17xpt. Noticed oil residue around valve cover oil cap. Is it just me or does the oem oil cap not fitting tight enough?? by RR | Mar 23, 2018 | RZR XP Turbo | 0 comments Seeing if anyone else is having a issue with oem oil cap on valve cover.to me it’s not going on tight enough and letting engine oil deep out. Dirt getting in possibly. Solution/ fixes Sent from my iPhone using RZRForums.net Utah RZR Rentalswhence Submit a Comment Cancel replyYou must be logged in to post a comment.
