Has anyone used this product as they rave about it in america but i haven't heard of anyone over here using it, any problems it can cause
I'd be more worried about flakes of hard carbon going through my exhaust turbines![/QUOTE
i've got a new turbo going on in a few weeks
But then thinking about it i have seen headgasket failiure where the affected cylinder is spotless, so in theory it will work, just sounds odd.
thats not the main benefit though. when you do the internal steam clean you clean a lot of crap out from the rings too. with all that out, the rings can expand fully and seal better.
