Hi folks, had my engine terracleaned today. They came to the house and went at it for about an hour. When they started the second cleaning cycle after the soak period, a whole lot of smoke bellowed out for a good 8-10 mins. Took it out and caned it afterwards and the difference was really noticeable - smoother, quieter and pulling hard from way down. Early days yet i know but she's in for a service tomorrow so I'll update in a week or so to let you know in case any of you are curious.
