Rolling up the miles delivering trailers.
Polaris Comments.
Suggest checking compression and for engine breather passing oil (blow-by) or similar diagnostics and monitoring engine fault codes. Chrome is at a SIGNIFICANT LEVEL and is possibly coming from piston ring plating; Tin is at a MODERATE LEVEL; Tin may be coming from Piston Flashing, Bearing Overlay, Bronze Alloy (usually in combination with Copper), or from a Babbitt material along with Copper and Lead. Lubricant and filter change acknowledged.
Polaris is having a cow about 7 ppm of Chromium. I haven't noticed high blowby or increased oil consumption. The only chromium would be on the oil control ring rails. The top ring is moly-faced, and the 2nd is ductile iron. I will see if the high reading keeps trending in the next analysis.
Continuing to run with the EGR valve unplugged, and the soot and oxidation numbers have stayed in the safe range of the previous analysis.
