 at 1,400.

    But my question still remains unsnswered. Does the fuel wash the backs of the valves in the Justa, making Seaform un-necessary????? I come from the days of points and condensers.

    It's not as required

    but there is no "yes" or "no" answer. To some extent, the sea-foam on the port injection is not needed, but even with the Tritec, carbon build up would lead to issues, just not like those experienced with the turbo Prince.

    So if you don't do it on the N/A Prince, you won't build up carbon to the point where the engine will kill itself. That said, it still injests more oil than it should.

    Lynn would say blow off the Sea Foam and just use water on a hot engine.

    Anyway, decarbonizing isn't new with the MINI. It's an old, old technique.

    Thanks Doc. At least I know the smoke was not something buring off that should not be. From what you say, I take it that Seafoam is a good thing, but not needed as often as the with the "S", on the Justa?
