turbolizard 38 Report post Posted August 3, 2014 Found this in my M40 sump - Does anyone recognize it? It is made of reddish brown plastic and is reasonably stiff but will flex. Looks like some kind of clip about 15mm diameter. Quote Share this post Link to post Share on other sites
Lubed 55 Report post Posted August 4, 2014 Looks like the plastic clip that comes on new hydraulic lifters that seals the oil supply hole, obviously is supposed to be removed before fitting. Must have found its way in when the rocker cover was off at some stage then been flushed into the sump. Quote Share this post Link to post Share on other sites
