mbw479 Posted September 30, 2019 I have installed a couple piston with a moly coated skirt (see pic), I have dropped the oil to check it after .5hr run time and noticed some black specs in there. I am assuming this is some of the moly coating of the skirt, it’s not a lot and I’m not too concerned. Just thought I would check and see if anyone has some experience with these pistons, and is this normal? Thanks Share this post Link to post Share on other sites
BDubb106 My Ride Posted October 3, 2019 I have never had the coatings come off a CP piston and I ran them almost exclusively in my RMZ’s. Share this post Link to post Share on other sites

mbw479 Posted October 3, 2019 The black specs were mainly on the long screen, with some in the drained oil. Share this post Link to post Share on other sites
