oil-fix

"The" Oil Fix is a simple device that fixes problem leaks associated with the base gasket. With the oil control jet installed into the crankcase, the oil doesn't touch the gasket, thereby no leaking through the base gasket. The small end of the "The" Oil Fix oil control jet is installed into the oil return hole in the case, and the big end fits up into the barrel. Then the oil flows through the jet, past the base gasket, and into grankcase

 you can on using metal or silicone beaded gaskets, Remember, "The" Oil Fix is for evo and Twin Cam 88's - not designed for Sportsters
