Digger 66 3,476 #1 Posted July 14, 2016 Just wondering if any of you have had any experiences ( in any type of rebuild situation ) with a ceramic coated piston(s) ? I overhauled the top end of my wheeler last year to correct a piston slap / scoring issue . I'm just wondering if anyone knew if there should be added( or reduced ) piston to wall clearance because of the thermal differences of the ceramic . Any comments would be well received . Thank's all . Gene Share this post Link to post Share on other sites
rtfbg 744 #2 Posted July 15, 2016 Used to work for a diesel shop in Pittsburgh .. ceramic coated pistons were one of the main adds to increase performance of diesel engines, but I have not seen or heard of it's advantage in gas engines. This is a good read .... http://www.engineprofessional.com/downloads/ep9/EPQ110_34-40.pdf 1 Share this post Link to post Share on other sites
