Oil tank leaks right where the bottom hose plugs into the tank, old grommet seems to be excessively loose. Also the oil sensor fits loosely in the top hole as well. tried some degreaser to clean off the sides of the openings with a paper tower. used home silicone, and permatex black oil resistant gasket maker but it doesn't seem to stick to the oil. any advice on sealing the oil tank would be greatly appreciated
