    Searched around on this topic from google, but i haven't really gotten a definite answer or it doesn't have one at all lol. With the b series being over a decade old, have any of you guys done this to yours and whether or not it's really worth the effort? I change my oil every 4k miles and check the dip stick every so often... What worries me is the fact it turns black almost immediately after a long drive. <br />I know it's a different opinionated topic so just want people's advice and flames

    From my understanding it will clean it out but in the process it could block your oil pump up due to the old :thumbdown: being flushed through

    I'd say no , but if you research into them and don't stick any old one in maybe , I service my k swap every couple months and oil comes out uber clean

    i wouldn't bother, especially with it being an old engine and probably never had a flush before in its life, it'll probably kill the engine!

    I was told by someone who knows their mechanics that it will do more harm than good, one you are revving it for a good 5 or something minutes and that it can wear certain internal parts out.

    ^ engine flushes are put in and are left to idle for 15mins ... Not ment to rev them at all

    It can lead to clogged oil galleries in the block, you'd be better off flushing oil of the same grade/weight through if that's what you want to do. Not to mention the fact that there are certain parts/bearing surfaces within the engine where you wouldn't want oil cleared from.

    Hmm... I guess that makes sense, captain_slow. Indefinite answer would be not to use engine flush then. Was thinking of using some cheap ass asda oil to do it as well!

    wat like wyns engine flush, i did it once on a honda legend with 150k and it never did it any harm but no way would i put any cheap flush crap in my k20 incase it did any damage, i think the wyns stuff is like a thinner for engine oil, cleans engine out well but prob not good for the moving parts
