right... well, everyone is entitled to an opinion. official alfa garage that had done my cleaning explained this stuff to me in detail. this is why i think chemicals are bad idea.
Another words just a mechanic with what specialist background research in this field?
basically what they said was - no chemical can make a soupy homogenous substance out of this carbon buildup we call soot. there will always be chipping off.
They how comes it dissolves with cleaning agents i used as also done using cans by other members on here
And again, how come this mechanic knows more than BG and the likes of Frank Massey. Sounds like 'man at the pub told me' stuff that this site gets a lot of unfortunately
two and a half hours very very bad engine performance. a lot of smoke coming out in the rear. sometimes bluish, sometimes downright black. often engine shook wildly. i cannot say why but i kinda got an impression it tried to swallow chunks that were on the limit of stalling it. true, engine ran much smoother after the cleaning, better throttle response and economy but... well... two and a half hour of engine torture... i don't know. i made my choice and done it manually.
Two and a half hours of treatment
So you havent witness it then, or you saw it done wrong. Takes around half an hour and the lumpy running is called diesel knock and wont cause any harm. And the chemical is pulsed at intervals so the engine wont even be knocking for even half that time.
everyone does as they want, right?
Yes you did make your choice and do it manually and im glad it worked for you, but why are you intent on clogging this thread that was for forum members to say where they know it can be done
, with uneducated hearsay and so far havent heard you bring foward ANY evidence
this can cause a shred of harm
If you dont like the idea of it, dont do it. But if you havent even done it or seem/heard of it causing any damage why go on an keep rubbishing it?
Sorry fella, but seems like another Accellera thread all over again
