Arma 134 Report post Posted February 28, 2020 Anyone here done the rocker cover gasket replacement on an N55 (in a 2012 M135i) and able to tell me how labor intensive it is? I'd like to tackle myself but have limited time to be without the car atm so will take to the shop if it's too big of a job. I've seen a few videos and they all seem pretty fidgety in terms of just getting clearance to remove the parts. Smelly burning oil and little bits of white smoke coming from engine bay is what is making me assume it's a RCG leak, but still need to confirm Quote Share this post Link to post Share on other sites
