sqrlgtr 3,208 #1 Posted 4 hours ago Is this just and extra oil drain plug on bottom of block and has anyone been able to snug it up without taking motor loose from frame. I fixed the drain pipe to block while I had it tore down for some much needed preventive maintenance, But I missed this one. This is on a 520H and it is leaking some but looks like its blowed up with that drop or two of oil dripping and getting blown around Share this post Link to post Share on other sites
