Anyone have any info on whether I can leave the screw out...

    Hi everyone, just a bit of advice needed please on using a damaged piston. Swirl flap damage to top of piston has been smoothed off as much as possible, and all high spots and gouges taken out. This has resulted in the edge of the swirl pot being compromised. See the attached photo. I know the...

    Greetings! Ever since I have owned my 320d (coupe facelift 150hp) it has had a very annoying intermitent fault of loosing boost/power.
