Re: Yanmar 2GM20F Oil pan leaks
All of us Murphs have a special vulnerability to the law BUT I did manage a complete ring job on my 3GM30F with the engine in place. Your pan may well drop down in place which makes a new gasket a fairly easy job. Just drape a cloth to catch the inevitable dropped bolt, lay a mirror in there along with a good bright lamp, and go easy with the 10mm wrench. Pan bolts usually come out without a fight because they rarely get rusted in place and are not torqued very much. For any rounded off heads on marine engines I've found it pays to keep both U.S. sized wrenches and metric for those in-between sized rusted bolts. Also make sure you have 6 point sockets, not 12. Put it back together with good gasket cement. Gasket cements have come a long way and can be used with or without a paper gasket.
