when it was off, the amount that was on the inside of the head,must of been 1mm think in carbon and the crap that come out of the inlet, i could not believe it,all that from a 50k milage car!

have taken it for a small run today but could see it slowly building up the mpg,have to do a few more miles first i think so it can start correcting its self.

thanks for the info on this lads.
